Sawdust call chips, which remains as a result of woodworking. Watching sawdust for roofs, floors and other surfaces is used for a long time, they are perfectly retaining heat, isolated wood resins, and also play the role of a baking powder.
In the old village houses, overlappings, made of a mixture of clay and sawdust, serve for a long time without damage. In industry based on sawdust, wood blocks, sawdust granules, arbolit and opilk concrete are produced. The main advantages of sawdust are their thermal insulation qualities and low cost.
Sawders are widely used in everyday life.
Several major areas of use of sawdust can be distinguished - ranging from agricultural, and ending with construction (sound and thermal insulation).
Watching sawdust - traditions and modernity
It is now difficult to find a more economical insulation, rather than sawdust. At the moment, various building materials are used for the insulation of floors and ceilings of premises, roofs, wall structures and intercharishes. However, it is the sawdust as a heater in a mixture with chips and slag are the most economical raw materials for the insulating system of structures of almost any kind. Of course, in the XXI century, the use of sawdust for insulation may seem like a tribality, but no one has canceled the beautiful heat and sound insulation properties of the tree and its purity from an ecological point of view.
For example, the ceiling insulation sawdust is a good way of thermal insulation, which is involved in a long time in the construction sphere. You can argue about the pros and cons of this option for a long time. Sawdust are often used in the construction of residential and economic buildings. Naturally, this technology implies adherence to certain rules.
Sappets fall asleep hard-to-reach areas: first they are mixed with other components, and then they are tamped. The wood unit is obtained with excellent physical qualities.
For insulation of the house, the saws prepared accordingly are used. First, the raw material is processed by an antiseptic, then it is thoroughly dried and stirred with the so-called. "Lime-fused". The latter is necessary in order to protect the thermal insulating system from pests.
Watchwords in pure form can be insulated with floor, walls, attic, overlap and various hard-to-reach areas, where it is impossible to use another insulation.
Sawdows have only 2 disadvantages - they relate to layers without impurities that have not passed processing. Dry clean sawdust flammable and rodents multiply in them. For this reason, the sawdust is mixed with cement, lime either by plaster and moisturized with antiseptic solution. The finished mixture is not susceptible to fires, and the pests avoid it.
Apply insulation sawdust is best in 1-storey frame houses in case of independent construction. For work it is necessary to prepare the following:
The layer thickness affects the local average annual temperature and the functional purpose of the building. For accommodation in the warm season, it is enough 25 centimeters - overlappings and 15 centimeters - walls. If the house is envisaged permanent accommodation - Then you should increase the layer of up to 30 centimeters. For this purpose, racks are added to the frame, which formed additional filling volumes.
Plots of electrical wiring and flue pipes are strengthened with materials with fire-resistance. The electrical wiring is best hide in the pipe from the metal with a wall thickness from three millimeters. Fire hazard places - switches, sockets, heating wiring, etc.. You should post up using non-combustible materials.
In vaporizolation there is no need - cement in solution absorbs excess moisture, and the tree block will be stronger. When the sawdust fresh, they contain substances that do not give cement to bind to water and the mixture is performed fragility. Therefore, shells give to stand 2 months or slightly wetted with liquid glass.
How to perform insulation sawdust
The solution for filling is prepared as follows: sawdust - 10 buckets, cement - 1 part, lime - 1 (or 0.5) buckets. In the process of mixing, the sawdust is enveloped with lime and cement. After that, you need to dissolve the antiseptic in the water and spray the water of the garden watering can.
After stirring, the mixture must be tied with hand. The mixture is considered ready when the lump does not scatter and it is impossible to squeeze water out of it.
Then sawdust fall asleep in the necessary places and layerly tram. The full ripening of blocks occurs at least 2 weeks, while it is advisable to regularly ventilate the room. After the mounds, you need to wait a few weeks to make sure that all empties are filled, and shove the missing.
From wood sawdust you can make a warm plaster: water, cement, clay and newspaper paper are added to them. Such plaster is used in the internal works. From the mixture you can also produce sheets of the desired size in the forms, to ravibly and give mature. Sheets are used at their discretion as thermal insulation.
Heat sawdust floors
The insulation of the floor with sawdust in its pure form you today are few where we will meet, because the tree has a property easily flammable and burn well. Now, on the basis of sawdust, various insulation are manufactured: sawdust pellets, slab insulation (arbolit), eco.
Equata makes it possible to warm the flooding floors or manually. Here you will need a special blowing apparatus, and you will have to resort to the services of professionals. Acquisition of a whole device for one-time use is unprofitable, and with a manual method, the material consumption is more than 40 percent.
For the area, where the temperature in the winter period does not exceed -20ºС, it will optimally make a layer of insulation thickness from 15 centimeters and more. If you live in more severe weather conditions - Here for every 5ºС, it is necessary to add 4 centimeters insulation.
Chipboard: his distinctive characteristics
Chipboard is manufactured based on wood sawdust. This material allows you to warm the draft floor immediately, without prior preparation. First of all, it is necessary to carefully align primer, and for waterproofing, then you need to lay a film from polyethylene.
After that, the chipboard placed directly on the polyethylene film. Thus, the chipboard will serve as a heater and final coating. The material can be attached to the base with anchors expanding dowels and other methods.
The chipboard is not allowed to be used as a final coating in places with high humidity - cellars, garages because of its inhaustibility. Since high loads will not be provided on the floors of the cellar, the chipboard can be glued to concrete by means of a molten bitumen or construction glue. By making a double insulating layer, you will increase the temperature in the basement, and prevent the occurrence of dampness.
Warming with sawdust walls
In order to insulate the walls and partitions with sawdust, you need to prepare the mixture on the following recipe:
Dry clean sawdusts are mixed with lime in a certain proportion: sawdust - 10 parts, lime - 1 part, or with a gypsum in a proportion of 8 K 1. The resulting mixture is slightly moistened with antiseptic solution (25 grams per 1 bucket of water), fall asleep into the walls of the house, And then - compact. After such treatment, a layer of wood sawdust will not be seized, and the antiseptic eliminates the likelihood of the appearance of pests.
Wood blocks can be easily obtained independently. For this material, sawdust, cement and copper sulphate are used. The sawmills are uniformly wetted with a solution of copper mosquito, then mixed with cement in the following proportion: 10 parts of sawdust to 1 part of cement. This is enough that the wood chips be covered with a uniform cement layer. Waters need to take so much that the lump of the cooked mixture immediately disintegrated. Feeling the mixture should be a bit wet, but the water from it should not be squeezed.
The resulting mixture is falling asleep on a layer of waterproofing into the walls in the walls and in the interlated overlap of the house. The mixture is thoroughly tamped after each backfill, since its shrinkage depends on the quality and density of the tummy of the material. Due to the fact that sawdust keep moisture, and they are stacked by wet, cement immediately begins to collapse, forming a wooden block. After complete drying, a durable solid layer is obtained - it almost does not seek under his feet, but only crusts. Thus, as a result of the technological chain, material with excellent heat and sound insulation qualities is obtained.
Warming sawdust ceiling
To the issue of thermal insulation should be approached very responsibly, because through the ceiling takes about 20% of all heat in the room. The insulation of the ceiling with sawdust is much cheaper than other insulation options.
How to warm the ceiling with sawdust:
Work begins with the fact that the draft ceiling is covered with a pergamine. Ceiling boards are processed by flame painting. Here it is best formed by sawdust, stored from 1 year and more, otherwise cement may not be captured. At the same time, sawdust should be nemocular and odorless mold.
Speakers are kneaded in a water-cement solution in a ratio of 10 to 1. Waters need to take so much so that the mixture is slightly humid. 1.5 water buckets takes on 10 width buckets. Wood sawdust stirred with dry cement with gradual addition of water. As a result, the chips should slightly move into cement.
The prepared mixture is scattered and tamped between beams over the surface of the overlap of a 2-centimeter layer. It is best to perform work in the summer so that everything is dried by autumn. A fully dried mixture under his feet is not presented, but only a little bit of crust.
The sawdust fractions are different. The smaller the sawdust, the more you need to take water, for wetting. Accordingly, the amount of cement will also have to increase. When the sawdust fresh - cement is required. However, the greater the mixture of cement, the lower the thermal insulation properties of the material.
Thus, wood sawdust can be successfully used in creating a good warming layer during the construction of cottages, country houses, as well as various business buildings. During insulation with sawdust, a number of specific nuances should be taken into account. However, producing insulation according to all the rules and technological requirements, you as a result get a dry and warm room for many years.
Warming sawdust
Currently, the insulation of the floor by sawdust is very popular. This is a completely affordable material with good thermal insulation characteristics. However, so that the insulation of the floor is as successful as possible and qualitative, you must first of all choose suitable sawdust. Perfect option - It yourself goes to the forest, to nourish enough firewood there, make sawdust and with their help to warm the floor. Sawdles are necessarily processed by varnish. Its smell will scare insects and other pests. Before insulationing the floor, the layers need to be given to dry. If they are not sucked enough, then after a short time, such a insulation will start rotting. While sawdust will dry, you can prepare the floor to the upcoming heat insulation.
Sawdust, thanks to their availability and good thermal insulation characteristics, are very popular as insulation.
Before you proceed to the insulation of the floor of your house with sawdust, decide on the following important moments:
The graph of thermal conductivity described.
After you figure it out with these parameters, it will be much easier to decide on the procedure for insulation of the floor with sawdust. The technology of such thermal insulation is very simple, you can cope with it, not even having experience. Warming consists of a layer of thermal insulation material, vapor insulation and flooring. Work is performed in such a sequence:
Floor insulation scheme in a wooden house.
It is very important to select the correct sawdust, which will ensure the most efficient heat insulation. Small sawdust possess the best characteristics. Such material is formed when sawing wood. However, their weight is much smaller than the weight of large chips. In addition, a lot of dust remains in the sawing process.
It is best to use for insulation of floor sawdust of joinery production. Such material is characterized by very low humidity, because It is formed when processing already dried wood. Such sawdust in the smallest degree are susceptible to rotting and damage to beetles.
