Floor insulation thickness in a wooden house from below. Floor insulation in a wooden house from below: reduce heat loss and get rid of mold

One of the most serious accommodation problems in country house, especially if it is made of wood, is. Provide comfortable and cozy accommodation will allow insulation of sex in wooden house from the bottom that is performed using different materials and different technologies. More information about the insulation of the house from the wood and will be discussed in this article.

Drafts in combination with cool floors do not bring positive emotions, besides, they do not affect health. Therefore, it makes no sense to argue about the need for thermal insulation in the house. The insulation of the floor from below is a mandatory and inevitable event that all costs will pay off over time.

The heat insulation process can be divided into several stages:

  • dismantling outdoor coating;
  • installation of rough floor;
  • laying a layer of thermal insulation;
  • laying vaporizolation;
  • installation of the first floor.

A similar scheme is suitable for those cases when the wooden house is restored during repair. But if the house is built from scratch, then all of the above steps are performed at the construction stage.

When insulation is required from below

There are several main reasons why heat protection is performed wooden house bottom. These include:

  • the need to reduce the height of the room;
  • floor protection and all coating from freezing;
  • move the dew point, due to which it is possible to avoid the process of rotting.

During repair work In a private house, some difficulties are often arising directly related to Niza insulation. Consider the most common of them:

  • need more reliable fixation heat insulating material;
  • the presence of low underground complicates greatly;
  • the insulation of the floor below contributes to the rapid fatigue of workers, which strongly delays the process;
  • the variety of types of insulation is not very big.

Floor insulation is a rather complicated process that requires preparation. First of all, before starting repair work, it is necessary to determine the choice of insulation.

Selection of material

There are several main criteria by which the insulation should be chosen. These include:

  • resistance to rodents high humidity;
  • durability of the material;
  • mounting complexity;
  • financial opportunities of the house owner (some materials are not suiced).

Note! When insulating gender in the country house, where the owners are quite rare, it is important to choose the materials resistant to different types rodents. It is the mouse in combination with high humidity are the main causes of the destruction of wooden floors.

Table. Wood floor insulation overview.

Material name, photoDescription

It is small granules with a porous structure. Ceramzite perfectly holds heat, and small rodents and harmful insects are not found in it. The optimal thickness of the ceramisite layer is 20-30 cm.

Pretty light and easy-to-install material used for insulation of houses and apartments. Polyfoam moisture-resistant, but the rodents are afraid that quickly destroy it.

One of the cheapest insulation, which is without any problems in the nearest wood processing plant. Wood chips actively holds heat, but is not at the same illustrative.

Excellent material for insulation of houses. The slag needs waterproofing, which significantly complicates the installation process. But the slag is a durable material.

Inexpensive heat-insulating material, which not only keeps heat in the house, but also shuffling sounds. Among the disadvantages, glass gambles are worth highlighting the leaning material to the shrinkage over time.

Another type of insulation with low thermal conductivity. For mounting, eco-board requires a special installation, since manually blend it into the underground space is quite difficult.

As a breakdown insulation for the floor can also be used by expanded vermiculite. This is a natural material having a grain structure. Vermikulite is lightweight and has high heat and sound insulation properties. In addition to construction, vermiculitis is actively used in the country house.

The company is considered the leader in the market for the production of Minvati. The manufacturer has a wide selection of products.

Methods of thermal insulation

The insulation of the floor in a wooden house can be performed by two methods - on lags and a rough base. The first method is used to insulate wooden or concrete coatings. Any of the above materials can be used as a heater. The entire load is evenly distributed to the surface of the lags, so the strength and density of the material used is not important. When the floor insulation, the lags should consider the fact that the height of the room will decrease by about 10 cm due to the flooring.

The second method requires a stronger and rigid material as a heater to eliminate the probability of its precipitation under the influence of loads. The role of a rough base can perform wooden flooring, concrete screed or tightly rammed soil. Installation of the thermal insulation layer can be carried out under the floor covering. The result of the work done will depend on the correctness of the actions performed and the quality of the insulation used.

Floor insulation

Below is given step-by-step instruction Wood floor insulation using heat phol. This is a unique material made of nonstone foamed polyethylene. It has noise, moisture and thermal insulation properties.

Step 1. Expand the heater roll and gently cut it into equal parts, the length of which should correspond to the length of the house. The material is quite easy to cut down, so you can cope with it with the help of an ordinary stationery knife.

Step 2.. Treat wood used for the manufacture of various pies and lag using special impregnations. This will increase refractory, moisture resistance and, as a result, the service life of the tree.

Step 3.. Place the waterproofing layer throughout the perimeter of the concrete foundation of the building.

Step 4.. Install the strapping timber from the tree on the foundation on top of the previously laid layer of waterproofing material. The timber must be secure.

Step 5.. After fixing the bar, install special fasteners on it for subsequent fixation. wooden Lag.. Elements must be installed at a distance of 60 cm from each other.

Step 6.. Set the lags on the finished fasteners, securing them with the help of conventional screws. The levels of the strapping bar and lags must coincide.

Step 7.. Secure the special boards-supports between lags using metal corners as locking elements. Boards are needed for mounting insulation.

Step 8.. Place the previously prepared pieces of insulation across the wooden lag. The material should be based on the lateral parts of the transverse boards and on the strapping bar. Place the material across the area of \u200b\u200bthe house, tightly singing pieces of insulation among themselves.

Step 9.. Use special dowels for fixing the insulation, attaching the material to the surface of the lag.

