In the event that the attic room is a non-residential, the air contained in the underfloor space performs the role of good thermal insulation along with overlapping insulation. In the case of an attic, everything is completely vice versa. Here, thermal insulation is located quite close to the roof material. It is necessary to make not only insulation, but also provide conditions for a long service life of the roofing system.
Speaking about how to insulate the roof of the attic from the inside, you need to know the list of basic works. Any wood used in the construction of a roof should be treated with antiseptics. This applies not only to rafters, but also a counterclaim. Thus, no wooden part should be missed out of sight. It is also necessary to take care of defense against ignition. For this purpose, wood is treated with antipirens.
The insulation of the attic from the inside if the roof is already covered, suggests some particular features. Any elements overlooking the street are processed by the compositions for outdoor work. Details made of wood and indoors are processed by impregnation for internal work. If applied composition for outdoor work Inside the room, it will continue the specific smell for many years. If you proceed on the contrary, wood can be damaged outside. It is explained by this defense deficiency.
Another important ruler of the insulation of the attic roof is the organization of the ventilation system in the undercase space. To this end, they are equipped with special ventilation holes. Through them go air, accumulated in the underfloor space. Together with you, he takes extra humidity. Hitting it under flooring the roof is carried out through the skes. It is impossible to do everything hermetically. The fact is that from there is a fence of air. Just at the expense of this, somehow it will be in time to dry, respectively, and the roof will serve for a long time.
If the attic floor was equipped correctly, then it remains warm in winter and cool in the summer. There are no problems with high humidity. I do not form icicles on the roof. As in the case of insulation, steam and waterproofing are a need. This comprehensive solution in which one without another or does not work at all, or is not well functions well.
When the broken roof acts as Wall mansard floor, the following layer is formed in the direction of the inside outward:
For what purpose over the insulation is the superdiffusion membrane? It is necessary to prevent the condensate or precipitation in the insulation, which leaked through the roofing coating. At the same time, she takes steam, which for any reason fell into mineral wool. Thus, he provides her drying. Optimal is the material with vapor permeability from 1500 g / m2. This layer is often referred to as waterproofing, but it passes steam.
Ideally laying of waterproofing occurs in the following way:
Waterproofing is often rolled over rafted to save, without pulling, and creating a sacking of several centimeters. This variant can also be considered good, as the moisture falls on the surface, after which it rolls down and goes beyond the roof. Another one an important point Is the yield of the membrane into a catchment chute. Due to this moisture, it will turn out from the underpants space.
You can highlight a number of moments of laying membrane. It stacked over the rafter from the bottom. The first option is launched into the drainbow. The next layer rolls up to the skate. At the ridge of the membrane on both sides, the material is stretched along the upper edge, after which it is fixed. Skate roll down the strip along. She descends on the same side of the roof. A coating is formed by which water can flush to a catchment gutter directly.
A separate word is worthy of vaporizolation. This also must be a membrane material. What products do not fit according to the characteristics:
The fact is that parry permeability of this layer, expressed in grams per square meter, must be minimal. Ideally, it is zero. It turns out that the material layer should not miss the pair from the room in the insulation. The use of mineral wool is very important. After wetting, it loses more than half of its own properties. If it freezes in the wet state and as a result melts, the structure will scatter it.
For this reason, the film is pair insulation with the occasion of one panel to another. Often, these joints are sampled by a special double-sided playproof scotch. This products resembles something sticky tires. Simple stationery or paint tape will not suit. It does not guarantee absolute protection against steam. In addition to the joints, any adjoits, located on top and bottom, as well as from the sides are also sampled.
Fixing vaporizolation occurs usually with a fist through a stapler bracket. Also suitable for this plank inner drying under the installation of the trim. Another ventilation gap is formed here. The lining can be fixed directly over the membrane.
It is difficult to answer the question, the better to insulate loaven roof. There is no unambiguous answer to it. Mineral wool is used hard modifications. Its density ranges from 30 to 50 kg per cubic meter. Harbor roof in most cases has significant angle of inclination. For this reason soft materials undesirable because they slid. We must take the plates. But in this case you have to adjust the step of the rafted under the dimensions of the insulation. It must be less than a plate of 15 mm. It will ensure the fixation of the Material of the Musphere between the shelves and its good fixing.
Laying thermal insulation is carried out so that the cold bridges are present in the minimum quantity. For the middle strip of Russia, it is necessary from 200 to 250 mm minvati. These are several layers of mats. When the slab overlaps fit between the rafters, they are placed so that one row overlap the next.
The width of the insulation must be somewhat wider distance between the rafters. In this case, it will be fixed tight. Clauses will be excluded. If the width is larger or less than the specified indicator, you will have to cut the material. In this case, it will be problematic to get smooth edges of the material, and there will be many residues.
Sometimes rafters have dimensions that do not allow to lay the entire insulation. Then heated the planks of the necessary thickness from the side of the room in the direction across. The rest of the insulation remains. From above, the vaporizolation is fixed and, if necessary, put the trim under the finish. This option can be considered almost perfect. There are no bridges, even rafters overlap. This method requires more expenses when installing. But such an attic will be exactly warmer. Accordingly, it will be possible to reduce heating costs.
Having an attic floor Provides many advantages. In particular, it is possible to stretch the end of construction. What should be done right away? To begin with, it is necessary to put a superdiffusion membrane layer on rafters and consolidated it. It is laid out the crate and roofing material. Warm attic from the inside after a while.
But it is important to pay attention to one moment. The waterproofing layer is mounted together with roofing. This represents an error that developers often admiss. They do not use the indicated membranes. As a result, it is necessary to remove the roof and put it either think of the system that allows you to correct these defects. The problem is that finding an economical solution that provides a guarantee of the normal state of materials in this case.
If all work do immediately, the procedure will be as follows:
Only after that they are finished with clamp or without it
This option makes it possible to push work on the interior for a certain period. This will be useful to those owners of residential buildings that have lacking funds. After installing the rafter system required to do the following:
This is the entire list of necessary work at the first stage. As soon as the ability to continue, it is necessary to make the insulation of the attic roof from the inside. It will not work so convenient. The fact is that it is necessary to equip the enclosing construction. She does not push the insulation higher than it is required. Mineral wool will have to somehow fix. She can fall on his head.
Algorithm of actions:
As for laying heat-insulating material, it is important to take into account a number of features. If mats are used from high density minvats, more or less simply. They themselves hold well. If you put the roll mineral wool, the work is complicated. When insulating indoors, the insulation is a steering direction in the bottom upward direction.
Take the lace, construction stapler. Rolled the roll and press the material to the speakers. The slice of the lace is fixed with the brackets, as if drawing the English letter Z. fixes the first layer, then - the second and the rest. In general, if I want to provide an attic roof with a comfortable temperature for any weather, l come to take mats of mineral wool With a density of 30 to 50 kg per cubic meter. They are pretty tough and allow you to keep the form of material. Softeful rolled products on vertical surfaces can be lifted. They seem to settle down, lowering the thermal insulation capabilities of the attic roof.