Wood blocks can be used for floor insulation. They are made from cement, copper mood and sawdust actually. This material is characterized by high efficiency, but it is usually used for insulation in houses under construction, and not in ready-made buildings.
Papers or granules are widely used. Such granulated material is obtained from a mixture of sawdust with carboxymethyl cellulose glue and the antipiren-antiseptic. Thanks to these components, the insulation has very high thermal insulation properties, practically does not support combustion and does not rot.
Floor insulation option.
Another widespread option is an opilk concrete. It turns out by mixing sawdust (usually coniferous), cement, water and sand. The thermal conductivity of this material is comparable to the thermal conductivity of the slag concrete. Due to the fact that the insulation contains sawdust, it will be necessary to ensure its waterproofing on both sides.
Also, arbolit can be used for floor insulation. This material is obtained by mixing sawdust with cement and various organic additives. From the arbolita, plates are made with high indicators of sound and thermal insulation. The material does not support burning. It is very easy to process and is characterized by high bending strength. The main disadvantage of Arbolit is that he poorly transfers the impact of moisture.
All listed materials are used for floor insulation. However, the most common and preferred option is to use sawdust in its pure form.
Ordinary sawdust, obtained as a result of sawing logs, you need to handle the antiseptic and let go well. It is necessary to know that sawdust is an excellent environment for habitat of different rodents and other pests. Therefore, the material is usually mixed with greased lime, clay, plaster, etc.
It is very important to eliminate the sweeping of the insulation. If this is not done, after a while the insulation layer may begin to settle, and the insulation will begin to pass heat.
Wood-coating sawdust insulation scheme.
To change the bulk structure of sawdust on solid, they again mixed with plaster and lime. Such processing eliminates the need to dry the sawdust before insulating the floor.
It is important to take into account that the gypsum is harden enough, so a mixture for insulation needs to be prepared in small portions. Instead of lime, you can use limestone dough, but it will be needed about 2 times more. Gypsum is often replaced by cement.
Prepare tools and materials that will help you complete floor insulation:
The most efficient, simple and widespread method of insulation of the floor sawdust is thermal insulation by lagas. This technology is especially well suited for insulation of those floors that are located near the ground (basement and first floors).
The finished mixture needs to be placed relatively small layers. The specific thickness is determined in accordance with climatic conditions. In regions with a temperate climate, there is usually a layer of insulation thickness of about 20-25 cm. If the house is not used for permanent residence, then the layer thickness can be reduced.
Floor insulation on lags is performed in the following order. First, wooden lags are installed on the foundation or log house. They must be installed by the T-shaped slab with about the same step from 60 to 100 cm. After that, the base is fixed for the insulation in the form of boards or shields. They are fixed on cranial bars or are lowered from below.
Next, the prepared flooring needs to be laid insulation. A layer of waterproofing is placed on top of it, and then vapor insulation material. The sheets of vapor barrier material must be laid on 10-15 cm. The edges of the film are bended to the height of about 10 cm. The most common and budget variant of vaporizolation is an ordinary polyethylene film. Finally, installing the floorboards on the floor and the selected finish coating.
On the first floors of the house, the insulation of the floor can be performed on lags laid on the columns of the brick. At the same time, the lags are installed on such columns onto a wooden gasket. Owls are stacked between lags and closed with a layer of vapor insulating material.
One of the advantages of the insulation of the floor sawdust on lags is the simplicity and speed of work. With such thermal insulation, almost any person can cope with such a thermal insulation, even if he never previously had to do this. This method is characterized by high efficiency. The insulation will not experience mechanical loads, which significantly increases its life.
So that the insulation was more reliable and high-quality, sawdust needs to be mixed with lime and plaster. The procedure for insulation is practically no different from those discussed earlier. The main thing is to correctly determine the required amount of gypsum and lime. Scrupulous calculations here will not be needed. It is more convenient to count in buckets: 10 buckets of sawdust need to take 1 lime bucket and 1 gypsum bucket (can be replaced by cement).
Future heat insulation should be sprayed with an antiseptic agent. 5-10 liters of water is added to the mixture. Before use, be sure to check the humidity of the mixture. To do this, squeeze it in a lump. If the lump does not crumble, then the insulation is ready for use.
The resulting mixture you need to fill all the sections that need to heat. The mixture is thoroughly tamped. After that, it needs to be left for a while she "dose". After about 2 weeks, check the thermal insulation for voids. In case of detection, the process will need to repeat.
Thus, in the insulation of the floor sawdust there is nothing complicated. Follow the instructions, and you will create high-quality and efficient thermal insulation with minimal cash costs. Good job!
Heat float sawdust with their own hands: Step-by-step instructions (video)
During the treatment of wood, sawdust are formed, but they should not be thrown out, as it is good and inexpensive insulation. They can be used to insulate the ceiling, walls, floor and other surfaces.
The main advantages of sawdust is that they are inexpensive, have high thermal insulation properties and all work on their laying can be performed with their own hands.
Despite the fact that various types are used to build walls and create a ceiling construction Materials, Find more economical insulation than this one can hardly succeed. It is sawdust, chips and slag that most favorable insulation and they can be used to insulate any structure.
Some people are skeptical about such a heater as sawdust, but they are wrong, since wood has high heat and sound insulation, and the fact that it is an environmentally friendly and cheap insulation, no one will deny. Sawdust as a heater can be used for insulation as a wooden or frame house and any other building.
They can be used not only for insulation of walls, but also for ceiling insulation, floor. Sawdust is a cheap way of insulation of walls and ceiling and all work can be performed with your own hands. If your house has an area of \u200b\u200babout 150 square meters, then the difference, if you insulate it with basalt cotton wool and sawdust, there will be about 70,000 rubles, and these are a rather big money.
Supplemes that other materials can be used for insulation of walls, for example, Pleeplex, it is described in detail in this review publication.
Do not understand literally that when carrying out insulation of walls, a ceiling or sex with your own hands, a pure chips are used. In order to insulate the house, it is necessary to prepare the mixture, which has the following composition:
Through the sawdust layer, it is impossible to carry out wiring and gas pipesAnd also cannot be used materials that block pairs.
Another advantage of insulation sawdust with lime is that they can easily fall asleep inaccessible placesthat it does not always work if you use another insulation.
The disadvantages of sawdust is that they are flammable and rodents are multiplied with them, but this is when you are insulated with sawdust in pure form. If the chips are mixed with lime, cement and moisturize with a special solution, then the described disadvantages disappear, and such a material can be used to insulate the walls, ceiling or floor in a frame house or other cottage type.
To perform work, you will need your own hands:
Depending on the locality where work will be carried out, the thickness of the layer of such a insulation may be different. For the insulation of the walls there will be a 15-20 cm layer, and for the ceiling 25-30 cm, if the climate is cold, then these indicators can be increased.
The places where the electrical wiring gas pipes or chimney will be carried out, it is necessary to see fire-bearing materials. For wiring, you can use a metal torch with a wall thickness of 3 mm. In non-combustible materials are also trimmed by places where switches and sockets will be installed.
Specialists carry out vapor barrier when insulation sawdust with lime and cement are not recommended, as there are cement in the composition, and it absorbs excess moisture. In order to check the quality of the finished mixture, you need to take it in your hand and squeeze into a lump.
He should not crumble, but from it and should not flow water. Warming with sawdust is carried out in layers and each layer must be good to rub. It is necessary to wait a few weeks, during this time the mixture can settle, and it will be necessary to glue it.
The ripening of blocks occurs for 2 weeks, at this time it is necessary to regularly ventilate the room.
If mixing chips with clay, cement, newspaper paper and water, then such a mixture can be shuffled with your own walls or a seat ceiling. If such a mixture is covered in special forms, then you can get sheets and use them as thermal insulation material.
We note that today Penofol is often used in internal insulating work, we advise you to get acquainted with the characteristics of the foam, as well as its advantages and disadvantages.
Works on the insulation of ceilings
This part of the house should be insulated especially carefully, since about 20% of all heat takes place through the ceiling. To insulate the ceiling with sawdust, first covers it with a pergamine, before it needs to handle the beams.
After you prepare a mixture of sawdust, lime and cement, it is poured over the surface of the roof and tamper. It is better to do it in the summer so that the mixture dried faster. After the mixture is dry, it does not bend under the weight of a person, only its crunch is possible.
The amount of water that is used to prepare the mixture will depend on the fraction of sawdust than they are less, the more water it is necessary. For fresh sawdust, you need to take more cement, but it will negatively affect the thermal insulation properties of the material obtained.
Features for floors
The use of sawdust in pure form for insulation of the floor is rarely used. For these purposes, it is better to use modern materials based on sawdust.
To carry out the insulation of the floor with sawdust, the mixture should be filled with a thickness of 15 cm with frosts up to -20 degrees. If the temperature in your area is reduced by 5 degrees, then the layer of sawdust must be increased by 4 cm.
For sex, the material is used, which is made of sawdust, this is a chipboard plate. Usually they are used for black floor covering, while no preparatory work is performed.
The soil is smoothed and covered with the film, which will serve as waterproofing, after that they laid the plates, you can use a dowel, anchor or other methods to fasten them. This material cannot be used as a final coating, if an increased moisture is indoors.
Application for partitions
First, a mixture is preparing from sawdust, and then it falls asleep in the walls of the house and trambed well.
Since the mixture is laid wet, cement begins to immediately seize and thus the wooden block is obtained, which has high warmth and sound insulation qualities.
Wall circuit for insulation
The wall of the skeleton house, in which sawdust as a heater will have such a design, starting from the inside of the building:
The so-called glindobetone has good thermal insulation qualities. It turns out by mixing sawdust with clay, lime, cement or plaster and water.
In order to make 1 Cube of Glinobeton you will need 200 kilograms of sawdust, 30 kilograms of cement, 70 kilograms of lime, 300 kilograms of clay and 350 liters of water. With this ratio of all components with clay, the mass of the finished mixture will be about 550-600 kg / m3.
