We will understand the additional insulation of the finished facade of the frame house from the outside. Insulation of a frame house Insulation of an OSB house outside

The old system of building wooden and stone houses provided for a system of insulation during the construction process. Insulation was not singled out as a separate area of ​​work, it was carried out along with the construction of walls and was a matter of course. Now, the concern about how to properly insulate a frame house is the main one for builders.

The procedure for warming work

The building materials market does not suffer from a lack of insulation for walls, floors and ceilings. Each owner wants to choose something unusual, but natural and not harmful to health, so that it is thorough, long-lasting and inexpensive. The intensity of heat transfer greatly affects not only your health, mood and warmth in the house, but also the state of your wallet, as heating services become more important. Therefore, you most often have to insulate the frame house with your own hands.

Insulation is an inevitable process of any construction, the need to insulate floors and ceilings is caused by their very design feature.

This part of the work requires as much attention as the construction of the frame itself. can be produced using various technologies:

• along the outer wall, attic and subfloor;
• along the inside of the walls and along the ceiling;
• both outside and inside the house;
• uneven insulation of different parts of the building.

At the same time, there are various methods of work, using which the walls retain maximum heat in the frame house.

If the builders did not carry out the insulation work clearly enough, they will have to roll up their sleeves and finish, redo, bring the insulation “to mind”, starting from the walls and ending with the underground, or even with their own hands again. At the same time, it is important to systematically, purposefully and carefully insulate all the areas listed above. The ceiling is subject to denser insulation, and the insulation layer should be much larger than on the walls - by 25-50%. Close attention should be paid to both external and internal wall insulation, and floor insulation should not be ignored.

Types of insulation for a frame house

Wall insulation does not present any structural features or difficulties even for a non-professional. The only difficulty is the choice of insulation. Heaters are produced in two categories - on a synthetic basis and on the basis of natural ingredients. The most commonly used insulation materials for frame houses:

• expanded polystyrene;
• Styrofoam;
• ecowool;
• mineral wool.

which is subdivided according to the material of manufacture into:

• glass;
• slag;
• stone.

Expanded polystyrene has an aluminum layer, which significantly improves its thermal insulation. The foil gives it, in addition to increased thermal insulation qualities, also moisture and steam resistance. This technology allows you to reduce the thickness of the insulation, while maintaining the same properties. Produced in sheet and roll form. For wall stickers, it can be produced with a self-adhesive surface.

The main disadvantage of polystyrene, if outside, is the negative effect of sunlight, leading to its destruction. This insulation for outdoor use needs protection. This protection can be paint or plaster. Its advantages include a wide choice of material thickness, fire resistance and environmental safety.

Mineral wool gained its popularity due to not only good thermal insulation properties, but also excellent fire resistance and excellent sound absorption. This material does not shrink over time. Available in rolls and also in sheet format.

Ecowool is made from cellulose fibers. Valuable ecological cleanliness. When dry, it is rammed into the piers, and moistened with water is applied to the interframe gaps of the walls. The possibility of glass wool is used extremely rarely due to a number of serious drawbacks. These include the fragility of the fibers, resulting in the formation of glass dust, which negatively affects health throughout the entire period of operation. This type of insulation is subject to shrinkage.

Pitfalls in insulation

Mineral wool, made on the basis of slag, becomes aggressive towards metals when moisture enters, and it has a very low level of heat saving. Wool, which is based on basalt, stone wool is an excellent opportunity to insulate frame walls. Environmentally friendly, durable, with both good insulating properties in terms of thermal conductivity and vapor permeability, and excellent fire-fighting properties.

However, if there are good heaters on the market, the desire still runs into problems. They consist in the difference between the vapor, moisture and heat permeability of the insulation. Styrofoam, for example, has good moisture resistance, but its heat resistance leaves much to be desired, while mineral wool, on the contrary, has problems with moisture protection. That is, it is necessary to insulate the frame walls, having previously distributed the insulation according to the degree of resistance to various environments.

