Technology of insulation of the attic overlap. Ceiling insulation in a cold roof house - choose one of the ways. Heat insulation of the bottom of the attic with an extended clay

Attic premises in a private house require insulation if the owners do not want to throw money into the wind, heating the surrounding space.Insulation of the inter-storey overlap on wooden beams Performs a double task: prevents the penetration of cold air in the winter and protects against the heat in the summer. At the same time, the insulation of the layer should pass a pair so that the condensate in the attic premises is not formed. To achieve the fulfillment of these conditions, work is required for the quality warming of the roof.

Since the attic space is not quite a standard room, then its thermal insulation is not a simple task. The complexity is that the roof is in close proximity to the street, and, as a rule, inclined design. Make an atmosphere in a private house comfortable for accommodation at any time of the year - with a proper insulation of the attic, for example, an eco-way. Unlike the rest of the premises of the house, the attic space is most of all to the weight loss due to direct contact with the environment.

Getting Started by the insulation of the attic, you should know what building rates and rules exist for attic overlaps. In order not to break the main parameters to which the attic design must meetcold attic ceiling insulation It should be carried out with the main requirements. For attic floors, it is strength and compliance with fire standards.

The strength of the church of the attic must correspond to the appointment of the underpowering space. If the attic arranged on the attic, then the overlaps must withstand the weight of floors, furniture and people in it. The beams of overlaps should not be fed, and the permissible load should not exceed 100 kg per square meter.

The second basic requirement is fireproof, which is especially important for houses with a wooden structure.

Important!
All structural wooden elements must be processed by special flame retardant compositions.

Fire resistance, i.e. The ability of the material and blocking slabs does not ignore, measured in hours, is regulated by the following standards:

reinforced concrete floors - 1 hour;
wooden overlaps from beams with refractory backfill - 45 min.;
wooden overlaps from beams without fridge - 15 min;
not protected wooden structures - 5 min.

Before proceeding directly to laying heat-insulating materials, it is necessary to determine the type of overlap in the attic. The most common two types of overlappings, regardless of the design of the house (brick, wooden or block). For each view of the overlap, there are their rules that will be discussed slightly below, and before this we will give the attic spaces used in the ceilingosolation basement).

Types of insulation material for overlap

Warming attic sawdusts Departed to the past, currently thermal insulation of the attic ceiling is carried out by modern materials (for example, eco-art), which meet building standards and the requirements above. Main types:

1. Mineral (basalt wool). This insulation is produced by many manufacturers and is currently very common. It is very environmentally friendly because it is basalt fibers in a stone crumb. It is high-quality protection against rodents, the material has durability, resistance to moisture, after wetting does not lose its properties and forms. Minvata can be in the shortest possible time and without much effort to insulate the attic, rolling and putting a roll, while there are no cracks and gaps, which is difficult to achieve when laying insulating plates. Insulation from the inside of the attic room of Minvata is optimal by simplicity and economy option. But the use should be approached individually and carefully, since basalt fiber sometimes causes allergies.

Tip!
For Russian climatic conditions, it is enough to use Minvatu thick 20 cm. Do not forget to use protective glasses when working with minvatu. Thermal insulation requires the laying of the vaporizolation layer.

2. Equata. Isolation of the attic is more preferable than minvata, since this material does not cause allergies. Made from cellulose fibers, eco-friendly sold in bags and stacked between beams. This insulation does not burn, since it is impregnated with special refractory compositions. Also, when insulated with eco-paper, a vapor barrier device is required. Of the minuses, you can note the high cost of eco-insulation.

3. Glasswater. The type of mineral wool, but with certain features associated with the raw materials from which it is produced. Since the production of glass gambles go waste of glass products, during its use, dust is formed harmful to the human body. Working on laying should be carried out in special clothing, using glasses and respirator. Refers to the budget variant of insulation. The advantages include high thermal insulation, low cost, lack of toxicity, not flammable. Variazolation is needed.

4. Styrofoam. Insulation of the attic foam is the most economical way. This material has a low density and is well cut with a knife. Laying foam plates should be carried out very tight, and large gaps are closed with construction foam. Isolation of refractory foam, at high temperatures melts with the release of poisonous gases.

5. Foamed polyurethane (penoplelex). Refers to modern technological materials.Insulation attic polyurethane foam It is performed by applying it by spraying devices. The price of polyurethane is quite high and the technology of laying it is not the simplest. The advantages include high speed of polyurethane on the walls and ceilings from the inside of the attic. The whole floor can be covered with a penplex in a few hours, while achieving the complete absence of gaps, in contrast to thermal insulation plates.This option is comparable to an eco-water insulation. Laying is recommendedparosolation and inside.

6. Bulk materials. In the old house structures, a mixture of sawdust and dry leaves were used.Warming wooden overlap Keep warm in a private house, but had a high fire hazard. Currently, the device of bulk insulation uses perlit, slag or clay. Such thermal insulation is somewhat heavier than the first four types, so you should carefully calculate the strength of the design of overlaps and the ceiling binder. It is more often used during overlaps made from plates. Clamzite is also not badosolation basement.

The correct method of insulating the rolled material and insulation in the form of plates, consists in laying it on the beam in several layers in a checker order. This method of using heat insulators will avoid the formation of cracks.

Proper and ceiling attic

Warming of slab overlap

As mentioned above, the overlaps exist two types. The overlapping of the attic floor with reinforced concrete slabs is found in large houses with several floors. Design from plates that can be hollow or solid, also requires insulation. Here, the process of thermal insulation device is somewhat simpler, since there is a flat plane on which any insulation can be laid.

The slab floors most often fall asleep with slag or clay, since the stove strength is high enough. The thickness of the insulation layer varies from 25 to 35 cm, the vaporizolation is pre-stacked.Warm attic With an attic requires a cement screed device.Warming of beam overlap

The beam overlap is more common in the designs of private houses. Insuction in this case is carried out by laying heat insulators between beams. Before that, vaporizolation must be made to remove moisture from the premises of the house. Specialized vapor insulators work as a valve, having the ability to skip air from the inside and do not pass the cold masses inside.

The ideal option, if you manage to arrange a solid vapor insulation layer. But when the design features of the attic overlap prevent this, then the film should be laid between the beams of the mustache and attach a construction tape for tightness.

With an insufficient height of the beams, so that the insulation can be laid in the evening, the additional rails should be touched. For high-quality insulation from the inside of the beam attic overlap, and also to getwarm attic in the house, you can lay a few species of various heat insulator.Healing floor attic will give an additional effect.