After swelling, everything is enveloped by clay, and after drying, the chips are firmly associated and preserved, so it is not subjected to rotting and it turns out a durable, reliable and inexpensive material. First, it is well mixed with sawdust, lime and cement and only after that everything can be mixed with clay. Seal such a mixture is not so carefully as concrete. The less it is compacted, the higher its heat and sound insulation qualities will be, but less strength.
Many people relate to this insulation with caution, often guided by no foundations with prejudices and speculation.
Speaking about the cheapness of such a material, it is necessary to take into account the fact that some organizations can give them in a gift or for a symbolic price, but we must take into account the cost of transportation.
In addition, you will have to spend money for the purchase of lime, cement and quite a lot of physical effort, but it is still cheaper than using other insulation.
When this type of insulation is selected, it is necessary to weigh all its advantages and disadvantages and only after that you can decide, suitable in your case waving sawdust or you need to do another choice.
Does the type of wood, from which we use sawdust for insulation? And how much time is approximately occupied by such insulation (area of \u200b\u200babout 50 sq.m.)?
We use sawdust as a ceiling insulation, walls and floor
From the author: Hello, dear reader! If you are interested in the topic of ceiling insulation, then you probably have already heard from all sorts of insulation. Yes, the modern market offers a great many building materials, as they say, for every taste and color. But, as a rule, modern insulation cost a lot. But the insulation of the ceiling sawdresses is quite another thing! This is an affordable, environmentally friendly material, which, in essence, is not inferior to its counterparts.
Today, just talk, is it possible to insulate the ceiling and / or the floor with sawdust. In any area repair work There are nuances that you need to know to achieve the desired result. And if we are talking about non-standard, specific building materials, the more work you need to perform with knowledge of the case. In general, read the content of this article - and you will succeed.
Let's say straight, work with wood waste - not very comfortable. I had to face "professional" insulation and with "amators", like sawdust. And, on the basis of experience, I can say that, for example, with polystyrene fiber work much more pleasant and easier.
But from sawdust I will not dissuade you in any way. This is rather a warning. And so the waste of the woodworking industry has many advantages. Among them, select the following:
You will probably be surprised, but even the waste of the woodworking industry has varieties.
For example, wood chips, which we have already mentioned Casual. It differs from standard sawdust in that it is thrown into it to obtain wood, or it is placed. Such waste is larger than just sawdust, which are more like dust in their structure. On average, the length of the chips is 4 cm.
In turn, sawdust is also different: very small - from a few millimeters, up to several centimeters in length. The size depends on what kind of processing was previously subjected to a tree.
Among other things, the difference lies in the tree species. As a rule, these are solid species, such as ash, spruce or pine, as they are widely used in joinery.
How correctly insulate your ceiling? If we compare small and large wood waste, it is preferable, of course, small. But in its mass their density will be higher than that of large, it became, such a thermal layer will have a greater weight.
Again, choose waste from carpentry production, because for these purposes the tree is pre-dried. With that, it is not easy to dry out open-air, in the rays of the star by the Sun, and forcibly, with extreme temperatures, with the use of special equipment.
Therefore, such waste woodworking industry will be unbearable for different insects, and the likelihood that the mold will be charged to a minimum. If, of course, the material will not wet before laying, say, in the rain.
Those waste, which turned out as a result of cutting logs - more wet. They are just needed to dry. It will be great if they lay under the sun during the summer. Naturally, in the process they must be pulled out periodically. Neither take care of the rain by itself.
We dealt with the types of material. Now let's talk about what will be required to us in order to start work.
For convenience, imagine everything you need as a list:
Now you can proceed to active actions.
Now we will look at the stages of work with details and nuances that you need to know to achieve the desired result. And we begin, of course, from the preparatory stage.
Warming in a wooden private house sawdust implies pre-protecting wooden structures. Even if during the construction of the house all these measures were observed, the prevention will never be superfluous. So, proceed to processing:
Another an important nuance. In detail inspect the entire design. If somewhere detect the rotten section of the board, it must be replaced. This should not save. And now that: from the side it may not be noticeable that the board / log has a rotten plot. Therefore, take a seal with a long edge and pushing the carrying structures along the entire length. Thus, you can identify rotten areas that should be replaced. It may even be necessary to replace the entire board / logs.
Now clean the boards from dust and small garbage, then bed cardboard. If he is thin, then put it in several layers of the pectorist 15-30 cm - the sawdust should not be seamless between the seams. If you put the substrate from the cardboard to one layer, the joints are punctured by a painting ribbon / scotch - anything, if only fixed.
Then lock the sheets of the substrate stapler. Watch that all layers are captured if, actually, the cardboard was laid in several layers. Edges that come into contact with carriage structures (beams) - also fixed with brackets. Then go around the perimeter of the mounting foam.
Now you can start frighting the insulation itself. For this, there are no many nor, two ways: with the use of cement and without it. Consider both.
So, dry way of frustration:
If you have a large and small waste of the woodworking industry - wonderful! Fall asleep insulation in two layers: the first should consist of larger, second - from small elements.
Large wood waste poured a layer, 10-15 cm thick, then sink as it should. Then pour the same in the thickness of the layer of small sawdust, after which I will confuse it.
20-30 cm of the insulation layer will be quite enough. Place the slag / ash on top. Naturally, the ash should be completely burned and cooled, serve it "with heat, with heat" to the roof - prohibited for obvious reasons.
In addition to ash / slag, sand / clay will be suitable. In addition, it will help to maintain heat, this layer will prevent the fat breeding of the fauna represented by insects, rodents and an ubiquitous mold. Yes, an antiseptic is, of course, it's good, but as one of my constructive comrade used to say, "it's better to overdue than to bother" ©.
Now let's talk about the second method, which involves the use of cement:
We remember that for work it is necessary to use only dry, departed materials that are not the habitat of fungal colonies. When preparing a solution, we observe the following proportions: chips / water / cement \u003d 20/3/2. "Cooking recipe" is extremely simple: mixing wood waste with cement, gradually add water and continue to mix to "complete readiness". In addition, the solution is to add a portion of lime and copper mood.
Now we supply the solution to the top and pour / pour it between the supporting structures directly on the substrate. Naturally, it needs to be dissolved and, if possible, tamper. The insulation layer at the same time will be no longer 20-30 cm, but only 5-10 cm, but this is more than enough.
After the solution is completely "grabbing," will freeze, it will be possible to move away from it. Sometimes a characteristic crunch can sound under the legs, but it is only a small side effect.
Now you can lower the boards, OSB or other solid material, in other words, mount the floor of the attic. But if you do not plan to arrange at the top billiard room, a rest room or just a storage room for what you do not need, but it is a pity to throw away, then you can not construct the floor surface. Although, the use of a attic as an additional residential space is in recent times increasingly and more often practiced in private homes.
Here, in essence, all the necessary knowledge that you need to possess the owner of a private house, which decided to insulate the roof. Now you know how to insulate your dacha or house sawdust. Perhaps the only drawback of this method of insulation is a flammability of the material, so always follow the requirements fire safety - So you save your property, and your life.
If we talk about security requirements more specifically, this means about the following:
Here, in principle, all that concerns safety. Not difficult, right?
How to perform ceiling warming sawdust in a private wooden house
Sawdust is waste production, small shake material. Such raw materials were used in construction in the era of antiquity: an inexpensive and accessible option was actively used to insulate buildings. Despite the popularity of many modern samples, wood waste perfectly retain heat of wall and ceiling floors, gender, roofs and actively apply now. Their wonderful insulating properties are disclosed in the process of a clear observance of the main stages of installation. Wall insulation sawdust allows you to create the most convenient conditions for living.
Sawdust as well maintaining heat material has a number of benefits:
However, there are disadvantages:
Warming of walls with wood chips implies mandatory material preparation. It develops from the processing of raw materials by antiseptics and its subsequent drying. To do this, you can use copper vitriol or boric acid.
Works on thermal insulation sawdust involve training essential materials and devices:
Back to the category
To determine the sizes of the insulator, it is required to find out the temperature indicators of the region and the role of a built building. So, if the structure is calculated for a short stay, the layer must match 25 cm, permanent accommodation requires an increase in these indicators up to 30 cm. A racks that create free place To fill with a bulk mixture.
Important! The points of the location of the electrical wires and chimneys are enhanced by special devices that impede the ignition of sawdust. In order to insulate the heating layout, sockets and switches, non-combustible samples of raw materials are used.
There is no need to lay a vapor insulation layer: the cement that is part of the complex absorbs the unnecessary moisture, and the unit used becomes a special fortress. For insulation, fresh sawdusts are not used due to the content of special components in them that prevent high-quality adhesion with cement layer. For this reason, the chosen raw material must be seen within 2 months.
Back to the category
Often, clay and sawdust in the solution are often used to preserve heat in the room. Such work is quite time-consuming, painstaking and requires a significant attachment of forces. Such events are desirable to spend in a warm period, so the prepared composition will be able to harden and dry quickly. Sometimes a similar solution is prepared in the following way: clay is bred by water and freeze to spring, after the designated period, it is stirred with chips.
The ceiling and the floor are isolated the same ways. First, the formwork is installed on the surface, then parchment fastened with brackets or scotch. Under it can be placed in a cardboard layer. After that, the clay with sawdust is laid out and smoothes over the entire plane, evenly filling out all emptiness. The optimal thickness of such a layer corresponds to 25-30 cm. For 2 weeks, the base fits. As soon as the material closes with the surface, the formwork can be disassembled.
Clay and sawdust use for insulation of walls in the form of plates made with their own hands.
First, the molds are made from the tree, after that they are laid out on the paneur.
For the preparation of mass in equal amounts, 2 shares of the substance are taken, the finished matrices are filled with a mixture, the upper part of the composition is resurrected by a spatula. The solution should dry, after which the finished samples are put on the walls and fixed with a wooden crate.
Such a heat insulating substance allows you to warm any room, saving your own funds.

Wall insulation with wood chips refer to the most difficult events. Here it is necessary to build a frame, fill it with a dry mixture and tamper by hand. Frame overlaps require the use of large fractions. Dry laying involves thorough drying of raw materials.
