Insulation of a frame house is the most important stage in the construction of a frame house. Considering the fact that a frame house is energy efficient, the choice of insulation type should be taken responsibly.
The choice of insulation materials is quite wide. Frame houses are insulated using polystyrene foam, mineral wool, ecowool, polyurethane foam, extruded polystyrene foam. Let's consider each insulation separately.
Review of insulation materials
One of the cheapest insulation materials is polystyrene foam. It is lightweight and easy to install. And, of course, it is low cost. Polystyrene foam does not absorb moisture. The advantages of polystyrene foam, perhaps, end there.
Polystyrene foam is a flammable material, releasing toxic smoke when burned. Although foam plastic is convenient to work with, its structure is fragile, so it must be handled with care. And when buying polystyrene, you need to make sure that there are no cracks in it.
Mineral wool for insulating a frame house
Mineral wool, produced in the form of slabs or rolls, has been very popular recently. It is worth noting that basalt wool in slabs is in greater demand than in rolls.
Mineral wool has good thermal insulation properties. Not flammable. But cotton wool contains formaldehyde, which is harmful to human health. Mineral wool fibers, like fiberglass, are carcinogenic.
For this reason, when insulating interior 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 throughout the room.
When laying mineral wool, it is imperative to use additional funds 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 also simple polyethylene. The seams are taped.
A significant disadvantage of cotton insulation is the fear of moisture. When the insulation is moistened by 2-3%, its thermal insulation properties are reduced by 50%. Therefore, it is imperative to use a vapor barrier. As a rule, after 25-30 years, mineral wool needs to be replaced.
Foam plastic for home insulation
Extruded polystyrene foam is superior to mineral wool in thermal insulation properties, and also has high water repellency and lower weight. Flammable Compared to polystyrene foam, expanded polystyrene is more durable and resistant to chemicals. It does not need to be replaced during operation.
Polyurethane foam is modern insulation, which appeared relatively recently. Has high thermal insulation characteristics. Not flammable. It does not contain substances harmful to humans. When spraying with polyurethane foam, you can vary the thickness of the sprayed layer.
Ecowool
Ecowool is a combination of beautiful thermal insulation properties and safety. Ecowool consists of 81 cellulose, 12% antiseptic (boric acid) and 7% fire 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 dangerous substances.
It is not afraid of moisture, does not rot, prevents the spread of fire and the development of fungus, and has excellent sound insulation properties. If we talk about the quality of insulation, then only blowing in ecowool and spraying with polyurethane foam can create a seamless layer of insulation that will not have voids, cracks, or “cold bridges,” which cannot be said about slab types insulation materials.
Ecowool is superior to mineral wool in its properties and is very similar to polyurethane foam, but 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 respects.
Of course, you won’t be able to install (fluff) ecowool with your own hands in a high-quality manner without equipment, and you will have to turn to the installation team for help.
But insulation with ecowool will be done efficiently and reliably. The cost of these services is low, and time is saved. You can blow out a large volume in a few hours.
If we talk about heat-insulating properties, then the most effective insulation materials There will be ecowool and polyurethane foam, after them come polystyrene foam, mineral wool and polystyrene foam.
Photo of insulation of a frame house
The technology for building a frame house, which came to us from overseas, is gradually replacing all other types of buildings. Many advantages and a minimum of disadvantages brought it to the peak of popularity. More and more of our compatriots, faced with choosing the type of construction of their new home or cottage, give preference to it. Unfortunately, erecting a box, covering the façade with facing materials, and finishing the interior of the room does not new house suitable for living, because the climate in our country is very harsh. And in order for the home to be complete, and for its inhabitants to not have the desire to quickly move somewhere else, it must be insulated. In this regard, a logical question arises - how to insulate a frame house from the outside so that it becomes cozy and serves its owners faithfully for many years?
It is possible not to insulate a frame house, but in this case the owner must be prepared for exorbitant sums that will need to be paid for electricity and heating. And, of course, you shouldn’t expect the home to be quite cozy and comfortable.
