Insulation for frame houses comparison. Which insulation is better for a frame house. Polyurethane is a new word in the field of wall insulation

Frame houses have become an excellent innovation in our country - an inexpensive and fast way to build individual buildings.

But, despite the large number of advantages, these buildings have one important drawback: these buildings require additional thermal insulation, since the climatic conditions in Russia are very harsh.

Let's consider which insulation is better for a frame house? How to properly carry out thermal insulation work, and what insulation is best to use.

There are many materials for thermal insulation of houses made using Finnish technology. Each has its own disadvantages and positive aspects, so in order to understand how to choose insulation for a frame house and apply the optimal thermal insulation option, it is worth examining in detail the most popular thermal insulators on the construction market.

Mineral wool for insulating frame structures

How to properly insulate a frame house with mineral wool? This material is often used not only by construction companies, but also by private developers.

This is understandable - the insulation has excellent sound absorption and retains heat excellently. Mineral wool is an environmentally friendly, fire-resistant material. A 5 cm layer of insulation is capable of retaining heat as well as half a meter thick brickwork.

The main nuance when installing basalt insulation is the installation of a vapor barrier to protect the material from moisture. The fact is that when mineral wool gets wet, it loses its thermal insulation properties.

If you decide to use this insulation for insulation, then do not spare money on purchasing vapor barrier material and special membranes.

How to insulate with mineral wool

The insulation of the walls of a frame house is carried out using lathing, the cells of which should be spaced 60 cm apart - this is important, since stone wool is produced in a roll of this size. The insulator must be cut so that the wool fits between the bars with force and does not sag.

The thickness of the material is selected based on weather conditions in the region. If the climate is harsh, then it is better to use layers 20 cm thick; in mild climates, 5–10 cm is enough.

With multi-layer insulation, cold bridges may appear; to eliminate them, 5 cm slabs are laid in two layers, in cells. It is worth understanding that the guide bars must have a cross-section of 10x10. The second two layers of material are laid on top of the frame bars.

Insulating a frame house with mineral wool requires a mandatory vapor barrier, but since the outer wall of the building is already equipped with this material, it can not be used before installing the insulation.

After laying the insulator, care must be taken to protect the mineral wool from condensation fumes. The vapor barrier material is sold in rolls, and it will not be possible to lay it in one sheet, so we purchase construction tape to seal the joints.

Floor insulation in a frame house is done with the same basalt wool. Only in this case, the insulator layer must be at least 20 cm. The work is carried out as when insulating frame walls.

Ecowool insulation

An environmentally friendly and affordable insulation for frame houses, the production of which uses waste from the production of cellulose products: paper, cardboard. Ecowool consists of 80% fiber and 10% antiseptic, which protects against the development of fungal formations and microorganisms. To make the insulation less flammable, 10% special additives were introduced into its composition.

Ecowool - disadvantages

Private developers very rarely use this material to insulate their buildings. Ecowool has a number of features that some builders consider as disadvantages:

Strictly follow the standards for filling surfaces with insulation recommended by the manufacturer, otherwise during the shrinkage process areas without insulation may form.

Positive characteristics of ecowool

Many may think that such a process as insulating a frame house for winter living using ecowool is impractical, since this material has a lot of disadvantages.

But with strict adherence to application processes, the positive characteristics of the material are significantly enhanced:

• Low material consumption makes it cost-effective.
• Ecowool has good noise-absorbing properties.
• The best insulation is made from natural raw materials, which determines its environmental friendliness and safety for people living in the house.
• The composition gains resistance to combustion thanks to additives, and it is worth studying the composition of the product before purchasing. If the composition contains components such as boric acid and ammonium sulfate, then it is better to refuse its use. These components give ecowool an unpleasant and persistent odor, while the fire resistance of the material practically does not decrease. You should only buy a product that contains borax.
• The material is laid without seams, which is a huge advantage, since there are no cold bridges, and the insulation of a wooden house is high-quality and reliable.

But the decisive factor indicating the importance of using cross-insulation of a frame house from the inside with this material is the inexpensive cost in combination with positive characteristics.

Insulation of a frame house with ecowool - technological process

As is already known, there are two ways to insulate a frame house – “wet” and “dry”. You can simply spray the material on the walls by diluting it with water or glue, then you will get a great result. But most private developers follow a simpler path and use the “dry” method of insulation, which we will consider.