The surface treatment of the walls begins with the preparation of the insulation mixture. For this, the chips, lime, plaster or cement and antiseptic takes. The solution is thoroughly stirred and laid out in the finished frame base. It is possible to determine the degree of its readiness by compressing the mixture in the lump. If it does not scatter and does not release water, then the composition can be used. A to avoid subsequent seraging will help a thorough ending of the composition. Cement and gypsum make the composition very durable, pulling out extra moisture out of it.

The insulation of surfaces with wood chips is associated with the risk of damage to the coating with rodents, the appearance of fungi and bacteria. Avoiding similar unpleasant consequences will help add to a solution of 5-10% dry lime powder.
Wood buildings insulated with chips require increased attention in the field of fire danger. Chimneys chimnery and wires are separated, wiring hides in metal boxes, sockets and switches are isolated by safe materials.
Warming of walls with chips does not bind to significant material costs. They are practically nothing worthwhile, wood waste can be obtained completely free: ask for familiar repairs or take on the sawmill, cardboard can be stock in any store. With such waste, usually easily part.
If over time the selected raw material will give a shrinkage, you should post an additional layer.
It is not recommended to use fresh sawdust in the work: they do not contain the necessary substances and prevent the good clutch of cement with water. Consequently, the prepared composition will be deprived of the necessary properties. The best insulation variant will be raw materials departed within 2-3 months. If it is impossible to expect the designated period, you can add liquid glass into the mixture.
The heat conservation indicators and the level of noise absorption in sawdust and mineral wool are approximately the same. They are characterized by the same consumption of materials, and sawdust is also absolutely no harmful effect on human health.
Some shortcomings of sawdust, such as the ability to ignite and attractiveness for mice, are easily compensated by adding special protective components to their composition. Cement, lime, plaster, boric acid and copper cunery will not like pests, besides, they do not burn.
For the insulation of the walls, it is better to take salting in the middle fraction.
The warm period will conducive to carry out thermal insulation activities: so the mixture will quickly dry, it will not multiply bacteria and fungi.
The size of the chips determines the amount of water and additional components. So, the small substrate requires a larger volume of liquid for wetting the composition. For fresh sawdust, you need more cement, and this may affect the decrease in thermal insulation properties.
Long period of operation, cheap product, simplicity of installation make chipboard one of the most sought-after samples of insulation materials.
The best variants of the sawing mixture will be the mid-component substrates. Small sawdust contain a large amount of dust, and it is very difficult to interact with such raw materials. Large samples will not provide the building due to the level of isolation. The best variants of such materials will be small wood particles that have passed the pre-drying in the chambers. Wet sawdusts should be dried in the open form.
There is a myth that the insulation must be technological. In fact, the insulation must be functional and as cheap as possible. In accordance with these requirements, such archaic material as sawdust seems more than suitable for use as insulation.
It is necessary to immediately note that as a dry backfill, the sawdust is never used. A solution of lime, clay or concrete is used, in which the sawdust serve as a filler. Such a solution is poured into the briquettes of certain sizes and thickness, after which the briquettes are already used as insulation.
The determining factor for using sawdust is the price. Near the woodworking enterprises, it is possible to get sawdust and free. Permanent disposal of waste eternal headache of this kind of firms. The problem is that the sawdust needs to be dried under sunny summer. Wet sawdusts for use will not fit. If you add the need to independently produce briquettes, it is not difficult to understand that the whole warm season will need for insulation of the house.
Nevertheless, substantial efficiency, generation experience confirming all the properties of the insulation, and the environmental friendliness of the initial materials is three factors that make sawdust with a fairly good warming material.
The only factors for separating sawdust is a method of obtaining. The fact is that when sawing wood it turns out fine-flowing wood dust, which is called a pipe. In other cases, the chips are obtained. For insulation, the chips fit better, as wood canals remain in it, which contribute to an increase in para mmim and heat insulating properties.
If we talk about wood dust, it quickly comes up, extremely hygroscopic and is susceptible to rotting. It is difficult to impregnate with protective compositions. Therefore, when they talk about the insulation of the house sawdust, mean insulation with chips.
Separate attention should be paid to the variety of wood. Best of all, oak and aspen fits for insulation. The worst option is pine. Sawdust of this tree have greater hygroscopicity and distinguish the resin into the surrounding space, which poorly affects the insulation.
Let's talk about the advantages and disadvantages of sawdust as a heater. Dignity for the most part Missed and logical:
With disadvantages a little more complicated, so we will analyze every item in details:
In general, at the moment, at the moment, almost all disadvantages other than the complexity are completely eliminated by modern means. Therefore, if the extra work does not scare, and the owner of the house has free time, then the insulation of sawdust will save an excellent option and meet the winter in a warmed house.
All methods of insulation can be divided into:
Failure is extremely rare. To date, it is advisable to use the backup only for the attic overlap. To some extent, this approach can replace the ceiling insulation. The dry material is mixed with tobacco or broken glass, after which the layers fall asleep with layers of 10 cm. It is desirable to change the pattern of sawdust in layers from a small one.
Before falling down, all the slots are necessarily close to the mounting foam, the overlap itself is covered with vapor barrier. Be sure to take care of the protection of the wiring and the chimney so that the saws do not light up from high temperatures or the stenched spark. After frowning, the sawdust is closed by boards. Between the boards required ventilation gap.
If you use a filling as insulation, then you need to be ready to glue the material in 2-3 years. What kind of fractions there is no chips, it is in any case poured.
Pouring implies the use of a solution with a filler from sawdust. The solution is poured into the cavity of the walls or the ceiling. But for the walls it is easier to use briquettes. These are blocks convenient for insulation of dimensions, which are placed in the wall as an internal insulation. For outdoor insulation, apply sawdust insulation is not recommended, since the tree in any case will pull moisture, which will lead to corrosion and rotting.
As binders are used:
It should be noted that the lime is not used without cement. Lime powder is added as a additive to save the cement composition. Before considering the use of each of the binders, it should be noted that there are two ways to process sawdust before insulation. In the first case, the sawdust is soaked before applying. To do this, you need to spray an antiseptic and other impregnations over the middle layer of sawdust. The problem is that the sawdust will dry for a long time, this process should occur with natural ventilation in summer, indoors. Wash with such impregnation of sawdust will be the whole season. This means that insulation will have to be transferred to the next year.
There is a way to speed up the process. To do this, impregnates add to water, which is used to prepare a solution. An antiseptic can be added and at all at the stage of preparation of the solution. As an antiseptic, you can use a copper vigor or a boor. But it should be borne in mind that when heated, these substances may highlight substances harmful to the human body. Therefore, for baths such additives will not fit.
For the preparation of the cement-based solution, you will need:
It is advisable to make a solution manually. In the concrete mixer, the sawdust can be collected, which will spoil the material. After mixing all parts, the sawdust must be smeared in solution. To check the preparedness of the mixture, it is compressed in a fist. The finished solution is allowed moisture, but they will not flick drops along the fist. This means that you can start the fill. Lyut ophink concrete with a single layer, with a slight seal. This mixture is suitable for sex, because it can be walking, without fear for the integrity of the coating.
For the walls and the attic use a solution based on lime. It includes:
Water is poured at the rate of water required for breeding construction gypsum. The advantage of the lime solution is the economy of cement and antiseptic. In the thickness of the limestrine, not a single rodent will crawl. But at the same time, the lime makes the material softer. Because of this, this solution is not suitable for floor insulation. Otherwise, the floor will have to be stuck with wooden stoves and all the time fear that excessive furniture will sell a black floor covering.
The third option of the binder is clay. Clay is needed fat, only such a binder characteristics are sufficient to use sawdust. To the touch piece of clay will be about as soap. It should be noted the need for soaking clay before creating a solution. Clay should fly around the day in water. If you take into account the large amounts of work, it is better to prepare a more finished mixture of the future.
Clay is poured with water in relation to 5 parts of clay on 2 parts of water. After swelling, clay is mixed with sawdust. Sawdles It is advisable to mix with a lime powder in respect of 10 K 1. The solution is placed in plates 25 by 25 cm. Approximate layer thickness 10 cm.
It dries a draft coating for about a month. After that, a solution based on fine-flow chips or wood dust is prepared and a numeric coating is performed. Cover coating It can be covered with cracks, it means that too small thickness of the second layer was selected. Cracks are enough to smell the same composition. According to the resulting floor, you can walk with your feet without fears, arrange furniture and cover all sorts of coatings. The biggest drawback of clay: time.
The composition of the insulation will not be changed strongly, but different compositions will be better suitable for different coatings. Therefore, we will discuss optimal option For each surface.
Walls are distinguished by increased attention of rodents and pests. At the same time, the requirements of increased resistance to mechanical exposure are not subject to the walls. Therefore, as a heater, you can use stucco or lime-based briquettes.
Of course, you can use the casting method. So the house will be insulated more reliably, but the effectiveness will increase not much, and the complexity will increase significantly.
For the floor of the first floor it is best to use a concrete or clay solution. The choice depends on the disposable time and the desire to work. The clay solution is harder and more durable. The opilk concrete is easier to make and fill up faster.
It is not a ceiling, but an attic overlap with the fake of an attic floor sawing or a mixture of sawdust and lime. Many dackets advise mixing sawdust with tobacco or broken steering to prevent the appearance of rodents. Why do not all use lime?
When heated, the lime powder can start highlight heat in large quantities. Together with free lying sawdresses, this can lead to fire.
In the roof too large requirements for the absence of hygroscopicity and resistance to moisture. Therefore, for insulation of the roof, the sawdust is not used. There are many sufficiently cheap materials that are easier and more reliable to install on the roof instead of sawdust briquettes.
In fact, the determining criterion for choosing a mixture is a disposable time. If time is, it is better to warm up with a clay solution. If with time problems, then in the residential part of the room it is better to use opilk concrete, and the sex of the attic wake up a mixture of sawdust and broken glass. Otherwise, it all depends on cash. If there is no lime, and the cement must be bought, then the walls are better to insulate with a lime solution and so on.