As mentioned above, mineral wool enjoys the greatest popularity. It is well suited for this purpose, but is not perfect, as moisture is afraid. Accordingly, you have to take care of its careful protection from all sides so that it does not lose its own properties.
Extruded expanded polystyrene or foam is used to cover the roof. Polyfoam is different good indicatorsBut allocates toxic compounds when burning. So-called self-fighting modifications with special additives can be detected. It is better to use them for the insulation of the roof.
The key advantage of foam is the available price. In the installation, he is pretty lung. It is enough to install the material of the versus between the rafters, after which it is closed by mounting foam joints. Use the foam for the insulation of the attic from the inside is convenient. You can order plates of the required size, which are 15 mm more than the lumen between the rafters. It is necessary to install them tight. Elasticity will allow them well to consolidate.
Ventilation clearance Leave from the roof side. Lay waterproofing. But it is most effective with respect to the wooden structure, as the polystyrene foam is not afraid of moisture. He almost does not absorb her and does not spend steam. The main drawback is hidden here. The fact that the material does not miss a pair, suggests that additional costs will have to suffer. It is necessary to equip a good ventilation system.
Extruded expanded polystyrene is characterized by more advanced characteristics. With the same conditions, the thickness of it is 2 times less than that of similar materials with the same density. Compared to the foam, this indicator is one and a half times less. It provides a system of locks, which reduces the possibility of the appearance of gaps, through which heat will go.
Another advantage is the lack of interest in the material from rodents and insects. Do not multiply on it fungus and mold. The only thing that imposes restrictions on its application is a solid price. Yes, and the ventilation system will be required in an additional order.
Many homeowners can be tempted to equip in the house comfortable noise attic. This desire is natural, this is a wonderful opportunity to increase the area and living space of your home. In addition, it gives the structure a special charm, brings some romanticism into its appearance.
Special mansard windows strengthen the impression. Today, most of the new private housing is immediately built with the attic. But often wanting to increase households, and in no new homes, the owners are equipped and the old non-residential attics are insulate.
Mansard are located almost under the roof. What requirements are usually presented? It is important that in the summer there was quite cool, and in winter dry and warm. So that the room meets the same requirements, it is important to know which processes in it proceed to understand the essence of competent insulation.
Perform all the necessary work with your own hands is easy, their technology is quite simple. The main thing for this is a conscientious partner and the presence of the necessary tools. If everything is technologically correct, it will not get cut out of wood and do not rotate, and the thermal insulation material will serve for a long time and reliably.
Housing under the roof - a special room. Its walls are close to the surface of the roof, while the ventilation gaps have the size of only 10-15 cm. This is associated with a characteristic feature of the room - it is instantly played in winter, and literally in front of the eyes. Through the roof in winter, such valuable for housing is warm, in the summer it is, on the other hand, heats up, significantly increasing the temperature of the room.
Taking processes depend on the quality of ventilation, as well as the thermal conductivity of materials used for manufacture.
In the summer it is late, heating the entire design, which is also heated in the room too much. If the building has a familiar cold attic, then everything happens differently.
The function of the heat insulator in such a housing performs the air in the indoor indoor, and the snow on his roof in winter.
Fucking materials on the floor, together with air, delay running from the bottom, from housing, heat.
Due to this, even in very frosty winters t in the attic room there is about 0 degrees. Snow outside does not melt, being another, extra insulator. In summer, T is regulated by the windows on the frontows, which play the role of peculiar ventilation system. How to insulate the attic?
The choice of optimally suitable material is a very responsible task. After all, it depends on it much - the thickness of the "cake" of insulation itself, the number of minimal layers in it.
Special requirements are presented to it:
Of course, all these items ideally, but it happens not often.
This is perhaps the most successful solution for insulation of the roof of the attic from the inside. It is a plastic material that compactly falls between rafters, closing all free space. Mineral wool does not support combustion and does not burn itself. It is extremely lightweight, and has excellent insulation properties.
Basalt wool in the plates wonderfully retains the form. Its disadvantage is that it easily absorbs couples and water, and therefore needs additional hydro and vapor barrier. It is very important: if the mineral wool gets wet, then it will irrevocably lose more than half of their useful qualities. If this happens, you will have to change it.
Despite this drawback, it is one of the most suitable materials For insulation of the roof from the inside. It just works with it, it has an affordable price. Strict adherence to technological instructions when working with it, there will be possible disadvantages.
This is a very popular and demanded material. But the use of polystyol attic to insulation should be considered more details.
The material has separate characteristics that can be considered virtually unique.
It is its extremely small thermal conductivity, minimum weight, low moisture permeability, perfectly rigid form.
But along with these wonderful positive qualities, he also has obvious disadvantages. Different varieties of material have a different degree of fire resistance. And for insulation, its combustible varieties is often used. And this is extremely dangerous. When fire, the fire rises up, and if the insulation is lit, survive in such a flaming attic will be almost unrealistic.
For work, the polyster is not too convenient, so with stronger, cutting and mounting it is quite crumbs. When it is used, there are gaps between the rafters, and they have to somehow close. From time it is destroyed, and begins to crumble even more. Based on the listed, it can be concluded that the use of foam in this case is not very reasonable.
This is a wonderful material for the insulation of the attic outside, for laying under the roof, on rafters. It is quite durable, perfectly retains the form, he is not terrible high humidity and, which is very important, it does not burn. Special attention deserves the fact that for insulation is required not very thick layer - 5-10 cm.
This is the material of the new generation. With the help of a special installation, it blends in the emptiness of the insulated material, not leaving no gaps and holes. Such a spraying allows preventing the formation of cold bridges.
This material is not terrible fire and water, it is lightweight, durable, keeps well. But there is a minus and he has an extremely low vapor permeability indicator: it almost does not breathe. Consequently, without the arrangement of forced ventilation, there will always be high humidity in the attic.
Perhaps this is one of the most suitable for insulation from the inside of materials, and its use is in fact the perfect option.
He, like the previous one, penetrates the smallest holes, filling all the intervals.
It is also extremely light, not afraid of moisture, absolutely does not support the burning and perfectly "breathe."
In addition, its cardinal difference from other materials is completely harmless to health and absolutely environmental. Neither the smallest particles nor even evaporation are equally harmful to health, in contrast to the same mineral wool.
Choosing, the better to insulate the roof of the attic, attention should be paid not to one of the performance characteristics of the insulating material, but also on the specific features of its use. It is more convenient to perform insulation of the room with a way from the inside: if there is no contraindications, and allows space.
