Insulation of a frame house with mineral wool - a diagram and a step-by-step description of the work. Instructions for insulating a frame house with your own hands Insulation of the walls of a frame house with a mineral

Frame houses are becoming increasingly popular, however, this European trend in the Russian climate requires significant thermal insulation, as well as protection from wind and moisture. Experts recommend insulating walls frame house not only from the outside, but also from the inside.

Choosing materials for thermal insulation

A few decades ago to keep the heat in the house in the walls frame houses covered with a mixture of clay with straw, sawdust or shavings. At one time, sawdust concrete was also popular, but these materials have long been out of use, although they do not lose their attractiveness due to their low cost. V modern houses on the basis of the frame for insulation, mainly mineral wool (glass wool, stone wool) and polystyrene are used.

Mineral wool has a number of advantages - they are fireproof, which is especially important for houses made of wooden frames, have low thermal conductivity, are easy to install, are produced in a form convenient for builders (mats, rolls) and are quite light. The disadvantage of this insulation is that it cannot be called environmentally friendly, since it contains formaldehydes in small doses. In addition, moisture is contraindicated for him. Most often, mineral wool is used for external insulation, because for internal works using this material is not always convenient and safe.

Very quickly, among building materials, foam plastic broke out into the category of the most popular materials for thermal insulation. It is made from granules of polymer plastics, which are filled with carbon dioxide or natural gas.

Styrofoam boards are very light, easy to install, do not conduct heat and are environmentally friendly at normal temperatures. Insulation of this kind is not subject to rotting and the appearance of fungus, therefore, during its installation, additional layers of vapor and waterproofing may not be required.

Perhaps the most important advantage of polystyrene is its modest cost. Its main disadvantage is the possibility of ignition and the release of substances harmful to human health during combustion. True, there is a fire-resistant version of this material - extruded polystyrene foam, which is also more compact.. All types of polystyrene, oddly enough, can easily be spoiled by rodents, which is another significant disadvantage.

Polyurethane foam (PPU) is a sprayed type of thermal insulation that has the most a high degree heat retention and very resistant to moisture. Spraying occurs with the help of special equipment, in which the active components are mixed and, falling on the surface, instantly foam, forming a dense crust. You can spray PPU on almost any surface, even on glass and metal, regardless of its position. The vulnerable point of polyurethane foam is sunlight. When exposed to direct sunlight, its life is reduced by about half. But you can protect PPU from the sun regular painting. Another disadvantage is that special equipment is needed to work with this material.

For hydro and wind insulation, builders often use glassine - thick paper impregnated with bitumen. However, its use as a protection against moisture and wind is undesirable, since glassine does not allow moisture coming from the house to pass through and contributes to its accumulation inside the frame. In modern practice, builders are increasingly using superdiffusion hydro-windproof membranes, which have a huge vapor permeability compared to glassine and perfectly protect the house from wind and moisture from the outside.

Insulation of the walls of a frame house from the inside - preparatory work

First, let's clarify some basic principles, without which the insulation of the walls of such a house can be a waste of money. First, when wondering how to insulate a frame house from the inside, you need to think not only about the walls. The floor and ceiling can also let in the cold! Secondly, heat-insulating materials must be reliably protected from external moisture and internal waterproofing. Thirdly, during the process of laying the insulation, it is important to observe the gaps necessary for ventilation between the material and the wall surfaces.

Before starting the installation of insulation, clean the walls, floor and ceiling from dust and dirt. Any protruding nails or screws should be removed. The existing gaps between the frame elements of the house are filled mounting foam. Via building hair dryer if necessary, dry the damp areas of the frame.

The website site masters have prepared a special calculator for you. You can easily calculate the heat loss of a building.

How to insulate a frame house from the inside - step by step instructions

In the event that external thermal insulation with the use of waterproofing was nevertheless carried out in the house, it is not necessary to re-mount another layer of moisture protection inside the house, otherwise this may lead to the accumulation of excess moisture inside the structure and its rapid destruction. We will consider the option of warming the house only from the inside.

How to insulate a frame house from the inside - step by step diagram

Step 1: Installation of the waterproofing layer

We measure the walls of the frame house and cut into the appropriate strips the one we have chosen waterproofing material. Via construction stapler we fasten it to the racks, completely sheathing the frame. It is best to lay the waterproofing with an overlap, leaving under upper layer about 10 cm. Fastening is carried out at the junction every 10 cm.

