The insulation of the attic from the inside if the roof is already covered: the choice of material and the order of work. How to insulate the attic from the inside if the roof is already covered? Insulation of broken attic from the inside

As we all are known for certain, the tariffs are not cheaper, so many owners of country cottages are thinking about maintaining heat. Any builder will tell you that the house, at its base, loses heat through the roof. In a number of buildings is present mansard Floorwhich can be very cold. Therefore, the insulation of the attic is a very important task requiring a thorough and thoughtful approach to its solution. If you treat it with neglect, you can earn a miscalculation, which will be very expensive to you after a little time - much more expensive saved money on the attic.

You will be able to insulate the attic of the attic from the inside of the roof, but it will be better if the external layers of the insulation will put professionals. Therefore, our material will hold a libez in insulation and tell how to insulate the attic with his own hands, while saving a considerable amount of money that can be spent on much more interesting acquisitions for your country house.

If we talk about the insulation of the attic with their own hands in general, in all cases, the hydraulic and vaporizolizing material should be laid in obligatory. This is the basis, without which further work is meaningless. Then, as a rule, an adhesive is placed in which the insulation itself is mounted. How to maintain a comfortable temperature on the walls and floors in the house, with the help of fiberboard and drywall, you can read in the conclusion of our material.

Of course, all houses and roofs differ from each other - it is rare to meet several absolutely similar. But in all cases of arrangement of insulation, you will need to competently "bypass" all the irregularities and "underwater" construction stones: elements of rafters, beams and the design of the crate. Therefore, you will undoubtedly have to be pretty much and how to think about the action plan. It is for this reason that we advise you to think over the issue of insulation even at the time of construction of the house.

All private homes, as a rule, have a diverse, broken or trapezoid form, allowing ergonomically to use the attic space. For example, with bounce roofs, you can build additional by filling insulating material their cavities. Conduct global insulation activities is logical only if you intend to live in future attic. In the option, when this floor is planned to be made non-residential, like an attic, it will only be enough to insulate the floors - it will be quite enough for the insulation of non-residential premises, unless, of course, no one will stay out there.

Types of insulation

When choosing a insulation for the attic, you will need to answer two questions: What kind of construction is the roof of your home and in which climatic zone is the construction itself? Depending on this, you can establish certain insulation materials. What is the insulation for the attic to choose? How not to make a mistake in buying? It is impossible to say that the choice is so great that the eyes are missing, but it is still necessary to think about the choice in accordance with the desired characteristics. As a rule, according to the standard, mansard premises are insulated:

· Polyfoam;

· Polystyrethyrene;

· Minvata or glass coat;

· Equata;

· Polyurethane foam.

All these insulation have various properties and characteristics affecting the future to preserve heat in the house. Depending on the necessary exactly you will need to make a choice of insulation suitable in your home for a particular room.

For example, it is possible to insulate the roof of the attic from the inside with the help of foam. But this is a very expensive way, but absolutely does not use good reputation from the builders. The fact is that the foam is poorly misses moisture, and the liquid will begin to accumulate on the insulation, and this does not make this material and the effect from the insulation durable. To all, the peculiarity of the foam is subject to exposure to various deformations - one more minus in the piggy bank of the foam. So, when the rafter will begin in the construction, all sorts of cracks will appear in the layers of the insulation, through which cold air will penetrate into the house. Yes, and rodents, the insulation of the attic of the mansard foam clearly falls in taste: mice with a big hunt "try on the teeth" this material. In general, among the only plus - cheapness - a lot of minuses.

If we talk about polystyrene foam, he resembles the above-described insulation, but differs in the installation technique. Usually, polystyrene foam is put under rafters, so slots are formed on the tiles. The incomplete plus of this type of insulation is to similarly with, the details of which are attached to each other in the "grooves". This method of docking the details of the insulation makes it possible to create a smooth canvas, without gaps. This undoubtedly extends his life in comparison with foam, although not long.

A number of builders tends to choose the insulation of the attic of the attic from the inside of Minvata, when it comes to how to warm the attic. What are the advantages of this material? He is not a fuel, superbly keeps the heat, the liquid does not accumulate in the minvate, and its strength characteristics deserve all silence. Builders will very quickly lay this material, hiding his canvas in a special crate. Pluses are much more, with easier installation. So the insulation of the attic of the mansard of Minvata is not the worst way to keep the magnificent microclimate in the house.

Glasswater is something similar to Minvatu by the method of laying, but the first has a number of differences:

· Since the glass gambler includes very long fibers, it exceeds Minvatu in strength characteristics. All, glass gamble is better, perfectly retains heat and is characterized by excellent elasticity.

· Flakes are practically not hydrophobic.

In some cases, builders, arrangement of mansard insulation, resort to small tricks: they will install several types of materials at once. For example, rafting empties are filled with glass gambles, and on the roof itself laid polystyrene foam plates. This allows you to save money and maintain the quality of insulation.

The most expensive method of insulation of the attic from the inside with their own hands is the arrangement of the heat-insulating layers of Eco. How does this happen? Builders crushed wool, and the hose is blowing it into the rafter emptiness. Since paper includes paper, the material is distinguished by excellent indicators on environmental friendliness: almost the same as the real tree. And since the composition of EcoWhat includes a boor with antiseptic properties, the fungi and mold are not beginning to multiply in the insulation - one of the biggest problems country houses. The thermal insulation characteristics of this material are reminded by its qualities of glass gamble: a comfortable temperature is preserved in the house. It is important and the fact that for the entire use of the construction, you will not need to replace EcoWhat, because the latter does not settle and does not sit down, as it happens with cheaper insulation.

In the case of polyurethane foam, as a heater, everything is the "better". This material simply spare and, as you already understood, do not participate in the process, so work does not occupy a lot of time. Polyurethane Foolder makes great fills all the gaps, and its service life is calculated with decades. So with confidence you can say that it best insulation For attic.

We hope that after such a detailed briefing you no longer torment the question: "How to insulate the roof of the attic" and you have mastered the advantages and disadvantages of all kinds of materials used for this type of work. The choice, as before, remains for you - the type of insulation, its advantages and cons relative to each other.

How to insulate the attic minor

How to insulate the attic from the inside with their own hands? We will do it with the help of Minvati, having calculated the desired amount of material before installation.

So, prepare the necessary toolkit and do not forget to stock gloves, overalls and mask, because Minvata will dust.

You will use:

· Minvata;

· Hammer (for leaf alignment);

· Cyan, whitewash and chisel;

· Coupling from wood, nails and self-drawing;

· Ax and poberlem;

· Membrane, vaporizolation.

Since Minvat is usually stacked between the rafter, think in advance about the arrangement of waterproofing materials. To do this, you can use the waterproofing film, putting it from the bottom of the roof. The layers of the material must be over each other, and it should be fastened using adhesive tape. Put the film with a margin by the walls, slicing all the extra sections that will remain after the completion of the work.