External insulation of the house
There are several ways to install a thermal insulation layer when constructing a frame building. In some cases, insulation is filled into the gaps between the components of a frame building during the construction of walls. This method of arranging thermal insulation allows you to save usable space both inside and outside the building. In this case, the insulation is laid in a checkerboard pattern between the frame posts. The checkerboard pattern is needed to prevent the appearance of cold bridges in the heat-insulating layer.
In the event that it was not possible to carry out insulation at the construction stage, or the issue of thermal insulation arose after completion construction work, That additional insulation performed outside a newly constructed building by installing necessary materials on the surface of the facade.
It is best to choose material for insulation in slabs 5 cm thick. The total thickness of the layer, depending on the climate, should be from 10 to 25 cm. To protect the room from moisture and wind, a vapor barrier film is used, and a superdiffusion membrane is used to prevent moisture from appearing in the insulation.
The vapor barrier film must be glued to the walls with an overlap of 15-20 cm. The seams are taped with moisture-resistant tape.
Choice of insulation
If the question of how to insulate a building had arisen in the last century, then there would have been no problems with the choice of material. At that time everything was done very simply. For this they used clay, straw or sawdust. They were used to make mixtures that were used to treat the walls. Now this type of insulation is not relevant and from the outside it looks, to put it mildly, comical.
Today the market is crowded various materials, and search suitable insulation may confuse an inexperienced and uninformed person in this matter. Therefore, it is important to know the characteristics, advantages and disadvantages of one or another material in order to find the most suitable one.
The following insulation materials are popular:
- mineral and ecowool;
- Styrofoam;
- polyurethane foam.
Insulation made of mineral wool and ecowool
Mineral wool is very often chosen for insulation. The material performs well in conditions high temperatures and combustion, it is lightweight and vapor permeable. Installation does not require much effort or special skills.
Quite often ecowool is used for insulation. You can buy it in briquettes. One weighs 15 kg. Before use, it is loosened, and then poured between the frame posts and compacted.
Over time, shrinkage of the material may occur, leading to heat loss. This is a disadvantage of ecowool.
Using foam plastic for insulation
The main advantage of polystyrene foam is its little weight, making it very easy to work with. The sheets are mounted without much difficulty, and in the future they do not affect the environment or people.
A huge advantage of polystyrene foam is that it does not rot or be affected by bacteria or fungus. Once installed on the wall surface, there will be no need to cover it with film.
Also among the advantages of this material is its low price, which allows you to save a lot on insulating a frame house.
On the other side of the scale is such a significant drawback as susceptibility to combustion, during which many harmful chemicals are released into the environment.
You can replace polystyrene foam with a flame retardant variety called extruded polystyrene foam.
Application of polyurethane foam
Insulation with polyurethane foam is performed by spraying onto the surface of the walls of a frame building. This option provides the highest quality thermal insulation among all others.
The application of a layer of this insulation is carried out using special equipment. All the necessary components are mixed inside the device, after which the mixture is sprayed onto the surface of the walls of the house. There, the polyurethane foam foams and turns into a solid state, forming a strong crust.
useful in work
The advantage of this insulation is the ability to apply it to almost any surface.
The disadvantage is that polyurethane foam is easily exposed to ultraviolet radiation, which means that if it comes into contact with direct sun rays he will lose his performance characteristics. Therefore, to prevent this from happening and to prevent the service life of the insulation from decreasing, you should not delay covering the facade facing material.
Preparing walls for insulation
Proper preparation must be done before any construction process. The insulation of a frame house is no exception.
If the building has already been in operation, then it is necessary to check the condition of all walls with outside. All unnecessary elements must be removed from the facade, such as nails, screws, other construction elements, damage, bulges, etc. All such defects must be removed from the facade so that it is as clean and smooth as possible. All cracks that can be seen from the outside of the walls must be sealed. polyurethane foam.
You also need to carefully inspect the surface for damp areas. If there are any, they need to be dried using a hair dryer, and measures must be taken to find and eliminate problems that led to such consequences.