Different types of insulation are used for this - and mineral wool, and extruded foam, plays eco-water or polyurethane foam. The key to the reliability and durability of the materials is to comply with the competent combination, or the "pie" of the insulation of the roof. It will provide and the comfort of living under it, that is, indoors of the attic.
When using cotton materials for insulation, a vapor insulation film is necessarily applied. With its help, the mineral wool will not be exposed to moisture coming from the dwelling with steam.
Regardless of the selected insulation, waterproofing will be required anyway. Its appointment is to protect the wooden details of the roof structure. The role of waterproofing is played by special superdiffuseous membranes, which are characterized by special qualities.
They can produce outside the steam, but at the same time not to pass inward moisture. Between the roof and the waterproofing membrane, you need to leave a gap for ventilation. Its size can vary from 4 cm to 10, depending on the material and type of roof. Through it, excess steam will be removed from the insulation.
More convenient to do this, while construction is still underway if it is already completed, it will have to remove the roof material. The external way of insulation of the roof preserves all available residential space as possible. Solving some designers also suggest beat the roof rafters as decorative interior elements.
For outer insulation, exclusively slab material has a high density.
These include penplex (extruded polystyrene foam).
The moisture is not terrible to him, and he does not need vaporizolation. "Pie" for outdoor insulation polystyrene foam looks like this:
Obvious plus of such insulation - Free access to rafters, at any time, facilitating their inspection and even repair. The method of insulation of penplexes on top of the rafter differs in the way that allows you to equip the heat-insulating protective layer to completely prevent the creation of cold bridges.
If the insulation uses the system of a special attachment, as a heater, you can take a glasswater with waterproofing and vapor barrier films. And under the planned wet facade You can successfully put ordinary foam. The main thing to achieve success is the strict adherence of technology.

This year we continue to insulate the attic.
Last year was completed with finished floors and trimmed windproof by the finalons. At the end of autumn managed to pour insulation in the frame of the frontones.
Estrase, remind, here. It is constantly updated and maintained up to date until the end of the mansard warming works.
This year, the task is to build inside the attic wooden frame, War down and sew it.
I build a frame from a bar 50 per 100. The bar was purchased last year and lay on the attic of the attitude of the whole winter. As a result, he was pretty strong.
Do not do so. It is better to use the timber immediately, while it is still raw and smooth.
At first I collected 2 frame shields on the vertical side sections of two walls. These shields obtained about 70 cm high and the length of the nasard's side walls. The height shield size was thought out in advance based on the planting size of the insulation of 58.5 cm. Under the location of the shields, both the floor of the attic was adapted, which was made last year.
Shields collected on the floor. At first I assembled the frame, then she crossed it with wind insulation, attached the insulation strip (isolon), and at the end, installed the finished skeleton shield in the place.
It turned out a low wall.
When installing the shield all the time checked its vertical level and adjust the slope. Fucked to rafters with ceiling metal versatile suspensions, and to the floor with self-draws.
At the end of the shield at the place of adjustment to the frontplates was the gap, which I stamped.
Under the shield at the bottom is visible layer of isolon 5 mm. The shield attracted to the floor with long self-draws in the locations of the floor lag. Thus, the shield was tight pressed to the floor and the cracks there are no, and the isolon remained in a compressed form between the shield and the floor for better thermal insulation.
Then I tried to obscure the shield of the insulation. The photo shows what happened.
Behind the shield remained such a triangular empty dismaying space. I will not use it, so it will be tightly closed.
This is a top view on the shy space.
The bars of the inclined walls were fixed directly on rafters with nails 150 mm. So that the nails are not allowed to crack on the tree, the ends of Bruusyev killed. Most bars were dry and twisted. I had to do so. A couple of pieces had to be replaced. The newly purchased bar unexpectedly turned out to be thicker than last year. In several places caught the thickness, as can be seen in the photo.
Gradually drew a sloping wall, or rather her skeleton. And then the future ceiling. Better do this work together!
Where was the need to use the corner for attachment.
Near the pipe made the frame.
After the frame from the bar was assembled. From the outer side of the frame, I began to mount the boards 100 on 25 as a outer crate, which will hold the insulation. In the ends and places of planning cold air, I made it all.
By the way, in that year under the winter I bought a gun for mounting foam, and before I took a foam with a plastic tube. And what am I tell you. Despite the fact that the gun is not cheap, he paid off for a couple of cylinders. Because at careful work with the pistol, the foam is consumed much less. It is not consumed by the vast piece of slices. In addition, the foam pistol can be left for a long time, even if you used only part of the cylinder. In general, I advise everyone to buy a gun and do not forget to buy a pistol cleaner, if you leave a gun without a balloon. I clean the pistol at the end of the season at the end of the work. And the rest of the time it lies under pressure with a cylinder of foam.
Dug out a doomlet from cropping boards.
Well, the doom is ready. We built a frame house within another house.
Here will be an attic space for venting. That is, this kind of "over the attitude of the attic."
Since wind insulation obviously not enough to purchase Axton films. But while I use it to the secondary places, as the Izospan has not yet ended.
I have no assistant. In order to smoothly pull the windproof film, I came up with a small device from a bar and a pair of ceiling suspensions. Now I hang the film as a curtain and gently fasten.
Suspension move as needed. Film a fastening brackets 53 of a type of 10-14 mm long with a stapler. There will be a separate story about the stapler.
Something like that we got the first trimmed span between the rafters.
And this is a top view of the prescription space. There will probably live a wasp (we have a lot of them, I do not have time to clean the nests).
For reliability, I decided to throw another layer of wind insulation from above. He also secured the stapler. It is not easy to climb the attack on the attic, and there is little place there. And in the sun day there is also baked from the corrugated floor. This second layer of wind insulation decided to add, as I am afraid that the birds will climb here and then the end of my insulation. In general, I hope to avoid this.
And this view from the attic down the wall of the frame. That is, this space between the roof and the frame of the insulation of the attic. Here the air will be tired. The hot stream will rise from the bottom up along the monsard wall and weathered through the grids.
The other day I finish stagger, then you need to insert the insulation (the frame was going under the size of the insulation), to strip from above the vapor insulation and plywood. In the photo, I tried out the insulation.
To be continued. If you have any questions, write, you may clarify some nuances or make additional photos.

The internal insulation of the attic has indisputable dignity - the possibility of conducting thermal insulation works regardless of the season. However, this approach has several important nuances, the ignoring of which can be reduced to no efforts and financial investments. It is easier to warn unwanted consequences than eliminating them, agree?
We will tell you how to act correctly to prevent errors. In the article, we described the features of the use of different thermal insulation materials, led advice on choosing a better insulation, and also told how to avoid condensate in roofing pie.
Detailed outlined technology of insulation of the attic roof will help to fulfill all the work independently, without resorting to the help of specialists.
Insulation there are plenty. However, not all of them are recommended for mounting in residential attic. For attic room It is characterized by a rather high humidity due to lifting heated air from the lower floors of the cottage. Plus both about environmental friendliness, and the safety of the material also should not forget.