Next, you should nourish the counterbask to the rafter elements. Between the plates, put the Minvatu so that it fits tightly to the rafters and did not form a slot. As you understand, in the process of laying insulation, with your own hands there is nothing complicated, it is worth only to want! We hope now it has become clear how to insulate the attic for winter accommodation.

Hansard insulation foamflast

If you have already covered the roof, or it is still open, it will be possible to insulate the attic with the help of foam. For this, as in the case of the Minvata, first of all, put the waterproofing film - it very effectively allows you to protect the place of work from unnecessary moisture. Well, if you enjoy the izospan with a membrane structure that allows the material to "breathe".

Put the layers of waterproofing on rafters, but do not pull the film. You can even mount the material so that it resulted a little. Unlock the isospan across the rafter elements, along the entire length of the roof. Keep track of which side you are placing the material: its water-repellent and the steamottopulating layer must be outside.

Next, put the film, overlooking it for ten centimeters, and suture with the tape. Leave the emptiness between the waterproofing and the crate, having a small bar, and putting the crate on it, followed by roofing.

Put the foam in the rafter emptiness, following the material to form the clearances. Polyfoam can be "fitting in size" using construction knife. Attach the insulation is better than glue or special specks - the latter will even more accurately fix the elements of the insulation.

Make sure that during the insulation of the attic of the attic with their own hands you have not formed the gaps in which the cold bridges may appear. If in the "Pie" will change dramatically temperature modeA condensate and roof will begin to reveal on the insulation. Therefore, it's good if you put the insulation with two layers of "rotary", as if bumping with sheets previous seams. Such a two-layer "Pie" should be copped with glue. This will exclude possible gaps and the risk of rotting will be minimal.

By the way, both in the case of installation of minvats and in the option of installing foam, you can put soundproofing materials that have a fibrous structure. Further, on the "Pie" to install a vapor barrier film (just as well, laying the bracket, and sinking the ribbon), attaching the material to the rafters by a construction stapler.

The skin is usually attached to the profile of wooden bars. This is done for reasons to ensure the ventilation properties of the roof (between the vaporizolizing layer and the trim). Well, if for this you will apply eco-friendly materials who know how to "breathe", because condensate will not be formed on them, which subsequently leads to rotting and rapid decomposition of materials.

When arranged on the roof of foam, do not forget to take care of and adjustable. If you forget about these items, in the rainy, the roof can be rejected. If this happens, your works will almost certainly go to the Nammark. We hope that you concluded that the unprofessional will cope with these works, and you will no longer break your head, thinking about the question: "How to insulate the attic from the inside"?

Insulation with covered roof

What to deal with the insulation of the attic from the inside if the roof is already covered? In this embodiment, you should think about the inner cover of the floor. You will also get to produce this species work with your own hands. It is possible to do this by using gypsum or fiberboard. Undoubtedly, if you have never been engaged in such work, it is better to study video materials in advance: then you will clearly understand for yourself what and how to do. Do not rely on "Avos" and hope that you will succeed from the first time without the help of professionals.

Everyone knows that gyroxes attached to metal profiles, to whose selection should be approached with all thoroughness. Place such guides at a distance of 50 cm from each other, using the level. Plasterboard can be attached to profiles using self-tapping screws. But do not forget to put under the metroproporophilic design of the hydrotreating film. And when the gyroxes and the film will be installed, separate or color plasterboard. Undoubtedly, the front of work in this type of insulation will be quite large. But if you're in advance "cuddle in the question", then, undoubtedly, cope with the task for a fairly short time.

In the second embodiment of the attic of the attic with the "finished" roof, you can apply the Fiberboard. This material is easier to install, rather than gyps. To all, the Fiberboard is inexpensive, it is distinguished by a slight weight and excellently isolates the sounds. If we talk about the finish finish, on the sheets of the Fiberboard perfectly fall as wallpaper and a number of other materials.
Just reveal the DVP knife and attach to the crate, with the help of dowels or self-tapping screws. The undoubted advantage of the Fiberboard is denoted by the fact that you and alone can cope with the entire front of the work on the insulation of the attic with a covered roof.

Well, when you warm the walls on the floor, do not forget to take care of the floors: to put the rubberoid, or the substrate, and stack the design of the Fiberboard. Only then on the insulated "pie" can be putting the finish coating.

Summing up our story about the insulation of the attic floor, we note that this is not an excessive task. Such work will be simple and easily performed if you carefully read the article, and took note of all our leaders. Do not be afraid to change something for the better something in your environment, and let the attic of the cold and dummy, thanks to your efforts, will turn into a cozy, having homemade floor.

Hansard insulation. Video

Mansards are most often equipped for additional residential space. At the same time, it is not necessary to live in the attic - all work on the insulation of the upper room are carried out with the calculation of the high-quality thermal insulation of the house in order to save energy resources. In addition, being on warm attic is much more comfortable than in a displeased room.

Features

Residential attic - no longer a rare phenomenon during the construction of a private house in two floors. More and more attention is paid to the functional qualities of each centimeter of the attic area. Therefore, it is important to repair or make a project at home so that if necessary, individual rooms can be involved, make them functional and more suitable for living. In order to feel warm and cozy under the roof at any time of the year, work on insulation, taking into account the features of the attic. For example, a special insulation matters when the roof is already covered.

There are certain norms of such works from the inside in the attic room under the finished roof.It is necessary to take into account that attic as such is not equivalent to the attic room. Attic always has a characteristic bias, and the highest point of height is usually at the level of 2.5 m. For thermal insulation of such a room, various materials can be used. From the most common can be called mineral wool and foam. When carrying out work on the insulation of the attic, it is necessary to consider what the room will be appearancewhether it will lose "extra" meters.

For high-quality insulation of the attic from the inside, if the roof is already covered, the chosen technology is important. So, with the insulation of the walls and the ceiling, one or another method of work is used. For example, a multilayer structure is used for the insulation of the roof of the attic (for example, in 5 layers of the glue for foam).

All work in interior decoration Mansards for the purpose of insulation are carried out at five stages.

• Roofing is insulated, a rafter system is processed.Springs from a wooden bar can be seen under the roof of houses, erected by old construction technologies. Usually, the roof of such houses covers tiles or slate. Materials are distinguished by very high thermal conductivity. In such cases, it is said that the roof is simply protected from wind and external weather influences.

• Waterproofing quality - Another important criterion for ensuring the reliability of the roofing design as a whole. Waterproofing is simply necessary in the attic room. For this purpose, membrane films are usually used, which can pass steam, but do not let moisture. In old houses, it is often possible to see a simple rubberoid with similar properties instead of a special film. The main feature of insulating materials is the optimal protection of the roof at the joints, the prevention of moisture in the heat insulation material. Waterproofing coatings today differ in steaming.
• Warming materials.Of the modern means, those are characterized by low thermal conductivity are used. The parameters of the insulation between 0.03-0.04 W / MK in quality and resistance are comparable with reinforced polyfoam. Minvata or extruded polystyrene foam (Penoplex, Penosole) are also actively used to insulate the attic from the inside. In terms of efficiency, the Penoplex is assessed above the others, but it is more expensive. The selected materials must meet the main requirements - ensure heat exchange in winter, to protect against overheating in the summer.