For a frame house under construction, preparatory work also needs to be carried out. The frame of the walls is covered with chipboards from the inside. Then the process of removing defects takes place, as well as sealing the cracks with polyurethane foam. On inner surface A vapor barrier film is applied to the walls to protect the insulation from air vapors emanating from inside the room. It then closes when interior decoration clapboard or drywall.
Facade insulation
Next, on the outside, on the surface of the walls, insulation is laid in layers. How many layers will be installed depends on the climate of the region. During installation of the material, each subsequent layer must overlap the joining seams of the previous one.
After installation is completed, the wall is covered with a windproof membrane, which is secured using a construction stapler. Then a sheathing is constructed, which serves to provide a ventilation opening between the membrane and the facing material. The gap should be approximately 20-40 mm.
Attached to the sheathing particle boards, after which you can cladding the facade. For this purpose, siding, lining, etc. are used.
If this insulation turns out to be insufficient, then another one can be installed outside, applying an additional layer to the surface of the facade.
The sound insulation, comfort and durability of the entire structure depend on how correctly and with what kind of thermal insulation material the frame house is insulated. High-quality insulation will retain heat inside the room for a long time and save the amount of energy required for heating it. That is why it is extremely important to know how to insulate a frame house for winter accommodation inside and out.
Insulation from outside
One of the best options thermal insulation of a frame building is cross insulation.
Note! Insulation mats are always laid with the seams staggered so that they do not coincide. This will help avoid the appearance of blown cracks.
Cross insulation allows you to block all cold bridges in the frame, which are wooden elements designs. To do this with outside at home, besides standard insulation layer of 15 cm, it is necessary to lay a layer of thermal insulation 5 cm thick.
To do this, bars measuring 50x50 mm are attached to the outside of the frame in a horizontal position. They are installed alternately, from bottom to top, at a distance of 59 cm from each other (this distance depends on the width of the insulation used; 1 cm less than the insulation). After that, 5 cm thick thermal insulation is placed between them in the spacer. Once all the insulation is installed, it is covered with a moisture-proof membrane. It will not only protect it from moisture and wind, but will also hold the slabs in the frame. The insulation inside the house will also not be able to fall out, since it is laid across the frame.
Scheme of a cross-insulation pie for a frame house Sheets of windproof film are laid overlapping, at least 15 cm on top of each other. Secure the membrane to the bars with a construction stapler. Another sheathing is installed on top of the film using bars measuring 5x5 cm - for installing the finishing coating and to create a ventilation gap.
Insulation from the inside
After the installation of insulation on the outside of the frame house is completed, they proceed to laying the first layer of thermal insulation 5 cm thick from the inside of the building. It is mounted in such a way that the slabs are flush with all the jibs. The next layer is thermal insulation with a thickness of 10 cm. It completely fills the entire frame between the racks.
After this, a high-quality vapor barrier membrane is attached from the inside; it will limit the penetration of steam into the insulation. Place the smooth side against the thermal insulation and the rough side inside the room. The sheets are spread overlapping, and the abutments are glued double-sided tape. It is mounted on top of it with lathing beams 5x5 cm for fastening the finishing coating.
Note! The insulation cannot be compacted or pushed by force, since the thermal conductivity of mineral wool depends on the number of air voids in its structure.
Thermal insulation should be as free as possible between the frame posts, filling it completely, without gaps.
Pie diagram internal insulation frame house walls Insulation is also installed in the interior partitions, but not for the purpose of insulation, but as sound insulation. Mineral wool thermal insulation, especially basalt, is a good soundproofing material. The slabs are laid in a layer of 100 mm (2 x 50 mm with joints spaced). For interior partitions no installation required vapor barrier membrane, since the room temperature on both sides is approximately the same. Therefore, heat does not tend to escape and does not saturate the insulation with wet steam.
Note! Glassine is used instead of vapor barrier for interior partitions. It prevents mineral wool dust from leaking into the room. Cover it with insulation on both sides.