Step 2: Installing the vapor barrier

Even in the case of using materials that are not afraid of moisture as a heater, it is still necessary to perform a vapor barrier. The reason for seemingly unnecessary costs at first glance is that, in addition to the insulation itself, there are other elements in the wall frame that should be protected from steam penetrating from the inside of the building into the walls, for example, the same wood.

For vapor barrier use special film or polyethylene foam. This material is also attached to the racks of the frame with a construction stapler close to the insulation. Sometimes builders simply wrap heat-insulating blocks in such a film, but this is not entirely correct - as already noted, all elements of the frame must be protected from steam. The joints of the film, as in the case of waterproofing, should be made with an overlap of at least 10 cm. For greater vapor barrier, all joints and junctions of this layer should be glued with double-sided tape. When installing a vapor barrier, please note that its thickness does not in any way reduce the thickness of the main insulation.

Frame house insulation- one of the most milestones construction, since the insulation layer serves as the only barrier to the penetration of cold into the dwelling, as well as an insulator from wind and moisture.

AND up to 80% all frame houses are insulated with mineral wool or materials based on it.

Mineral wool- This is a vapor-permeable insulation, which is the most popular material for thermal insulation. Minvata is distinguished by high sound insulation and environmental friendliness. Throughout the entire period of use, the mineral wool remains in its original form.

Advantages and disadvantages

Main advantages mineral wool:

• Low thermal conductivity. This coefficient depends on the density of the mineral wool and can range from 0.032 to 0.039 W / (m * K). And the harder the wool, the less thermal conductivity it will have.
• Durability. At correct installation insulation can last up to 70 years.
• Ease of installation. The material is easy to cut with a knife and is convenient to process.
• Fire safety. Mineral wool does not burn, but only melts under the influence of high temperatures without releasing harmful substances into the atmosphere.

To disadvantages insulation mineral wool include:

• High cost.
• The need to protect the material from moisture using a vapor and waterproofing film.
• Installation of wool slabs must be carried out in a suit and a respirator to protect against harmful dust .

Types of mineral wool, their pros and cons

It happens 3 types:

• Glass wool (raw materials are glass melts).
• Stone (made from rocks).
• Slag (made from slag).

Previously described advantages and disadvantages mineral wool are inherent in all its varieties, the following shows the distinctive pros and cons of each type.

glass wool- This is a fibrous insulation, which is one of the types of mineral wool. The raw materials for its manufacture are glass melts and binders- resins.

Advantages of glass wool:

• Breathability.
• Frost resistance.
• Chemical resistance.
• Resistant to mold and fungal attack.

Cons of insulation:

• Short service life - up to 10 years.
• Shrinkage up to 80%.

Stone (basalt) wool is a vapor-permeable insulation, which is one of the best sound and heat insulating materials. It is made from rocks with the addition of carbamide resins and bentonite clay.

Advantages of stone wool:

• High density.
• Minimum shrinkage (about 5%).
• Resistant to decay, mold and mildew.

To disadvantages can be attributed to the high moisture absorption of stone wool.

Important: cotton wool is produced in slabs and rolls, it can have different density - from 30 to 100 kg / m³.

slag wool is made from blast-furnace slag, which is a waste of metallurgical industries.

Advantages of slag:

• flexibility and elasticity (can be used for warming rounded surfaces).
• Low cost.

Cons of insulation:

• When water gets on the cotton wool, an acid is released that destroys the metal.
• The material does not tolerate temperature extremes.

The table shows that stone wool has the very best technical indicators, plus everything has a minimum shrinkage. Slag wool is noticeably inferior to glass and stone wool in terms of thermal conductivity and has low sound insulation performance.

Frame house floor insulation technology

floor insulation technology based on the type of foundation of the house. Majority frame structures put on pile screw foundation, but regardless of the type of foundation of the house, the first layer of floor insulation should be waterproofing.

If the house is located high from the ground and you can climb under it, then under the logs from below they are first attached with a stapler waterproofing film and then nail the bottom cladding boards.

They can be nailed close to each other or in increments up to 40 cm. They will keep the mineral wool slabs and the waterproofing film from falling down.