• Parosolation materials.Usually we are talking about a membrane film that will help preserve the initial properties of the insulation. The material should not provoke condensate formation, which is a misfortune for thermal insulation materials.
• Decorative properties. Insulated attic must meet the requirements of the design of the room, comply with the general concept designer design houses. Therefore, the facing is paid so much attention. As a decorative finish, drywall, OSB plates or other varieties of materials, which can also be used on the ceiling, and on the walls and on the floor of the attic.

Roof designs

The reliability of the house is determined by the roofing design. The roof can be double, broken, distinguish a slope. Due to the design features of the attic, it is possible to get an additional useful area. To do this, it is necessary to competently dispose of the attic space of the house, especially for low-rise buildings. An important role in this case is given to the characteristics of the roof. Traditionally, pentagonal duplex structures with a slope of different magnitude were suitable for organizing the attic room. A convex break on such roofs was formed due to the difference in slopes.

Many schemes country houses Complies with the definitions of the "broken" roof. Today, the configuration of such attic roofs has undergone a lot of modifications. Now it is not only a pentagon and not only a bartal roof. But their main technological features persist.

Externally, it is possible to evaluate the shape of the attic design by several parameters.

On the slope and roof configuration:

• the roof of the triangular view with a multi-level slope of the lower and top part in the form of a bantle facility without fractures;
• pentagonal variations on the topic of roofs with rods on convex angles (two docked parts are vividly identified in the design).

At the mansard roofs a multi-tier rafting system. In the lower tier there is a useful area with a height of 2-2.5 m (the scheme is preparing preparing). Height parameters are indicated for the convenience of moving inside. The second tier is the form of the top of the roof, which can have arbitrary height. Although here you can experiment with a height to get the optimally comfortable shape of the roof. In this aspect it is more profitable to use a pentagonal attic, in which the corners as it were for the imaginary circumference. It is worth considering that the attic can be equipped not only in the presence of a bartal roof. Using basic technologies, it is possible to arrange and insulate the attic in single-table or tent roof structures.

So, the main feature of the attic roof should be recognized by two adjacent rafting structures, which are connected to the triangle or pentagon, thereby creating the desired shape of the roof of the house.

The main technologies of the device of the pitched roof, known to date.

• Inclined. The bottom tier of the attic is built, then the upper part is placed.
• Hanging.Depending on the technical features Roofing design is equipped with top. In case of a schematic section of the attic roof, it can be noted that below it looks like a trapeze, and on top - on a triangle.

If nothing needs to be done with the attic of the attic, then you can proceed directly to the work on the insulation of the room from the inside, by choosing the right quality material.

Types of insulation

Selecting the best insulation for attic, the main characteristics of the material should be taken into account, its valuable properties, pros and cons for a particular structure.

As the main criteria for the selection of the insulation, it is worth highlighting the following:

• good thermal insulation (for example, foil material, insulation of mining, expanded polystyrene, basalt material);
• economical use (rational insulation);

• strength and durability;
• moisture-repellent properties;
• noise insulation;
• convenience of laying.

It is important to remember that its ability to maintain heat will be the main value of the material, that is, the thermal conductivity of thermal insulation materials.

The insulation that has the thermal conductivity indicator of the thermal conductivity below, has better qualities. For example, less than 0.04 W / ms. This is taking into account the thickness of the material and climatic conditions. There is still a question about the possibility of using the same heat insulating material for lining of walls and floors. More universal material quality makes it possible to work on any coating (walls, floors, ceiling). Usually, the walls and floors and floors are usually "wrapped". This allows you to achieve insulation to the same extent all over the perimeter of the room.

When choosing insulation, you cannot forget about the sound-absorbing properties of the material. To understand this issue, it is worth introducing noise on a steel roof even from a small rain, especially when it comes to residential attic. Calm and comfort are essential criteria for home improvement. Also when choosing a insulation must be checked carrying constructionFrom which materials it is made (metal, wood, reinforced concrete). Combustible materials (rafters) will not allow the use of some types of insulation. But, mostly, secure and eco-friendly are used today. facing materials. Among them, there are both traditional (glasswalk) and more technological (eclaw, foil plate). Consider some of them.

Plates and mats

For internal insulation Mansardes in the presence of roofs are used such fireproof and moisture-repellent materials such as mineral wool, glass gamble, eco-plastic, foam, foam, foam cake with sawdust, extruded polystyrene foam. Insulated material in the form of plates and mats is suitable for single or multicate roofs. The doom is made by a similar scheme. Plates are convenient when transporting and mounting.

Rolled

Many more convenient to use materials in rolls. You can easily cut off a piece of the desired length. Rolled insulation from traditional materials are suitable for roofs that have rafters are at a standard distance from each other. If necessary, the material you can fill out the remaining free space.

Sprayed

The so-called sprayed materials for the cladding of the attic leave no junctions and sections for the penetration of the cold. For example, you can use the method of spraying polyurethane foam. For such insulation, no preliminary training is required. The material is simply poured on a certain thickness (usually on the thickness of the rafter). These materials are distinguished by the fact that they are resistant to the development of fungus and mold. The spraying is conveniently carried out both on the walls and the ceiling.

How to choose?

The quality and durability of the material depends on the manufacturer, operating conditions and on the characteristics of the material. The insulation must be maximum resistant to mechanical loads, so it is always worth choosing the one that is better in specific indicators. The construction market today replete with modern insulation of different brands, characterized by weight, color, installation features.

A small mass of the insulation allows it to be used between the attic structures of the attic. With a more durable frame, it is possible to use and more hard material (plates). They are mounted on the crate or on the rafter design. Depending on the frequent load on the roof (snow), you can decide on a soft or rigid insulation. Too soft will have to repair. Necessary hard can lose in thermal insulation properties, for example, with ceiling thermal insulation. And, of course, insulated material for the attic should not crack, deform or modify. It is not always possible to determine the choice of material for the insulation of the attic of the attic from the inside, even when it does not need to cover the roof.

All thermal insulation materials have their advantages and disadvantages. Having unique characteristicsSuch materials are evaluated by universal features.

• Even a budget option Insulation (for example, foam) must maintain heat in the house. Therefore, it is necessary to use the material with a thickness of at least 10 cm. The plates from the same foam of almost weightless, special installation is not required, suitable for attic space of any type. However, the foam is easily burning. Therefore, when choosing a insulation, you should not always give preference to cheap analogs.
• Extruded expanded polystyrene can be used as insulation both inside and outside the room. No need to confuse it with foam, the latter has another structure. Polystyrene foam does not respond to chemical reagents, it is distinguished by low heat-conductivity, does not absorb moisture. Material plates may have different density, but they are able to deform much.