Step 10.. Now fasten the layer of insulation along the perimeter of the strapping bar. For fixation, use screws and a special bar thick no more than 5 cm.

Step 11.. Treat insulation sheets of insulation sheets with construction fabric. This will eliminate all existing gaps through which the cold air could get into the house.

Step 12.. Perform the crate over the heat insulating layer. To do this, lock the small bars along the lag, fixing them every 50-55 cm. It is desirable to use long screws and screw them in pairs.

Step 13.. Secure the floorboard, having to have them to the surface of the bars of the previously executed crate. The next stage of work is finishing.

Step 14.. The robot on the insulation of the floor on this can be considered completed. Enjoy the results.

When choosing a heater for a country wooden house, it is necessary to rely not only on the technical indicators of a particular material. To take into account the conditions under which the selected insulation will be operated. Only so you can choose the most optimal option. But if your choice stopped at two versions, which are almost the same time and quality, one should prefer a better brand.

On a note! If the insulation was made by a well-known manufacturer, then the chances of the fact that he will serve for many years without any complaints will be much more.

Warming house from the basement

If there is a basement in a private house, it is necessary to devote the time for its insulation. This will not only avoid heat loss, but also to prevent the destruction of the house from the long exposure to dampness. To perform heat-insulating works can be used different materials, for example, foam or foaming. Many masters use mineral wool to close the overlap of the house.

Before starting repair work, it is necessary to prepare the surface, clearing it from all kinds of garbage and dust. After cleaning, it is desirable to handle the surface with an antiseptic agent, and then the primer. Such a sequence will help ensure reliable grip of the insulation with the surface, as well as protect it from the rotation process. The process of fastening the heat-insulating material cannot be called difficult, so even a newcomer can cope with such a task.

It is only necessary to apply a little adhesive to the surface of the insulation, and then press the material for a while to the ceiling. After a few seconds (the exact time is indicated on the package from glue) the insulation can be released - it is securely attached. Repeat the procedure with each of the sheets of heat-insulating material.

Heal insulation in the country house made of wood is an important event that allows you to create optimal conditions For accommodation. Only using high-quality heat-insulating material can be provided with a warm environment in the house, so it is necessary to approach its choice correctly. Fortunately, modern market It offers wide, which differ not only at the price or thermal insulation properties, but also by the installation method. Therefore, in order not to deal with trouble in the future, when choosing a insulation, you must be consulted with specialists.

Video - How to insulate a wooden floor

The wood house requires thermal insulation, especially this relates to ceiling surfaces and gender. The insulation of wooden floors, the first priority, on this depends not only the number of heating costs, but also the comfort of people living in it.

In order to start warming the floor, you need to choose a method of insulation and high-quality material. Consider what insulation will fit for this process, and how to produce high-quality and inexpensive insulation.

It is impossible to warm the flooring immediately after the construction, since the material has not yet given the shrinkage and can damage the insulation. Isolation is carried out after the structure has defended half a year

Before you buy insulation material, it is worth paying attention to the characteristics of the insulation:

  • moisture resistant;
  • fire-resistant;
  • eco-friendly;
  • with a long service life;
  • easy to install;
  • have good thermal insulation properties;
  • have a small proportion;
  • low cost.

With the insulation of wooden buildings, the most important characteristics are the service life and resistance to ignition. Consider what insulation for the floor in a wooden house can be used.

Minvata.

Highly good insulationused for thermal insulation of any buildings.

Benefits:

  • excellent fire resistance. This material does not burn, and prevents the spread of fire;
  • good indicators for thermal conductivity;
  • performs a good insulator from foreign sounds;
  • perepecility. Many builders prefer to use in the insulation of wooden structures by Minvatu - it "breathes";
  • easy to install;
  • ecologicaly clean.

Manufacturers offer two types of Minvati: in mats and rolls.

He has a very big drawback - it absorbs moisture, which reduces its insulating properties to almost zero. But this can be avoided by conducting insulation work on all rules. The ministry of private developers is used by Minvatu, due to its low cost.

Dry screed

Material with excellent gypsum-based indicators. It is necessary to conduct it after a complete shrinkage of the floor in a wooden structure.

Benefits:

  • good heat insulator;
  • does not burn;
  • easy mounted;
  • used with any finishing, outdoor materials;
  • good indicators of noise insulation;
  • no need to equip a thick layer.

There is the main drawback - the cost. Warming is expensive, since one bag of 20 kg, one square meter of the square can be insulated.

Since the material is based on plaster, it is afraid of moisture. In contrast to min cotton wool, the dry screed does not lose its insulating qualities during wetting, but the floor covering can suffer greatly.

Glasswater

This material is used to warm the surfaces for a long time, and has proven itself as a reliable and eco-friendly insulator.

Pluses of material:

  • does not burn;
  • easy to use;
  • ecologicaly clean;
  • inexpensive cost.

He has one weighty drawback - shrinkage. Glasswater decreases in sizes by 15 centimeters during the year per meter. The result becomes the integrity of the insulating layer. As well as Minvat, this material is unstable to a wet environment. When wetting, all thermal insulation properties are lost.

Styrofoam

Sostly demanded insulation among private developers. The ratio of quality and prices of this material is optimal.

Polyfoam tolerates the large differences of temperature and humidity, without losing its insulating properties. The material is capable of providing high-quality thermal insulation already with a thickness of 10 cm.

The environmental friendliness of this material is confirmed by certificates of quality, so the insulation of foam is so in demand.