If you can’t crawl under the house, then boards are stuffed under the logs, and then a film is laid on top of the logs and boards from the inside. Mineral wool fits tightly between the lags on the film . Distance between lags should be 58-59 cm, because standard width wool slabs - 60 cm.

Average mineral wool layer thickness should be 15 cm, and the height of the lag is slightly less. Each new layer of wool must overlap the joints of the previous one and have an overlap of at least 20 cm.

Over mineral wool and lag attach vapor barrier film, the joints are glued with 2-sided tape. Sheets of plywood, OSB or boards are laid on the film, which will serve as the basis for fine finish floors.

Important: hydro and vapor barrier films are laid so that their edges go onto the walls. This will prevent moisture from getting between the wall and the floor of the frame house.

Scheme of wall insulation of a frame house with mineral wool

Walls in frame house warm and outside and inside. The materials used for this are the same.

Insulation of external walls

wall insulation technology mineral wool outside includes several stages. First, the frame is sheathed on the outside with OSB boards with a distance between the boards of 2-3 mm. Then these slots are filled with mounting foam.

Outside, a waterproofing film is stretched over the plates to protect boards and a layer of mineral wool from precipitation, the joints of the films are double-sided tape.

WITH inside mineral wool slabs are inserted between the frame bars. The joint of the second layer of wool must overlap the joint of the first by 15-20 cm.

Advice: it is best to take wool slabs with a density of at least 35-50 kg / m³ to insulate the walls of a frame dwelling. Such a mineral wool will not sag and roll down.

After installing all insulation must be completed mounting foam all the cracks that appeared at the junctions of boards and beams.

Over a layer of mineral wool a vapor barrier film is stretched from the inside to protect the insulation from moisture coming from inside the room. Next, OSB sheets, plywood or boards are stuffed onto the film. In conclusion, finishing walls.

Insulation of internal walls

Warming internal walls frame house is mainly carried out to provide sound insulation. To do this, you can use mineral wool, another type of insulation or special soundproof materials.

The technology of wall insulation inside is similar to insulation external walls, while hydro- and heat-insulating films may not apply.

Ceiling insulation with mineral wool

Ceiling insulation is one of the most important stages of home insulation technology. It is recommended to carry out it while the roof is not yet fully assembled, so that it does not interfere with the dense laying of mineral wool on top of the ceiling.

First, on ceiling beams a vapor barrier film is attached from the inside. A board is nailed to it 2.5 cm thick, plywood sheet or OSB board. Further, wool slabs are attached from above according to the same rules as for wall and floor insulation.

Attention: mineral wool is placed completely along the entire ceiling, plus an overlap for the entire width of the walls.

If the attic is not used for living, then there is no need to lay membrane films. You can immediately sheathe it with plywood or board for ease of movement. In the case when it is not possible to insulate the ceiling from above, it is applied insulation from the inside. For this, mineral wool slabs are tied to the ceiling. Then a vapor barrier film and plywood sheets or boards are sewn.

Because warm air always goes up with illiterate insulation the ceiling from the room will leave a large amount of heat.

Insulation of the roof of a frame house

roof insulation technology similar to ceiling insulation with one exception. A waterproofing film must be laid on the insulation layer to protect the mineral wool from external environment(rain, wind or snow).

After installation truss system a vapor barrier film is hemmed from below, on which hemming boards or plywood sheets are stuffed from the inside.

Then sheets of insulation are laid outside, covering them with a waterproofing film. On film stuffing the counter-lattice, then the crate under the roof and the roofing material itself.

Roof insulation it is more convenient to produce outside, so the cotton fibers will not fall on the face. If the roof is already assembled, then the insulation can be made from the inside. But this is less convenient, since it will be necessary to temporarily fix the mineral wool slabs before pulling the vapor barrier.

In conclusion, we can say that the insulation of a frame house with mineral wool will ensure minimal heat removal through the walls and cut costs for heating in winter. Mineral wool as a heater provides natural ventilation in the house and is an excellent sound insulator from noise from the street.