• The foam is used as a more modern means as a heater, but also more expensive. The insulation in the form of a roll material can easily replace mineral wool. It does not affect moisture. It is believed that this material has properties capable of protecting from radioactive waves.
• Spraying liquid polyurethane foam will make it possible to achieve the necessary resistance to drafts. Rather, they will not be, since the insulation can be closed joints and gaps on any surface. When using the material, there is no need for additional laying of the heat-insulating material.

• Equodata for attic is used relatively recently. This material consists by 80 percent of cellulose. The rest is antiseptic additives. When used, the eco-paper takes into account the shrinkage of the material during operation. Modern material is resistant to ignition, not subject to wetting, does not collect bacteria.
• Mineral wool we have covered almost all the attic designs of country houses. This material is very popular due to the quality of heat and sound insulation. You can lay on the crate or on the frame. Minvat is not subject to rot, but it must be remembered that the material is able to absorb moisture and due to this increase in size. And this gives extra design weight.

Calculation of thickness

Material with universal parameters - modern insulationIt allows you to create at the top of the house the most comfortable conditions and the desired microclimate protecting against heat loss. Installation of the insulation depends on its technical characteristics. Consumption is determined by its thickness. there is different variants Montage, because in the construction business today is used almost everything - from mineral wool to foam. Calculate the desired thickness of the insulation material can be calculated according to a specific scheme and based on the main parameters of SNiP. Computing the thickness, the masters are focused on regulatory requirements. The characteristics of both the thermal insulator and the attic design are also taken into account.

Rules for calculations.

• When choosing a insulation for the attic room, the production density of the material is taken into account. The thermal insulator is selected in such a way as to ensure the general thermal conductivity of wall materials.

• A load indicator should be taken into account when installing insulation. The heat insulating materials differ in weight - it is greater with a greater density of the insulator. So, if the design is stone or made of bricks, this will allow you to use any facing material. For wooden carcass Suitable thermal density insulation.
• Definition of dew point. According to this parameter, when calculating the selection of the thermal insulator, the quality of wall decoration both inside and outside is taken into account. The presence of dense plaster, for example, allows you to "save" on the insulation. The insulation incorrectly chosen in thickness will lead to condensate accumulation, which will negatively affect the operational characteristics of the entire structure.

• P - indicator of material thickness;
• K is the value of the coefficient of thermal conductivity.

Many owners of old houses are thinking about the expansion of living space due to the attic. However, they immediately wonder how to be, if the roof is already covered, and the mansard is still needed. In this case, the rescue comes to carry out insulation from the inside.

Features

The process of insulation of the attic from the inside cannot be called easy. To do this, you need to know the specifics of the roofing device, as well as figure out whether your existing roof is suitable for insulation. Indeed, not every attic can be converted under athenium square, especially if the roof is already covered.

There are three situations as the roof can be performed:

• There is only ventilation gap between rafters and the crate. In this case, the roof is considered absolutely unsuitable for insulation. We'll have to fully disassemble roofing designto insulate it.
• A polyethylene film is laid between the crate and rafters, which performs the role of vapor barrier. Such decisions can be considered optimal, and the roof is fully prepared for subsequent work on its insulation.
• Diffusion membrane is laid between the rafters and the crate. An option similar to the previous one. The presence of a waterproofing layer is evidence that the roof is prepared for insulation from the inside.

Thus, the main feature is the preparedness of the roof to further insulation.

Insulation

The thermal insulation of the roof of a private house, cottage, cottage can be performed using different means. Here is I. liquid materials, and elastic, and even those that have a relatively high density.

Before you start choosing, be sure to pay attention to the roof design. It often happens that not every material is universal, so it is better to be restrained. The simplest example is the insulation of a duplex and broken roofs: if almost any insulation will be suitable for a simple double design, then for broken - not all.

If you do not consider liquid insulation, the rest are sold in two forms - in the plates and in rolls. As you can guess, tight insulation are presented in the stoves, in rolls - fibrous.

It should be noted that not all available options are suitable for insulation. This is due to the fact that insulation the attic from the inside is much more complicated due to the already existing rafters. This increases the need for the leveling of cold bridges.

Materials should be considered for internal thermal insulation in more detail.

Styrofoam

Ordinary foam applies to the cheapest materials. It is sold by finished plates, which makes it comfortable in work. Despite the fact that the foam applies to budget thermal insulating solutions, it has many advantages.

So, the foam is not hygroscopic - it absolutely does not absorb water and moisture. To increase water-repellent characteristics, it suffices to process it with a specialwhich breaks down the pores on the surface, and water will simply flush along foam plates.

It should be borne in mind that the foam has a very low weight due to the presence of a large number of emptiness between the granules, its constituents. This contributes to the fact that with insulation works can be cope and alone. Easyness gives another advantage that consists in facilitating the load on the roof design.

The foam is poorly conducted, as a result, it can be safely argued that it is perfectly isolating the attic. The simplicity of work with it is another significant advantage of the material: cutting the material, cutting pieces of the desired size, can be an ordinary stationery knife.

However, there are some drawbacks here. First, the foam does not "breathe at all," because of which condensate can be formed. Secondly, the foam is affected by pests, in particular, rodents. Thirdly, polyfoam can not make wooden floors, Since over time the tree will give shrinkage, and gaps will appear between foam plates.

About how to insulate the attic foam, told in the next video.

Penosop

Penosole, or carbamy-formaldehyde foam, is a liquid foam option. A warming solution is prepared immediately before use. His difference from many other mounting compositions, for example, PPU foam, is that in the process of frosting it does not expand, while maintaining the source and condition.

The mass resembles a white foam, similar to the form with shaving foam.

Liquid foam plastic is often used to insulate roofing and mansard at the construction stage, but can be applied after the roof is laid. Among other things, it can be additionally insulated with the walls and the floor of the attic room.

The vapor permeability of the material, like a dense analog, is almost at zero, which makes the obligatory care of the decent ventilation of the roof. However, the material does not heat heat, so with its main function - heat-insulating - copes perfectly. So if you perform all the work in a manner, thermal insulation with foamizol will become a worthy and budget solution.

Extruded polystyrene foam or penplex

Despite the fact that the foam and expanded polystyrene belong to the same group, the second is more practical. This is largely due to the specifics of the installation. So, polystyrene foam closes rafters, which is why the best tightness is achieved. The polystyrene foambilities are easily fixed with the help of glue. Because of the low weight, installation can be made independently.

The material has a long service life, while it does not rot and is not subjected to attacks from rodents. The only serious drawback is a flammability of the material. Will have to take care of the additional insulation of the wiringAfter all, one spark is capable of leading a strong fire.

If you do not provide any communications in the attic, expanded in a great choice, especially if we consider that it can be coated any finishing material. It is also compatible with wood, and with metal, and with any roofing coatings.

Minvata.

Mineral wool often acts as an alternative to Polymplia. This material refers to a roller, which is caused by the convenience of laying thermal insulators supplied in this way. Minvata has a fibrous structure that has a fundamentally affects some of its properties.