In general, sawdust did not lose their relevance as insulation. It is cheap, environmentally friendly and quite functional. The only factor that can scare the builder is labor intensity. In order to use the sawdusts need to be processed, dried, plan the place of use of a fraction. Prepare a solution, prepare briquettes and there are still very many time-consuming and long procedures. Nevertheless, the right approach to waving sawdust will make it possible to create a warm and durable design.
Before insulationing the ceiling in a private house sawdust, you need to prepare other components of the overlap design.
Works start from the device of a draft tail ceiling:
After performing the binder, all the cracks in the design bloody the mounting foam. This will increase the degree of thermal insulation of the room and will prevent the penetration of wet air from the house inside the heat insulating layer.
To ensure the fire safety of the wooden overlap with the insulation of sawdust, all potentially dangerous elements (wiring, flue pipes, lamps) are protected by non-flammable materials.
As a result of processing and processing of boards or logs, small particles are obtained as waste. Experts share two main types of wood waste waste, distinguished by the method of manufacture and size:
It does not matter what kind of wood particles to use, each specification has identical advantages. In particular, it is possible to allocate 3 main positive qualities
Sawdust - Affordable and Environmental Material for Insulation
It can also be noted that the layer of opiled, used for the ceiling insulation, does not have a significant pressure on the structure of the structure, that is, the proportion of the substance is minimal. Of course, with the addition of additional components, such as cement or lime, the mass is becoming heavier, but insignificantly. Before switching to the insulation of the ceiling with carpentry waste, it should also be studied how to properly prepare sawdust to work.
Insulation the attic with sawdusts is used in residential and economic buildings. This material is inexpensive, affordable and natural.
The surface where the heat-insulating layer will be laid, should be prepared by saving all the cracks of the clay or blowing the mounting foam. If the chimney is located in the attic, for fire safety area around it blind or other non-flammable material.
Then the sawdust is prepared. Important moment - size, because the larger the fraction, the lower the density of the heat insulating layer. Warming the attic, it is best to use small sawdust, obtained by sawing wood.
For the preparation of the heat-insulating solution, it will be necessary: 85% sawdust, 10% of lime-fucked, 5% gypsum. Initially, sawdust is treated with antiseptic solution (for example, boric acid) and dried. Then, in the pre-prepared container, all components are thoroughly mixed. After that, the mixture is bred by water, until it obtains a non-painting, slightly wet consistency.
The resulting solution is falling asleep on the area of \u200b\u200bthe attic of the dense layer, the thickness of it is about 25 cm. It is well tumped, so that after drying it it was not too porous and did not give shrinkage. The process must be performed as quickly as possible, since the gypsum dries quickly and you can not catch it in time.
After pouring the solution from sawdust, the milk-free adhesive floor is filling from above.
Everything else, sawdust is great for insulation of the house in a wooden house. Details of thermal insulation here:
It is best formed to arrange the ceiling ceiling overlap in the private home owner of the medium size. The fact is that with small wood waste will be difficult to work, and the large-scale material does not have a sufficient degree of thermal insulation.
The optimal insulation is considered to be sawdust obtained as a result of cutting in a carpentry production, since they have a low degree of humidity, they do not need additional drying and they do not begin to rot.
If we were available to waste woodworking, which have a natural moisture, then before use they should be decomposed under a canopy and dry carefully. It should not cover the sawdust, as they will then begin to chant.
Specialists advise to give preference to waste recycling of coniferous wood. Since this material contains a lot of resinous substances, pests fear to settle in it. True, making a decision, how to insulate sawdust ceiling baths, it is better to use raw materials of deciduous trees.
Before laying this species The insulation must be searched for about a year. During this period, the level of sugars in sawdust is significantly reduced, namely, they contribute to the process of rotting
It is necessary to pay attention to the fact that there are no extraneous impurities in the insulation. It is desirable to sift sawdust, and a large garbage is removed manually.
Sawdust, like insulation, are great for floor insulation. As in the case of a ceiling, sawdust for floor insulation must be prepared from rodents, insects and microorganisms. To do this, it is better to use special finished solutions.
The difference between the insulation of the floor from the thermal insulation of the ceiling is that it is very difficult to glue the insulator, which gives shrinkage in the sexual design. Therefore, you need to choose a method in advance, in which the mass will not be dying over time. Practically, this means that it is under the heat insulation of the floor, it is worth using non-dry sawdust, but mixed with different components and further hardening.
To prepare this mixture you need to add gypsum or cement to formulates. Observe such proportions: 85% sawdust, 5% gypsum and 10% lime-puffs or lime test, which you need to take two times more than dry lime. Do not forget that the gypsum is hardening very quickly, faster cement.
Drying sawdust before kneading no sense. On the contrary, if sawdust dry, it is worth adding some water. The degree of readiness of the mixture is checked in the hands - if the lump does not scatter and does not spread, it means that the composition is ready.
If insulation is carried out in a building that has already been exploited, then the existing flooring will have to be dismantled, overlapping overlap to the antiseptic with moisture-resistant mastic, and then mount the substrate from vapor insulation material or film.
The created mixture of sawdust is mounted on the substrate and is well tilled. The thickness of the layer should be approximately 10 cm. After the death of the mass must be left to frost in about 2-3 weeks.
When using dry sawdust, you need to create a raised floor. All wooden parts must be covered with protective means. Next, on the base, the draft floor is mounted from the boards for which waterproofing is sprinkled. Speakers are embanked on top of the hydrober. The layer should be from 10 cm or more. Note that insulation sawdust is not suitable if you are going to make a screed. Owls are distinguished by low strength and give a serious shrinkage. Before mounting the finishing coating, you need to leave half 2-4 days. During these few days, there will be a shrinkage of sawdust by 2-3 cm and it will be necessary to plug an additional amount.
Be sure to keep in mind that if formilians do not make good waterproofing and ventilation (the gap between the finishing floor and the layer of insulating material), then they can lose their heat-shield qualities.
Which layer sawdust is needed for the insulation of the ceiling, depends on the composition of thermal insulation. Clean sawdusts can be used or a mixture of chips with other materials, such as lime, cement or plaster.
The sequence of laying consists of the following steps:
If the use of pure chips is not suitable for any reason, the question arises, with which to interfere with the sawdust for the ceiling insulation.
For insulation, the ceiling is suitable sawdust in combination with cement and lime. For the preparation of the insulation, take all the ingredients in such a proportion:
Sequence of preparation of the mixture:
Important! If the mixture is prepared for the insulation of a bath ceiling, then the copper sipop is not used, because when heating the insulation, it can be released in the form of harmful evaporation into the air. . The prepared solution is scattered by the attic layer with a layer with a thickness of 250 mm
It is thoroughly trambed, otherwise, after drying, he will become porous and will give a shrink.
The prepared solution is scattered over the attic overlap with a layer with a thickness of 250 mm. It is thoroughly trambed, otherwise, after drying, he will become porous and will give a shrink.
All ingredients are taken in the following proportion:
Cooking process:
If a mixture is used with the addition of gypsum, then laying and tamping is carried out as quickly as possible, since the gypsum is rapidly folded. For the same reason, the solution is prepared in small batches.
The liquid mixture is placed in several layers of a small thickness. Each layer is thoroughly aligned and trambed. Stacking continues until the top of the overlap carriage is reached.
A thin layer of ash is poured on top to protect against mold and pests. After 2-3 weeks, the liquid mass will finally dry. After that, the layer of vaporizolation is stacked. To do this, the plastic film is attached to the beams overlap with brackets.
After laying any variant of the insulation, on top of the beams, it is equipped with a draft or finishing board, depending on the purpose of the room. Also you can put on the beams metallic reinforcement grid And fill cement screed.
The process of insulation of walls by sawdust is actually quite simple and even trivial. If we are talking about the insulation of sawdues of walls, attic or sex, then here you only need to fall asleep sawdust in the ready-made design.
That is, the initial goal is to assemble the framework of the desired size. This is where some misunderstandings can begin.
The fact is that the creation of a frame must clearly respond to the size and number of insulating material.
When finishing walls with sawdusts, they can be collected in polyethylene packages
Gostas have formulas for calculating the necessary insulation layer of isolation. To do this, it is necessary to calculate the thickness of the wall, multiply to the thermal conductivity of its material, then the resulting indicator is divided into climatic conditions in your region.
As a result, you will receive a certain number. This is a nominal indicator of the thermal ability of the walls. Now you look at the norms by regions and the difference between the norm and your number are trying to level.
It is this difference that affects the selection of insulation. Rather, its quantity. Only after the calculations you can know exactly how many sawdust you need.
As a rule, for normal finishing of walls of bricks, the thickness of the insulation layer from 15 cm.
Then they start assembling the frame. There is another interesting point here. The frame must be assembled so to fill it completely. No emptiness, openings, inacted areas can not be. After all, this way, you just talk part of the surface of the walls.
The frame is collected mainly from the treated wood. If it is necessary to work with drywall, you can fix it using aluminum profiles. When finishing the attic, so act even preferable.
After all, aluminum is not accessed by rodents as a mineral wool for insulation of walls, and drywall is used almost everywhere as monster walls.
In addition to frustration sawdust in a dry form, you can also create a solution. In the people, this solution is called opium concrete.
When creating opilk concrete, they use cement, lime and directly sawdust. Sometimes also use clay.
Blocks of oprob concrete, suitable for work
The clay used our ancestors, even when the cement was strengthened only by expensive buildings. With lime, the situation is similar.
Clay can link sawdust in dry form, forming the plates of the desired dimensions. However, the clay material does not have sufficient strength. With a serious pressure, he can crumble, and insects in it settle down with a big hunt.
With cement, the situation is easier. It binds the material very high quality, forming really reliable blocks. In combination with lime, a powerful strong block is obtained with filling from sawdust and good thermal insulation properties.
It can already be laid according to the standard scheme, as they do with the same mineral wool or polystyrene foam. Before mixing the solution, it is desirable to sprinkle sawdust with boric acid or special antiseptics. Thus, you reduce the likelihood of material destruction and increase its durability.