The main drawback is not durable. But if you set the thermal insulating layers to equip the thermal insulation layers, then the foam will be long enough.

It is also worth noting that the coating does not pass the air and if not to produce vapor barrier, then the flooring of the floor in a wooden house may be poor quality.

Penoplex.

Many private developers ask a question: how to warm the floor by penplex, and what is the material. Superior foam possessing many advantages.

The advantages of this insulator a lot, for example:

  • does not burn;
  • not susceptible to moisture;
  • carry the temperature differences;
  • well isolates sound;
  • lasting.

Of the shortcomings, only the cost. But the insulation of floors is penplex worth it.

Ekwata.

Floor insulation EcoCite - right choice Any developer. This material consists of cellulosic fibers, boric acid with the addition of a bora. Thanks to the properties of this insulator, you can create an indisputable seamless layer. It is perfect for insulation of the floor in a wooden house below.

Ceramzit for insulation

During the construction of houses, wooden floor warming is often used with a mass of advantages:

  • low price;
  • ease of arrangement of the clamping layer;
  • environmental friendliness;
  • lie down smoothly and without seams;
  • no temperature drops;
  • ability to warm up double floors, which is a strong load.

Penophol

New foil product based on polystyrene. It is good because they can be insulated with the floor in a wooden house without opening the flooring. The process is not complicated:

Take a foam, and consolidate it from below wooden semi With the help of brackets and stapler.

It is worth remembering that the lanes of the heat-insulator must go to each other at each other by 5 cm. For complete insulation of the seams, they need to be punctured by aluminum scotch.

These are very popular and demanded insulators. Consider the better to insulate the floor in a wooden house with their own hands.

Heat insulation work - technology

How to insulate a wooden floor? Isolation is used depending on the floor mounting in a wooden house was applied. Below are the steps to the most frequently used types of insulation. To start the work, you need a floor insulation scheme, it will help accurately calculate the amount of insulator.

Warming with a small distance to underground

We'll have to completely dismantle old, wooden floors, which makes the work of time consuming. And decide how to insulate the floor in a wooden house. The principle of action is:

  • Demonstrating the plinths and flooring, before insulateting the floors in a wooden house. If in the future it is planned to apply the old finish, it is worth working with special accuracy. When laying the floor, all boards are numbered to simplify their laying.
  • Spend a revision tree from which lags are mounted before you make thermal insulation. Old and false should be replaced.
  • Each lage is attached to the reference bar from below.
  • Prepare material for wooden floor - rough. The length of the lumber segments should be less on the centimeter than the gap in which it will fit.
  • We collect a draft floor, you do not need to screw the boards to the bars.
  • Mount vaporizolation. In case the house stands on raw place, it is better to apply the waterproofing material - pergamine. The material is stacked with the wall at the wall - 15 cm, the seams are sampled by aluminum scotch.
  • To equip the lags of the first floor and put the heat insulation between them. The better to insulate the floor in a wooden house depends on the developer.
  • Mount the waterproofing material over the insulation.
  • Find the rackets of the crates 2 cm thick for ventilating insulation under the final coating.
  • Installation of floors in a wooden house, numbered boards. If old boards are in unsatisfactory condition, then they should be changed.

Ventilation for the insulated floor in a wooden house is very important, as it contributes to the insulation of the gap between the floor and insulation.

Warming the bottom of the floor with the basement

Works will be less, you can carry out insulation of the floor in a wooden house from the bottom of the basement. The procedure for performing insulation:

  • From the side of the basement must be attached to the floor vapor barrier.
  • to the sides of the beams you need to attach a small bar or aluminum profile.
  • Cut the insulation in such a way that it was 2-3 centimeters more gap between beams. Place the insulation.
  • To the previously screwed profile or bars to fasten the crate to maintain the insulating material.
  • Close the insulation and racks with vapor barrier material.
  • Close the insulation of the finish coating.

Conduct the insulation of the floor from below, much easier than to apply the remaining methods of isolation.

For this method of insulation, hard insulating material will not suit, it is better to apply eco-friendly or minvatu.

In independence, from which side you begin insulation, the order of laying of the insulating material does not change.

Double floor

This option is well suitable for rooms with high ceilings, as such a design can take up to 20 centimeters of height.

Installation Instructions:

  • Demonstration of the plinth and floor covering. If in the wooden floor there are rotten elements need to be replaced. All slots to fit.
  • Install the lags, the thickness of the heaters for the floor, must correspond to the thickness of the bars that are nourished directly on the old coating in 60 cm increments;
  • Check overlap horizon with building level. For alignment, you can apply small strips for the bar, or comb out outstanding areas with a reference.
  • It will establish a vapor insulation material with a wall at a wall for 15-20 centimeters.
  • Laying insulation on the floor.
  • Hold insulation with a film.
  • Wide a new floor.

You can insulate the floor with a clay, which is simply falling asleep on the draft wooden coating.

If the building is on screw piles, one floor insulation in a wooden house will be little. Build windpower around the perimeter of the foundation, leaving ventilation holes, To ventilate the underground.

In custody

Now you know how to warm the floor in a private house, applying various thermal insulation materials. What insulation to purchase - depends on your financial capabilities and the load, which will be found on the flooring. What warm the wooden floor, solve only you.