So, mineral wool - elastic material, which is attached between rafters. At the same time, additional fasteners will not be required, it is enough just to cut the plates from the wool for 2-3 cm wider than the portal in which the insulation will be inserted.

Rodents do not attempt onto cotton, so you can not worry about the integrity of the insulation layer. Mineral wool, however, refers to the category of eco-friendly insulation. Among other things, it guarantees excellent thermal insulation, despite the fact that it does not absorb moisture, and even wet, it will dry in record short time. Also, the fibrous material is better to use if it is necessary to additionally sound the attic of the attic from the surrounding street noises.

For details on the insulation of the attic of the Minskoye Minskoy in the next video.

Glasswater

Glasswater is one of the varieties of mineral wool, but the difference is obvious. First of all, it is worth noting that the materials are made from different fibers. It uses fiberglass. Due to this, the material is more elastic and durable. In addition, glass gamble has better noise absorbing characteristics. At the same time, it hydrophobic - well absorbs moisture, but does not dry out, as a result of which, when wetting, it quickly loses its operational properties.

Many are afraid that the use of glass gambles in thermal insulation purposes within the residential premises will lead to detrimental consequences. In fact, it is not. If you correctly spend everything finishing workThere will be no harm to health. On the contrary, glass gamble is even more secure than the penurex because it does not burn.

However, the material requires accuracy when it is laying. It will be necessary to take all security measures by protecting against glass dust organs of vision, respiratory tract and skin.

Stone Vata.

Among all the insulation wats, Stone is more expensive than analogues, and all due to its special properties. Compared to others, it itself is safe and practically devoid of disadvantages inherent in other samples. It is the most ecologically clean of all, not afraid of elevated temperatures, as it does not ignite, and also not deformed under the influence of heat.

Stone wool delays everything perfectly outsided soundsAt the same time, its sound-absorbing characteristics are much higher than that of the other WAT. Another advantage is good vapor permeability of the material. He "breathes", so the condensate cannot be formed on it.

Stone wool is able to serve for a long time. Such good performance properties are due not only to the strength properties of the material, but also its ability to resist mechanical impacts. Even if it is compressed, it is not deformed.

Vata is sold in the form of soft plates that can be easily cut into the necessary formats if necessary. The only existing drawback is a high price, but the material is worth their money.

Ekwata.

Equata is very different from other WAT form of sale. If the remaining analogues are supplied in rolls or stoves, then the eco-house is first crushed, and then applied by scattering the material using special equipment. It is believed that it is better to build all the existing slits, forming a monolithic insulating coating.

Disadvantages here are two. First, you need to apply eco with special tools. Secondly, the value of the material also can not be called a democratic.

Polyurene Foolder

Foamed polyurethane foam also need to be applied using special devices that cost quite expensive.

To avoid unprofitable shopping, it is easier to make equipment into leasing - rent.

The use of equipment and the application itself is quite complex, so when working with the material it is necessary to have at least some experience and knowledge on this issue.

Polyuretoloretan is most similar to the mounting foam, since it has a similar principle of operation. It is also expanding the same when frozen, completely closing all the gaps and gaps, through which the cold wind can penetrate or get the precious warmth. After pouring, the material becomes monolithic and smooth. This feature testifies that it does not absorb moisture, therefore it is possible to do without the construction of additional hydro and vapor insulation layers.

All this makes foamed polyurethane foam perfect choice, regardless of which the material is made of roofing and overlap. Optimal solution When working with him - invite the team of specialistswho will run laying in a few hours on their equipment, making everything in compliance with technology.

Penophol

Penofol is the only one in its kind foil insulation. It is produced in the form of plates of foamed polyethylene, with one or two sides of the aluminum layer coated. Aluminum reflects heat returning it back to the room, so heat loss is minimized.

However, it is important to monitor when laying so that the foil side is deployed inside the room, and not outward.

Penofol is absolutely safe for humans and animals, although not natural material. Thanks to the aluminum coating, it does not heat it, which gives reason to approve the excellent thermal insulation properties of the material. Among other things, making vaporizolation for this material may not need to be, since proper montage It copes perfectly with vapor barrier thanks to the special texture.

If planned to operate the attic for permanent residence, I choose a foam, you will not regret.

Preparation of the room

Deciding to warm the attic from the inside, first need to properly prepare the premises for work. Keep in mind that not every attic is suitable for insulation. Check whether the height of the ceilings is 2.5 m more than 50% of the entire attic area. If not, it is not necessary to engage in insulation - still it will be impossible to live here.

Next, dismantle the entire existing trimming material, exposing rafters. Installation of the insulation will be made or on top of them either between them. Check the condition of the roof, as well as the presence of steam and waterproofing layers. Keep in mind that the roofing of the leaks must first be corrected, and only after that you can move towards insulation.

It is important that they are in good condition, did not have slits, except for ventilation.

Parosolation

Creating an attic floor for winter accommodation, especially if winter in your area is severe, it is necessary to first check the presence of vaporizolation. As a rule, it is done immediately when the roof is mounted, even if they do not even plan to use the space under it as an extra room. If there are no vaporizolation, then the roof will have to redo the outside, disassembling the roofing materials. Make a vapor insulation layer from the inside, alas, it is impossible, because it must lie between the rafters and the counterclaim.

To create vaporizolation can be used various materials. All of them have their own advantages and disadvantages, as well as the specifics of combinations with insulating materials. All this must be borne in mind, moving towards insulation, therefore it makes sense to stop on materials for vapor barrier in more detail.

In addition, it will help you decide on the choice if the roof of your home has no vaporizolation layer.

Polyethylene film

Despite the cheapness of the material, many builders strongly recommend using it. This is due to the fact that it is unsuitable for creating a vapor insulating layer in Russian realities. The material is absolutely not "breathing": He does not miss not only moisture, but also air, and it creates problems with circulation and, accordingly, the greenhouse effect. So, condensate cannot evaporate and, staining, gets into thermal insulation.

Therefore, if in your home vaporizolation is still made using a plastic film, refuse to purchase insulation absorbent water, for example, glass gambles.

Over time, the film has a property to collapse and crack, so after a short period of time you will still have to fully disassemble everything to replace your fragile material.

Pergamine

Pergamine is suitable for vapor, and for waterproofing, so he received universal recognition. However, act here will be in two directions. First, the pergamine layer will need to be paved between the roof and the counterclaim, and secondly - on the insulation from the room. If all work is performed correctly, it guarantees reliable protection and optimal microclimate on the attic. From above, between roofing and a counterclaim must be laid double layer of pergamine. Only then can be achieved optimal effect.

Pergamine is more needed to protect the insulation from moisture, therefore anyone can be selected as a heating material. Try to choose such options that are not deformed under the influence of temperature drops, and are also not affected by rodents. Excellent suitable as cotton variants and penplex.