Insulation basement floor frame house is practically no different from thermal insulation of walls. Essentially this is the same wall, but in a horizontal position. From below, the floor is covered with a high-quality windproof membrane with an overlap on strapping beam from all sides. The film is secured to the subfloor so that the insulation laid in the frame does not squeeze out or tear it. Next it is laid in 2 or 3 layers thermal insulation material with seam spacing.
The basement floor must be insulated with a layer of 200 mm. IN interfloor ceilings a layer 15 cm thick is laid for sound insulation, and the attic is thermally insulated with a layer of 250 mm.
Scheme of insulation of the basement floor of a frame house How not to damage the vapor barrier and other nuances
According to the standard scheme, to insulate a frame house, the installation of 150 mm of thermal insulation material is required.
But there are several nuances that need to be taken into account:
- The frame of the house itself allows heat to pass through, as the thermal conductivity coefficient of wood is significantly higher than that of any insulation.
- After installing thermal insulation based on mineral wool, for example, basalt, on the outside of the building, it is necessary to cover it with a windproof membrane, and cover it from the inside with a vapor barrier film.
Since power networks pass inside the frame, the outputs are passed through a vapor barrier. As a result, the film becomes leaky, and some of the heat passes through the holes to the outside, letting cold into the house. Even after gluing with special tape, the tightness of the structure cannot be guaranteed.
To avoid such a problem, you should make additional sheathing along the inside of the frame and fill it with insulation 5 cm thick. It is extremely important to arrange it as evenly as possible, using building level or laser level. Since in the future it will be attached to sheet material, for example, plasterboard, for finishing with a finishing coat.
The bottom beam of the sheathing should retreat from the monolithic part of the foundation by approximately 15-17 cm. This is necessary so that when pouring the floor screed, it does not interfere with the sheathing and insulation.
Before installing the frame, you must immediately take into account the dimensions of the insulation boards so that no additional fastenings are required. But at the same time, the center-to-center distance between the horizontal slats must be at least 120 cm (according to the size of the drywall sheet).
For high-quality finishing frame house requires the installation of two layers of drywall. The first is mounted in a horizontal position, and the second in a vertical position.
Thanks to this method, the sockets will be installed up to the vapor barrier layer, that is, its tightness will not be compromised. In addition to all this, an additional sheathing with insulation 5 cm thick will completely block all the cold bridges and cover the entire frame of the house, increasing the thermal insulation of the room.
When choosing thermal insulation, hydro and vapor barrier building materials, you should give preference to manufacturers of well-known brands, whose products have been tested by time, and also have quality and safety certificates. Cheap insulation materials can quickly lose their heat-saving characteristics or be unsafe for indoor use.
Insulating the walls of a frame house - important stage construction, which should not be neglected.
It is worth approaching this process seriously and responsibly, because frame houses are in no way inferior to concrete or brick ones in reliability and durability, and in most cases even benefit.
If you want your home to be a real holiday: warm and comfortable in winter, fresh and cozy in summer, then everything is in your hands.
Let's figure out how to properly insulate the walls of a frame house with your own hands.
Information about the most popular insulation materials
Today, a considerable number of insulation materials are known that are used in construction. frame houses. Each has characteristic properties, its own pros and cons.
When choosing insulation, you should pay attention to the following parameters:
- low level of thermal conductivity;
- fire resistance;
- health safety;
- ease of installation;
- lack of tendency to deformation;
- long service life;
- value for money.
Today, in the process of building a home, the most popular materials for wall insulation are polystyrene foam and mineral and basalt wool.
The article is devoted to the features of these types of insulation, their advantages, disadvantages and nuances of the installation process.
Mineral wool is a popular quality insulation material. Mats or rolls are used for insulation.
They are easy to install, lightweight, durable, have excellent noise insulation and low thermal conductivity.
The disadvantages of insulating material include not being environmentally friendly (containing a small dose of substances harmful to health) and the inability to withstand the action of moisture (leading to loss of thermal insulation properties).
Mineral wool is mainly used during external insulation. One type of mineral wool is basalt wool.
The material has a number of positive properties:
- low thermal conductivity;
- health safety;
- resistance to various environmental influences;
- fire resistance;
- strength;
- long service life.