Send the material to you on E-mail

If during the operation of a residential wooden house, tenants feel that the floor remains cold at any time of the year and no heating saves from this phenomenon, then there is an error in the project or construction marriage. The poorly insulated floor creates problems with residents, since the energy consumption for heating increases significantly. Floor insulation in a wooden house from below should be made immediately after these unpleasant symptoms will be detected.

Works on insulation

Materials for thermal insulation

The thermal insulation is achieved in the case when the dry air layer is formed between the cold zone and warm. IN building structures This effect can be obtained using porous materials. They can be bulk, slab, rolled or produced in the form of a foam, which is polymerized in air. For insulation after completion construction work Any of them are suitable.

Mineral wool

Mineral watts include the following materials that are somewhat different by software, but on the installation technology, the scope and physical properties Very similar:

  • glasswater
  • mineral wool (basalt or made of other volcanic rocks);
  • slag wool.

All these materials have important quality - they are not combustible, destructive changes begin only when exposed to temperatures from 700 degrees and higher, while the insulation does not ignite at all. It is produced in the form of solid plates or soft rolls, which can be easily cut and stacked. When working with this requires a respirator, since the particles should not get into the lungs. For private houses, mineral wools are good and the fact that rodents and harmful insects are not breed.


Styrofoam

Floor insulation in a wooden house foam from below is considered one of the most simple ways Additional thermal insulation devices. Polyfoam plates are very cheap, and their thermal insulation properties are much higher than that mineral Wat and clay. However for wooden houses Such a heater is not safe - when opening an open flame, it instantly lights up, highlighting caustic smoke. In addition, the rodent nests often harnessed in its thicker, to get rid of which it will be impossible.

Ekwata.

Equata is a cellulose-based material. It is made from waste, adding a boor and boric acid. When contacting wood, such a insulation will play the role of the antiseptic, in addition, a mixture of 80% of cellulose, 12% boric acid and 8% of the borants is not a combustible, which is important for wooden buildings. Use eco-meat in the form of a bulk material, pre-breaking it in the auxiliary capacitance. Waterproofing is needed only from below, and the pairs coming out of the room can be kept by the thin-top layer of the insulation without losing its insulating properties.


Vermikulitis

Vermikulite is a mineral heat insulating material, which is used in addition to construction in the agro-industrial sphere. It is made without any chemical additives, is completely natural material, it does not burn and does not melt. His only drawback is the ability to actively absorb moisture and lose insulating properties, so its use requires a high-quality waterproofing device.

Article on the topic:

Principles of installation work

Floor insulation in wooden houses from below implies a complete dismantling of the existing floor. Carefully dismantled the first coating, the floorboards are removed and the remaining layers. The preparation process also implies a thorough inspection and identification of the cause of heat loss. They can be caused not only by the lack of insulation, but also the inefficient operation of the existing insulating layer. Most likely, it is caused by poor-quality waterproofing or insufficient insulation thickness.

After dismantling the boards, it is necessary to completely remove the heat insulation, if necessary, carefully dry it for reuse. The waterproofing layer is also deleted, and its state is analyzed. Installation of a new insulation layer can be started only when only lags remain from the entire design in its place, the remaining elements are removed.

Wooden floor insulation from below in a private house performed in the following order:

  1. Checked and, if necessary, replaced rotational lags;
  2. A plywood or any board is attached to the lags from below, that is, a raised floor is formed, the only task of which is to serve as the basis for the insulation;
  3. Waterproofing is stacked - dense polyethylene film;
  4. The selected thermal insulation is stacked;
  5. The boards are laid and the finish coating is restored.

What material to give preference

By efficiency, the main types of insulation are not significantly different from each other. For use in wooden houses, insulation are best suited, which primarily meet safety requirements, that is, they are not lit and do not distinguish harmful substances. In second place in importance, it is hygienic, that is, the ability to resist the occurrence of mold, colonies of insects or families of rodents, since in the conditions of a private house from such uninvited guests You can get a lot of trouble. The third criterion of choice is the convenience of installation and cost.

During the construction of the house, many do not care as much as the insulation of the floor. In order not to overpay for heating in the season, it is best to make a house suitable for accommodation in it in the cold season, insulation of the wall, ceiling and first of all the floor.

Very often, from under the floor blows cold, and the boards themselves are almost ice. There are several ways to insulate the floors in a wooden house after it is built by removing the boards and laying the selected insulation from the bottom.

Flooding takes place due to the sinking of boards and education between them. To increase the temperature in the house, it is necessary to carry out insulation under the floor using the selected insulation. This choice largely depends on the peculiarities of the construction of the house, its location and the necessary height of the layer of thermal insulation material.

When planning insulation, it is necessary to choose the material and designate its thickness, measured taking into account the construction of the house and the floor features.

The work process is clearly visiting you can look at the following video:

Insulation penplex

Penoplex - widespread material for floor heat insulation. Its high quality allows you to lay it once and forget about the cold forever - it will not crumble, it will not miss the cold and moisture, will not allow rodents to fill the underground.

Fulfill the floor by penplex can be with your own hands without resorting to the help of builders:

  1. Wooden lags are processed, strengthened and mounted in such a way that the space between them was no more than 70 centimeters.
  2. The insulation is then laid out, and on top for additional moisture resistance is covered with a film.
  3. After that, it is necessary to return the floors of the flooring to the place. The work is not complicated and does not take a lot of time.

Penoplex has a lot of advantages, the most significant of them are:

  • cheapness;
  • resistance to moisture;
  • easy to use.