Warming overlap over wooden beams

To deal with what is necessary for the insulation of the overlapping of a cold attic, let's clarify, why do you need an attic in a private house and what kind of purpose is it. Our ancestors were erected at home, which could have to breathe over 100 years, while inside it was warm, and the wooden roof design remained dry.

Previously, basically built two-tie roofs with a small slope slope. It was done so that winter snow could stay on the roof. Thus, the snow was used as a natural insulation. In the attic, one or two windows were made and kept them in winter closed, so that the air served the thermal insulator. In the summer, there was a somewhat different situation. The attic windows opened overnight so that the air be cooled, and in the afternoon, they were closed in hot weather so that the air is not heated strongly, adjusting, in such a way, its temperature.

When the snow fell out in the winter, he went to bed with a solid cover to the roof, becoming at the same time natural insulation. Even with large frosts, the temperature in the attic did not fall below zero. Thus, the air in the attic room and the insulation of the overlap allowed the temperature in the house at + 20-25 ° C. The rods of the roof were not insulated, so that the snow, lying on the roof, was not pushed. The rafter system remained open, giving an opportunity for its inspection and repair if necessary. Therefore, in a cold attic, only overlapping is insulated.

If the roofs are insulated, the attic becomes heated by the room, i.e. An attic, which has a completely different functional destination.

Now it remains to find out how to insulate the church of the attic in a private house, and what materials are used for thermal insulation.

Materials for insulation overlapping attic

There is a wide range of materials for insulation. To determine the choice, it is necessary to take into account the conditions in which the thermal insulation material will be used:

The material must maintain its properties at temperature modes from -30 to +30 ° C. It should not be wrapped with strong frosts and should not be distinguished by harmful substances with hot weather.
It is necessary to choose a fire-resistant insulation in the case of electrical wiring in the attic room.
The material is better to choose moisture-resistant so that during wetting it does not lose thermal insulation properties.
The insulation should not quickly lay out to fulfill its destination as long as possible.

Before deciding on the type of material for insulation of the floor of a cold attic in a private house, it is necessary to take into account, from which material is done overlap. If the sex is made of wooden beams, you can use slab, rolled and bulk insulation. In the case when the attic is made of concrete slabs, then resort to the use of heavy bulk or dense slab thermal insulators. Their use makes it possible to make a cement screed on the floor.

Materials manufactured in plate and mats format:

mineral Wat (Minvata) in mats;
styrofoam;
extruded polystyrene foam;
seaweed;
straw.

minvata;
glass gaming;
stone wool;
algae ladders;

Bulk materials for insulation floor attic:

ceramzit;
equata;
reed;
sawdust;
straw;
slag;
buckwheat tyrsa;
peluons of foam.

Insulation overlap the attic in a wooden house must be performed by environmental, natural and breathable material.

How to insulate the sex of the attic mineral wool

Mineral wool - common and modern heat insulator. Released in rolls or plates (mats). It does not rot and not burn, rodents and various kinds of microorganisms are also not terrible.

The insulation of the overlapping of a cold attic mineral wool begins with laying a lining material on the floor. For a budget version, pergamine, but more expensive and high-quality option - flooring from a vapor barrier film are laid out. The film is laid with the allen, and the jokes are sickling with scotch or fasten with wooden slats, which are fixed by the construction stapler.

The width of the insulation is selected based on the requirements of heat engineering norms for each region. Mineral wool laid between the lags tightly and without cracks. The locations of the joints are sickling with scotch. After the insulation is laid, there are simply boards on the lags, thus forming the floor in the attic. Such a simple solution for creating a floor allows the Minute to "breathe" and normally ventilated in the event of moisture on it. In order to warn moisture in the minorvatu under the roof laying the waterproofing material.

Mineral wool laying are produced in personal protective equipment: dense clothing, glasses, gloves, respirator.

Insulation slabs overlap the attic extruded polystyrene foam

The polystyrene foam or foam is not very dense materials, so they are used when the sex of the attic represents the structure of the lag and beams. In case of the need for thermal insulation, plates use insulation overlapping a cold attic extrusion expanded polystyrene. This material is stronger and respectively denser than the usual foam. Before placing the slab surface should be aligned. From the warm side of the floor, vaporizolation will not be required, since concrete slabs vapor permeability is almost absent.

On the aligned concrete slabs are laid by a vapor barrier film. Next lace out the plates of extrusion polystyrene foam in a checker order. The joints are blending by mounting foam. After the foam dry and hardens, the heat-insulating plates are poured with a concrete solution with a thickness of 4-6 cm. When the screed dry, it is already suitable for use as a floor. Although you can go further and put on the screed any flooring.

Thermal insulation of a cold attic eco-art

Eco-cellulose, lightweight and loose insulation, consisting mainly of waste paper and newspapers. Other components - a bora and boric acid are used as flamesmaking substances.

Before insulation, it is necessary to put the film on the floor. Eco-plating procedure is made using a special reveal installation. The insulation layer is applied with a solid cover without creating slots. Since the eclaw contains a large amount of air, it is usually enough layer in 250-300 mm.

Do not forget that over time, a shrinkage of material will occur. Therefore, apply an emota layer for 40-50 mm.

After the insulation of the overlapping of a cold attic is an eco-art, it must be moistened. Make it can be ordinary water or prepare a solution of 200 gr. PVA glue on a bucket of water. Moisten the usual broom in this solution and wet your wool well. After drying, there is a crust - lingin on the surface of the wool, which will not allow you to move wat.

As you can see, the methods of insulation of sex in the attic abound. Which one to apply depends on each specific situation. The main thing, observe the correct laying technology of heat insulation! Then it will always be warm in your home, and the materials used will serve for many years.

How to properly insulate the overlaps of a cold attic of Minvata?

By ensuring the insulation of the private house and insulation of the roof in terms of rafters, do not forget that special attention should be paid to such a place as a attic.

Development of insulation of the attic overlap of Minvata

Warm air tends to rise to the top, and therefore, in the temporarily unheated room, heat can go through the cold attic space. Therefore, the insulation of the attic need to be solved without postponing.

1 Why do you need the insulation of the floor of the attic?

The insulation of the cold floor is the attic stone or mineral wool, by and large, you need to do smallly operated rooms that are properly equipped with special roofing ventilation.

An attic, or rather its overlap performs the function of a peculiar border of heat and cold. In such places, the shutters are subjected to intensive exposure to moisture due to condensate formation.

However, it is possible to warm the overlaps in the attic of the house with your own hands. The process of warming insulation in the attic of the Minvata is to create a solid thermal insulation coating, which will differ in a low degree of thermal conductivity.