See the video for the insulation scheme of a frame house with mineral wool:

Master class on warming the external walls of a frame house using URSA TERRA, see no video:

Today, frame houses are gaining popularity in Russia. They are built of wood on the basis of a wooden or metal frame. Typically, such a frame is either erected at the factory or directly in the construction area. Plasterboard, chipboard or other materials are mounted on the frame. It is from these materials that the walls of the building are created. One of their disadvantages is poor thermal insulation. This problem can be solved with the help of varieties of foam or mineral wool. We will talk about the latter in this article.

general information

Mineral wool - synthetic substance, which consists of a number of fibers of inorganic origin. Such fibers may be broken glass, dolomite or basalt. They are created by melting the substances described in the previous sentence and then loading them into a centrifuge. In the centrifuge, under the influence of high speeds, the molten substances cool down, stretching into strong fibers, which are pressed into plates or rolled into rolls. That the first, that the second option is ideal as a heat-saving material that can be used to insulate the walls of a building and not only.

Insulation of a frame house with mineral wool is beneficial due to the fact that it has high thermal insulation characteristics, it is inexpensive, and its installation does not require much work. The high thermal insulation capabilities of this material are explained by the fact that there are many air chambers in the structure of the mineral wool fibers, which make up approximately 90% of this structure. Thanks to these chambers, which are a fairly dense layer, the material retains heat inside the building and does not let the cold in from the outside.

Since mineral wool is a synthetic raw material, it can have one of the following fiber structures:

• corrugated
• spatial
• vertically layered
• horizontally layered

Regardless of the type of fiber structure, this material is able to perfectly withstand the influence of high temperatures, as well as the effects of many chemical substances. In addition, it has high ductility, which is extremely convenient for builders in the process of laying it.

Among the minuses of mineral wool, one should highlight the presence of formaldehydes in its composition - gases harmful to the human body. To protect themselves from their harmful effects, mineral wool is produced in the form of special pressed plates. After installation, they are trimmed vapor barrier membranes, which do not allow formaldehyde to penetrate inside the building.

Another minus this product- its increased moisture sensitivity. It is not in vain that a layer of a special waterproof film is then laid on top of the mineral wool, which protects the material from moisture ingress, which can damage its structure and significantly reduce its thermal insulation capabilities.

Varieties of material

Mineral wool is divided into the following three types:

No. p / p	Material type	Peculiarities
1.	glass wool	Made from fiberglass. Differs in the special durability and elasticity. When installing it, you must use special means personal protection(overalls, gloves, etc.) so as not to get hurt by glass microparticles.
2.	slag wool	It is made on the basis of blast-furnace slags. The thickness of its fibers is higher than that of glass wool. Absorbs too much moisture, which is why it is not suitable for insulation metal surfaces, For example, water pipes. Suitable for warming frame houses.
3.	Basalt (stone) wool	The thickness of the fibers is about the same as that of slag wool. The material does not prick, so you can work with it without using personal protective equipment. It has high temperature stability - it is able to maintain its properties in the temperature range from -190 to +1000 °C.

Each of these three types is perfect for insulating a frame house. but Special attention should be given to slag and basalt wool. Due to the fact that these two types have a thinner fiber structure, their density is higher, and accordingly they retain heat better than glass wool. In some cases, glass wool is cheaper. It is possible to insulate a frame house with this type of mineral wool, however, in order to achieve the same effect as in the first two options, the layers of glass wool must be wider.

To achieve a comfortable stay in the house during winter period it is necessary to think about insulation even at the construction stage. This will prevent the penetration of cold air into the room and ensure compliance with the temperature and humidity conditions. Insulation of a frame house can be done by hand. Step-by-step instruction for each type of structure is given below.

Why is it necessary to insulate the house

With the help of thermal protection of structures in contact with cold air, the following problems can be solved:

• condensation from inside the premises;
• the appearance of dampness, mold and fungus;
• increase in heating costs;
• non-compliance temperature regime living quarters and reduce the comfort of living in it.

In addition, a competent technology for warming a frame house can extend the life of the main structures of the building.

Materials for thermal protection

Home insulation can be carried out using the following materials:

• mineral wool;
• extruded polystyrene foam;

Types of mineral wool

There are two classifications this insulation. The first is based on the raw materials used to make:

• basalt;
• glass;
• slag.

The most popular is the insulation of the walls of a frame house and other structures with basalt mineral wool.

The second classification is based on the form of insulation release:

• rigid boards;
• roll material.