The use of mineral wool should be limited when warming the house from the outside or provide protection from moisture, otherwise the heat insulator can become a heat conductor. But on the other hand, the frame house must have air exchange with the external environment. Natural heat insulators are good in this regard, such as:

• clay;
• tyrsa;
• straw.

They carry out natural heat exchange, maintain the optimal mode of humidity in the room, and provide protection from noise. Being involved as a heater on, they clearly fulfill their functions, predetermined by nature itself. But working with them is a long and laborious process, unacceptable for our high-speed age.

To prevent the appearance of excess moisture and steam, as well as to effectively collect them, glassine is used. This old companion of wall insulation is attached inside the outer skin of the frame. It allows you to leave dry insulation, which performs the main function - heat retention. At the same time, a gap is necessarily left between it and the insulation to allow the glassine to dry and prevent the insulation from getting wet. The air layer, in addition, in itself will be a natural thermal protection, complementing the main insulation and creating a healthy microclimate in the house.

Frame houses are a multi-layer structure with a complex wall consisting of several materials. One of the main wall materials is insulated. Most often it is mineral wool or polystyrene, which is laid directly on the frame, between its timber. This is the so-called internal insulation. However, sometimes there is a need for additional external insulation of the house (outside).

Material selection

Despite the abundance of materials for insulation, the choice practically consists of only two options:

• insulate with foam
• insulate with mineral wool

However, a more expensive method - insulation with foam boards - is also used, you can watch a video about it at the bottom of the article.

Each of these materials has both its fans and its opponents.

Styrofoam for exterior decoration is chosen more often, and the reason for this is its moisture resistance. In our climate, where it constantly rains, then snows, then fogs cover - this is the best option. At the same time, foam sheets additionally protect OSB-plates, which close the frame wall cake.

Styrofoam does not change its shape and appearance even after a long period of time, it is easy to lay it on the walls, as it is light and does not require great physical strength.

And another plus is that it is easy to plaster a wall with foam.

Mineral wool is used less often, but this material is quite suitable for external decoration, especially if you used wool for internal insulation and decided to immediately order more material. When buying a large batch, many sellers offer a discount.

Mineral wool has one significant plus compared to polystyrene foam, and this plus concerns the safety of the residents of a frame house. Mineral wool consists of fibers that do not support combustion. For private housing, this is a huge plus, since fires, unfortunately, in summer cottages or in private sectors are not rare. Therefore, the insulation of external walls with mineral wool is an additional protection of the house from fire.

The disadvantage of mineral wool in this case is its accumulation of moisture, which it absorbs like a sponge. After some time, unprotected mineral wool loses its appearance, cakes, holes appear in the insulation. This can be avoided by external finishing, which will prevent water from entering the insulation, and thereby extend the life of the frame house.

We lay the foam

Styrofoam is a simple and lightweight material, and it is a pleasure to lay it. Especially if the walls of the frame house are even, and you have at least some experience with this material. First you need to choose the right foam in the store. There are a huge number of types that differ from each other both in the density of the insulation and in the thickness. Which foam to choose for warming the house outside?

So let's look at the dimensions first. They are standard and represent three size categories: 0.5x1 m, 1x1 m, 2x1 m. Small sheets are used to insulate small areas, for example, balconies, booths, etc. number of joints.

The density of a foam board is determined by the size of the air space between the foamed polystyrene beads. There is the following marking: 15, 25, 35, 50. If foam plastic 15 is also suitable for internal insulation of rooms, then for the insulation of the facade of a frame building, which is often exposed to adverse effects in the form of rain, snow and temperature changes, a material with a density of 25-35 is suitable kg/cu.m.

Mineral wool also has a different density.

When laying the foam in two layers, it is worth closing the gaps between the sheets of the first row with plates. Then the building will be especially warm due to the absence of cold bridges.

You can get acquainted with the technology of warming a frame house in more detail.

Step-by-step instruction

So, you decided to stop on the insulation of the frame from the outside, chose foam for this purpose and are you ready to start work? Then consider step-by-step instructions on how to insulate a building from the outside.