To insulate the floor by penplex or other building material, it is necessary:

  1. First of all, you need to make a dismantling of the old floor, take off the boards, and, if they are unsuitable for further use, then prepare new ones.
  2. After removal of the board, the condition of the draft floor is checked, as it should be strengthened.
  3. To lags, it is necessary to attach to Paneur or any other board, which will serve for the insulation of the base and will not let him fail.
  4. Then you need to put waterproofing - the usual high-density polyethylene film is in its role.
  5. Then the heat insulation is laid out. It is necessary to trace the material to be laid out exactly, without the formation of cracks. After that, the vaporizolation is laid out, and the boards are returned to the place.

Foam insulation

Polyfoam, referred to as polystyrene builders - the most convenient, cheapest and durable material For heat insulation. It has high thermal conductivity and moisture-resistant, easily stacked and serves a long time.

However, he has a significant drawback - it strongly absorbs moisture, which is why thermal conductivity can be broken. Use the foam is best in wooden houses located in the south of the country, in places with a steady, warm climate and rare rains. In the houses located at the foot of the mountains and near the lakes, localities with frequent rains, it is better not to apply.

It should be borne in mind that the material is easily ignited, highlighting the caustic smoke, and often becomes the habitat of numerous rodents, to get rid of which you can only replace the sheets of foam.

To put the material, you need to divide it on equal blocks and lay between the boards so that the layers get from the base to the surface of the underground.

Warming with clay

Ceramzite is a traditional material for insulation of floors. It is high-strength, moisture-resistant and perfectly carries out heat. Main advantages: low cost and good thermal insulation. However, it is extremely inconvenient. It is sold in bags, and to properly put it, it is necessary to build special wooden cells, as well as prepare waterproofing.

Also, the lack of clay is its high hygroscopicity. Before displaying this material, it is necessary to pave high-quality waterproofing.

Ceramzite is placed in three ways: dry, wet and combined:

  • For dry laying The material you just need to fall asleep between lags. This is the easiest way that does not require great effort and time costs.
  • Wet laying It is that the material is mixed with concrete. This method increases the thermal conductivity of the clay. This option Suitable for houses with differential drops.
  • Combined method of laying is also good option Heat insulation. First, dry ceramzite falls asleep, and then the cement layer is poured.

Warming sawdust

Heat floors with sawdust - the easiest and most profitable option. Their main advantage is that they are imbued even in the most hard-to-reach gaps. You can drink them yourself or purchase bags in a construction store.

Styling technology is very simple: the floor is removed and the free space is completely covered with sawdust. The minus of this method of insulation of the house is that the material is not enough moisture resistant. After coating the floors, laying a layer of sawdust is recommended to lay a polyethylene film and only then close the floor with boards.

Eco-insulation

Eco-eco-friendly building insulation. Her advantages:

  • high thermal conductivity;
  • fire resistance - cellulose in the composition of wool does not flare up.
  • even after wetting, thermal conductivity remains.

The main drawback is high cost.

Before laying, the EcoWhat must be thoroughly loosen, and not to lay out a single thick layer. It is poured into the holes between the boards and is thoroughly aligned.

There are several ways to lay an eco-table under the floor. When you lay out the hands of wool sheets, you need to fit under the lags and close the holes using the mounting foam.

You can put an eco-button with a special device, through which the insulation is supplied under pressure.

When calculating, attention should be paid to waterproofing, in the case of its absence, it is necessary to pave between the floor and a thick polyethylene film that will protect cotton from wetting and extends its service life.

Warming Minvata

Mineral wool is a few species: glass gaming, slag and stone. In addition to the insulation of the floor, it has a lot of other advantages: absolutely not flammable, even when exposed high temperaturesIt does not allow to settle in the floors of home pests, cockroaches and rats.

When laying, you must use a special respirator. The main advantages of mineral wool: fire resistance and high thermal insulation, but there are also cons - it has low mechanical strength and absorbs moisture well.

When using Minvati, take care of vapor barrier and moisture-resistant floors.

Insulation foamball

The foam appeared relatively recently, but has already been distributed in the circles of builders. It differs from other insulation the presence of a thin reflective foil layer. It has many advantages: it is easy and durable, easily stacked, moisture-resistant.

When laying, it is necessary to close the joints between the sheets of scotch.

If there is no possibility to remove lags, for example, due to the fact that they are a carrier design, the floorboards should be removed and paved the insulation under them.

If it is for some reason it is impossible, then the floors should be firmly eliminated directly on the boards, and the laminate is fastened from above. However, this option is suitable only if the floors are strong, do not creak and have no cracks. If they are old, it is best to shift them anew, laying insulation under new boards.

Insulation isolon

Isolon - high heat insulation material. Despite the small thickness of the sheet, it is quite capable of replacing several centimeters of brick masonry.

The material has many advantages:

  • durability;
  • moisture resistance, resistance to rotting;
  • good thermal conductivity.

Laying is completely identical to the location under the floor of other thermal insulation materials. An old floor is removed, the isolone and waterproofing is laid out, then the boards are returned to the place.

What material is better to choose?

Choosing material for insulation of the floor, you should pay attention to the house area, cluster under the floor of rodents, cockroaches, moisture content of the region. According to its thermal qualities, each of the materials listed is reliable, the differences also relate to the price and durability, as well as the possibility of filling the material insects and its mold.

When choosing, you should answer questions:

  • what is the foundation of the foundation of the house;
  • is there a bias of relief;
  • whether in close proximity to the house of the river proceeds;
  • is there a basement or basement in the house.