The technology of insulation of the Minvata overlap in the attic as the thermal insulation of the power flow for pipes implies a strict adherence to its stages and requirements.

By itself, this technology is quite simple and understandable. Good insulation of the floor of the attic with the help of mineral wool helps to close unwanted slits.

For this, the insulation must be laid tight. In most cases, minvat is used for insulation of the attic of the house.

The insulation presented is the most suitable for the work of this type, they can also be insulated the floor surface in the residential premises of the house.

Sketchy insulation of the attic overlap of Minvata

When organizing good insulation of mineral wool, the most optimal temperature will be maintained in the residential premises.

If the procedure is incorrect, then the moisture rising from the floor of the house will lead to condensate formation.

It will accumulate on the ceiling, and then leak through the floors. The resulting temperature difference in those areas where attic floors are adjacent to the walls of the house, initiates the formation of mold and microscopic fungi, which can be causative agents of allergic diseases.

1.1 Insulation Requirements Attic

The process of insulation of the floor of the attic and insulation of the roof of the house with their own hands, and more precisely the level of its quality has a direct effect not only on the dimensions of the heat loss, but also for the duration of the operational period of the entire rafter design and roofing.

The fact is that water couples inside the heated premises diffuse to the attic of the house. In order for the insulation used to ensure the high degree of calculated thermal insulation layer, it should always be dry.

Based on this, the insulation must be protected from excessive moisture by pairs of ascending heated air using a special playproof material.

If the attic room is well insulated, it will ensure not only high-quality thermal insulation, but also contributes to an increase in the operational period of the entire roofing design.

Warming overlapping of a cold attic Minvata

If vaporizolation is absent, then the pair will penetrate the unprotected overlap of the attic room and condensed on the surfaces of the overlap.

This will lead to the fact that the moisture will be drained on rafters, which under its impact will begin to rot from the inside.

As a result, the likelihood of destruction of the entire roofing cake increases. Thermal insulation indicators of the design are also reduced due to the fact that the tightness of the vaporizolation layer was broken.

Before you insulate the attic, you need to drain the layer and remove moisture from the entire attic space. To do this, perform ventilation through windows. They can be:

In order to ensure the maximum ventilation intensity, the indicator of the total area of \u200b\u200ball the ventilation holes should be 0.2-0.5% of the attic floors.

If all work is carried out competently, then in the winter, the roof will not form icicles. The process of insulation of the attic space is made not from the side of the residential premises, but from the floor of the attic.

So the most convenient to lay the insulation, the choice of which depends on the technology used and the structural features of the structure.

1.2 Features of the insulation of beam overlaps

When implementing such a scheme of insulation using minvats, heat is stored in space between beams. There are almost always enough of their height for this, but if necessary, several bars are stuffed from above.

Ceiling insulation of the Ceiling by the attic

The lower part of the overlap is sewn with the help of a handy material as when the attic of a private house is insulation. To do this, the lining or plasterboard sheets can be used.

Top of the beams produced a bed flooring flooring. It can be a tipped board, a plywood sheet or OSB stove. Mineral wool is settled on a pre-prepared special vapor insulation layer.

An alternative to him can serve as an ordinary film made with polyethylene. If the steam insulating material is fooled, then it is placed in a shiny surface down.

The intermediate distance between the beams is filled with minvata with the desired thickness parameters. The surface of the beams should be equipped with an additional insulation layer.

This will lead to the blocking of the so-called cold bridges and significantly reduce the overall level of heat loss. If the high quality bar was applied to create beams, then the finishing material should be shame right on their surface.

Minvat is located between them as when the roof is insulated with the PPU, and the attic floor is made from above. The use of such technology is especially relevant in homes that are made of logs or bars.

It is important with a high degree of reliability to protect Minvatu from entering the smallest drops of moisture, especially this is true if the roof has minor coating defects, due to which leaks occur.

The layer of mineral wool must be reliably protected from wind exposure from the cornice. For this, plates from minvati have a high density density.

2 Why is the insulation of the attic use Minvatu?

In most cases, when insulating the attic floors, the consumer selection falls on mineral wool. Its advantage is that there are no special skills for its laying.

Mineral wool is distinguished by excellent heat insulating qualities. Its structure consists of thin vitreous fibers, the length of which ranges from 2 to 60 millimeters.

Warming attic Minvata

High sound insulation features are provided due to the presence of a large number of air pores.

These pores are located in space between the fibers and can occupy 95% of the total volume of the insulation. Minvat is represented in three varieties, it can be basalt glass and stone.

Basalt wool is manufactured using molten basalt breeds in which the binding elements are added.

This may be a carbonade type breed that regulates the level of acidity of the substance, which entails increasing the operational term of the insulation. Glasswater exhibits high heat-resistant properties and is able to withstand temperatures up to +450 degrees Celsius.

2.1 Technology of insulation of the attic overlap of Minvata

During the work of mineral wool, it is important to comply with all safety requirements and regulations.

This is due to the fact that in the process of cutting and laying such a material, the air is filled with the smallest particles, which can enter the breathing organs and cause harm to human health.

When making installation, it is necessary to take care of the availability of personal protective equipment. In stock There should be glasses, a respirator and gloves from dense rubber.

The process of insulation of attic ceiling begins with the selection of the necessary tools and additional materials. Do not do here without:

The essence of insulation technology is that the insulation must be neatly laid into the space between the attic overlaps or beams.

To enhance thermal insulation qualities, reliable vapor insulation protection should be applied. Warm and rich in moisture air will continuously rise from the residential rooms and hit the top through the overlap.

There, in the underpants space, it will face a layer of insulation. Due to the fact that mineral wool is generally recognized considered to be a steamproof material, it will take all the moisture outgoing moisture inside.

If it remains without the right access of air and sunlight, it will gradually be picked up and, in the end, will lose all its heat-insulating qualities.

Cold Cold Inter-storey overlap 20 cm min watts

In order to avoid such destructive consequences, it is necessary under the layer of mineral wool to lay a vapor insulation material.

Before starting the main work, it will be necessary to carefully make the calculation of the desired number of insulation.

The amount of wool purchased depends on how many layers are planned to be used when coating an attic room. In addition, the thermal insulation thickness parameter directly depends on the characteristics of climatic conditions in the region.

Warming overlapping of a cold attic Minvata

The insulation of the overlapping of a cold attic of Minvata is the advantages. Features of insulation overlap of cold attic Minvata.

Rules of insulation overlapping mineral wool: 1st floor and attic

When building a private house, special attention should be paid to the insulation of structures. Important elements that are subjected to direct exposure to cold air are overlaps of the first floor with a cold basement, outdoor walls, attic floors, an attic roof. Mineral wool can be used as a universal type of insulation.