If the attic is non-residential, then due to natural ventilation through produced, sofit and hearing windows Couples quickly destroys out of it. As a result, the condensate is not formed inside, and the rafter system is not subject to negative impact of excessive moisture.
In the mansard, the situation is different. When it is insteading, it is necessary to create a barrier to heat out and reduce air exchange with the street. As a result, the whole couple remains inside the attic rooms.
Therefore, if the insulation does not protect reliably from moisture, it will not last long. After all, any thermal insulation material after wetting partially or completely loses its properties.
When choosing a insulation, it is necessary to evaluate it:
If you choose too heavy material, the rafters will be overloaded. And the attic is often equipped with a non-residential attic. Stropile beams, in which case, are not designed for unnecessary additional loads. Testing fate is not worth it.
In thermal conductivity, most insulation presented in the market are similar. It is only necessary to correctly choose their thickness to achieve the required thermal insulation parameters.
Of the entire range of thermal insulation materials, for the internal insulation of the attic of the most suitable - mineral wool (basalt) and extruded polystyrene foam. Moreover, the first option is more preferable than the second. Minvat is not combustible and has better sound insulation.
It is not worth getting glass because of its predisposition to bribery. Small glass particles are very dangerous for a person. And the usual foam is also not recommended in the attic. In comparison with EPPS, it is more fuel and is environmentally friendly. In addition, it will have to lay a thicker layer.
Ideally, to warm the roof on the attic one should be outside at the stage of forming a roofing cake. However, it is often done on the contrary from the inside when the house is already covered with roof. And there are certain problems here.
Right and perfect roofing pie - several layers from different materialslaid on top of the rafter tightly on each other without cleansing. Such a sandwich guarantees that the dew point will be located on its external side. As a result, the whole condensate formed outside will quickly evaporate into the atmosphere.
By making insulation from the inside, after installing the roof, to form the above-described exemplary roofing cake is impossible. Put the insulation to the roof so that there is no emptiness completely left between them, it will not work.
But steam is always moving towards cold air. And then, each of the cavities formed will accumulate condensate and moisture. And this is a direct path to damage the material of thermal insulation and wooden elements of the rafter system.
For internal insulation Attic Dew Point has to be shifted into the space between the laid roof and insulation, leaving there additionally lumen in 5-10 cm for ventilation. Only such a technology and such a cake will avoid moisturizing the heat-insulating material.
To reduce the amount of water vapor in the insulation, its installation should be made using a vapor barrier film. Mounted vaporizolation from the inside of the attic over the material of thermal insulation.
Couples must first face this film and mostly stay in the room. The smaller it falls in the insulation layer, the better.
To insulate the attic from the inside correctly, it is necessary to create a cake of five layers, ranging from the roof inside:
Parosolation is made from pergamine, polyethylene or polypropylene film. The best option is special membranes, which have one side rough, and the second smooth. These materials have the risk of condensate formation directly on them is virtually zero.
For the organization of wind-moisture insulation, membranes are suitable:
Superdiffusion membranes are most effective for longer. However, they cost more than other options.
In this case, the perforated tissues and films when the residential attic of the residential attachment is recommended only in extreme cases. They are more calculated for waterproofing the cold roofs of inclined type on non-residential attics.
When installing with insulation in the warm room, these materials in severe frost are often covered with incident, which reduces their vapor permeability.
Before starting to insulate the attic from the inside with their own hands, first it is necessary to treat the wood rafted with antiseptics and anti-spires. Only then it can be started to form the thermal insulation cake.
If the insulation is reduced from the bottom of the rafted, then inner space Mansard will be reduced. The thickness of the heat-insulating cake often reaches 30-40 cm. If you take these centimeters from above and from the sides, the room may be too low and small.
At the same time, the installation option with the seamless cutting under the rafter and laying the insulation to it eliminates the appearance of cold bridges. If the Minvatu or Epps insert between the beams, then they themselves and the lumens formed over time in the heat insulating layer near them will pull the heat from the attic.
In order for the ventilation in the underfloor space to be relevant to the requirements of SPEPs, deflectors or other holes for air output should be provided.
Couples along with air flows should rise to the upper point of the roof and leave from there completely out. And this should happen without obstacles and as soon as possible.
Before fixing the membrane on the rafter, it is necessary to first calculate the thickness of the insulation. If the thermal insulation layer will be greater than the sizes of rafting beams, then you have to increase them with bars. The main insulation material should be inside this frame, and not oppose it.
In the upper part of the undermined underfloor cake, a material with high vapor permeability from insulation on the street and high waterproofing in reverse side. The task of this membrane does not prevent the exit of the steam out of thermal insulation, while the water and moisture in it, which can drip off the undercutting roof.
Most best Material For a given vapor-permeable layer, which also performs the functions of wind-moisture protection, is superdiffusional membranes. They are not blocked by dust and generated from condensate into severe frosts ice.
Laying of similar membranes is produced by horizontal stripes of the Vane 10-15 cm of the upper row to the bottom from the outside. As a result, it should turn out single cloth, when hitting which through the roof from the street droplets of water, they would flock down, not falling into the insulation.
The joints of the membrane rows from the inside of the attic are sampled by assembly scotch. It follows under the same brand as a vapor-permeable film.
The composition of the glue and the membrane material from one manufacturer is selected so as not to harm each other and securely keep in a glued state for many years. If they take them under different brands, then problems are possible.
The thickness of the insulation is selected in accordance with SNiP 23-02-2003. For this purpose, appropriate calculations are carried out, in which climatic conditions are taken into account, features design and roofing device, as well as the characteristics of the heat-insulating material and the inner skin of the attic.
The manufacturers of thermal insulation provide in the instructions to the material sold and lay out detailed recommendations on their official sites on the definition of this thickness. Focus best on these calculations.
Installation of insulation is carried out from the inside of the attic on top of the laid vapor-permeable membrane. If the mineral wool is selected, then it must be cut into pieces with dimensions by 2-3 cm. Wider lumen between rafters or fraud bars. Minvat must be among them with easy clicking and keeping there due to the right.
Epps will be put on top of the rafted, and not between them. Plates of this insulation are mounted on each other. If they are embedded inside the rafter beams, as minvatu, then through cutters will appear in the heat insulating layer.
Some craftsmen fill out similar lumets by mounting foam from the cylinder. However, you should not do so. This can lead to a damage of the membrane due to the chemical reaction of the components of the sprayed foam and the material of the vapor-permeable film.
It is better to take away 10-25 cm at the attic from the face and from the sides to the crate with Epps, rather than get a layer of protection with through holes.
On top of the insulation from the inside of the attic, vapor barriating from pergamine or polypropylene or polyethylene film should be laid. The task of this layer is not to start water vapor from the room in the insulation. It is laid as well as the most first vapor-permeable coating.