The cheapest materials are sawdust and penplex. They are very convenient in montization and operation. However, if the house is subject to attacks of rodents and cockroaches, it is better to give preference to clamzit, eco-water and mineral wool. Equata and polyurethane foam are the most expensive materials, but quite reliable and durable.

When choosing a material for insulation, it is necessary to take into account the design features, as well as take care of good waterproofing, which will extend the service life of any insulation.

Independent floor insulation in a wooden house - 3 options for high-quality installation

Wooden houses in most modern people Associate with comfort and warmth. And in principle, this is true, because the wood is alive, natural, breathable material. But many of my acquaintances are methodically coming on the same rake, forgetting that the insulation of the floor in a wooden house is no less important than the insulation of the walls and roofs. In this material, I will first tell you how to insulate the floor in a wooden house three most available methodsAnd then go through personally on the use of each type of insulation specifically for wooden buildings.

Options for structures for floor insulation in wooden houses

Let's start with the fact that modern wooden houses can be erected as on a light pile or ribbon foundationand on a monolithic concrete plate, respectively, the insulation scheme in all these cases will be different.

In addition, floors in wooden houses can be insulated both from below, that is, from the side of the basement, and on top, from the side of the residential premises. Naturally, it's easier to do all this during the construction of the house, but not everyone is lucky and sometimes you have to warm the floors in the old house, which imposes your print prints.

Any capital types of work in wooden houses, including insulation of walls and floors, is recommended only after the end of the design shrinkage. And this shrinkage in the house collected from the dry forest lasts about a year. If a freshly left forest was used for construction, then the shrinkage can last up to 5 - 7 years.

Option number 1. Arrangement of thermal insulation in a low underground house

Low underground is the disease of most old houses and cottages. In my experience, almost all the owners who bought or somehow received a cottage built on the old manner, in soviet timesFights with a serious problem of cold, and often rotten floors.

Immediately I need to calm you, it is not necessary to break everything, if the Credit itself is still a whole and strong enough, you can warm the floor in a wooden house in your own hands in a few days, and for this, it is not necessary to be a bonding builder at all. It is enough to confidently use the hacksaw, a drill and a hammer.

As you probably have already guessed if there is a low underground in a private house, then insulation the floors will have to be top. And for this, we need to disassemble the whole design completely, leaving only carriers of lags;

If the boards and plinth of the first floor are in good condition, and you are not configured to completely change them, then when you tear down the flooring, be sure to draw yourself a laying sketch and numb each board. This will significantly save your strength and time when you start returning everything to your place.

  • When you got free access to lags, the first thing to do is carefully inspect the condition of the wood. Lags basic structure, respectively, they must be durable and reliable. If the number of rotten lag does not exceed 20-30%, then it is necessary to tinker with their restoration;
  • In general, according to the rules, the spoiled beam needs to be removed completely, and in its place to install the same. But this work is not for an amateur, there are too many small, professional subtleties. When I first encountered the problem of partial replacement of the carrier bar, then it came simply. "I cut out the rotten sector, and in his place put the same part of a healthy beam.
    This sector, I fastened on a screw with 4 standard metal corners of 35 mm, making an eye on an old beam of about 50 cm. But if there were no corners at hand, it is possible to fill the usual boards of a thickness of about 30 mm from two sides;
  • Now you can do the arrangement of the draft floor. Opinions on how it is necessary to do it right among the builders. The classical technology looks like this: with both sides of each lag, the so-called cranial bar is stuffed along the bottom edge. I recommend to take a cross section of at least 30x30 mm if you take thinner, then it may not withstand the load or burst from the nail or self-pressing;

  • The distance between the lags often ranges in the area of \u200b\u200b50 - 70 cm. In our variant, the draft floor will be collected from lags laid on a cranial bar, perpendicular to lags. Therefore, we will need to first cut these hundreds and well to impregnate with an antiseptic, as they are directly over the soil.
    For these purposes, a non-edged board thickness of about 20 - 30 mm is well suited. The question of what can be soaked, is solved simply: the market is full of various impregnations, but I went the simplest way, dipped each board in the development of machine oil;
  • I often ask a question whether it is necessary to mount the straps of the draft floor to the lags or the support cranial bruus. So, how much I saw and did myself, these planks simply fit into the cranial bar and that's it.
    Moreover, when you will refuse and cut off the planks, they need to be made by 10 - 15 mm already gap between lags. This tolerance is necessary to compensate for temperature and humidity deformations of wood;

  • Further, the instruction prescribes to lay a hydro or vapor barrier layer on the draft floor. The difference is this: if the soil under the house is dry and in your area does not have an abundant spring flood, then it is necessary to mount a vapor insulation membrane, and so that the steam freely comes out of the insulation, but in no case penetrated the soil into the insulation.
    Waterproofing is mounted in places with high levels groundwater and on wet soils. A technical polyethylene or rubberoid is most often used as waterproofing. Any of these membranes is covered with a solid layer of peaks, on top of the lag, with such a calculation, so that the draft floor is covered completely, without any gaps or cracks. I usually fix such a canvas stapler;
  • In the resulting improvised boxes are laid in the chosen insulation. Than you can, as well as the better to warm the floor in a wooden house, I will tell in detail a little later, now we will not stop at this;

  • The presence or absence of a vapor barrier canopy from above the insulation is determined by which materials were selected for insulation. But in any case, between the first wooden flooring And a layer of insulation must remain a small ventilation gap, 20 - 30 mm.
    For this, if there is an opportunity, the insulation is mounted a little, below the top slice of the lag. If there is no such possibility and the material is laid with lags, then you will have to be perpendicular to the lags to fill a wooden counter crate, with a step of 30 - 40 cm.
    Moreover, hydro or vaporizolation, if necessary, should be under the counterattack. Otherwise, if the finishing wooden floor does not ensure proper ventilation from the bottom, the boards will begin to deteriorate sooner or later;
  • The top layer, naturally, the finish wooden coating is stacked.