It should be noted that glass wool is produced only in rolls.

Rigid slabs that can withstand fairly high loads are suitable for floors. Insulation of the walls of a frame house can be carried out using both plates and rolls. For mansard roof it is best to use slab material. This will allow you to easily insulate with mineral wool between the rafters.

Insulated frame house structures

Before insulating a frame house, it is necessary to decide which structures require this additional event.

With your hands you can protect from the cold the following elements building:

1. the floor of the first floor;
2. attic floor (if the attic is cold);
3. mansard roof;
4. exterior walls.

Do-it-yourself insulation work can be carried out both outside and inside. It is best to mount the insulation between the studs as this will ensure competent work material. Warming wooden house mineral wool from the inside of the wall will greatly simplify the work and allow you to hold events in all weather conditions.

Double-layer insulation - a guarantee of 100% thermal protection

An external insulation scheme is possible if the insulation from the inside is not sufficient and additional insulation is required. Peculiarities:

• outer thermal insulation material must not create a vapor barrier. Otherwise, the resulting condensate from water vapor will accumulate between the two layers of insulation, which is fraught with the formation of mold and mildew;
• house wall thickening

Based on the foregoing, it follows that the thermal protection of a wooden house from the outside with mineral wool should be carried out only in exceptional cases, when the scheme from the inside is not applicable.

Wall insulation

Double layer insulation (double frame)

To guarantee a comfortable stay during the winter period, it is important to take care of the thermal protection of the walls. To reliably insulate the walls with basalt or other wool from the outside with your own hands, you need two-layer insulation. Follow the following layer order:

1. interior decoration;
2. vapor barrier;
3. mineral wool insulation (2 layers with offset racks);
4. windproof membrane;
5. OSB-3 on the crate;
6. exterior decoration of the facade.

It is important to remember that the scheme for using this type of insulation requires the obligatory presence of a ventilated layer with a thickness of at least 4 cm. This is necessary due to the high hygroscopicity of the material. In order for the insulation to retain its performance characteristics, it is necessary to remove excess moisture from its surface. This is ensured by the circulation of cold air outside the surface of the mineral wool.

Most often, the technology for insulating the walls of a frame house is the following scheme: the material is not laid on any side, but between the racks of the frame. This reduces the overall thickness of the wall and significantly reduces the construction time of the building. Mineral wool is fixed between the racks of the frame, after which sheathing is performed on both sides.

Vapor barrier and wind protection during do-it-yourself work are located similarly to the previous cases: steam protection from the inside, and wind protection from the outside.

With thermal protection of the walls from the inside under hinged facade The layer order is as follows:

1. interior decoration of the premises;
2. vapor barrier;
3. mineral wool;
4. superdiffusion membrane;
5. wall construction;
6. facade decoration.

Floor insulation

For a wooden frame house, overlappings along the beams are characteristic. When arranging thermal insulation with your own hands, insulation boards are placed between load-bearing structures overlap. You can also use rolled materials, but for their spreading, you will need to pre-install the lower crate or solid flooring.

When insulating with mineral wool in the form of rigid slabs, the step wooden beams it is better to take overlaps so that 580 mm remains clean between them. This will provide maximum convenience work with plates with a width of 600 mm and complete filling of the space with heat-insulating material.

When doing activities with your own hands, you need to remember that the vapor barrier is located from the inside of the room, and the waterproofing is from the cold air side. In the case of intermediate floors, steam protection should be provided from the side of the ceiling.

Warming attic floor

It is also important to remember that when working with any type of mineral wool, it is better to prevent particles of the material from getting on the skin and into the lungs. For this, it is best to use gloves and a mask. Also, workers must have special clothing that completely covers the arms and legs.

Pitched roof insulation

Do-it-yourself installation technology is similar to ceilings. The pitch of the rafters, as in the previous case, is selected with respect to a clear distance of 580 mm.

Work is performed in the following order:

1. installation of the truss system;
2. laying a waterproofing layer over the rafters;
3. thermal insulation;
4. installation of vapor barrier;
5. upper and lower crate;
6. laying roofing material;
7. ceiling interior trim.

Preparatory work

Before properly insulating a frame house, it is necessary to prepare the surfaces. To do this, perform simple actions:

1. processing of all structures of a wooden house with the help of antiseptic compounds to prevent damage to them by various microorganisms;
2. cleaning the surface from dirt and dust;
3. elimination of significant inconsistencies.