In addition to the usual film, you can also take foil. The additional foil layer will reflect most of the thermal energy back into the attic, reducing heating costs. At the same time, the installation of such a film is made by "aluminum" inside.
Fastener of vaporizolation is performed by stapler brackets or cloves with a wide hat. And in the places of adjustment of the film to cables, pipes and elements of the structure mansard windowsIt should be added to the special one-sided tape with the heat transfer coating.
At the end of the insulation of the attic, the cladding cladding is made. It is made from the bars with a thickness of 15-25 mm so that a small ventilation lumen remains above the vapor barrier.
Bruks of the crates on the one hand are designed to fasten the casing material, and on the other, it additionally fix the vapor insulation membrane and pressed it to the insulation.
The shelving itself can be painted or bred. Options for its finish there is a mass. You can also not attach drywall and chipboard at all, but immediately fill the cladding on the crate.
A description of different methods of thermal insulation of the attic roof is presented in this article.
Overview of the technology of mansard insulation:
Condensate due to improper vapor barrier and how to get rid of it:
With independent insulation of the attic from the inside, when the roof is already covered, it is important to choose the thickness of the heat insulating material. It is even more important - to carry out the right installation without gaps of vapor barrier and wind-moisture insulation.
If protective films on both sides of the insulation will have braces, then it wureswards and stop protecting the house from the cold.

Frame house with an attic - a rational solution for country construction. Two-level design With a large area of \u200b\u200bpremises occupies a minimum of space. Built in framework technology, the house is easy to inspire. To prepare an attic to operation in the cold season, it is enough to isolate the walls and roof modern materials With clear compliance with standards.
With the task really cope with yourself. But if possible, it is better to attract professionals to the construction of a frame house, which organize the insulation of the attic without the risk of violation of standards, taking into account the regional climatic conditions and individual characteristics of the project. Effective isolation will continue to reduce the costs of the maintenance costs.
A competently mounted frame house preserves a microclimate, but without a heating system in winter it is not necessary. The advantage of mansard premises is the top location. Warm air rises, so the heating communications at the lower level is enough to heat the entire frame house. But in the case of improper insulation of the roof of the heat loss is inevitable.
With autonomous accommodation in country house The issue of reducing energy consumption in priority. To avoid additional heating costs, the mansard warming should take seriously. Ideally, it is necessary to insulate the frontons of a frame house, inter-storey overlap, roofing and top-level ceiling. With competent insulation, the attic does not require separate heating.
When implementing most architectural projects on the walls of the attic, the frontones of the frame house are coming. If in the installation process, the rules for the formation of a multilayer "cake" are not violated, with the insulation of the side surface of the problems does not occur. Special attention is required to connect with a rafter design and window openings. Sealing risk areas will eliminate cold bridges. "Pie" walls includes:
The thickness of the walls of the frame house is determined by construction regulations. In the northern regions, insulation is produced in several layers. If the measures taken during the construction turns out to be not enough, additional insulation of the attic of the attic from the inside is allowed. When insulation frameless walls We must not forget about ventilation, be sure to leaving air gaps before facing layers.
The specifics of the attic lies in the fact that the main part of the space is protected from external factors only with roofing design. That is why the warming of the roof should pay increased attention. Roofing "Pie" is drawn up by the same principle as when mounting the walls of a frame house. The facade casing replaces the outer coating, and the inner finish is the surface of the attitude of the attic.
Popular European style in interior design is based on original aesthetics wooden beams under the roof. Following fashion, the owners are often neglecting the ceiling equipment. It is really easy to organize a spectacular finish under the chalet in the attic. But the absence of the ceiling is not always appropriate, as an additional design is important not only for aesthetics, but also for insulation.
In compliance with the other requirements for isolation of the skeleton house from the insulation of the floor of the attic, you can refuse not to increase the load on the foundation. However, when making a decision, it is worth considering sound-absorbing characteristics. Insulation of the inter-storey overlap reduces the noise level in the premises. After all, silence is a mandatory attribute of a real coziness in a country house!
In cases where the roof is already covered with the main material, the mansard insulation is carried out from the inside. It is possible to equip high-quality and, most importantly, effective thermal insulation for a residential attic room is possible in several ways.
The differences between them are mainly in the type of the selected insulation, and otherwise the technology is based on the same rules that are briefly described below.
But for a start, it is necessary to stay in more detail on the question of what major and additional advantages gives insulation of the attic. After all, many believe that the thermal insulation of roofing structures has a positive effect only on energy savings used for the heating of premises. However, this is not all the advantages that appear after the insulation of the attic roof from the inside.
So, in addition to the fact that the thermal insulation layer allows you to noticeably reduce the current costs of heating in the winter period, passing the roof insulation gives such advantages:
Thus, the insulation of the attic roof from the inside is a profitable investment of funds, which allows to extend the service life of materials, reduce heat loss and noise level, increase the comfort of room and coolness in the summer period.
Now it is necessary to stop on materials in more detail, which is allowed to heat the roof of the attic. Such products on modern market Several, and they are divided into three main categories:
The first two categories have varieties that differ in operational and heat insulating characteristicsTherefore, they are worth talking separately. Polyurene foam is also different, but the main parameters for all brands are almost the same.
So, mineral wats are divided into two large groups. The first group is glass gamble, that is, a mineral wool based on fiberglass. It is done with the use of the same raw materials from which ordinary glass is made, that is, from quartz (the famous sand). The second group is basalt wool, or the so-called stone wool. It is manufactured by the same principle as the above-described product, only instead of quartz melts and stretches into the fiber natural rock - most often basalt.
What is better from this, and what is worse, it is difficult to say rather, since the glass gamble is cheaper than a stone analogue, but according to the characteristics a little inferior. In addition, glass fibers create quite a lot of problems when installing thermal insulation, while basalt wool is freely taken by hand without gloves and without consequences.
The advantages of mineral wat:
Disadvantages are also there, but the most weighty one is the ability to absorb and accumulate moisture. And therefore, with the insulation of the attic roof, from the inside with the use of mineral wat, you need to pay special attention to hydro and vaporizolation (there is information about it below).
The polystyrene foams are also divided into two main groups. The first group is cheap foam plates. Their main features are low cost, low density and ability to crumble from the slightest physical influences. This material is accurately rodent, you need to gently handle it, and it partially absorbs moisture.
A more advanced heat insulator of this category is the so-called extruded polystyrene foam. Unlike cheap foam, it is much denser and has almost zero porosity, which means absolutely not subject to the accumulation of moisture. In addition, the extruded polystyrene foam does not like rodents, it is easier to work with it, and it is much more durable than a cheaper counterpart.
It should be noted that any kinds of polystyrene absorb noise much weaker than even cheapest mineral wool. Therefore, if along with the insulation of the attic roof, there is a question about noise insulation, then preference is better to give in favor of fibrous materials.