Ruberoid

Ruberoid is used as a vaporizolator since the time of the USSR, so in old houses you can find exactly such a material between the roof and rafters. However, if possible, such a layer will need to dismantle. This is due to the fact that Ruberoid - the material is rotting, and in accordance with the norms it can not be used for hydro and vaporizolation in buildings with a long service life.

If Ruberoid is decided to leave, then you should not wait for it good parosolation qualities. For this better to pave an additional layer of special vapor barrier material, at least the same polyethylene film.

It should be borne in mind that condensate can accumulate on the front roofing side, which will lead to the wetting of the insulation. So, if insulation is temporary in nature (for example, it is carried out in winter, and in the spring it is planned to remake everything), then the reference can be combined with the refoilt.

Izospan

The material of the isospan consists of polypropylene. It refers to the most recommended vapor barrierdue to the fact that it was developed only for these purposes.

The Izospan collects condensate and in the future does not give him to fall on the insulation. For this corresponds to the two-way texture of the material. On the one hand he is smooth, and on the other - a little rough. On the rough side, the droplets of condensate are delayed and evaporated. With the help of Isyospan, not only the roof, but also the walls of the attic.

Depending on the properties of the isyospan, marks differ. The most expensive but also effective materials are considered to effect Energy Saving Energy Saving FB, FS, FD, FX. They have a foil coating that reflects heat back to the room, thereby bringing the heat loss almost no. In this case, the special texture still does not allow condensate to roll and spoil the insulation.

Waterproofing membrane

It is not necessary to attribute by waterproofing membranes all the same properties that are inherent in specialized vapor barrier films. Indeed, those and others collect and evaporate condensate, but the main task of waterproofing membranes is the protection of the house from moisture, and not from steam. In addition, waterproofing membranes have a wider range of applications: from insulation of attic and basements before the protection of the pools.

Waterproofing membranes are available in different kinds. There is a diffusion, superdiffusion, as well as anti-condensate, which is more suitable for a vaporizolizing role. If you have discovered, breaking the trim material, one of these membranes, consider that you are big lucky.

You can lay any insulation, without fear that it will get into and quickly lose its qualities. In addition, the microclimate on the attic will be excellent.

Penophol

Penofol is both insulating and vapor insulation material. However, it is possible to lay it only when a hydroxlamation membrane has been found between the roof and rafters.

The reflecting foil surface in itself will collect condensate and will help his evaporation, but the second "naked" side must be well protected from moisture. Only in this case the type will cope with steam, and with thermal insulation.

Flow consumption

The calculation of the material is made even at the stage of viewing the roof for damage. It is important to take into account the step between the rafters and the distance between vaporizoation and the inner space. The amount and thickness of the plates depend on the inner space: whether the heat insulation is laid in one layer or in several. The size of the plates depends on the distances between the rafters.

Please note that if the step between the rafters is more than 60 cm, then it will be necessary to independently prepare an additional crate to make the fastening of thermal insulation possible.

As for the sprayed insulation, then in this case it will be necessary to calculate the volume. Previously, it will be necessary to clarify such data as the intended thickness of the heat-insulating layer, the perimeter of the rooms and the height of the walls, as well as the density of the insulation. We must not forget about the availability of windows and doors. It is best to use a special calculator.

Solar scheme

Since the roof is mainly insulated when the roof is insulated mainly, it makes sense to consider the layering scheme only for it.

If you start outside, the cake will look like this:

• From above is located roofing materialthat does not touch. Under it is a doom and a counterbasket that serve as a frame.
• Next proceeds by a layer of hydro and vaporizolation, which is also the initial one.
• Under the waterproofing is laid out a layer of insulation. Depending on the width of the step between the rafters, an additional doom can be constructed here.
• From the side of the room, a vapor insulation layer that protects the insulation is attached.
• In conclusion, finish finish.

How to insulate with your own hands?

To insulate the attic with their own hands from the inside, you need to keep in mind the layout plan for each other, as well as follow the next step-by-step instruction:

• From the existing waterproofing layer, it is necessary to retreat a little, leaving the air opening. This will allow the insulation to "breathe".
• After that, the insulation is mounted. Depending on the material, it can be laid between rafters or on them, as well as spray. How to handle with one or another insulation material is written in the manual for it.
• Next set a vapor barrier film. If the gap between it and the insulation is possible, then the adjoining to the walls, the ceiling and in the case of the attic to the floor should be sealed. Otherwise, condensate will be formed on the side of the film, which is deployed to the insulation, and so should not be.
• In the last stage produced finish finish. You can choose from a variety of options, however, they usually acquire plasterboard, lining or MDF plates.

• wadding insulation is better to buy not in rolls, but in mats, so they will not need to be time for "departing";
• for floor insulation, you need to choose a foam or other inexpensive material;
• the insulation does not need additional consolidation, however, if that, for this you can use nails, adhesive tape or construction stapler.

The roof is one of the most important structural elements of the building. It is exposed to a variety of environmental factors. Protects the house from high and low temperatures, atmospheric precipitation, solar radiation. If the roof is not insulated in accordance with the construction norms, heat loss through the roof can reach a third of the total heat loss at home. The insulation of the attic roof is not such a simple process as it may seem, although with your own hands. If your house has an attic floor, the question will inevitably arise how to insulate the roof. Many owners prefer to make an extra room there. First, it increases the overall residential area of \u200b\u200bthe house. And secondly, a new original room appears. During the construction of modern cottage villages, the attic rooms are planned initially. But in old houses you can easily remake the attic with your own hands in the residential premises.

Insulating material used for the attic roof, in addition to preserving heat in the house protects against acoustic oscillations. Therefore, it is important to solve, the better to insulate mansard roof.

First you need to decide how to insulate the roof of your attic. To date, there are many options for thermal insulation materials. Installation of them easy to make with your own hands.

The thermal insulation should contribute to the preservation of a favorable atmosphere indoors. In winter, warmth, and in the summer - coolness should be maintained.

There are many nuances in the installation of the roof itself. The walls of the attic room are either the frontmostones of the building or rods, or adjacent to the skates. That is why the intensive movement of air begins through the roof. Because of what it is constantly subjected to temperature drops. To avoid the above problem, the insulation of the attic must be carried out in the sequence (from the inner layer to the outer layer):

1. Steam insulating layer.
2. Heat insulating layer.
3. Ventilation gap.
4. Waterproofing layer.
5. Directly roofing material.

If a high-quality insulation of the attic roof is performed, then the absence of the above layers is not recommended. It is especially worth noting the role of the heat insulating layer and the ventilation gap. It is due to the presence of all messages that the microclimate in the attic room is provided.

What is worth paying attention to when choosing insulation

When choosing a heater, it is worth a thermal conductivity at first. This is the ability to give and absorb the heat between the sacrifice space and the ambient air. Material is desirable with low thermal conductivity. First, it contributes to the best protection of the house from heat leaks. And secondly, a thin layer of heat insulating material will be required.