Vladimir, 24 years old, Schochi:
He insulated the cottage sawdresses. Rather, only the walls were insulated with sawdust, the roof was still preferred to separate the mine. And what is interesting, sawdust with their task copes almost as good as Wat. And they cost me very cheap.
Peter, 36 years old, Yekaterinburg:
Friend advised to buy a sawdust truck and insulate the walls of the houses them. Like, it will be faster and cheaper. I agreed, although not without fears. Somewhere in the week completed work.
And you know, I am amazed. I never thought that sawdust could be so cool isolation. Yes, they need them more, yes, you need a good frame.
But I just counted and realized that they cost me 6 times cheaper. Is this not an indicator?
The most difficult thing can be called insulation of the walls, because it will require a framework for this. The framework needs to be filled with sawdust and tampering manually. For laying B. frame wall Luggage solids are suitable. With a dry version of the bookmark, it is worth taking care of a thorough drying of sawdust, so that there are no moisture left.
With a wet method, the mixture is prepared from wood chips, lime, plaster or cement, with the obligatory addition of antiseptics. A thoroughly mixed mass is moisturized, fall asleep in the prepared frame and the trambet tightly so that the material does not ask. Gypsum, like cement, pulls out all the existing moisture, and makes a mass of monolithic.
Between the wall and insulation, it is necessary to lay a waterproofing material having vapor-permeable qualities. It is from the quality of the tamping and the density of the laying depends on the effectiveness of the insulation and the level of shrinkage. If it is not tight, emptiness will appear, and heat loss will begin.
The mixture is layered with layers of 20-30 cm high and trambet. After that, the second same layer is poured. And so repeat the actions at all height. The thickness of the insulation depends on climatic conditions. For example, in the house of seasonal living there is enough thickness of 15 cm, but in the overhaul, you need a thickness of 25-30 cm. The frame is created from wooden boards with a cross section of 100x50 mm.
The mass is harden about after 1-2 weeks, and it is finally grasped somewhere in a month. All this time should be controlled so that the air humidity does not exceed 60-70%, and the temperature did not rise above 20-25 degrees. In addition, you need to regularly ventilate the room. After that, you can proceed to finishing work.
Houses insulated with sawdust are an excellent option. They combine high indicators of heat conservation with not high costs for work.
Speakers are formed as a result of processing wood, and at various stages technological process This secondary product is obtained different quality. First, inhomogeneous is the fractional composition of chips. With a rough woodworking, large-scale sawdust is formed, and the more delicate work, the smallest there will be a waste. For example, by contacting the workshop where they are grinding and cutting off the boards, you will find a large and coarse chips near one machine, and near the other - very pleasant to the touch, even fluffy.
This, by the way, not idle information. Preparing to insulation, you need to evaluate which product you need, because the quality of these materials in the role of the insulator will be different. So, smaller sawdusts have the best heat assistive properties, although weigh more, and they are clogged into any cracks, even where it is not necessary, as they are strongly dusty, and large are quite suitable for the draft layer, because it takes a larger volume and create an air layer.
An important criterion for assessing the applicability of sawdust in one or another sphere is their humidity. If you hit the pad of the cutting of fresh trees, then there will be a very plated chips, and everything in the same workshop on the cutting of the boards will be a good dry material, because before such treatment, the tree is dried in special furnaces forcibly. It is these sawdust and preferably to use for insulation. By the way, if you buy a filler not directly from the workshop, or you are not familiar with his prehistory, then you can estimate the moisture directly to the touch.
Take a handful of sawdust in your hand, squeeze into a fist: if they crunch and scatter, knocking down to fly through the slightest slits between your fingers, then the product is dry, and if small, but lumps are formed, then this material is not succeeded. In general, wet sawdust can also be taken, but if you have a big reserve of time, because you need to dry them all the same, if you do not want the insulation to make you quickly rotate. They will have to scatter on a spacious closed area, you can use the attic, and dry all summer, constantly stirring to the whole volume, then the likelihood of rotting will decrease, and for different bugs such wood products will cease to be interesting.
Sawders are rarely used in pure form, usually a mixture with clay, cement or lime. But if you have so conceived to doly, exclusively by wood components, you will have to treat them against fungi. Also prepare that you need a large thickness of such a warming layer, and the method of isolation is possible only over the ceiling (falling asleep between beams, for example), because the sawdust from the bottom of the sawdust will be glued to the surface.
Answer is responsible: the sawdust is not perfect at all, but just a good and cheap heat insulating material. Wood sawdust and chips possess in the role of the insulation with great advantages, but they are not deprived of the flaws.
Woodworking waste is attractive because:
However, the listed advantages cannot be fully attributed to the processing of plate-type cooker and MDF. They contain a large amount of dust complicating the performance of insulation and reduces the environmental characteristics of the insulation obtained with them.
Most recently, the required amount of sawdust could be gained in any carpentry workshop, the leadership of which even thanked for the liberation of the premises from the materials that was considered garbage. Now woodworking waste is, though inexpensive, but still a commodity, which, except individual builders, is widely demanded by smoking and sausage production. In Perm, for example, woodworking enterprises offer sawdust at a price of 10 to 20 rubles per bag.
Disadvantages of sawdust are concluded in the following moments:
To create a heat insulator using sawdust and cement, the following materials should be prepared: 10 buckets of sawdust are taken by one bucket of cement and lime. All these components should be mixed for the ideal impregnation of sawdust prepared composition, carrying out the insulation of the roof or attic. Then you should make an antiseptic in the water, pour this composition In the wage to irrigate the mixture.
Checking, taking a little composition and squeezing it in hand if the water does not appear, and the scattering of the lump does not occur, it means that the solution is correct. In the next step, make a falling of the composition with sawdust and cement with its layer-by-layer traam. Full ripening of blocks should be waited for about two weeks at least.
By ensuring the insulation of the ceiling, floor or walls with the composition of the chips, all the work is carried out in a well-wedrid room. Two weeks later, those places that were covered should be inspected, which will allow to identify the presence of voids arising from drying out. If there are emptiness, they are filled with chip composition.
As I said, insulation sawdust The method is not new, but if earlier he was hardly the only thing, now people have the opportunity to choose. Therefore, first you need to weigh everything for and against.
As usual, let's start with the advantages:
Sawdust in bags.
If you compare the insulation of the house in 150m² with basalt wool mats and homemade scattering briquettes, then the economic benefit is approaching one hundred thousand rubles, which will agree quite significantly.
Hiring people in this case is not an option, the economic benefit will be zero, it will be cheaper to buy a foam or basalt Watu. and do everything in a few days off;
Chips with a large fraction.
We now turn to what is usually silent, that is, to the disadvantages of this method of insulation
And it does not matter what will be insulated, the floor, the wall or roof of the minuses are almost everywhere.
So the eye looks like, spoiled wood.
Summing a small interim result can be stated:
Material with shallow fraction.
If you are not afraid of the above arguments, and you realized that the insulation of sawdust is quite a worthy option, I slowly go to the main issue - how to insulate the ceiling, floors, walls, inter-storey overlaps, simply speaking, the whole house yourself.
Work associated with how to insulate sawdust ceiling in private home ownership, you should start with the ceiling overlap binder, it is performed in a specific sequence:
Speakers are represented by fine wood chips isolated during wood processing. They apply not only to carry out thermal insulation works in wooden houses, but also baths and household buildings.
The insulation of the ceiling sawdust in a private house allows you to save on the purchase of expensive materials, but, at the same time, get a great result. Implementing the heat insulation, it is necessary to follow certain rules and requirements. For example, to enhance fireproof sawdust and protect them from insects, lime add to the solution. To prevent the formation of mold applies copper vigor. Also to extend the service life of the material it is impregnated with special antiseptic compositions.
Since sawdust is quickly ignited, prior to the start of installation work on insulation, all wires that come into contact with them are placed in protective corrugations, and the chimney is planted with a layer of minvati or other material sustainable inflammation.
The most common and frequently used method of thermal insulation on the ceiling - on the side of the attic or the second floor. In this case, the thickness of the insulation can reach 30 cm. On top of it laid special flooring for free movement along the attic room, or cement screed, but before, the material is covered with a grid.
Before talking about technology application, consider the quality of the source material. When buying sawdust for insulation at home, we recommend considering several features
The first thing to pay attention to is the size of sawdust. From this directly depend on their properties as insulation.
The second property of sawdust on which you need to pay attention is their humidity.
It is important that the material you will use for the insulation of the house was dry, since wet sawdust will rot, as well as attract bugs. In the workshop for processing freshly saw wood sawdust will be wet, it is better to prefer the waste of the workshop to circumcise the boards, since before this work, wood is carefully dried
In the case when the origin of sawdust is unknown, you can check them on moisture yourself: If, when compressing in a fist, they scatter and crunch, then the product is dry, and if they are collected in lumps - wet.
Wet sawdust can be dried, but this will require a place and time. You can decompose the sawdust for the summer in a dry ventilated room (for example, on), and periodically mix them.
Only with the form it seems that all the sawdust is the same. In fact, they differ significantly from each other. And for each type, their methods of preparation and laying should be applied.
Different kinds sawdust
Consider the main differences.
Distinguish two types of factions:
Small trunk is considered the best option in thermal conductivity. It forms a dense layer that does not transmit heat and slightly sediments.
But usually a mixture of both species in different proportions are used.
The suitability of sawdust for thermal insulation depends on the tree from which they turned out. For insulation, it is recommended to choose from coniferous trees - pines, spruce, larchs. The resin contained in their wood prevents rotting and scares insects and rodents.
Buck and oak sawdust are considered good. Birch waste has a low thermal conductivity. But the birch wood is easier coniferous to rot.
This is an important characteristic of the material, especially for insulation with a dry way when the backfill is carried out without the use of additional binders. In this case, humidity should not exceed 12 - 14%.
Waste of joinery production has the lowest moisture content, since dried wood is used for these works. Most sawdust obtained during sawing logs are not dry enough. Therefore, before applying, they must be additionally dried.
Given the following characteristics:
In addition to insulation, sawdust is used for the full construction of buildings. However, buildings from the opilk concrete today are rare. Nevertheless, experts assure that opilk concrete is a very promising material that allows you to build economical housing with decent operational performance.