The insulation of the overlapping of the Minvata allows you to provide a comfortable floor temperature and maintaining heat in the room. Thanks to its non-hatching, the material can be used both in wooden and stone construction without any concerns.

What is Minvata.

This insulation is the material of the fibrous structure. Fibers are located in chaotic order. Each manufacturer has its own preparation recipe. All components are melted at very high temperatures, and then burst into thin fibers in the centrifuge. Next, using heat treatment make mineral wool.

Types of mineral wool

For the construction of the Minvat's house produced three species.

Glass. The material is made of broken glass.
Stone. This species can be called the most common. Most often you can meet material from basalt fiber, but it is made from other minerals. It is easier to produce warming a stone wool compared to two others.
Slag. It has the lowest thermal insulation characteristics and increased fragility. Not suitable for facade works and pipelines.

In addition to this classification, there is a division in the form in which mineral wool is produced.

Rolled material - has low rigidity, therefore, it is more used to insulate the walls of the house or sex by lags.
Rigid mineral plates or mats are excellent for use in the insulation of overlaps and the attic roof.

For the insulation of the floor covering, it is preferable to use the second option, since the rigid mineral wool will provide a reliable operation of the floor under load.

Dignity and disadvantages of material

The positive qualities of mineral wool can be attributed:

good thermal insulation;
simple laying technology, in the construction of the floor of Minvat does not require special consolidation;
low degree of absorption of moisture from the environment;
democratic price;
resistance to high temperatures and open fire;
safety for a person under technology compliance;
resistance to the effects of bacteria, mold and fungus.

Thanks to these qualities, mineral wool received a mass distribution, both in wooden and stone construction.

But it is impossible not to say about its peculiarities and disadvantages, which include:

the need for additional protection for workers: overalls, gloves, mask;
it is necessary to ensure protection of insulation from moisture, the technology includes vaporizolation and waterproofing;
the ability to absorb water, the impossibility of use for wet premises;
high degree of shrinkage in violation of installation and operation conditions;
when laying in a wooden building between the lag, it is necessary to provide a gap between the insulation and the outdoor coating structure of 3-5 cm.

If not to take into account these features, insulation will become dangerous for a person, for example, the lack of workwear in the workers will result in fraction of the material of the material on the skin and into the lungs. This will cause irritation, itching, allergic reactions.

Application when insulating floors

As the warming of overlapping in the house, mineral wool plates are used in the following cases:

in the design of the floor of the first floor in the presence of a cold basement or underground;
in the design of the interhent overlap to enhance sound insulation;
in the design of the attic ceiling in the presence of a cold attic.

For an individual house when laying in all cases it is necessary that the technology is strictly observed, otherwise the insulation will not perform its function.

Warming technology

When laying the insulation, technology must strictly follow. "Cake" insulation depends on the type of overlap, so let's consider the instructions below.

Overlap of the first floor

In the presence of a cold basement or underground requires insulation of the floor design. Regardless of which building works, wooden or stone, layers are laid in the following order when mounting mineral wool from above:

In a wooden house-building, a slab or rolled material is stacked between lags in compliance with the order of the layers. It is possible to fasten the material from below, it is more competent from the point of view of heat engineering, but very laborious.

Warming by minvata from below

Noise isolation of intergenerational overlaps

As protection against the propagation of sound, mineral wool is placed in the cake of the floor in compliance with the following order:

The event is particularly effective when erecting a brick or concrete house, but in a wooden will not be superfluous.

Note that in the w / w overlapping overlap for damping and air noise is enough 3-5 cm Minvata under the tie. And in the wooden floors, the material layer should be at least 5-10 cm.

Insulation of the attic overlap

If the building provides a cold attic device, it is necessary to protect the overlap of the upper floor. In a wooden building, the mineral wool is stacked between the lags, in the stone - both between the lags and under the cement screed.

The order of laying is the same as in the previous case. The difference lies in the material of the floor covering the attic and the thickness of the insulation layer.

The protection of the design in this case is carried out to prevent unnecessary thermal losses from the room to the room of a cold attic. The heated air accumulates precisely under the ceiling and in the absence of the necessary activities, the attic falls in the uniform, creating large heat loss for the house.

Calculation of thickness

In an individual house there are no requirements for the heat-stash structures, therefore the insulation thickness can be selected approximately. It depends on the territory climate, for most cases, it is enough to protect the mineral wool thickness of 100-150 mm.

To calculate a more accurate value, you can use the help of a specialist or a simple "Teremok" program. It can be found on the network in free access.

Mineral wool is a modern thermal insulation material, which, with proper use, will last long and reliably protect the elements of the building. The material is suitable for work with all types of floors from the basement to the attic.

Hearth overlapping Minvata: attic, floor 1 floor

Thanks to its non-combustible, the material can be used both in wooden and stone construction without any concerns.

Insulation attic and attic overlap

For a comfortable operation of the building, it is necessary that the attic of the attic is well thermally insulated to eliminate the temperature of the ceiling surface below the dew point. Otherwise, the stains of moisture will be sure to appear on the ceiling and walls, which will only worsen the appearance of the room, but will cause the rise of mold and the development of fungi, from which to get rid of problematic. Therefore, increased requirements are presented to the thermal protection of the attic ceiling.

Cold attic ceiling insulation

In accordance with the standards, the heat transfer resistance for the attic overlap should be at least the following value: RO \u003d 4.15 m 2 · ° C / W. The attic overlap of the country house is insulated with mineral plates (basalt) or glass wool. The insulation plates need to be laid between ceiling beams or overlap plates. Mineral wool is placed on a layer of vapor barrier or plastic film.

Fungalized thermal insulation material is placed in a shiny side down. The space between the beams is filled with a layer of thermal insulation material. To reduce heat losses through cold bridges, another layer of thermal insulation is stacked on top of the beams.

To reduce heat loss from light fibrous insulation under the influence of drafts, it is protected by vapor-permeable windproof material. The use of such a material makes it possible to increase the heat protection of the church of the attic and protect the insulation from wetting if there will be drops of moisture (with damage to the roof or leakage).

From the cornice layer of the insulation, it should also be protected from wind plates of mineral wool of high density or boards, which are installed on the edge.

Warming attic roof

An attic or attic rooms separated by partitions on the compartments can be insulated in different ways.

The first way: if the attic is non-residential, then only the floors should be insulated - the ceiling flooding of the building.
The second way: if the attic has an attic, then it is necessary to warm up, except for floors and roof.

For insulation roofing, the attic and premises are commonly used:

Building felt.
Mineral wool in various design.
Styrofoam.
Polyurethan.
Basalt, glass wool, eco-tree.