1. Façade cleaning. The cleaning of the facade includes the removal of all protrusions, dirt, chips. The surface of the wall must be put in order, it must be flat and smooth. If you are insulating a new house that did not have a finish, then the OSB boards themselves already have a flat and clean surface, so this step can be skipped. Doi with stucco finish also usually has smooth walls.
2. We install a level beam from below along the entire perimeter of the building, where it is planned to insulate the walls. This beam is the reference for laying foam boards. They put the first row of foam plastic on it so that the laying is on the same level.
3. Warming starts from the outer corner of the building.
4. We apply a layer of mounting foam on the slab around the perimeter without interruptions (it is advisable to draw two more lines cross-to-cross inside the perimeter). Mounting foam, on the one hand, creates a small layer of air between the wall and the foam, and it is hermetic, and on the other hand, ensures reliable fixation of the plate to the wall.
5. Additionally, we fix the plates with facade dowels with a large cap. Their second name is fungi. They exclude the displacement of the plates relative to the walls and provide additional fixation.
6. The joints between the plates must be carefully foamed.
7. Very soft material is easy to cut, so with the help of a construction knife we ​​adjust the size to insulate the place near the doorway or window.

We read more about the insulation of a frame house with polystyrene foam.

Thus, it can be seen that the process of insulating a frame building is not so complicated, and the work progresses faster if large sheets are used.

Step-by-step instructions for laying mineral wool

The step-by-step instructions for insulating a frame house with mineral wool have much in common with the instructions for insulating a frame building with foam from the outside.

1. The preparatory stage for leveling the walls.
2. Using a fishing line and a level, we nail a guide beam from below, on which we will put the first level of stone wool mats.
3. The insulation in the form of cotton wool is pressed against the wall with 75 mm self-tapping screws. Additionally, we fix the plates with washers (rondole) - fungi with a large hat. It is necessary to press tightly to avoid a gap between the wall and the insulation.
4. In order for the insulation to hold firmly, it is necessary to install a horizontal top bar and vertical bars in addition to the wall. The vertical bar is attached from above to the upper horizontal one, and from below it stands on the lower guide.
5. Between the bars, the insulation is inserted as tightly as possible. The rondol additionally fixes the cotton wool, for which not self-tapping screws are used, but 120 mm nails.

If you want to use rolled wool for external insulation, then first we fix it from above, using a beam, and then we unwind the roll down. We also fix cotton wool at the bottom. The crate will press the wool against the wall and fix it in one place. Inexpensive cladding will keep cotton wool dry.

A simple scheme for building a frame house has one weak spot. The warmth of the house directly depends on the amount of insulation in the wall frame, outside and inside. The right choice of materials, their installation and alternation will ensure warm winters and cool summers. Insulation of a frame wooden house from the inside must be carried out not only based on the climate in the region, but also on the architecture of the building.

Standard drawings of a frame house involve the construction of a building with several layers of insulation. As a rule, there are 2 of them: combined, based on mineral wool, and a thick layer of foam from the outside. However, for some types of climates, foam cladding from the outside is practically useless. To preserve heat, the house is insulated from the inside.

Frame house insulation: materials

To ensure protection from the cold of a frame building, it is necessary to lay several layers of thermal protection. The main filler for walls is mineral wool, however, the range of fillers is represented by different types of materials. They differ not only in the degree of thermal protection, but also in the type of installation, care, and can affect the design of the whole house.

What is the best way to insulate a frame wooden house from the inside? This is a difficult question. To answer, it is better to consider all available options:

• Mineral wool and varieties;
• Sandwich panels;
• Styrofoam.

Mineral wool sheets are a dense product that fits inside the frame, between the outer and inner walls. Cotton wool takes the shape of the figure in which it is located, and therefore provides maximum adherence to the walls of the house.

Mineral wool has several varieties: glass wool, basalt stone wool, slag wool, etc. To insulate a frame house, it is better to choose a material with a density of more than 35-50 kg \ m3. So you can avoid its subsidence and the appearance of unnecessary cold bridges.