The manufacturing technology of such material involves the addition of binding components, for example, clay, lime, liquid glass. These additives reduce shrinkage phenomena and make cheaper the cost of modules. Using the control of the proportions of individual components, relative to the total weight, the density, porosity and strength of the final product can be changed.
Practice shows that optimal protection reaches after cladding, however, for example, a bath of sawdust can be used without finishing.
The advantages of opilk concrete include:
From the shortcomings, we note:
For a house with seasonal accommodation, simply speaking, cottages, the thickness of the wall insulation is made about 150 - 200 mm. Paul, attic and inter-storey floors are insulated with a layer of 250 mm. But for a capital residential building with year-round accommodation This data should be multiplied by two.
Usually similar materials are used to arrange wooden and frame houses.
Not so important, you will fit the finished mats or fall asleep and rub the sawdust solution immediately between lags. Initially, it will be necessary to equip a layer of waterproofing
The most accessible option is at the moment this is the use of technical two-layer polyethylene.
Arrangement of a wet clay solution between lags.
The waterproofing layer should be solid, that is, to go like chernovoy semi, so rude lags. When insulation is equipped in the subfield, there must be a small ventilation gap between it and the finishing floor, about 20-30 mm. But the sawdusts of the piece are hygroscopic and access to the environment should be dosed, so the vapor insulation membrane is covered on top and it is already stuffed with a layer of finishing floor, as in the diagram.
Floor insulation scheme sawdust.
In inter-storey floors, the lower waterproofing should be mounted only directly above the wet rooms, such as kitchen or bathrooms. Over the rest of residential rooms, top and bottom of the insulation layer, is enough to be able to WHOW or wax paper. The same applies to the litter in the attic.
If the attic is not planned to be done by residential, then usually the owners just fall asleep with a dry layer of sawdust with lime. But only in the case of the attic, I strongly recommend not to regret the funds for good antipyrenes.
Waterproofing with bitumen mastic.
Although dry damp gives a lot of dust and it is better to immediately pour and slightly tamper cement or clay solution. So you will be exactly sure that your insulation will not sit down. Plus, the sawdust is well soaked with protective means at the stage of kneading.
As the insulation of the walls of the pros and cons of which we have already discussed sawdust fit well. About insulation brick house I already told. A wooden or frame house is a little different. Dense waterproofing here is not used here, it is natural, because who will like to build a wooden house and, in fact, live in a cellophane package. Instead of it from the inside, parchment or some vapor barrier membrane is mounted.
From above on the framework of the house, plywood of the FSF brand or OSB sheet is thick of about 10 mm. From the inside, the lining or plywood of the FC brand is suitable. Between them, as shown in the diagram, the insulation itself is located.
If you prepared the mats in advance, they are inserted at the installation phase. It is much easier, you can gradually, slowly do and dry the right amount of mats, and then in a few days insulate the whole house.
Warming the wall of the frame house sawdust.
I saw how much strength put one of my neighbors in the country when I fell asleep and tamped a sawing insulation based on cement between the outer and inner wall sheets.
In theory, this is not difficult, but in practice, you will need to let the solution, fasten both sheets, fall asleep the solution into the cavity between them and the tamper. After that, wait a few days until they grab, put another number of outdoor and internal sheets and repeat the procedure. Believe it for a long time and hard.
Failure to the insulation with your own hands.
When the floor is insulated with bulk sawdust, if necessary, the old floor is dismantled, after which the ceiling beams are carefully processed by an antiseptic. On top of the beams, the draft floor is spilled, which is also processed by antiseptics and antipirens. Through the draft floor it is worth the "breathable" material and pour sawdust. The sawdust layer should be at least 8-10 centimeters. To further increase the antiseptic properties of the insulation, the laid scenes are slightly wrapped with a solution with a solution, after which they give several days to dry. During drying, the sawdust layer will be spent on several centimeters. On top of the dry insulation, it is pure floor.
Such a technology is used as for the insulation of floors of the first floor, so inter-storey overlaps, only with the difference that in the second case, a layer of sprinkling sawdust increases to 20-30 centimeters.
In the manufacture of a solid insulation, a mixture of all ingredients (sawdust, lime, gypsum) is initially prepared in the proportions of the aforementioned. Boric acid is added to the resulting mixture, then water is added. The necessary humidity should be such that the compressed lump of the mixture does not crumble. The mixture is distributed over the entire surface of the floor. After drying it, some areas can be corrected by adding a mixture. After complete readiness and drying the mixture, the finishing floor is sprinkled. Similarly, insulation sawdust with ceilings.
In addition to self-made mixtures, the use of chipboard or sawing granules is considered to be an less laborious way of insulation. As a rule, in this way, concrete floors are insulated.
With the help of lime and wood chips, the material of increased strength is prepared. Cement is added to these components. If you need to know how much materials it is necessary to use (their ratio, proportion), then the video will help to make a mixture properly. The main feature of this technology is to carefully stirring cement, sawdust, lime. Due to this, wood chips are in the future, it is well soaked in moisture.
Components:
Prepare an antiseptic (25 g / bucket of water) and irrigate a raped mixture. As a result, it must acquire sufficient density. You can check the preparedness of the material by composing it in the fist. If the mixture retains the form and water does not stand out, it is possible to use sawdust with cement as a heater.
From the resulting material make blocks. Failure is carried out in layers. So that the insulation is completely prosperous, you will need 2 weeks. Then the blocks are checked for emptiness. If the looseness remained, they are filled with the same mixture.
If you firmly decide to warm up with sawdust, then it's time to get acquainted with the instructions.
Whatever the composition neither to be used for insulation, clean dry sawdust or their mixture with other components, preparation is carried out anyway. If there is wooden flooded in the house, then it takes a flooring between the beams. If there is a solid base, then you must put only vapor barrier, with the edges of it need to withdraw on the side sides of the beams and knit the stapler, so the wrying of the material is eliminated. Previously visually check the basis for the presence of cracks, and if you find, close them with foam, and even then warper the film.
If there is no durable substrate, it should be done. For this, the beams are laid by boards 2-3 cm thickness, do not leave gaps between individual straps. Each place of fastenings should be provided with two self-draws (60 mm) or nails (100 mm), which are better to drive at an angle, and they should look at different directions, it turns out as if Muspist. Boards are processed against bugs, fungi and flammability. If somewhere there are slots, foam will help. And then you can retain vapor barrier.
Clean sawdust. There is an easy task here - to determine what makeup you will use as isolation, and cook it. Clean sawdust need to pour a layer to 20 cm, usually the level of beams, and not need to be dissolved. Naturally, so that they do not scatter at the first opportunity, the diffusion membrane is filling from above. If it is possible to use two fractions of sawdust, then the first layer is poured with a coarse chips (10 cm) and tamper, and then small (another 10 cm), but it is better not to be sealing it, you need to put the membrane on top.
Clay + sawdust. Clean sawdust is not the most convenient option, and only suitable for wooden floors. It is better to prepare a mixture with clay, it can be postponed not only between beams, but also on a flat concrete slab. True, lighthouses will be required to keep the level in wooden overlaps You can at least navigate the beams.
Yes, and after drying such a composition, you can walk on it, carrying out further work. For the preparation of the mixture, there are equal volumes of sawdust and clay, which first smeared, gradually adding water. When it reaches uniform viscosity without lumps and other inclusions, sawdust is added, and everything is carefully prevented. Then the resulting composition is laid out with a layer of at least 10 cm on the surface prepared by the method previously described.
Cement + sawdust. The components are taken in the ratio 1 (cement): 10 (sawdust) and are thoroughly mixed in a dry form. Then all this is sprayed with water and is brought to a homogeneous state of such a viscosity, so that the portion of the composition formed in the arm of the composition formed a sticky lump, from which water is not issued. This mixture is laid out in the same way as clay, it can also be tamped. After drying, such a insulation will be the most durable, it is almost an independent floor. But you should not make a layer too thin, he can crack.
For wet mixtures you will need to dry out, it can delay up to 4 weeks, depends on the climate and characteristics of the composition that you have turned out.
If there are cracks on the surface, do not be lazy to prepare the same solution and smear them, then all drying out again. This is although not critical, but still bring the point to the end. Next, you can go rest, as the insulation mounting itself is actually completed. But if you plan to use this surface as a floor, you will have to hide the insulation under the floorboard layer, if the house is wooden, or another flooring, if the overlaps are concrete, because clay or cement mix It is quite possible to serve as a rough screed, if it is well aligned.
So, sawdust are used to insulate houses, in particular, floors, walls and roofs. And let many vintage ways to do this have already been completely sunk in the summer due to the advent of more modern materials, they remained among them and those who were not lost today among these new products. Of course, first of all we are talking about sawdust, which today are quite widely used due to all their advantages.
Regarding any significant shortcomings, then sawdust as the insulation does not have them.
Important information! Not everyone is convenient to use bulk material for insulation - they prefer the use of slabs from sawdust. But, as they say, taste and color ... Be that as it may, and the qualities of both types of thermal insulation are about the same.
The material is a by-product of the woodworking industry. Sawdust as a heater can be used in two versions:
Smaller fractions are obtained by sawing. The result of this process is a pipe or wood dust. This material is characterized by a high filling density, it is easier to tramber. Tube parameters directly depend on the features of the working tool (saw). The chips differ in the size of the fractions - in this case they are larger (from 5 mm to 5 cm). Such material is obtained by processing a tree in several ways: drilling, planing.
Watching sawdust is carried out through chips from different breeds of wood:
The cost of material is low, which is due to the method of obtaining it. Despite this, sawdust is still often used in different purposes. The high popularity of chips is explained by a large number of positive qualities, among which are excellent indicators of heat and sound insulation. However, it is impossible to forget that this material is hygroscopic. For this reason, when the insulation of sawdust is selected, take into account the wood breed.
For example, oak fractions better than others oppose moisture. So, when contact with liquid, the material does not lose properties.