Floors in the attic can be insulated with the following materials:

Building felt, mineral wool, glass gamble.
Penosilicate plates.
Ceramzit, slag, ash, sawdust, straw, reed.

Behind the insulation of the attic checks of the overlapping and roofs are checked, the gaps are close to packles, wetting in a lime solution. You can also use the mounting foam, silicone adhesives and sealants.

Before performing work, all structures made of wood are coated with antiseptic and flame retardant compositions.

When the roof is insulated from asbetic sheets, special attention should be paid to the processes that are formed by the waves of asbotic sheets. If there are cracks, they are filled with packs in a lime solution.

The presence of protective covers, collars and aprons are checked in places of adjuncing asbocate sheets to parapets, pipes and walls. Inappropriate the elements of the coating on protective overlaps follows at least 15 cm.

Alternative to the insulation of the attic - it is warming up the ceiling in a private house. The effect of work will be approximately the same.

But here the mansard ceiling insulation instructions. Step bypass tell how to spend work from beginning to end

Insulation attic various materials

For insulation of attic rooms and attic in a private house, different insulation are used:

The process of insulation is the same for all materials, so we consider insulation the attic on the example of Minvati.

Before starting insulation, the attic must be waterproofing the roof. Mineral wool is universal and convenient to work, has a low thermal conductivity and density, well withstands high temperature and insensitive to an aggressive environment. Also mineral wool is an excellent soundproofer.

The attic slopes can be insulated with plates and mineral wool mats. The plates are tougher, and the mats are elastic, this property helps better and more tightly. Also used mineral wool mats with a foil coating for vapor barrier.

Since usually the thickness of mineral wool is more than the thickness of the rafter, there are lining on them to increase the thickness. Also, the pre-rafter system is impregnated with antiseptic solution.

The mineral wool is placed in the intervals between the rafters on the crate and closes with a wrap for vapor barrier. The vapor barrier film is stacked by the bracket on the rafter system. The width of the floor overlap is visible on the film - the line is stuck along the edge of the canvas. Film joints are isolated by special glue and adhesive ribbon.

Floor insulation ceramzit

Stop the clamzite on the floor of the attic should be on the runneroid. The thickness of the ceramisite layer is determined by the thermal conductivity of the floor, but in any case the thickness of the clause must be at least 15 cm, and better - 20-25 cm.

It is known that through the ceiling can leave up to 15% of heat from the house. Therefore, to reduce thermal losses, the ceiling is insulated by clay and other materials. Ceramzit not only keeps heat, but also increases sound insulation.

Ceramzite is usually used to insulate concrete overlap. To do this, it is covered with a layer of 200-250 mm, on top poured with cement tie up to 50 mm thick. The screed will serve as a floor.

The cement-sandy solution for a screed must be a dense consistency so that it does not flip into a filling from the clay.

Mineral wool insulation

Stop mineral wool follows from the long point of the attic room.
Crop the insulation is needed on a solid surface.
Beams, pipes, ventilation wells, etc. It should be closed with insulation.
Mineral wool should be laid in a layer at least 25 cm.

When working with mineral wool, individual protection means are necessary. These are protective glasses, rubber gloves, respirator and long sleeve clothing. It is impossible to work next to the open food and drinking water. Mineral wool hit on the skin causes irritation and itching.

In fact, Minvata is widely used in construction, for example, when the facade of mineral wool is insulation.

Insulation polyurethane foam

Insulation the attic of the polyureture is made by spraying on partitions, roof, frontones and attic floors, so the thermal insulation layer is obtained without seams and joints, that is, a monolithic steamproof layer is obtained.

Polyurethane foam has a low thermal conductivity coefficient, therefore the thickness of the polyurethedane layer is several times less than a layer of minvati or foam.

The use of polyurethane foam increases the useful area of \u200b\u200bthe attic room.

The attic, insulated by spraying the polyurethane foam layer, is not subject to the influence of humidity, condensate is not formed on the walls, because polyurethane foam holds warm air inside. Moisture does not pass through polyurethane foam and can not settle on a cold roof.

Warming sawdust

Floor insulation sawdust is used only on non-residential attics, since when the saws, the sawdust will gradually be compacted, which will lead to the appearance of cracks on the concrete screed. The most common solution recipe using sawdust for insulation Paul attic:

Ten buckets of small wood sawdust.
One cement bucket, a brand of at least 300.
One bucket of lime-puffs.
Ten liters of water with antiseptic. It may be boric acid, copper vigorous, household soap.

The volume of water varies depending on the humidity of the sawdust. A finished solution from sawdust is stacked with layers 20-25 cm thick and tamper. All building materials that are used in the walls of the house must be vapor permeable. That is, it is impossible to use runneroid, polyethylene, tol and other materials that do not pass moisture.

From above, the sawdust layer when insulation is closed by shields from plywood, fiberboard or boards. The thickness of the sawdust layer on the walls should be at least 15 cm, on overlappings and on the floor - at least 25 cm. When the floor insulation, a cement screed is made from a thickness of 5-10 cm.

Insulation of the attic and attic rooms with their own hands - materials and methods of insulation

Insulation The attic of a residential building is necessary to avoid heat leakage and to save energy during the heating of the building. Using various insulation

If the roofs are insulated, the attic becomes heated by the room, i.e. An attic, which has a completely different functional destination.

Now it remains to find out how to insulate the church of the attic in a private house, and what materials are used for thermal insulation.

Materials for insulation overlapping attic

There is a wide range of materials for insulation. To determine the choice, it is necessary to take into account the conditions in which the thermal insulation material will be used:

The material must maintain its properties at temperature modes from -30 to +30 ° C. It should not be wrapped with strong frosts and should not be distinguished by harmful substances with hot weather.
It is necessary to choose a fire-resistant insulation in the case of electrical wiring in the attic room.
The material is better to choose moisture-resistant so that during wetting it does not lose thermal insulation properties.
The insulation should not quickly lay out to fulfill its destination as long as possible.

Materials manufactured in plate and mats format:

mineral Wat (Minvata) in mats;
styrofoam;
extruded polystyrene foam;
seaweed;
straw.

Rolled insulation:

minvata;
glass gaming;
stone wool;
algae ladders;

Bulk materials for insulation floor attic:

ceramzit;
equata;
reed;
sawdust;
straw;
slag;
buckwheat tyrsa;
peluons of foam.

Insulation overlap the attic in a wooden house must be performed by environmental, natural and breathable material.