Sandwich panels combine the qualities of sound insulation and powerful insulation. They are a complex combined insulation system that is folded on the wall like a constructor and immediately provides cross-wall insulation. Unfortunately, the cost of sandwich panels is quite high.

Instead of mineral wool, polyurethane foam is sometimes used - a water-based material that fills the space well, hardens quickly, and provides a high level of protection from the cold. It is not too difficult to work with polyurethane foam - in its qualities it is similar to mounting foam, and therefore its application to walls, trimming, etc. will not be a problem.

The most common type of external insulation is foam. Thick sheets of dense material can protect the house from the wind and keep up to 5 ° heat that can escape through the walls. Styrofoam is attached to the outer wall using building glue, fungal nails, putty mesh. Sheathing the outer wall of the house with foam guarantees the so-called. cross-insulation of the house, where cold bridges (board, timber) are covered with a layer of insulation.

Another task of the foam is to protect the frame from the harmful effects of the environment. Excessive moisture, damage to the skin, bacteria can greatly harm the house. Frame repair is a very expensive pleasure. Styrofoam will protect the frame from most adverse factors. In addition, if the outer skin is damaged, the damaged slab is very easy to repair or replace.

Warming the house from the inside: useful or harmful?

Any type of finishing work significantly reduces the overall quadrature of the room. In addition, with the outer layer of foam plastic already installed, the overall performance of the wall will noticeably drop.

How to properly and cheaply insulate a frame house from the inside? This question must be answered before the start of construction - at the stage of project development. An experienced architect will suggest several solutions to this problem, including styrofoam or sandwich paneling on the inside. The designer may resist this, because a thick layer will take up a lot of interior space. Masters also have the right to vote - the installation of insulation must be done in a short time around the entire perimeter of the walls. Because of this, the choice of types and types of insulation is noticeably reduced.

Mineral wool has a heterogeneous composition - the fibers in it are arranged randomly. It retains heat well, however, for efficient operation, cotton wool must warm up well. Combination: heated room - min. cotton wool - foam plastic, in practice works much better than the combination: room - foam plastic - mineral wool.

For the effective operation of the insulation, it is necessary to correctly alternate different types of thermal insulation. A good option would be a scheme:

Room - double layer min. cotton wool - 5mm foam layer.

Such a plan suggests the installation of an efficient combined system. Cross-insulation of a wooden frame house from the inside allows you to remove 95% of all cold bridges and reduce heat loss through the walls to a minimum.

Styrofoam insulation from the inside is a dubious enterprise. Thus, the wool is protected from the heat source and cannot warm up well. The option is only suitable for buildings located in warm latitudes, or residential premises in which they live in the summer.

The installation process of cross-insulation

Contrary to popular belief, cross-insulation can be created with only one type of material. For a frame house, the standard wall thickness is 150 mm of mineral insulation - glass wool, slag wool, rock wool (basalt). A frame with a board width of 150mm is built under the filler.

Another 50mm of additional insulation is added to the wall thickness. An additional frame is built under it from the outside or inside. As a rule, this is a horizontal board 50 mm wide (according to the thickness of the filler).

The laying of the outer layer of insulation occurs first of all, the filling of the wall occurs "from the street".

Work execution algorithm:

1. The construction of the frame, partitions;
2. Completion of an additional frame for the outer wall;
3. Filling with 50mm sheets of the outer frame;
4. Installation of VVZ membrane on an external wall (industrial stapler);
5. Laying the inner layer of insulation;
6. Installation of external and internal finishes - planks, wooden lining, corrugated board, etc.

This plan can be expanded at the request of the customer or the advice of the foreman. For regions with a cold climate, the thickness of the walls can be increased, a more complex system of moisture and wind protection can be chosen, and an additional source of heating for the house can be installed.