The last group of thermal insulators, which can be combined with the insulation of the roof from the inside, are polyurethane foam. Despite the rather complicated name, this material, or rather his close analogue, is familiar with almost everyone who has come across construction or repair. According to the composition of polyurethane foam similar to the usual mounting foam. The principle of its action is almost the same - after applying to the surface, the chemical components interact with oxygen and moisture in the air, expanding at the same time repeatedly in volume, and crystallized into a solid stable mass.
The main advantage of polyurethane foam lies in its ability to penetrate into the most hard-to-reach places - cracks, seams, joints, angles - which cannot be achieved when using mineral wats and expanded polystyrene. Due to this, the heat insulating layer is obtained by monolithic, that is, seamless, and all sorts of cold bridges are excluded by themselves.
The insulation of the residential attic with the help of polyurethane foam in many causes doubts, since this material is sufficient toxic. However, this is only during its application and crystallization. After the foam completely freezes and turns into a crust, it becomes absolutely safe, and even the smell does not have any smell.
To serious disadvantages of polyurethane foam, perhaps, it is worth considering only the complexity of her spraying. For this process, the technology provides for expensive equipment, which there is no particular sense to carry out the insulation of the roof of the attic once. Because it is decided to use polyurethane foam, you will have to seek help from specialists.
Whatever material was used to insulate the pitched roof, there are generally accepted principles that specialists adhere to in all common cases. These include the following highlights:
Otherwise, the process of the insulation of the attic may differ by the subtleties due to the selected type of thermal insulator. Highlights for the materials described above are considered in brief below. Including attention is paid to such questions as: preparation of material, sizes, laying and fixing.
Technology for the insulation of a slim roof of a glassy or basalt cottage is performed in the following sequence:
The process of the roof insulation will be slightly different depending on which the format is bought in the heat insulator - in rolls, or in the plates.
That with the help of the budget foam that the polystyrene is extruded, the insulation of the roof of the attic is carried out in the following sequence:
With the insulation of the attic of the attic polystyrene foaming, it should be remembered that this is a fairly fragile material, inclined to painting in carelessly. If there are cracks in the installation process, they also come with them, as well as with seams - close with adhesive tape.
The most efficient and, at the same time, expensive warming of the roof from the inside is the application of polyurethane foam.
As already mentioned above, this procedure is not all for the pocket, and it may not always be done. However, this technique of insulation of the pitched roof from the inside there are several pleasant advantages that none of the above materials are posted:
In addition to the high cost, insulation polyurethane foam attic requires attention from the strength of the rafter frame. The fact is that with the normal thickness of the heat insulating layer, this material in weight significantly dominates the mineral wool and foam. Therefore, before proceeding, it is necessary to strengthen the framework with a new weight load.
Otherwise, the technology of insulation of the roof from the inside with the help of polyurethane foam foam is not much different from the above procedures. It also places waterproofing, vapor barrier and air interlayers for normal circulation and removal of accumulating moisture.

Attic at home - space with great potential. It has a spacious area to serve as a place for storing things or seasonal rest, and a non-trivial form that can be the basis for incarnation. designer ideas. Do not use its capabilities - a great omission.
Organize the space of the attic floor can be in different ways.But the most rational one is the arrangement under residential premises. This will help independent insulation of the attic from the inside. The choice of material and the order of work will also not make much work after a detailed consideration of the characteristics of the materials and the process of insulation.
Good, warm attic has a number of advantages over the laptile floor:
At the same time, the insulation of the attic, despite the name, works in the opposite direction. Summer stuffing and heat concentrated under the roof of the houses are not the best comfort satellites. So that the air in the area of \u200b\u200bthe attic floor does not heat up because the sun warms the roof all day, the heat insulation is needed.
Many forget about it by choosing the insulation of the attic room from the inside, and instead of a room for all-season use, a version for wintering is obtained. In the summer there is impossible to be due to high temperatures and stuffy air.
For what to insulate the attic clearness:increase the useful area of \u200b\u200bthe house by turning the attic to the residential premises. What specifically the type will be this room depends on the individual needs of the family. A greenhouse can be placed there, the dining room (which is very convenient, because it will be easier to arrange an extract, and the smells of food will definitely disappear into other rooms), a children's room, a bedroom, a room, a room for pets, a dressing room, a guest room.
The convenience of the attic for living largely depends on its size and shape of the roof, which forms the walls and ceiling of the room. The complexity of the insulation procedure, the form also affects. The roof type is laid during construction in accordance with the building design.
There are only a dozen types of roof types, to one degree or another suitable for the arrangement of the attic:
When it comes to the insulation of the attic, it is necessary to consider several types of SNiP: general rules for the arrangement of residential premises and the rules for choosing materials for the thermal insulation of residential buildings.
In one, if the documents are decorated correctly and the construction of the house occurs immediately with the attic, it can be reworked in any way without unnecessary red tape.
In a private house, the construction of the attic depends only on the height of the floors and compliance with the norms of load on the supporting structures, it is important in an apartment building to take into account its status. If this is an architectural monument, the construction of the attic will fail.
With the arrangement of the attic, especially wooden, under residential premises, you need to comply with all the requirements: to process a tree with special impregnations that prevent the spread of the flame, choose fire-resistant materials, highlighting communications.
It is also important to calculate which layer is needed when using different materials. As a rule, the recommended thickness and density of foam, minvati, polyurethane foam or foam glass is indicated by the manufacturer or GOST for a particular material.
The materials themselves offer the construction market in excess. At the same time, only insulation is not enough because the technology implies layer-by-country use of various purposes:
If there are no questions with most points, the choice of insulation is the most responsible moment. Its selection is wide, which is at the same time plus and minus, as it is necessary to evaluate a large number of options.
Warm attic:
Use for thermal insulation of sawdust is a proven and effective method. It is cheap, mixtures are prepared personally, but in the presence of alternative materials, the method is already outdated. There is a lot of time, work with widths is clean, but unpleasant, and the durability of the flooring will not differ. Environmental purity in this case is rather not on hand, because wood fibers are an excellent medium for breeding organisms.
A common foam belongs to the past the materials. A number of advantages It has: Little weight, low price, simplicity of mounting alone, quite a long service life, good insulating properties. But the shortcomings are still significant: the brittleness and fragility, delays moisture inside, a suitable medium for the reproduction of living organisms, a thick layer of material is needed.
Mineral wool is a more relevant insulation. Her advantages:
Disadvantages:
Equata is in its essence represents cellulose fibers per three-fourth parts of the composition, and there is a substance for the remaining proportion, allowing the use of cellulose as a building material - this is a boom and boric acid. They increase the firefightness of the wool, prevent the appearance of microorganisms, fungi, rot.