The disadvantage of insulation with basalt wool is the cost of the material. But a large number of the advantages of insulation cover this minus.
Recently, polystyrene foam has rapidly become the leader among frame house insulation materials.
First of all, thanks to its low price. In addition, the material is convenient to use, lightweight, and harmless to health.
But at the same time, polystyrene foam has significant disadvantages:
- is highly flammable and, when ignited, releases toxic substances;
- very fragile, can be easily damaged during operation;
- The material can be significantly damaged by rodents.
Although many experts claim that rats and mice do not eat polystyrene foam, but establish their homes there.
They say that modern polystyrene foam is made with the addition of fire-retardant additives.
It's time to familiarize yourself with the technology of wall insulation using each of the materials mentioned.
Insulating the walls of a frame house with cotton wool
Insulating the walls of a frame house mineral wool– the process is labor-intensive, but effective.
The main thing is that the walls are maintained correctly. First, let's consider insulating the external walls of a frame house with our own hands.
On initial stage work, the outside frame of the wall is sheathed with slabs (chipboard) so that there are gaps between them, which can be foamed at the end of the work.
Then insulation is laid layer by layer between the frame posts.
To prevent the formation of void bridges and cold bridges, you should take mineral wool with good density and lay each layer slightly offset.
The amount of insulation varies depending on climate zone location of the home.
The next step is to fill all the voids with foam. After this, you need to tighten the insulation vapor barrier film, and put a sheathing on it.
Now let's talk about insulating interior walls with our own hands.
Often this procedure carried out to soundproof walls. It is advisable to use a special sound-absorbing material, but mineral wool will also work.
It is worth noting that protective membranes are not required for this process. The remaining stages of insulation of external and internal walls are the same.
Anyone who has at least the slightest construction skills can insulate the walls of a frame house with basalt wool. But at the same time, the process requires serious responsibility and concentration.
Before insulating the external walls of a frame house, cracks should be repaired. For this purpose, installation foam, tow, etc. are useful.
It is necessary to lay a vapor barrier layer (foil, polyethylene film, parchment paper) with ventilation. The film will protect the insulation from moisture, ventilation will facilitate the passage of air.
The insulation process consists of the following stages:
- Mounting and fastening of a metal cornice to facilitate the process of laying insulating material and as protection against mice and rats;
- Gluing a basalt slab to the wall. To begin, fill out thermal insulation boards large wall sections, then smaller sections;
- Leveling the wall surface.
As for the insulation of internal walls, the material here also performs a soundproofing function. The technology is identical to the scheme for insulating external walls.
So, the processes of insulating walls with mineral and basalt wool with your own hands are similar.
They require certain construction knowledge and skills, diligence and faith in one’s potential. It is necessary to take into account all the subtleties of insulation technology.
Working with foam plastic
With positive and negative sides You are already familiar with polystyrene foam as insulation.
Now let's look at how to insulate the external walls of a frame house using polystyrene foam. In the process of insulating walls with your own hands, the temperature must be maintained above zero.
At the initial stage, you should prepare the frame (get rid of unnecessary objects; treat the surface with antiseptics, in order to protect the home from fire, level it (air should not get into the cracks), if possible, fill the gaps with frost-resistant foam (for installation); treat the surface with primer and allow to dry).
The next step is to apply a waterproofing layer (foil, polyethylene film, parchment paper), which acts as protection for the walls from wind and moisture, applied from the outside.
There is an opinion that polystyrene foam does not absorb moisture at all, and a waterproofing layer is not needed.
But when low temperatures Humidity can destroy insulation. So laying this layer is necessary step insulation. Protective film glued with tape or special tape.
For high-quality insulation For a frame house, experts recommend laying three layers of insulation on top of each other, not forgetting to treat the joints with frost-resistant foam.
Be sure to position the slabs correctly so that they do not deform under the influence of temperatures, negatively affecting the cladding.
The inside walls are wrapped with a vapor barrier film to prevent condensation from forming on the insulation.
Penofol and various vapor barrier membranes are used as protection.