Insulation of a frame wooden house inside involves the placement of thick sheets of thermal insulation over the entire area of ​​\u200b\u200bthe outer walls. In this case, a flat vapor barrier film is stretched over the mineral wool, which is designed to protect the insulation from moisture. An even layer of foam plastic 3-10 cm is glued onto the prepared wall. After the surface is sewn up with a putty mesh, it is leveled with a thick putty for the walls. After that, the wall can be painted, sewn up with drywall, glued wallpaper, etc.

Features of mounting insulation on the frame

Visually, mineral wool does not seem to be pressed against the walls of the frame. Many people think that the insulation should be attached at least with glue, in order to avoid “falling out” of the frame cells.

Properly executed wall decoration is used to hold cotton wool. Both outside and inside, mineral wool must be covered with a layer of waterproofing, the wall must be finished with a special finish - clapboard, drywall sheets, corrugated board, etc.

For the outer wall of the wall, it is better to finish the finish with a layer of thick moisture-windproof membrane. A thick, durable film will protect the filler from moisture ingress from the outside, the formation of steam, and the “falling out” of sheets from an unfinished wall.

Further sheathing: a mesh of thin wooden planks and a thick layer of boards / external lining / corrugated boards / an additional layer of insulation (polystyrene), less often - decorative stone, brick, etc.

The interior wall decoration involves several layers of wall protection from the microclimate of the room: a waterproofing layer (film), heat reflector (foil insulation in rolls), wall decoration.

In terms of wall decoration, it is best to choose a durable material that repels moisture well. Drywall sheets, PVC, MDF, wood paneling, soundproofing + special drywall can be installed as the first and only finishing layer between the filler and the room's interior.

How to insulate an already erected frame house from the inside? For this it is better to use:

1. Thin foam plastic (will remove cold bridges, but allow mineral wool to warm up);
2. Sandwich panels (expensive but effective heating method);
3. Construction of an additional frame for mineral wool.

Any of these options involves a major overhaul of the premises - the outer finish must be removed, the installation takes place close to the inner layer of the filler.

1. When building a large house, it is worth stopping at one type of wall insulation. The use of high-density mineral wool on a combined frame (cross-laying) will allow the house to be well insulated. In addition, you can significantly save on the cost of materials;
2. Using one type of insulation will speed up the construction of the house. Combining different types without following the technique for each can reduce the performance of the house;
3. The placement of the filler should occur gradually, without haste. Attaching cotton to paper clips or glue is of no practical use;
4. Properly made cells in the frame (1-2 cm less than the dimensions of the mineral wool sheet) will allow you to create a really warm wall;
5. Work with any type of filler should be done in overalls. This is especially true of glass wool - the ingress of dust into the eyes and respiratory organs is fraught with serious consequences;
6. When installing polystyrene foam on the outer walls of a frame house, it is necessary to load the supports minimally. In addition, when drilling holes for hats, it is worth remembering the features of the tree. In addition, it is necessary to have at hand the exact scheme of the house: the placement of beams and crossbars in order to avoid fixing the foam "on cotton wool".

Common questions and answers

Q: Are there ready-made projects of houses that take into account the parameters of interior or exterior finishing with thermal insulation?

A: Yes, they are present in abundance on our website in the appropriate section. If it was not possible to find a suitable option, adding additional characteristics to the scheme of an already finished project is much easier and cheaper than developing it from scratch.

Q: What type of insulation is better for a beginner to stay on?

A: If the construction of a small building is underway, the most profitable option for the builder - the amateur will be the cross-laying of mineral wool.

Internal frame: 150 mm wide (for warm latitudes, 120 mm is possible).

External frame (or internal) - 50 mm.

Laying layers: perpendicular.

Q: How long does it take to install insulation for a house?

A: It will take about 12-20 hours for a team of 3-5 builders to install insulation in a one-story house.

Speed ​​plays an important role here: weather changes, rain can ruin the insulation and cause financial damage to the owner of the house.

Insulation of a frame house is the most important stage in the construction of a frame house. Given the fact that the frame house is energy efficient, then the choice of the type of insulation should be taken responsibly.

The choice of heaters is quite wide. Frame houses are insulated with foam, mineral wool, ecowool, polyurethane foam, extruded polystyrene foam. Consider each heater separately.