The advantages include the good ability of the insulation to maintain heat in the room, do not interfere with ventilation, high-quality insulating properties, natural and safe raw materials are equally.
The minus of the material also has, and significant. Equata is not made in the form of plates or sheets, it is a crumbly fiber, which must be applied with a wet method when using special equipment. And to work with the equipment you will need qualified installers.
In addition to eco-house, foreign manufacturers offer other types of plant fiber-based insulation: ecolean and cotton fabric insulation.
Another variety of wool is basalt. It is relatively mineral. Since its components are present in the composition, but the basis of the material is the basalt rock. Basalt reports material unique qualities.
His advantages:
Disadvantages:
Similar characteristics have the third variety of wool - glass gamble. It is more convenient to use, since the material is rolled.
Extruded foam or extruded expanded polystyrene combines the qualities and advantages of mineral plates and ordinary foam, thanks to the special production technology.
His performance features Mostly positive:
The minuses include: vapor permeability, low fire resistance.
The group of gas-filled plastics of the new generation includes polyurethane foam (PPU). His advantages make the material one of the best for the insulation of the attic floor: it is lightweight, moisture-proof and fire-resistant, does not accumulate dust, does not attract living organisms, very durable.
There are two types: sheet and sprayed.Sheet material is very convenient because it does not crumble in the process of cutting fragments and the detail to the part can be clenched. The sprayed type of protection creates a monolithic layer under the roof, due to which it is not afraid of sediment, cold. And also it is characterized by good adhesion with various surfaces, resistant to the emergence of microorganisms and allows installation work as soon as possible.
Sprayed material creates better thermal insulation and contributes to the muffle of foreign sounds, but he has two serious shortcomings. First, it will take an expensive service of professionals with special equipment for applying. Secondly, it is so dense that "does not breathe." In the room will accumulate wet and sower air, if not possible to organize additionally ventilation.
It is advisable to apply both types of PPU at the same time.Large plots are closed with sheet material, and hard-to-reach places and gaps are treated with spraying. This will completely solve the problem even the coldest attic.
The foam glass is small and unfairly moved to the background material. The reason for this is simple - a very high price. The foam glass, as already understandable from the title, is obtained by foaming fiberglass. It turns out porous (cellular) material that is absolutely not susceptible to fire, is safe, durable and satisfies all the requirements for insulation. If financial capabilities allow, the foam glass as thermal insulation should be considered first.
A separate group from plastic and glass derivatives is foil materials for insulation of rooms from the inside. By themselves, they have a small thickness, so they are often combined with various variations of foamed cellular materials, which are inside between two layers of foil.
The advantages of reflective materials are obvious:
The choice of a suitable insulation is the responsible stage of the living room arrangement on the attic floor.
Several important factors must be taken into account:
Masters and type of materials used when finishing the roof.
The insulation of the Ceiling of the attic under such material is correctly carried out with the help of a layer that is not afraid of moisture. Features of the structure and installation of metal tiles are such that water can fall under it. Optimally, the use of foam materials based on plastic or glass, but if the choice fell on mineral wool, it is important to take care of a good waterproofing layer.
It is also necessary to choose a material with anti-condensate coating. After the condensation reaches a certain temperature, it will also turn into a dangerous water for the insulation layer. It is possible to solve the problem with the help of polypropylene films, geotextile coatings and superdiffuse membranes.
The disadvantages of metal tiles include the fact that its unusual form allows the precipitation to accumulate between the coating layers, which is almost impossible to be completely sealed. Maximize the damage from this will help high-quality ventilation under the roof. Natural in this case may be little, it is necessary to equip forced.
Such problems also apply to ceramic embossed coating and slate sheets. All of them have the same shape that does not allow you to fit the sheets closely.
It is less problematic in relation to leaks and condensate, as the sheets are tightly adjacent, and the compounds are processed by sealant and paint. But the material has its own features. First, it is very cold and the insulation must be high-quality and impressive in thickness. Secondly, during the rain under the roof of the professional flooring, it is very noisy, we need material with high indicators of sound absorption.
From the list of suitable materials you need to eliminate thin foil sheets, fiberglass, cellulose insulation by the type of ecolna. Their thickness and sound insulation indicators are not sufficient to provide a comfortable stay in the attic under the roof of the roof.
Along with the type of materials for the roof, it is necessary to take into account the location of the attic: or it is over all residential premises, or above the house.
One of the problematic options is a attic of the bath. With this location, it is difficult to equip a residential premises in it. It is more suitable for a relaxing room, a small living room or a game corner, which is necessary after bath procedures.
The main difficulty in choosing the materials is to the microclimate of the room above the bath, different from the microclimate over residential rooms. The temperature-humid mode is unstable, and the possibility of condensate is very high. Of course, under such conditions, neither sawdust, nor wool, nor environmental insulation based on cellulose. Here are necessary hydrophobic materials according to the type of polystyrene foam and polyurethane foam, foil coatings, good vaporizolation forced ventilation.
Universal solution for the insulation of the horsard of winter accommodation does not exist. It all depends on the climatic conditions and materials used in the construction of the house.
Long and harsh winters are solid, porous, resistant to temperature drops insulation. The warm climate is any material suitable for the type of roof.
In a private wooden house, due to the properties of the tree, to keep the heat is quite thin insulation. Cellulose-based materials are suitable, glass or plastic. You can use foils with minimal thickness.
IN brick houses With roofs of corrugated flooring, tiles or slate, additional insulation is needed in the form of airspace. It may be dense porous materials and several mess between them. The insulation of the frame house does not require much effort, since all features of specific climatic conditions are already provided in its design. Here are any moisture-resistant and fire-resistant materials.
The technology of creating thermal insulation in the attic is available and non-professional. The key to success is not in experience mounting work, and in the correct selection of material, consistent action to create a solid insulated circuit and accuracy.
Procedure Next:
It is important to docile well in the corners of the fronton and in such complex areas, like Konk, Endov, Sveza. For this purpose, small parts of the material are used, separated by a sirry.
Special attention is paid to the contour of windows. The room will remain cold if warm air will go through the window slots.
The sequence is such: the insulation of the roof, overlapping, fronton, partitions, walls. The floor can be inspired both before and after.
The insulation of the floor is more variable, since it is less than the effect of precipitation, winds and frosts.
It can be a dry beep, and sawdust, and mineral wool:
The correct thermopyrot for insulation of the roof is mounted in compliance with many nuances.
Non-professionals often make the same errors that affect the quality of the insulation of the attic:
Usually the house is built quickly, often for the summer season everything is supplied under the roof. After the interior decoration, you can settle, engage in the improvement of the local area and the expansion of the functionality of the house. In this article, we will tell how to make the insulation of the attic from the inside if the roof is already covered. The information will help determine the choice of material - this often depends on the initial conditions, explains the subtleties of its correct application.
Warming already covered roof has its own characteristics about which you need to know Source Pinterest.com.