Spruce, pine and ash stronger exposed to moisture. When the chips are selected for the insulation of the object, we consider different technologies of thermal insulation:
There are other types of mixtures based on woodworking products: with clay or cement, with the addition of lime milk. Warming at home sawdust is performed using dry mixes. In this case, liquids do not apply.
Materials used for thermal insulation are constantly being improved, and all new, more modern products annually appear in the domestic market. Its cost regularly increases and not always among the owners of a private house there is enough funds for the acquisition of insulation.
For this reason, it is still popular and are relevant so-called "grandfathers", used for many years for thermal insulation of walls and roofs. The insulation of the ceiling sawdust has passed the time check for many decades, while it is difficult to say, in what condition will be, for example, polyurethane foam after a 20-year service life.
The main advantages of this method include:
At the same time, savings in the case of using sawdust as a ceiling insulation lies not only in reducing financial costs, but also in carefulness to nature, which contributes to the improvement of the environmental situation and reduce housing heating costs.
The process insulation of household consists of several stages, among which isolation of the ceiling, walls and gender. Moreover, each type of surface requires a special approach. When the thermal insulation of the ceiling surface is produced, the material intended for this can be laid as outdoor and internal method.
It is not difficult to ensure the economic benefit from the insulation of the housing with sawdust, if we compare the costs of them with the cost of popular materials and work on their installation. The heat insulation using this wood material is almost free. In addition, you can agree with a woodworking company about its delivery at a specific address for a small fee.
Of course, as when applying others thermal insulation materialsThere are advantages and cons in the insulation of the ceiling with sawdust. The disadvantages of this method include the fact that there are not all varieties of this type of woodworking waste to ensure heat resistant in the house.
Ceiling insulation by any sawing way goes on the side of the attic. Initially, the formwork is mounted from quite wide planed boards, 20-35 cm width.
Mounting to beams should be pretty durableBecause the "pillow" prepared by a wet way has a lot of weight.
Chogle needed under the slope in different directions. Suitable size Nails will be 100 mm, and screws are 50 mm.
To protect against rotting, reproduction fungus and mold, as well as to increase flame retardant performance wooden designs It is necessary to be treated with antiseptics and antipirens.
To protect the insulator From the penetration of moisture on the ceiling overlaps, the shoulder is fitted, covering the entire ceiling area, as well as the transverse beams of overlaps. Connecting seams need to be glued to a wide scotch if the PVC film or bitumen is used - in the case for runneroid.
On vaporizolation Preserved pre-prepared sawmills, any of the methods provided earlier. The thickness of the insulating layer, taking into account the building standards for the middle band of Russia, reaches 20-30 cm.
With a dry method Fixing sawdust, each layer of raw materials need to be forcibly finished and tamped, moisturized through a finely dispersed pulp. After the sediment of loose material, shove the missing layer and produce the last treatment of ashes.
After laying wet opwise insulation It is necessary to give time for complete drying and precipitation of the mixture. This time takes about 1 month in the warm season.
After this period, you can apply on top of the insulating "pillow" waterproofing layer in the form of rubberoid or film.
If the attic room is not going to use, then you can do without the construction of outdoor overlap. This has someway budget construction.
If during drying in the heat insulating "pillow" formed various crac depths, it is necessary to smell them solution of the hardener, i.e. cement mortar or liquid clay.
Thermal insulation characteristics of sawdust not inferior in quality More modern materials, such as mineral wool. To compare, you can consider the table below.
Insulation from sawdust - very good thermal insulation material. It is characterized cheap, ease of performance, naturalness and durability, so you can safely apply it in the buildings of different types and purpose.
Now let's talk about how to insulate sawdust ceiling in a wooden house. For thermal insulation of the residential building, both clean sawdust and their mixture with other materials, such as lime, plaster and cement, are used.
After laying any kind of thermal insulation from sawdust, the rough or finishing floor of the boards is laid out. If you need to perform a cement screed, the reinforcing metal grid is placed on the beams.
If you have a question that the layer of sawdust is needed for the ceiling insulation, then the thickness is directly related to the presence or absence of additional components. When using pure raw materials, the thickness of the heat-insulating layer should not be less than 20 cm.
Thermal insulation technology provides for the following stages of work:
Now let's talk about what to interfere with the sawdust for the ceiling insulation. More often, raw materials are mixed with cement and lime.
The mixture is prepared in such a proportion:
Mixture cooking technology:
Important! The mixture for insulation of the ceiling in the bath does not add copper vigorous, because during heating the substance sends toxic evaporation. . Prepared insulation stacked in the lumeges between the beams of the layer to 25 cm
The material is trambed, otherwise, after drying, he will give a shrinkage due to significant porosity.
The prepared insulation is placed in the lumens between the beams of the layer to 25 cm. The material is trambed, otherwise, after drying, he will give a shrinkage due to significant porosity.
For the preparation of this mixture use such a number of ingredients:
Cooking sequence:
If the gypsum is used instead of clay, then the solution is placed and tram quickly due to high speed Catching gypsum. It is also recommended to prepare a mixture of sawdust and gypsum in small batches.
When using a liquid mixture, layered laying technology is used. Each layer is trambed separately and aligned. The number of layers depends on the height of the ceiling beams.
From above liquid insulation Protected by a layer of chicks from pests and fungus. The final drying of the insulation occurs in 3 weeks. Now they start laying vapor barrier from a plastic film, which is attached to the beams stapler.
Once there were no mineral wool, foam and other new-fashioned materials for insulation, but our grandfathers and great-grandfathers lived in warm houses. Sawders like insulation then were the most running way to save heat in the house, and today it is also a very economical option.
The cost of modern insulation makes thinking about more economical option. Then then the thought comes on how to use banal sawdust as a heater. Living in the country village, you can get them on any panel, and there it will be willing you hard for free.
Sawdust in pure form, as they are, are used in construction quite rarely - they still need to be preprocessing, which will protect them from rot, fire and rodents. For this, the woodworking industry was mixed with cement, clay or lime. Such insulation is suitable for the roof and for walls, with their help you can do.
At home you can prepare your own hands and arbolit. Opolk concrete is a mixture of sawdust, cement, sand, lime and water. From this mixture you can make fireproof blocks that are not worse than slag blocks. However, such a heater needs to be protected from moisture. If there are floors with such blocks, it is recommended to lay a layer of rubberoid on top of it, and then it is then to carry out floor coverings. Often blocks of opilk concrete are used for the construction of utility rooms, sheds.
For its manufacture you will need (at the rate of cubic meter) 1200 kg of cement, 1500 kg of sand, 600 kg of lime and 220-250 kg of sawdust. The amount of water for the fusion of the oprob concrete is necessary, depending on the humidity of the materials, it ranges from 250 to 350 liters. We produce cheese and thoroughly mixed mass expand into prepared forms. It should be tamping the mass and intensively tapping a few minutes on the surface of the form so that all empties are filled from vibration in opilk concrete, and he asked well.
Immediately after the manufacture, the obtained blocks should not be - your required qualities (frost resistance, strength) opilk concrete will acquire in a few months, so if you have conceived the construction in the fall, prepare blocks in the spring.
Fresh opilk concrete should be sprayed in summer, and during heavy rains to strengthen the toll. Walls from blocks should be placed 4-6 months after laying. It is important to moisten the walls before plastering. In the last century, the state level was developed and approved for the use of arbolit - a mixture of cement, wood chips and chemical additives. It is much easier than opth concrete, at the industrial level is used in the form of finished plates not only as a heater, but also as a sound insulation material.
Make a similar insulation from sawdust with your own hands can everyone, but the whole process will cost much cheaper than. To do this, first prepare the material: treat the sawdust with antiseptic solution, carefully dry and place with harated lime. It is the lime to protect the insulation from rodents. There are not many lime - about 10% of the mass of sawdust. For the convenience of mixing, materials should be poured into a large container. This mixture can be used for insulation, falling asleep in the cavity of a layer of 20-30 cm.
However, it will not be superfluous to eliminate the flowability of such a heater to prevent its incentive in the future. If you decide to act in this way, it is not necessary to dry, they do not need to dry, they should be slightly moist. The mixture of sawdust and lime should also be added to the mixture, not more than 5% in terms of color ratio. This mass should be prepared by small portions, because the gypsum is grabbed very quickly, and the material is able to harden even before you prepare a place to lay the insulation. If there is no gypsum, it can replace cement in the same proportions. Gypsum and cement stretch out of sawdust unnecessary moisture.
Most often, the houses are insulated at home, due to the economy of the material and simplicity of the process. Choosing areas for insulation, we prepare a mixture of sawdust, lime and plaster (cement). For simplicity of measurements, use the same bucket, then you will succeed in 10 buckets of sawdust 1 bucket of lime and half of the cement bucket. If you want to make a solution tight, cement can be added more, but note that the more cement, the lower the thermal insulation properties of our insulation.As an antiseptic, boric acid can be used, which should be diluted in 5-10 liters of water (depending on the humidity of the materials) and pour the prepared mixture from the watering.
To check whether the mixture is ready, take a little in your hand and squeeze - if the comedom received does not scatter, our insulation is ready. The material obtained is falling asleep in areas requiring insulation. Diligently tamper the shovel mixture and leave it to stick it. After one or two weeks, check whether emptiness was not formed in our insulation, if any, eliminate them with a new portion of the mixture.
The cheapest I. practical way Heat the ceiling - it is to prepare the insulation of clay and sawdust. Such material is fire resistant, accessible is quite lightweight and easy to manufacture. The uncomplicated insulation of the roof of clay with sawdust can repeat each in the country.
Ceiling overlap must first be prepared. Since the mixture will be quite liquid, it is recommended to sing something waterproof to the ceiling boards, for example, a conventional film. It is better to attach it to the construction staple to the tree so that it does not get down. You can warm the attic and just sawdust, but in this case they should be treated with an antiseptic. Some dackets recommend adding dry tobacco leaves to layers and broken glass - so that the pests do not substantiate whole settlements on your roof. However, with such insulation, it will necessarily be necessary on top of the board or other coverage, otherwise you will not be able to exploit the attic to the fullest.