Option 2. Warboard Paul over the cellar

Proper insulation of the floor from below in a wooden house, in general, it is carried out by similar technologyBut believe me, doing it is much easier. After all, subject to the normal state of the final coating, you do not need to disassemble it. Otherwise, the technology is the same, only all actions are made on the contrary.

  • According to the rules, so that the insulation does not "stick" to the final coating and remained the necessary ventilation gap, it is necessary to fill in the upper part of the lag, on the border with a blank floor of a small cranial bar 20 - 30 mm. But to admit honestly, I never do that.
    It is much easier to fix with a stapler vapor insulation membrane, just below the first floor. No one makes you clear everything to measure everything, the main thing that the ventilation gap remains;
  • Mount the cranial timber and stern on the ceiling of the basement of the draft floor from the planks according to the previous technology, I also see no particular sense. After bookmarking in a niche of the insulation, so that he immediately fell away, I squeeze a number of small carnations on the lags and stretching a few strings from a fishing line or wire;

  • Further from the bottom, the whole stapler, the lags are attached to the canvas of waterproofing. And on top of this canvase, an unedged board or ordinary porch is stuffed to enhance the design. If the basement is raw and water is often worth it, it makes sense instead of the unedged board to put a galvanized profile under the ceiling under the plasterboard. I usually fasten it with a step of 20 - 30 cm, in any case, it is needed only to not falling the insulation.

For similar technology, the second floor is shown, or rather the wooden inter-storey overlap between the first and second floor of the lags. The only difference is that instead of a draft floor layer, it is most often from the bottom or any sheet material, such as plywood or drywall.

Option number 3. Warm wooden house standing on a concrete plate

Paul in a wooden house on solid concrete base You can warm on two technologies: installation on the lags and the arrangement of the screed. The choice depends on which end result you want to see and how much will be ready to spend money on all of this. Most often in such houses, the first option is used, on it on the finish you get a coating of natural floors.

Compared to the two previous options, concrete slabIn my opinion, it is much easier to warm up. As a rule, such a basis initially has an absolutely smooth plane, in addition, the weight of the warming structure itself does not matter here.

According to the first method on the stove you need to mount a wooden crate. She will be replaced by the same carrier lags.

Only at the beginning of the concrete must be causing a layer of waterproofing. In this case, it is quite enough, technical polyethylene. The thickness of the bars under the crate depends on the type of insulation.

For a full-fledged floorboard with a thickness of 40 mm, the installation step of the guide clamps oscillates within 50 - 70 cm. In the case when it is planned to sew the floor with thick plywood or OSB, the step is made of about 30 - 40 cm.

Concrete slab bars are attached by anchors. After that, exactly as when mounting on top, the insulation is laid in the niche, and the first coating is coated on top of it.

The insulation of the concrete slab under the tie is still easier. Looking a little ahead, I will say best insulation Here extruded polystyrene foam, we have more known as Penopelex. I will tell about his possibilities later, and now we will return to technology.

So this penplex, the solid layer is stacked on a flat concrete slab, attached to it and all the cracks blew foam. After that, you can choose: either put the metal reinforcing grid on it and pour the screed, or we are equipped with plywood, OSB or drywall and mount the floating technology laminate on it.

If you are interested in the workpiece under the "Warm floor" system, both for electrical and for the water option, the base from extruded polystyrene foam is excellent.

In addition to extruded polystyrene foam, such a floor can be insulated with clay. Of course, it will have to mess around, but the price of such insulation will be incommensurable less.

Technology here is about the same. Initially, concrete is covered with a waterproofing film with a wall at the walls, slightly above the finish coating. Further falls asleep and levels the horizon of the ceramzit layer.

It can be put on the clamzite and pour the cement-sandy solution, it will be a wet screed. Or put a double layer of plywood, OSB or drywall, it is already called a dry floating screed.

Choose insulation

How to make insulation itself we figured out, now it remains to find out what a heater for the floor in a wooden house is more suitable in a particular situation. So that you were easier to figure out, I specifically divided all materials into 2 large directions:

  1. Budget, that is, not expensive;
  2. And what is now called new technologies, respectively, the cost of them is an order of magnitude higher.

Traditional budget insulation

  • Patriarch in this direction is deservedly considered wooden sawdust. It is not difficult to guess that the price of them is kopeck, if you really try, you can even get a gift. But in order for this material to be used as a heater, it needs to be well prepared. Otherwise, after a couple of months, sawdust will begin simply rot.

First of all, remember, sawdust must be crippled in a dry place at least a year, fresh material does not fit. And in order for the mouse did not arrange a hostel in this insulation, you need to add haired lime there.