External cladding can be made over a waterproofing layer. Here you can do without ventilation.
Insulating the walls of a frame house with foam plastic inside the building is similar to insulating external walls.
So which insulation should you choose for your frame home? Let's summarize.
A frame house is practical, durable and very a budget option construction. It has multiple advantages, especially in the area of ease of design and installation.
Insulation remains an unchanged nuance for a frame house; despite the basic insulation installed in the niches, it is necessary to additionally ensure heat retention.
The material of a frame house is wood or metal, more often they complement each other. Therefore, additional insulation is used either outside or inside.
Insulating walls in a frame house has long ceased to be a luxury; now it is more of a necessity. Since lately frame structures are becoming increasingly common in cold regions of the country, it is worth thinking about warmth and comfort in the house.
Each insulation option deserves its right to exist, since in some situations it shows more good results. The advantages and disadvantages of each method should be analyzed point by point.
has a higher heat retention coefficient, thus energy costs will be minimal.
This is due to the fact that there is no need to warm up the walls; most of the air is retained directly in the room. The situation is twofold, since walls can also collapse due to a shift in the dew point. So the moisture from the cold air will be transformed into droplets almost in the room itself.
Comparison of insulation methods
Also internal option insulation is easier to install; you can reach the wall using a simple stepladder.
In contrast to this advantage, there is a nuance - this is a decrease in the variety of wall decor, that is, the insulation is less durable and fastening some structures can be difficult. It's logical that the construction of an additional layer on the walls leads to an overall reduction in the area of the house.
When using the method of internal wall insulation, be sure to pay attention to the environmental friendliness of the material.
- this is more standard and safe way heat preservation. This type insulation has the following advantages:
- The walls are protected from destruction and are less susceptible to weather conditions;
- Does not take up space in the room;
- Lower requirements for the environmental component of insulation;
List the main types of insulation and their brief description
Insulation materials are divided according to their properties and method of application, but today the variety of materials is so large that it is very difficult to describe all the options, so only the most popular methods will be discussed.
Comparison of thermal insulation
Stone wool
Stone wool is a material that is used everywhere, it is preferred by many development companies. The popularity of cotton wool is based on easy installation, since no special skills are required and you can get by with improvised tools.
NOTE!
Used in frame houses, which are built with one’s own hands, that is, not of a factory design. Thermal insulation is used to fill the openings between the beams of the frames.
Due to its distribution, cotton wool can be found in almost every major hardware store, and transportation is possible even in your own car. The main requirement for installing wool is its installation density - there should be no gaps.
Stone wool
Styrofoam
- This is a cheaper and moisture-resistant insulation, but it is also quite fragile. Installation of foam plastic is somewhat more difficult and requires some experience in this area. Since the material does not absorb moisture, there is no need for moisture/vapor protective membranes, which reduces the cost of the project.
The performance characteristics of polystyrene foam somewhat repel many people, which is why serious disputes flare up around the material. As negative aspects, they note that the material is not at all environmentally friendly and people complain about a deterioration in their health after insulation.
Styrofoam
Mineral wool
Often used in construction due to its high thermal/sound insulating properties and minerals are increasingly gaining popularity in private construction.
Cotton wool has the form of fibers that are several times smaller than hair, and all this is in compressed form. The fiber length is 10-15cm.
Due to the presence of a huge number of air cavities, the material retains heat well, and along with it, sound. Installation of wool is as simple as possible due to the flexibility and elasticity of the blocks, and there is no tendency to deform. There is no risk of fire.
Mineral wool
There are many other types of insulation, such as:
Frame wall insulation pie - what elements does it consist of?
There are several main options for building a frame house, the first is a factory one, when ready-made blocks are initially purchased, it is called frame-panel. Another method is to arrange and assemble the panels on site, essentially by hand.
Both options must contain several important layers, each of which has its own specific function. In fact, there are only 5 main layers:
- So, naturally, he goes first façade cladding, this also includes external insulation, so the function is an attractive design and protection from temperature changes;
- Further windproof membrane protects the house from drafts, removes moisture and thereby retains heat;
- The frame itself always contains some kind of insulation;
- A vapor barrier layer protects the insulation from the penetration of water vapor, which in turn ensures the durability of the building;
- Internal lining. There are no special standards here; you can use internal insulation, varied decor and everything that seems appropriate to the owner.