How to insulate the sex of the attic mineral wool

Mineral wool - common and modern heat insulator. Released in rolls or plates (mats). It does not rot and not burn, rodents and various kinds of microorganisms are also not terrible.

Mineral wool laying are produced in personal protective equipment: dense clothing, glasses, gloves, respirator.

Insulation slabs overlap the attic extruded polystyrene foam

Thermal insulation of a cold attic eco-art

Eco-cellulose, lightweight and loose insulation, consisting mainly of waste paper and newspapers. Other components - a bora and boric acid are used as flamesmaking substances.

Do not forget that over time, a shrinkage of material will occur. Therefore, apply an emota layer for 40-50 mm.

Ask any builder about the need for insulation of structures, and he will definitely tell you that it is necessary to warm up all the buildings in which it is expected to live and work to work.

Exceptions are only temporary buildings, where a person conducts little time, small architectural forms and buildings, which are placed in very warm climatic belts.

For these buildings, solid thermal insulation is not needed, as the temperature on the street is even not lowered to extreme values. Special attention should be paid to the insulation of attic floors. This process now will be discussed.

1 Features and appointment

Warming overlaps need to be given no less attention than the insulation of walls or sex. Someone may argue, they say, why concentrate not thermal insulation of overlaps, if much more important to protect from the heat loss of the wall.

Indeed, the walls are hardly the main design, which cools the house even with. This is explained by their large square, length and thickness. Wall in the winter season can be wrapped, thereby seriously lowering its temperature, which means the temperature indoors.

There is another moment that concerns the spending of resources for heating at home. Excessive heat from radiators can warm the wall completely, but almost half of the thermal energy it will give outward.

The builders have such a process on professional jargon called "to warm the street." As you understand, this is at least the unprofitable use of resources.

However, attic floors have no less priority. To understand why you need the calculation and thermal insulation device for overlappings, it is worth referring to the laws of physics.

According to these laws, warm air always strives to up, and the cold is below. If we are talking about a house or room, then here the space is closed most of time, and therefore the air has much to go. As a result, warmer air flows are mainly under the ceiling.

If you have a cold ceiling, then they are cooled, and fall below, freeing the air space with a higher temperature as. As a result, it turns out a peculiar reverse circulation, when the room temperature drops slowly, and everything is due to a laptile overlap, which has a reduced temperature.

It is especially important to insulate the attic floors. After all, the attic is, in fact, the non-exploitable room. It is rarely insulated properly, leaving in the form of a peculiar buffer space. Therefore, the temperature in it, albeit higher than outside, but still quite low.

If you have monolithic or prefabricated patterned overlaps, then you are still very lucky. Concrete, although he does not oppose the loads too well, but still is a high density material. It slowly cools and creates significant obstacles to reduced temperatures.

However, many buildings, attic floors are put on wooden beams. The device on wooden beams makes it possible to perform work with your own hands, and significantly reduce the cost of arranging overlap, but its thermal insulation properties are difficult to be called acceptable.

The simplest overlap of this type consists of beams that are styled wooden boards, and the insides are at best poured with a small screed or flowing materials.

2 Types of materials for the insulation of overlaps

Let us turn to specific insulation that most often used for the heat insulation of overlaps.

Insulation can be the most diverse, their thickness and optimal characteristics are determined after all parameters calculate.

However, the calculation is not always needed. So, if you gathered to insulate the standard attic overlap with the base of the reinforced concrete plate, then you will have 7-10 cm insulation of the Minvata or about 5 cm insulation of the penplex.

If you need to protect the overlaps on wooden beams, then the necessary thickness will be slightly larger, as wooden floors, even with filling does not give the same resistance to the loss of temperatures. Therefore, on top of the main structures on the beams will have to lay the layer of the insulation more.

2.1 Technology of insulation and its nuances

You can warm the attic overlap yourself. Especially if you need to work with wooden beams. Everything is already prepared for work here. You only need to fill the space between the beams and make it as much as possible.

Stages of work:

It almost does not matter, you use minvatu or polystyrene foam materials, in any case they are mounted by the same technology.

If necessary, they can be additionally fixed by dowels, but only if the overlap has the basis and does not consist of one only beams, which, from two sides, bent a boardwalk. Paro- and waterproofing are fixed using a conventional stapler to beam elements or crate.

2.2 Warming of overlapping with liquid polystyrene (video)

Specialization: Capital construction work (bookmark the foundation, construction of walls, roof design, etc.). Domestic construction work (laying internal communications, roughing and finishing). Hobbies: Mobile communications, high technology, computer equipment, programming.

If you in the near future are going to do it with your own hands to carry out the insulation of the inter-storey overlap on wooden beams or the thermal insulation of the attic overlap in a private house, then, undoubtedly, you will need a heater for overlapping.

It is the question of how the wood or reinforced concrete overlap between the floors, I want to talk in this material. The instruction provided will help you choose that thermal insulator, which in the best way to cope with the tasks assigned to it.

The need for insulation

For the dwelling to be comfortable and cozy, it is necessary to maintain a certain microclimate in it throughout the year. That is, in the winter to fuck, and in the summer - air-condition.

And in order for it as much money as possible, the dwelling must be built on energy-efficient technologies, insulating it with thermal insulation materials. Especially when it comes to a cold attic and the floor separating the basement from the residential floor.

There are several groups of materials for this:

fiber (mineral wool);
slab (foam and similar materials);
bulk (sawdust, ceramzit and so on).

All of them have different specifications, and the installation technology is different. Therefore, in each particular case, something specific is used. Take this and talk more.

Mineral wool

To this class of insulation materials include three types of thermal insulators:

fiberglass;
wool based on slags;
mineral wool.

According to GOST, having the number 52953-2008, these materials may have different thickness and length of the fiber, that is, as a result, different specifications: fire prevention properties, the ability to carry mechanical loads, moisture resistance, thermal conductivity, and so on.

The thermal insulation of the shots of the attic or the base can be performed by any mineralized insulation. But what exactly will it be done most effectively? I will tell about it below.

Glasswater

The material, as can be seen from the name, is made of glass fiber, the thickness of which can be in the range of 5-15 microns, and the length is 15-50 mm. The fibers are connected to each other, as a result of which the insulation becomes durable and elastic. And the presence of air inside allows it to maintain the desired temperature indoors.

Exact specific specifications are below:

the thermal conductivity coefficient is between 0.03 and 0.052 watts / (M * K);
possible heating temperature - up to 500 degrees Celsius;
wat does not lose its properties when cooling up to - 60 degrees Celsius.

However, the insulation of the attic overlap on wooden beams with the help of glass gambles, so popular in the recent past, is now practically not used, and the material itself gave way to the palm of the championship to other mineral fiber-based products.