After that you will talk to the builders "in the same language." That well stimulates them to offer and demonstrate the best and best and fulfill the work even better.
Let's start with the fact that the attic a little special room. Its general device requires a thorough scrupulous approach. And the insulation of a naked roof, especially:
Insulation will have to be mainly vertical or inclined surfaces. Therefore, it is better to immediately exclude all the soft "pliable" materials, namely the rolls of mineral wool.
It is advisable to navigate on materials with a small one's own weight. Since the rafter system of already experiencing significant loads from wind and snow. In addition, the load on the bearing walls will not be much.
Often insulation required fRONTONAM. They are not always performed by analogy with the capital wall. May be made of facing material. Or simply arranged a frame under the insulation.
It happens that the area of \u200b\u200bthe attic significantly surpasses the size of the houseAt the same time, part of it relies on the columns. In this case, it is necessary to insulate and overlapping, in contact with the street.
If the attic floor stands outside the house, the optional overlap warming is required. Source Metasold.com
It should be understood that the thickness of the insulation must correspond to the weather conditions of a particular climatic zone, while have a small supply. To gain the necessary thickness, the insulation is mounted in several layers, and relatively small dimensions suggest docking.
IMPORTANT: A careful approach is needed to the splicing of any insulation. Shakes of different layers should not be focused in one place. To exclude the freezing, you should disseminate them for the maximum possible distance. It is important to constantly remember this, so as not to spoil the material, especially performing the insulation of the broken roof.
We will end in more detail on the insulation of the house with foam. How safely Polyopolster Find out in our video:
It happens that the width of the rafter does not allow you to score the necessary soaplitel thickness. To continue needed an additional framework. It is better to arrange a cross, from this, the entire rafter system will become more stronger. And the insulation is more efficient - an additional insulation will block joints of the main insulation and rafters.
On our site you can find contacts of construction companies that offer a turnkey house insulation service. Directly to communicate with representatives, you can visiting the exhibition of houses "Low-rise country".
All wooden surfaces need to be treated with antiseptic and fire impregnation.
All wooden nodes must be processed by protective materials Source Remontik.org
On the structural elements you need to immediately identify "unreliable places". For example, the adjoining of the extreme rafters to the fronton of facing bricks. Or the connection of the shaft of the raftered with a screed, made without insulation. It is necessary to eliminate the flaws - whenever possible, make them or beat the sealer. Otherwise they will not be able to withstand through blowing and freezing.
It is necessary to minimize the use of metal fasteners. This is especially true of metallic linings pulled by bolts. Of course, the bolted connections will remain, but the plates are worth producing from thick durable plywood and replace. The remaining metal pieces are painted ground enamel and are covered with a layer of mounting foam. Directly in the insulation, the metal is a source of condensate and dampness.
Excellent when the insulation of the attic of the attic from the inside was planned in advance, or "just in case" the structural moments for this builders were observed:
Roofing membrane is mounted on the rafter.
There is a counterclaim.
The step of the rafter, corresponding to the widespread length or width of the insulation, is set.
It is convenient to carry out insulation, if it was planned at the construction stage source Bamban.ru
It is worth noting that these are ideal source data that allows not to look for "output from the situation", and insulate the maximum scope of the attic qualitatively without unnecessary costs. Such conditions make it possible to use vapor-permeable insulation. And this is a comfortable living conditions.
When the decision on insulation is accepted forced, the roof is usually not prepared. There is nothing terrible in this, it is even possible to choose options:
Conduct warp materials that do not require waterproofing.
Evaluate a special frame for residential premises.
In case of insulation of the roof not prepared for this, special compositions can help Source PasprayPros.com.
A special role can play foam polyurethane foam. Although equipment is needed to apply, but insulation is a solid layer, and does not depend on constructive features Roofs.
Foamed polyurethane foam one of them Source DA.DecorexPro.com.
This can also be attributed to Ekovatu. Although it requires a roof membrane for its device, but the insulation layer is quite realistic to perform solid.
In our video, we will look at how foam is produced, is the foam harmful and where is it used?
Due to its elasticity, the mats are well held between rafters, allow installation without additional fastening. And relatively dense structures of the stone wool eliminates its shrinkage over time. Therefore, she has proven itself on vertical surfaces.
Matte stone wool come different thickness, and you can choose the necessary on the basis of the climatic conditions and other materials used by the source Pallazzo.su
To reduce risks, every 3 meters of height need to arrange support for the insulation - add horizontal framework element.
Public popular material - Penopelex. As the insulation is very effective. Its application is justified in the territories of the country where mineral wools are not used expedient - need a large thickness that significantly steals the space, and the cost is prohibitively large.
In normal conditions, it significantly saves the place when each unit of volume is important:
It is possible to mount between rafters of small width, while the insulation will be effective.
It does not require additional waterproofing, as it does not pass water itself. That is, the absence of roofing membrane is not critical.
However, it is also desirable to preserve the ventilation gap with the roof, for the rapid removal of condensate vapors. So rafters persist much longer, because they are not protected.
Extruded polystyrene foam does not require mandatory waterproofing Source Pt.DecorexPro.com.
Having inspired by the penplex, it will be worth it to take measures to enhanced fire safety. For example, use open electrical wiring, laying it constructively as designer solution. The thing is that Penoplaks himself does not support burning, but at high temperatures melts very quickly.
The insulation is mounted, but the process should also be completed correctly. It must be protected from wet vapors from the premises. For this, a vapor barrier film is mounted. Moreover, the general result is highly dependent on the thoroughness. Although the instruction is equipped with each packaging, briefly repeat:
The subsequent cloth overlaps the previous one at least 15 cm.
The joints are sampled special scotch.
However, the platoosolation of the attic has a dual purpose. Whatever enough, but she protects the tenants themselves. The fact is that vapor-permeable insulation is not enough durable and is amenable to insignificant weathera. Outside it is not so important, plus it protects the roof membrane. And inside it is necessary to eliminate even the minimum possibility of separating the insulation components into the air - to secure it.
The final stage becomes the insulation of the insulation with the canvas, which later falls the finish Source Obustroeno.com.
Of course, this does not concern Polyeplex. But it is recommended to protect itself, effective material - foam.
As for the insulation of any type. In addition to the vaporizolation device, it is often used, at first glance, an unnecessary but effective admission. Before the finish finish, the intermediate, it would seem extra material. This may be an OSP, GVL or GKL - depends on the constructive. And fully observed technology - all joints are carefully close. This is an additional barrier from the unwanted effects of materials.
On the insulation of the attic from the inside in the video:
It turns out that the insulation of the roof from the inside if the roof is already covered quite possible to do high quality. Moreover, not only planning everything in advance, but also for a long time finished roof, absolutely for this is not adapted. Now, knowing the subtleties of the process, much easier to choose a good artist for such a responsible case.