These simple do-it-yourself manipulations will provide the insulation with a reliable connection to the structures and the longest possible long service life.

In contact with

Construction of a frame house - a process of sequential phased creation all structural elements of the building.

Wherein the order of work is strictly defined, changing or violating the sequence of actions is impossible - all operations are interconnected and logically follow one from the other.

Proper insulation of a frame house is not a separate event, carried out whenever possible or desired. This obligatory part technological process, one of the stages of construction.

Thermal insulation for the walls of a frame house is a fairly simple process, but responsible and requiring a clear understanding of the physical meaning of the actions. Its peculiarity is that no trifles that can be dismissed are not recognized - any shortcomings are equated to serious violations of technology, leading to the failure of many elements of the wall structure. Let's consider the issue in more detail.

Requirements

Insulation - component frame house wall systems. Is not additional measure, which enhances the overall functionality, and a regular component of the design.

Little of, the walls of the frame house are almost entirely composed of insulation- it accounts for 3/4 of the volume of all materials.

In addition, the insulation is the main part of the wall, all other elements, in fact, solve the issues of structural rigidity and protection of the material from moisture and maintaining its working qualities. The importance and responsibility of the tasks performed put forward to insulation material a number of requirements:

1. Low thermal conductivity.
2. Low density, light weight.
3. Lack of reaction to the appearance of moisture, low (ideally - absent) hygroscopicity.
4. Shape stability, no shrinkage or swelling of the material.
5. No harmful emissions such as formaldehyde, phenol, etc.
6. The composition of the material should not contribute to the appearance of insects or rodents.

In addition to the above properties, an important quality of insulation is rigidity. Some types of materials are produced both in a rigid state (slabs) and in a liquid state, requiring special equipment for application, which greatly complicates the workflow and requires experience and skills. For independent work much more convenient materials that do not require the use of additional equipment.

The main types of insulation

The list of materials that are used for thermal insulation of frame walls is quite wide.

Are issued in the form of plates, rolls, granules, powder.

The main groups of insulation by origin:

1. Mineral. Basically, these are various melts of minerals, slags or glass, technologically converted into cotton wool - mineral wool, glass wool, slag wool, etc.
2. Natural. This group includes various modifications sawdust or shavings (wood concrete, chip concrete, etc.), wool, ecowool, reed mats, etc.
3. Synthetic. Various materials obtained by chemical means, for example - polystyrene foam, polystyrene foam, polyurethane foam, isofol, etc.

As a rule, in practice most often they insulate the frame walls with mineral wool and polystyrene foam. For this use different types mineral wool, glass wool or synthetics - polystyrene foam, polystyrene foam, etc. They are reliable, lightweight and do not load the wall frame too much, in addition, insulating the walls in a frame house with your own hands is quite a feasible task.

Tools and means of protection

The method of installation of the material largely depends on its properties and the form of release..

Some are easy enough to accurately cut into the shape of the gaps between the stepping posts, others require special equipment and protection.

For independent work, heaters are usually used, which allow installation with minimal use of equipment and protective equipment. However, if glass wool is used as a heater, elementary protection will be required. To work, you may need:

1. O sharp knife. Shoe shoes will not work, since the insulation can be up to 200 mm thick. You need a knife with a fairly long blade.
2. Mounting foam. Excellent tool for sealing cracks and gaps.
3. Hammer, small nails, thick thread. All this is useful for temporarily fixing the insulation in the nests.
4. Putty knife. It will help to tightly plug the material into the cracks.
5. Latex gloves. When working with prickly materials such as glass wool, they are indispensable.
6. Respirator. Inhalation of dust and small particles of insulation can lead to various diseases, so respiratory protection will not hurt.

Often when working with insulating materials use a full protective suit covering the entire body and face. The measure will not be excessive when using liquid spray materials that create a suspension in the air and can get on the skin, hair or clothing.

Preliminary preparation

The insulation is installed on a wall frame fully prepared for this.

At the time of installation, the following items should be ready:

1. Fully assembled - racks, and top trim, jibs and other elements.
2. Installed outer skin from OSB, chipboard, plywood or similar sheet materials.
3. A waterproofing membrane (or other roll-type waterproofing) is installed, all joints are connected with adhesive tape, there are no gaps or cracks.