Overview of insulation materials

One of the cheapest insulation is foam. It is lightweight and easy to install. And, of course, it has a low cost. Styrofoam does not absorb moisture. The advantages of polystyrene, perhaps, end there.

Styrofoam is a combustible material, emitting toxic smoke when burned. In work, although the foam is convenient, it is fragile in structure, so you need to handle it carefully. And when buying foam, you need to make sure that there are no cracks on it.

Mineral wool for warming a frame house

Mineral wool, produced in the form of slabs or rolls, has been very popular lately. It should be noted that basalt wool in slabs is in great demand than in rolls.

Mineral wool has good thermal insulation properties. I don't get angry. But cotton wool contains formaldehyde, which is harmful to human health. Mineral wool fibers, like fiberglass, are carcinogenic.

For this reason, when insulating internal walls with this insulation, it is necessary to use vapor barrier membranes (in addition to the main purpose), so that small grains of mineral wool do not scatter around the room.

When laying mineral wool, it is imperative to use additional products to protect the face and other exposed parts of the body. On top of mineral wool, you can attach not only a vapor barrier film, but simple polyethylene. The seams are sealed with tape.

A significant disadvantage of cotton wool insulation is the fear of moisture. When the insulation is moistened by 2-3%, its heat-insulating properties decrease by 50%. Therefore, it is essential to use a vapor barrier. As a rule, after 25-30 years, mineral wool needs to be replaced.

Styrofoam for home insulation

Extruded polystyrene foam is superior to mineral wool in terms of thermal insulation, and also has a high water repellency, and lower weight. combustible Compared to Styrofoam, Styrofoam is more durable and resistant to chemicals. It does not need to be replaced during operation.

Polyurethane foam is a modern insulation that has appeared relatively recently. Possesses high heat-insulating characteristics. Not hot. It does not contain substances harmful to humans. When spraying with polyurethane foam, the thickness of the sprayed layer can be varied.

Ecowool

Ecowool is a combination of excellent thermal insulation properties and safety. Ecowool consists of 81 cellulose, 12% antiseptic (boric acid) and 7% flame retardant (borax). The raw material for the production of ecowool is waste paper, which is a product of wood processing. Therefore, ecowool is environmentally friendly and does not contain harmful and hazardous substances.

It is not afraid of moisture, does not rot, prevents the spread of fire, the development of fungus, has excellent soundproofing performance. If we talk about the quality of insulation, then only blowing ecowool and spraying with polyurethane foam can create a seamless layer of insulation that will not have voids, cracks, "cold bridges", which cannot be said about plate types of insulation.

Ecowool surpasses mineral wool in its properties and is very similar to polyurethane foam, but at the same time it is cheaper than mineral wool and much cheaper than polyurethane foam. In comparison with polystyrene foam and expanded polystyrene, ecowool also wins in all positions.

Of course, it will not work to lay (fluff) ecowool without equipment with your own hands, and you will have to turn to the installation team for help.

But on the other hand, ecowool insulation will be performed efficiently and reliably. The cost of these services is low, while saving time. In a few hours, you can blow out a large volume.

If we talk about heat-insulating properties, then the most effective heaters will be ecowool and polyurethane foam, followed by polystyrene foam, mineral wool and polystyrene foam.

Photo of frame house insulation

To achieve a comfortable stay in the house during the 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 instructions for each type of structure are 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 with the temperature regime of the dwelling and a decrease in 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 of this heater. 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 attic roofing, 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 own hands, you can protect the following elements of the building from the cold:

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 thermal insulation between the racks, as this will ensure the competent work of the material. Warming a wooden house with mineral wool from the inside of the wall will greatly simplify the work and allow you to hold events in all weather conditions.

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

• the 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

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 the hinged facade, the order of the layers 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 laid between the supporting structures of the floor. 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, it is better to take the step of the wooden floor beams so that 580 mm remain clean between them. This will provide maximum convenience for working with 600 mm wide plates 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.

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.