The thing is that this kind of mineral wool has one significant disadvantage - the spread of glass dust around itself. Bringing, the threads of the insulation can cause irritation of the skin, respiratory tract and mucous membranes. When working with glass, it is necessary to use the means of protection, and to mount it so that the glass dust does not fall into residential premises.

Shagkovat

The raw material for the production of this type of insulation is the waste of domain production - slags, of which fibers in 4-12 microns thick and 16 microns are formed.

Characteristics slag are as follows:

thermal conductivity coefficient - 0.46-0.48 watt / (m * k);
permissible heating temperature - 300 degrees Celsius. If you allow the heating of the insulation above this mark, the fibers are melted with each other and the heat grinding properties of the wool fall sharply (I would say, disappear completely).

I practically did not meet cases when this material was used for the warming of overlaps. And all because it has a large number of minuses:

Fragility. With careless circulation, the fibers made from slags are cleaned, forming small dust that can harm human health.
Gigroscopic. The material absorbs moisture well, so it can not be used to insulate the surfaces in those places where there is a danger of its wet.
Residual acidity. The insulation in wet air can aggressively affect the corrosion of the surface. Therefore, if you warm the sex of the attic, then not a water supply.

Stone Vata.

If you really choose than insulate the attic room (from the category of materials under consideration), then I would prefer the stone cotton. Her fibers are the same in size as Slagova, but they are not fragile and not dust.

As for the coefficient of thermal conductivity, it ranges from 0.077 to 0.12 watts / (M * K), and the material itself can be heated up to + 600 degrees Celsius. Stone wool is also hygroscopic, but after evaporation of the accumulated moisture restores its heat insulating properties.

In addition, there are materials that are impregnated with special hydrophobic substances. That is, the drops of moisture, penetrating the insulation layer, almost do not delay there, evaporating through the ventilation gaps.

Of all the mineral wool presented in the species market, I most like basalt. Unlike the classic insulation, in which there are present in some amounts of slag, charge, clay, limestone and others, this one is made from the mineral of volcanic origin. And this gives it improved technical characteristics.

Thus, in the manufacture of stone wool, formaldehyde resins are used, which bind fibers with each other. That is, there is a emission of chemical compounds harmful to humans. Although it is minimal, the danger of harm to health is saved.

The insulation of the overlapping of a cold attic Minvata based on basalt is carried out as simple as possible, since the heat insulator is supplied in rolls, and in mats strictly fixed size, which are easily placed between lags.

Basalt wool is a fireproof material that does not burn, does not contribute to the spread of the flame and does not highlight dangerous combustion products. Therefore, it is ideal for insulation of cerpent rooms, and especially exploited.

The only minus of this type of insulation is a rather high price, which, however, is fully justified with high technical characteristics.

Mineral wool brands

If you have decided to perform the warming of overlapping - the base or attic - Minvata, I will help you understand the variety of fiber insulation. That is, we list the main brands of mineral wool and the sphere of their use:

P75. This means that the density of the insulation is 75 kilograms per cubic meter. It is used to insulate overlaps, which are not permanent load (for example, on a non-exploit attack). Also such cotton can be insulated with engineering communications.
P125. Suitable for insulation overlap indoors. But the material is located between the lags, since it does not withstand a significant load. But it has improved sound insulation properties, which is important when arranged overlapping between residential premises.
PZ175. The heat insulator based on mineral fibers, which in addition to high density is characterized by increased rigidity. It is used for the insulation of overlapping the base or attic on the reinforced concrete plate.
PPG200. Material similar to the previous on its operational properties and application. However, due to increased fire protection properties, it can be used to design fire prevention partitions.

In conclusion, I will give a few tips to which I myself use when acquiring a fibrous insulation for overlapping:

Prefer the materials produced in the European Union. There are very high demands for certification, so you can not doubt as and security.
If we talk about firms, I prefer such as Ursa, an escape, Rockvul. The cost most often depends on the density of the insulation, since more raw materials leave for the production of a more dense heat insulator.
Do not chase for cheap and do not buy glass gamble and slag. They are not only less effective for insulation and sound insulation, but also create you many problems during installation.
When buying, specify how the insulation fibers are located. There are two options here:

strictly vertically oriented - the material will have excellent heat and sound insulation properties;
oriented chaotic - the product will be more durable and well transfer dynamic loads.

Check that the material packaging it is indicated that it meets the requirements of GOST RUSSIA. For these insulation, there are several regulatory documents: 9573-96, 21880-94 and 22950-95.
Make sure that the sizes of thermal insulators declared on the package correspond to reality.. To do this, I advise you to simply break the polyethylene in which the plates are wrapped and measured their ruler.

Slave insulation

Now I will tell about another category of insulation for floors - slab. I also often faced them in the process of work. They are especially popular with beginner builders due to simplicity of installation.

When you start talking to someone about the slab insulation, you immediately hear the mention of the foam. And all, using this term, imagine porous and lightweight material, from which every boy built a boat in childhood.

However, in fact, foams are a whole group of insulation materials produced from polymer foam. And specifically, two types of foams are used for the insulation of overlaps - polystyrene foam and polyurethane foam. It is them that I will describe in more detail below.

Polystyrene foam

A rather inexpensive insulation, which is sold in every construction store and is used almost in every second construction. The polystyrene foam is made from a special polymer, but use different technologies for this. As a result, several insulation are present on the market, the technical characteristics and operational properties of which are quite different.

You can learn more about this from the table.

Name	Abbreviation	Properties
Interceptable suspension	PSB	Material with a homogeneous internal structure and various density, which determines its operational properties. There is a polystyrene brand from 15 to 50. The smaller the density, the more heat-grinding properties, but worse the strength. For insulation, it is better to buy material with the Marking of PSB-C, which fades during a fire and does not contribute to the spread of the flame.
Pressed expanded polystyrene foam	PS.	It is distinguished by increased hardness, strength and hydrophobic properties. In contrast to the previous variety, there is no capillary system in this insulation, and the granules are complined. It is not enough for the insulation of overlaps, as it has a high cost. More suitable for the manufacture of multilayer insulation panels.
ExtrudedPenopolistic	Epps Xps.	The most efficient slab insulation from those I know. It is manufactured by complex technology when the foamed raw material is made through special devices, forming the plates of the heat insulator. The material has a low thermal conductivity coefficient and high strength. It can be laid under the tie of the floor without reference lag, that is, to warm the overlaps that will serve as sex.