That is all operations that cannot be carried out with the insulation installed must be performed, and then the walls of the frame house will be insulated from the inside. If it is produced by the platform method, that is, in a supine state, then the insulation is attached only after the wall has been lifted and aligned with the markup.

Technology

How to properly insulate the walls of a frame house? How to properly install insulation frame walls? As mentioned above, there are several types of insulation. The scheme of warming the walls of a frame house for each of them has its own characteristics. Consider one representative from each species.

Mineral wool

Frame houses: wall insulation with mineral wool for such prefabricated structures is very common. It is best to choose basalt slab wool.

It has sufficient rigidity and does not lose its shape during installation. The thickness of the slab is chosen so that it corresponds to the width of one or more layers.

Important! The insulation should not be thicker than the width of the racks!

Insulation of the walls of a frame house with mineral wool is carried out as follows:

1. Primarily, a waterproofing layer must be installed. stripes roll material fastened in horizontal rows, starting from the bottom. Joints are isolated with special adhesive tape.

2. Mineral wool slabs are cut into pieces, exactly matching in width to the nests of the frame.

3. The cut pieces are inserted into the slots. If necessary, tuck the edges with a spatula.

Attention! Work with a spatula or similar tools must be done carefully, do not damage the waterproofing layer!

4. The installed parts of the insulation are fixed in place with thick threads thrown in loops over small nails driven into the racks. If there is no desire to spoil the hydroprotection layer with nails (and this is inevitable), then it is necessary to cut and install the insulation boards as accurately and tightly as possible.

5. The joints of the pieces of material are glued with special adhesive tape. As an option - sealed with mounting foam. There shouldn't be any cracks.

6. Over fully installed insulation a layer of vapor barrier is attached. Its installation is carried out similarly to waterproofing - horizontal rows, starting from the bottom, the rows are overlapped by at least 150 mm, the joints are reinforced with adhesive tape.

All layers of the cake must be airtight, without cracks, holes or other violations.

Important! Even a small hole or gap will definitely cause materials to get wet and wood to rot!

Styrofoam

First of all, it is necessary to choose the thickness of the material plates in order to provide the most favorable ratio of the thickness of the insulation and the width of the racks.

If necessary, you can use a combination of several plates with different thicknesses.

Insulation of the walls of the frame house with foam plastic is done in the following order:

1. The first layer is roll waterproofing.
2. The material is cut to size. It is better to cut with a hacksaw with a fine tooth, trying not to crumble the material.
3. Installing foam in the nest. Bearing in mind the rather fragile structure, one should not use force to hammer a piece into the nest, it is better to cut it. You can temporarily fix it with small wedges.
4. All existing gaps and joints are filled with mounting foam.
5. After crystallization, the excess foam is trimmed with a knife.

Sawdust

Sawdust is a cheap and affordable material. They are mainly used as insulation. in the form of various compounds with cement binders.

In their pure form, they are too dangerous in sanitary in addition, they are prone to decay and easily absorb water.

In addition, the use of bulk materials for wall insulation is almost impossible, since it will not be possible to achieve the required filling density of the nests. The cavities that have arisen in the thickness of the sawdust will inevitably create cold bridges, which will completely disrupt the operation of the warming cake and cause the frame and sawdust to get wet. So you can only use derivatives - wood concrete or other plate material.

Insulation of the walls of a frame house with sawdust is carried out in the same way:

1. A layer of waterproofing is installed.
2. The plates are cut into appropriate pieces and inserted into the slots.
3. Slots, joints or gaps are filled with mounting foam, which is trimmed after crystallization.
4. A layer of vapor barrier is installed.

Important! The use of sawdust is a dubious decision as it favorable environment for insects or rodents, and they also rot and absorb water. The presence of such circumstances makes the use of sawdust the least good choice of all possible.

Useful video

How the walls of the frame house were insulated is additionally described in the video below:

conclusions

Self-installation of insulation usually occurs in conditions of limited tools and lack of proper experience and skills. Since it is very important to properly insulate frame walls, it is recommended to use the most successful types of materials that are not demanding on the availability of equipment and do not have serious restrictions during the installation process.