Since we are talking about independent preparation, I will take the courage to give you the 2 most popular recipe:

  1. For the floor, the bulk is best suited. Here, 8 parts of dry sawdust will need to be thoroughly mixed with two parts of the dry powder of hawed lime, in stores such lime is called meaton. In principle, the material is ready, now it can be covered in the space between the draft and the first floor.
    Only to achieve the expected effect, in the middle lane of our Great Motherland, this layer should be at least 150 - 200 mm. And in the northern regions, it can reach up to 300 and even 400 mm;

  1. It is much easier to work with plates. But these stoves will need to first make. In the composition of the solution, in addition to sawdust, there is still a funeral, and cement is added as a binder. Standard Proportion 8/1/1 (sawdust / lime / cement).
    Naturally, all this is abundant wetting and mixed well. When the solution is ready, it will fall asleep in the mold and slightly tamper. In the warm season, about a week later, the slabs are dried and will be ready for use. You can put the raw mix directly into the floor, but in this case you will not be able to sew a finite coating, because you have to wait a couple of weeks until the solution is completely dry.

  • The second number we have clamzit. This material in our country is used quite wide. Ceramzite is the granules of foam and burned clay. The material is porous, lightweight, durable and durable.
    The only drawback of him is hygroscopicity, the ceramizite is able to absorb moisture. Hence the conclusion, the ceramzite needs mandatory installation of waterproofing.
    As for the depth of insulation, it is approximately the same as in wooden sawdust. To improve the floor in a wooden house, you should use 2 fractions of clay, gravel and sand. So your mound will be more dense;

  • But almost the most popular in the budget sector insulation for the floor is a foam. The material is convenient in almost all respects. In the subfield, protected from all sides, the foam will lie for how long. Where kind of sawdust or ceramzite should be filled with a minimum thickness of 150 mm, it suffices to install a foam of only 50 mm thick.
    This insulation is absolutely indifferent to moisture and waterproofing here is mounted except to protect the wood itself. To install it, you only need to cut the plate clearly on the size of the niches, insert it and blew the gaps of the mounting foam.
    In a wooden house weak place Polyfoam laid in the floor are rodents. Very much they love to arrange their nests and fight it folk methods almost impossible;

  • It would not be fair to skip such a common insulation as a mineral wool. It is impossible to call it very cheap, but there are several inexpensive models in the line. In particular, glass gamble and soft mats of mineral wool are not expensive.

But honestly, I do not advise you to be honestly, this material is quickly pleasant, it loves the mouse and during wetting it completely loses its qualities. As you do not try, and soft wool will have to change about once every 10 years.

There are also mineral wool basalt plates, they are more expensive, but they are much higher density and quality. I recommend, if you mount your cotton, then take only the plates of thickness of about 100m.

From all above listed budget options Insulation, only sawdust and foam are considered combustible. Ceramzit and wool are a fire safety standard.

New technologies

  • Among the new-fashioned insulation are now hiking all records of popularity extruded polystyrene foam. It is a modern derivative of foam, both materials are made from styrene granules, the difference is only in technology.
    Plates of extruded polystyrene foam have a closed cell structure. As a result, the material does not miss the fact that moisture, but even steam. In essence, we are dealing with a good waterproofer. Above, I mentioned that Penoplex can be put into the screed, caused by the fantastic strength of extruded expanded polystyrene foam.
    If this material can be insulated with airfields, roads and concrete foundations, then the strength is small in a wooden house and nothing to say. In addition, his mice is also not particularly complaining;

  • The next number we have the so-called Equouth. It consists of at about 80% from cellulose, the remaining 20% \u200b\u200bcomes to anti-spyers and antiseptics. Equata in the production is not very expensive, because cellulose is obtained from crushed waste paper.
    I think the high price here is caused rather because the material is new. Mounting such a heater can be in two ways. If you are interested self installation, then wool just falls out in the floor cells and flies with a construction mixer.
    But it is better to order a machine joining. In this case, the wool with the help of the compressor is fond of any, including vertical and hanging surfaces. EcoWhat has one dignity in front of the rest of modern insulation, if you are confident in high-quality installation black and finishing floor, then in old houses you can simply make a hole and blend through it the entire underground eco-art;

  • Polyurethane foam pleasure is quite expensive. It is impossible to apply this material on any surface, it is impossible to apply a professional equipment and specialists with appropriate qualifications.
    In terms of its characteristics, polyurethane foam approaches extruded polystyrene foam, only a screed it will endure. The optimal option here is the gate of the floor from below in the wet basement. The fact is that foam hermetically closes the tree from below, and the warranty period of operation of such a insulation starts from 30 years;

  • Penosop will cost cheaper than polyurethane foam. But it also needs specialists to apply. Personally, I, in the case of the insulation of the floor in a wooden house, I see no particular sense to pay for such a material. After all, in fact, foamizole is the same foam, only in liquid form. Of all the advantages, only quick installation and hermetic solid coating;

  • For the last, I wanted to tell about the so-called insole. If you explain in a nutshell, then the isolon is a foamed polyethylene. It can be covered with one or on both sides of the foil, as well as go without foil coating. But the independent insulation for the floor in the wooden house is difficult to call it, most of the models have a thickness of up to 10 mm.
    With this thickness, the isolon can only go as an auxiliary coating. In particular, it is used in the arrangement of electric heating floor. Or sometimes they will additionally cover cotton wool. Foil isolon is a good waterproofer and personally, it often mounts it instead of the upper insulating layer under the piston coating.

Output

Heat the floor in a wooden house with their own hands is not so difficult as it may seem at first glance. If competently pick up the insulation and to prepare well, the floors in the mid-size house can be equipped with a maximum of a week. In the photo and video in this article, I placed additional information on the topic of insulation. If you have any questions, write them in the comment, I will try to help.