Polyurene Foolder

Typically, polyurethane foam foam is applied on the surface with a sprayer, but on the market of heat-insulating materials I met both the plates from this material. They are soft, elastic and solid. The density of the insulation is between 20 to 200 kilograms per cubic meter, that is, the heating protection properties differ.

The slab polyurethane foam has a closed cellular structure, so no moisture is afraid. However, it does not withstand the direct exposure to sunlight and disintegrate.

But other technical characteristics at the height:

the material has a zero level of emission of chemical compounds, so it is safe for health;
not susceptible to biocorrosion;
perfectly transfers mechanical effects.

Benefits of slab insulation

The biggest plus of this category of thermal insulators, in my opinion, is the simplicity of installation and its speed. This reduces the cost of insulation of overlaps and reduces the construction time.

On the other hand, they cannot be put on overlap without seams, which often become the cause of unproductive heat loss. However, if you clearly adhere to technology (I repeatedly described ways of insulation with the help of polystyrene foam and EPPS), this problem is possible to avoid.

Bulk insulation

There are several types of thermal insulation materials of this category, significantly different from each other with their technical characteristics. I'll tell you about those with whom most often had to deal.

Foamflast crumb

This insulation is polystyrene granules that are not glued together. The essence is that when gluing the granules, the density of the material increases, and the heating protection properties are falling.

And if the insulated surface is simply filled with granules, there will be more air between them, which increases the efficiency of the material. But simultaneously with a decrease in density, durability falls, which is not always acceptable.

Therefore, I advise foam granules to warm the overlap of the already built dwellings in the event that you need to fill some hard-to-reach places or density. And you need to fall asleep it is not a shovel, but a compressor that will help to make the granules more densely and reduce their shrinkage.

With huge disadvantages of this insulation, I consider bad fire prevention properties and the possibility of damage to rodents.

Bulk foamisol

If you glance, this material is very similar to the scattering foam, but the attentive person will notice that both the structure and the properties are completely different.

Differences of foamizole are as follows:

separate elements of the insulation resemble not round granules, and snow flakes;
material is softer to the touch.

Used to insulate inter-storey overlaps and walls. Unlike foaming, it does not burn and does not distinguish dangerous combustion products into the air.

Plus, foamizol also in the fact that he albeit through himself moisture, but does not absorb her. Therefore, the material always performs the functions assigned to it and does not interfere with the air infiltration through the enclosing structures.

Granulated foamglo

Insulation, which is made from a glass battle. In the process of production it is melted and mixed with coal. Under the influence of temperature, carbon dioxide is distinguished from the latter, which, after frozen, gives the glass porous structure.

The material comes in the form of granules or rubble and has the following characteristics:

absolutely does not absorb moisture;
not susceptible to burning
has a low thermal conductivity coefficient (from 0.04 to 0.08);
withstands very large mechanical loads;
it can be operated at temperatures from - 250 to + 250 degrees Celsius.

I used this material as a filler for concrete, which flooded overlaps. As a result, the screed acquired heating protection properties without additional labor.

The main minus of this insulation is a very high cost. In private construction, it is practically not used precisely because of this. Although the advantages are even debugging.

Ceramzit

This material manufactured from clay by firing is known from time immemorial. It is sufficient sufficient, is durable and has good heat grumbling properties. It can be used to insulate horizontal surfaces, including under load.

To the advantages of this type of insulation, I can attribute:

the infertility of biocorrosion - mold and fungi does not appear in the insulation layer, rodents do not come;
high fire prevention properties - the material does not ignite and does not contribute to the spread of fire;
absolutely safe for health - has zero emissions of substances harmful to humans;
it does not enter into chemical reactions with other substances - that is why it can be used as a filler for concrete.

The minus is that although the ceramzite and badly absorbs moisture, he gives it to the same reluctance. And the wet insulation, as you understand, it copes much worse with the tasks assigned to it.

Ekwata.

The heat insulator, which is developed by European specialists as a method for utilizing waste containing cellulose fibers. The insulation of newsprint with a small addition of cardboard is made. In order for the material to comply with fire safety requirements in it, anti-epires are added.

It is not only horizontal interhent floors, but also walls. It is applied using a compressor or manually. Depending on this, the density changes - from 45 to 90 kg per cubic meter.

The material does not have high hydrophobic properties, but when wetting quickly dries. In this case, the insulation gives shrinkage, which reduces its thermal insulation properties.

Another minus is a short service life. Taking into account the climatic characteristics of Russia, it is up to 10 years. Therefore, personally, I advise you to use alternative options.

Perlit

Material, which, like basalt wool, has volcanic origins. Perlite ore during the processing process is heated to 1000 degrees Celsius, due to which the excess moisture evaporates. In the process of this, perlite acquires a porous structure.

The insulation laid in the overlap perfectly protects the room from heat loss, but does not prevent air infiltration. It completely fireproof and chemically neutral.

The material density ranges from 60 to 100 kilograms per cubic meter, so the thermal conductivity coefficient is from 0.04 to 0.05 W / (M * K).

To facilitate installation, frelitis granules are mixed with bitumen mastic. As a result, the material becomes adhesive and easily placed on any surfaces, not even horizontal. After the frozen, a seamless heat-insulating layer is formed, which perfectly retains heat indoors.

Vermikulitis

It is made of mica minimized by a career way. At the plant, the raw material is crushed into a crushed stone fraction, which heats up to 700 degrees Celsius. As in the case of perlite, the foaming of the mineral occurs, due to which the granules become porous.

The huge plus of this material is the unlimited service life. In the manufacture of the insulation, the glue or any chemical compounds that can be spoiled during operation.

As for the rest of the technical characteristics, they are also at the height:

the density ranges from 65 to 150 kg per cubic meter;
the coefficient of thermal conductivity - from 0.048 to 0.06 W (M * K);
has fire protection properties;
does not highlight hazardous chemical compounds;
does not prevent air infiltration.

Vermiculitis well distributes moisture inside insulation layer. That is, with a moisture of a section of overlapping, warmed by vermiculitis, it will dispense the fluid inside, and the general heat grumbling properties will not change.

The cost of vermiculite is quite accessible, so it can be used in private construction for the insulation of the attic and basement overlaps.

Sawdust

I am not a supporter of this insulation, but I can not mention him. Although the material and has a low thermal conductivity, it is better not to use it, since it is not enough that it absorbs moisture, it also rotates.

clay;
clamzit;
vermiculitis;
perlit.

In this case, water pairs, falling into sawdust, are discharged through the insulation listed above.

But there is one point. Very small sawdust are suitable for insulation, which are formed when processing a tree on modern high-breeding machines. And it is not so easy to get them. Consequently, do not fool your head and use other materials. Especially since I called you more than enough.