Properly insulated mansard

On the other hand, if there is insufficient insulation of the attic roof, the problems begin in the winter. AT winter months The roof is covered with a layer of snow. Snow is a good additional heat insulating layer. But with insufficient insulation, it is covered with its own hands through the roof. Snow is gradually melting. The layer of ice is formed. Loda is not able to maintain heat. It has a mechanical impact on the design. Including the outer coating of the roof. This leads to its wear and gradual destruction. Sometimes because of this it is required after each winter to repair the outer roofing layer. With sufficient heat insulation, the snow does not melt in winter and does not turn into ice. The roof retains its design, and the snow provides additional protection against heat loss. Summer the situation is reverse. Under the influence of direct solar radiation, the roof is inclined to heat up and a suffocating atmosphere is created. If you lay a layer of insulation in sufficient quantities, this problem will not be a comfortable environment in the attic.

The main characteristics of insulation

When solving the question of how to insulate the roof of the attic home from the inside, in addition to thermal conductivity, it is necessary to pay attention to several more important parameters of the insulating material. The most important features:

• waterproofing;
• weight;
• fire safety;
• durability;
• material thickness;
• environmental characteristics;
• terms of use.

Resistance to moisture is usually indicated by a manufacturer of a particular material. It is an important parameter, since the roof can give to flow and wet. Therefore, it is desirable to choose a material with water-repellent properties. If this is not available for any other reason, the layer will have to be additionally hydroizing. Also has great importance Weight material. What he is less, the better. The total weight of the material is determined based on its relative density. Mineral wool materials should be with a density of 45 to 50 kg / meter cube. When using fiberglass, the density should be within 20 kg / meter cube. Higher materials will have excessive pressure on the design.

Insulating layers must be non-flammable. This is usually reflected in the technical documentation. As for durability, the ability of the insulation for many years to maintain its form is important. After all, the roof can be multigid. If the insulation is deformed, the roof will simply lose its protective properties.

What materials are popular

It is necessary to disassemble each separately to decide how to properly insulate the roof of the attic. Main materials:

• styrofoam;
• extruded polystyrene foam;
• polyurethane foam;
• mineral wool;
• glasswater.

The better to insulate the roof, solve you. But before that, you need to get acquainted with each material.

Styrofoam - This is a sought-after material among people, in front of which the problem is worth how to insulate the roof. It has a suitable thermal conductivity, low density and, accordingly, a small weight. Polyfoam provides good protection against water, it is quite inexpensive. On the other hand, it has certain disadvantages. Its main minus is insufficient fire safety. Also when installing with your own hands, it often crumbs. As a result, gaps between rafters appear. This in turn leads to a decrease in the thermal insulation characteristics of the coating. Another foam has a short service life.

Extruded expanded polystyrene foam It has better characteristics. First, non-combustible and ensures the necessary fire safety. It does not crumble over time. It has water-repellent properties. The plus is also something that needs a very thin layer of material. Material is not recommended to warm living spaces.

Polyurene Foolder It differs from previous options by laying. Thanks to this, there are no cracks. The material perfectly retains the form. It has the necessary fire safety and pushes moisture. The disadvantage of polyurethane foam is considered a bad ability to skip pairs. Because of this, in the attic room there may be increased humidity. The problem is solved by the organization of adequate ventilation.

Mineral Wool and Glasswater Widely known as insulation materials. Have a lot of advantages. Excellent fire safety, well kept heat, have a low density. Do not leave gaps and gaps when laying. The material provides excellent noise insulation, has a low price. The minuses include high moisture content and fervor.

Important: Installation of glass gambles are carried out in closed clothing, mask and gloves. Contact of particles of material with leather and mucous membranes should be avoided.

Laying of thermal insulation material

With the insulation of the attic do not forget about hydro and vaporizolation

After selection of the material, it is necessary to prepare the room to install. The insulation of the roof of the attic begin with determining the step laying the insulation. We must try so that the sheets of the insulation are closely taken between the roof rafters. This will avoid the formation of gaps and further heat loss. If you are using foam, then this nuance does not matter for you. Waterproofing is placed in a mustache between rafters and a doom. Then, with the help of screws, wooden panels that provide ventilation are installed. The insulating material itself is mounted on the created platform between the rafter.

Tip: rafters themselves misses heat. It is necessary to put an additional thin layer of insulating material from above. Be sure to remember the location of the rafter.

This will be useful when attaching a variety of designs in the attic room.

Video: Brief theses of the correct thermal insulation of the mineral wool insulation

Thus, insulation the roof is absolutely not difficult. To do this, you need to pick up suitable materialwho satisfies you. And then according to technology, mount the insulation. As a result, a favorable climate for living will be created in the attic room.

Today is not uncommon. Increase the attic useful square meters - The easiest way. But in order for throughout the year, the roof will have to insulate. Therefore, in this article, we consider how the insulation of the attic is carried out from the inside if the roof is already covered with roofing material. We will understand which thermal insulation materials can be used for this and what technologies to take advantage.

And although many believe that attic is a kind of attic, in fact, this is a completely different room, which differs from the first size. And the main height of them. It must be at least 2.5 m.

In all the rest, this is an attic space that fenced with a rafter system with laid on it. If the roof is duple, then from both sides, the attitudes protect the frontones - vertical walls that support the rafter design. It is in them that do the doors with access to the adjacent balcony. But the main walls of the room is the roof of the house with a certain slope slope.

The technology of assembling the rafter system and roofing material is that it is necessarily placed in between them wooden designs From unexpected leaks from roofing. This is a kind of substituhance. On the roofs are mainly used waterproofing material Rolled type, which strips from the eaves to the skate stacked with overlap in the size of 20-30 cm and fastening to the rafter feet. The film is stacked with a small check in the case of temperature tension or expansion, plus the entire edge of the adjacent bands are necessarily fasten with a scotch or self-adhesive tape.

Then, along the rafted, wooden rails are stuffed, which are called a counterclaim, and the transverse rails that bear the name are mounted on them. For the last and stacked roofing material with fastening.

The view from the inside of the attic is the rafting legs covered on top of the waterproofing layer. This is this design and will have to. The question is how to warm the attic from the inside with their own hands, we emphasize - with your own hands - requires first of all the definition of the insulation, or rather, its choice. Because not all modern thermal insulation materials can be used independently. But we will deal with everyone, and be sure to designate the best of them.

Heat roof insulation

It should be noted that the slope of the slopes determining the walls of the attic, this is a cellular design formed by rapid legs. It is between them and it will be necessary to lay thermal insulation material. Therefore, the main requirement to the latter is dense with clear forms. So, for the insulation of an attic roof of a private house will need to choose slab material. Such insulation includes mineral wool in mats and polystyrene foam plates, it is also a foam of high density.

But, as mentioned above, today the market offers completely unique technologies for insulation, which do not use dense materials. One of them, which manifested itself from the most positive side, this is liquid polyurethane foam. Let's start everything in order and consider each insulation separately.

Mineral wool

The definition of mineral wool includes several varieties of this building material: glass gamble, slag, stone variety. When the conversation comes to the insulation of the attic, then we must say exactly about basalt variety, as the best today. It is its technical characteristics and we will consider.