Insulation pie
Layers of vapor barrier and wind protection must be secured using lathing. It is a mesh, usually made of wooden blocks, which fixes the necessary films and internal insulation, preventing deformation of the structure.
Sealing cracks and preparing sheathing
Lathing is vital in insulating a frame house. The reason is 
that it is simply impossible to attach to mineral wool or any other filler, since they are not able to withstand loads.
Further work requires the presence of sheathing; the material can be either a regular beam or a profile.
The sheathing itself additionally serves to seal the inner layer of insulation and provide additional ventilation.
- Before preparing the sheathing All cracks must be sealed first, which can be formed due to a loose fit of the insulation.
- It is necessary to fill the niches in the frame so that a slight pressure of the insulation is formed on the supports. This is done so that if the beams dry out, gaps do not form due to the filler, otherwise big losses heat guaranteed.
- Various gaps that cannot be closed using the material simply blown with foam.
- The sheathing itself is done as simply as possible. To install the sheathing, a board measuring 20x90mm is used. The sheathing is attached to wooden planks, which secure the insulation. You can fill the timber in absolutely any direction, it depends on the decor you choose.

Proper insulation of the walls of a frame house with mineral wool - in detail and step by step
It is worth noting that mineral wool is very good material for insulation, but it still has several negative parameters, such as highlighting harmful substances, What limits its use indoors.
It is also noted that the material is afraid of moisture and water vapor.
If the mineral wool is saturated by even a few percent, the insulation loses half of its heat-insulating properties.
Now you should highlight several basic steps for insulating walls with your own hands when using mineral wool:
- First, it is necessary to sheathe the inside of the structure with a vapor barrier material;
- Then sew up inner side frame, this is often done using OSB. In this way, niches are created for further sealing;
- Usually niches are made to fit the size of mineral wool, but if necessary you will have to trim the sheet with a simple knife. It is worth considering that you should cut 5 mm more on each side than was measured, this creates additional protection from possible cracks;
- Selecting the number of mineral wool sheets. Each is 5 cm thick, the calculation must be made based on the terrain, in normal cases 2 sheets are enough. Sometimes niches are made in several layers that intersect;
- Now the frame is sheathed on the outside with wind protection;
- The sheathing goes on top of the insulation.

Laying insulation
Insulation of frame walls with polystyrene foam - in detail and step by step
Despite the fact that mineral wool is a good material for insulation, it is worth disassembling internal methods heat preservation. Here the choice of material should be taken seriously, since one of the most important criteria In addition to thermal conductivity, the product becomes environmentally friendly.
The best material for internal insulation, in all respects, is. It has low thermal conductivity, is lightweight, does not allow vapor to pass through and is thin, but alas, it is somewhat more expensive than other materials.
Installation of polystyrene foam is quite simple:
- A layer of wind protection is laid;
- The slats are attached and can be installed in a horizontal or vertical position;
- The interior is filled with extruded polystyrene foam;
- Usually still coming vapor barrier, but with this material there is no need for it, so next comes lathing and drywall or any other finishing material.
Laying polystyrene foam
A few words about waterproofing and vapor barrier
Vapor barrier is a certain film that does not allow moisture to accumulate in the layer with insulation. In this way, the penetration of any vapor from the room into the various layers of insulation and back is blocked. Often used in conjunction with waterproofing.
Vapor barrier
Waterproofing helps to minimize the phenomenon of dew point. Blocks moisture from entering the insulation, usually used on the outside of the wall.

Conclusion
Insulation brings comfort and coziness to the house, blocks the occurrence of harmful, destructive phenomena in the structure and at the same time retains heat.
It’s not for nothing that frame houses are often called thermoses, because if built correctly, the building can retain heat even in the cold season for several days. Also, do not forget about ventilation, since air circulation in the room is minimal.