Mostly basalt wool is divided by density. Here are four positions:

• P-75 - used for insulation of pipes and horizontal surfaces;
• P-125 - It is just the same material that is used to insulate the walls of the attic from the inside with their own hands;
• PJ-175 - for thermal insulation of metal and structures;
• PPH-200 - Very dense material used for thermal insulation of rigid supporting structures.

Polystyrene foam plates

Often, this material is called foam, which is true. Just from the variety that is used for packaging, polystyrene foam plates are distinguished by density. Therefore, the material itself is very solid and durable, well withstanding mechanical loads and humidity.

Immediately make a reservation that for insulation such material is not recommended due to its high flammability and love of rodents. But if you still intend to use it, then for the insulation of the attic roof, it is better to take plates from polystyrene foam density at least 25 kg / m³.

Polyurethan (PPU)

This is a two-component thermal insulation material consisting of polyol and polyisocyanate. The two components are supplied separately in different tanks, but in the process of applying is mixed in one reservoir and under pressure are fed to the insulation sections through the hose and sprayer. In fact, polyurethane foam is a liquid substance that is quickly frozen in air, turning into a solid and sufficiently strong coating.

The basis of the quality of insulation takes the characteristics of thermal conductivity. Comparing three types, it can be noted that the weakest among them is mineral wool, the most ideal - polyurethane foam.

But this does not mean that everyone must use PPU. This material is not the cheapest, and for its application will require special equipment. True, it should be noted that the manufacturers of equipment today offer a mini station, the weight of which is only 30 kg. There are two containers with components, hoses and nozzles. The compressor will need to be purchased separately, but it is better to take it from friends or for rent.

And a few more varieties of thermal insulation materials, which in the insulation of the roof from the inside are used with their own hands.

How to insulate the attic for winter accommodation - video and nuances of the process

So, with thermal insulation materials were determined. Now consider how to warm the roof to the roof correctly.

Attention! With the insulation of the attic, two main nuances must be adhere to: the thickness of the layer must be equal to the width stropile legs, The width of the insulation must be equal to a little more distance between the rafters.

The insulation of the mansard of the Minvata from the inside with their own hands: video and photoinality

Photo	Description of work
	Minvata declines on the floor of the attic. The required width is measured, which corresponds to the distance between the rafters, plus 2-3 cm. This is done so that the insulation is consistent between the elements of the soling system, without leaving.
	Now clipped under the required dimensions, a piece of insulation should be laid between the rapid legs. If the slope of the roof slide is quite gently, the thermal insulation material under its weight can fall out of the cell.
	Therefore, along the rains from the inside, transverse rails are stuffed, which are attached temporarily to the rafter feet.
	Instead of the rail, it is possible to use a solid thread, which is stretched by carnations, driven into a checker order along the inner planes of the rafter feet.
	A laying of the insulation under the stuffed rails is made.
	It remains only to close the heat-insulating pie with a waterproofing film. Its purpose is to keep wet air pairs from penetration into the thermal insulation layer. Because mineral wool is a hygroscopic material, and under the influence of humidity, he begins to lose its properties.
	The waterproofing membrane is nailed with cloves or metal brackets to the rafter feet. Laying is carried out with lanes, starting upwards.

Attention! If one layer of minvati for the insulation of the roof of the attic is not enough from the inside with their own hands to close the width of the rafter legs, then produce two-layer installation. At the same time, the plates of the material must be laid with the displacement relative to each other. It is impossible to allow the joints between the plates in one layer coincided with the joints in the second layer.

Hansard insulation foamflast

As mentioned above, it is not recommended to use polystyrene foam plates for the insulation of the attic. One of their main advantages is low, almost zero, water absorption. Therefore, it is not necessary to arrange protective layers for this insulation. That is, if in the process of roofing the roof under roofing material, a hydro or vapor barrier membrane was not used, then the PP plates are the cheapest version of thermal insulation.

Photo	Description of work
	As in the case of mineral wool, the plates of polystyrene foam are cut under the size of the distance between the rapid legs.
	Cropped under the size of the plates are fitted into the rafter system. It is necessary to designate that there should be a space between the insulation and roofing material, which will be used in the future, as, outlining not only wet air pairs, but also some harmful components of the heat insulating material itself. Without the formation of this gap, it is impossible to store.
	From above, already on the rafters is stacked by another layer. Its main task is to close the entire surface and do not give the cold air to go between the first layer and rafters, because it is very difficult to put the PP plates tightly to the construction of the construction. The fastening of the second layer is made to the rafters with self-drawers with a wide metal washer.

It is very important to properly mix the components of the insulation, their ratio should be 1: 1.

Warming roofs of different geometry

The above methods of thermal insulation of the pitched roof were described, in which the skate is one plane. But attic attitudes and under the broken roofs, so the question, insulation loan roof From the inside, today is not less relevant. In principle, there are no serious differences in the technology itself, it applies to the use of polyurethane foam. It simply spans in one layer, without junctions.

The broken roof has a connection of two types of rafters, which form the hall. It is this plot that is the most dangerous in terms of penetration of cold air from the outside. Therefore, on the section of the connection of two systems, it is necessary to carry out without butt stacking insulation. It is best that it turns out if mineral wool is used. She is flexible, so she can give the form of bend, that is, the transition from one slope to another.

With a broken roof, the attic room is left without a ceiling. It is constructed at the level of transition. Therefore, the insulation of two slopes located in one turning plane is insulated, then the ceiling itself is also necessarily insulated. In some cases, if there is a difficulty in carrying out the thermal insulation of the upper skate or there is a task to save, the thermal insulation of the upper slope is not carried out, limited to the ceiling insulation.

What errors may occur when mansard insulation inside

Answering the question of how to properly insulate the roof of the house from the inside of the attic room with their own hands, it is necessary to understand that in itself this process is simple (not counting the use of polyurethane foam). But that the final result matches the high degree of quality, it is necessary to take into account all the nuances of the technology and accurately comply with the recommendations of specialists and manufacturers of thermal insulation materials. So, what to pay attention to:

1. Mineral Wat must be laid only if steam barlasting protection is under roofing material. Its main purpose is to remove air pairs that are located in the insulation itself.
2. Between heat insulating pie And the roofing coating should be a gap, which is used for roof ventilation. Therefore, the roofing material is placed on the crate, which is mounted on a counterclaim.
3. If the angle of slope is less than 13 °, then under such a roof it is better not to organize attic. Under such an angle, weakly comes out, so the likelihood of leakage appearance is great.
4. If attic windows are installed on the roofs of the roof, then you need to take care of their sealed installation. It is better not to do it with your own hands, call specialists.
5. If the thickness of the insulation of the insulation is greater than the width of the rafting legs, then the latter can be rake at the bottom edges of the latter.

So, we looked at how to warm the roof of a private house on the sides of the attic room. If you have any questions, you can leave them in the comments. The editors of our site will answer them.