So, we insulate the frame house with our own hands using ecowool according to the following algorithm:

• First of all, we will begin to thermally insulate the floor in the house, for this a pressed briquette of material weighing 15 kg needs to be loosened well, for this you can use a regular drill with a special attachment. After these steps, the volume of material will increase three times;
• thermal insulation of the floor of a frame house is quite simple - the material is poured onto the rough covering between the beams with a slight excess, which will be pressed down by the weight of the board for finishing;
• Let's move on to the walls. Before insulation begins, a frame is constructed from bars of the required cross-section. A vapor barrier is attached to the racks, a mandatory element when insulating with ecowool. The frame is sheathed with OSB sheets so that there is a gap on top for filling in insulation. The material will compact under its own weight as it falls asleep, and the top should be well compacted.

When working on thermal insulation of a frame house with ecowool, it is worth stocking up on protective equipment: gloves, goggles and a respirator. You can significantly optimize the process by renting equipment that loosens the material and blows it out in finished form.

Linen based insulation

Linen has excellent heat-retaining parameters; this is achieved thanks to the optimal combination of density and porosity of the material.

Linen insulation is produced in several configurations:

• slabs can be used to insulate a frame house from the inside;
• linen strips of laminated veneer lumber construction;
• oakum is used to caulk the walls made of logs.

Due to its high density, this insulator is used for insulating roofs, floors, partitions and attic floors in which recreation areas are installed.

Thermal insulation made from flax fiber can be considered the most preferable for insulating a house from the inside - it is environmentally friendly, lasts for more than 70 years, does not rot, and mold does not form on it. Unlike ecowool, it is not subject to shrinkage.

Expanded polystyrene or polystyrene foam - which is more practical?

Choosing insulation for a frame house is not an easy task; many nuances need to be taken into account. As for such heat insulators as expanded polystyrene and polystyrene foam, both materials are successfully used to insulate a house from the inside and outside.

Polystyrene foam, of course, is inferior to its counterpart in some positive properties, but it is so cheap that many private developers prefer to use this material for home insulation.

Among the disadvantages are:

• low level of sound insulation;
• when burning, toxins are released;
• the material is susceptible to attacks by rodents.

Thermal insulation of the facade with foam plastic

• Insulating a frame house from the outside begins with preparing the surface, which needs to be leveled, cracks repaired, and primed with deep penetration impregnation.
• After the facade has dried, you need to install direct hangers on it, which will prevent the slabs from moving off the surface; they will be securely fixed.
• Five dots of glue are applied to the foam, the edges are coated around the perimeter.
• The slab with glue is pressed tightly to the surface, working from corner to corner.
• The second row of foam boards is laid in a checkerboard pattern.

The glue composition is prepared in such a way that it can be produced in an hour.

Inconsistencies in the material are adjusted with a heated knife; when gaps form, they are sealed with the following compounds:

• crushed foam is added to the glue;
• fill with penoizol;
• apply polyurethane foam.

For structural strength, the heat insulator should be attached to the surface with plastic dowels, 5 pieces each. on the stove. After this, you can apply any facing material.

Thermal insulation of a frame structure from the inside

The insulation scheme for a frame house from the room side is similar to the previous version. The only difference is in the soil used - you need a composition for interior work with antiseptic properties.

When using an insulating insulator on the inside, simple tile adhesive is used as an adhesive along with dowels.

The installed foam plastic slabs are covered with overlapping reinforcing mesh if the surface is to be puttyed, but plasterboard is often used for wall cladding. This method of thermal insulation is much simpler than insulating a frame house using ecowool.

Penoplex

Don’t know what is the best way to insulate a frame house? Buy penoplex - an analogue of polystyrene foam, only with a denser structure, which is why it costs a little more. It is also worth noting that this material is much more demanding during installation - you need to protect it from moisture and sunlight.

In custody

We built a frame house - insulation can be done either independently or with the help of a team of specialists. Is the building located in a harsh climate? Apply cross insulation, and we described in detail above how to choose an insulator and how to properly insulate a frame house.

Frame houses are being built very, very actively. But even such reliable and high-quality structures in the Russian climate cannot do without insulation. And this means that a quiet life in the house depends on choosing the right option and on competent work.

Why is it necessary?

Panel buildings are very popular among summer residents: they are attracted by the opportunity, having started work in late autumn, to have a full-fledged house by the beginning of the season. In this case, such buildings:

• environmentally friendly;
• are inexpensive;
• serve for many decades.

But all these advantages are realized only if the insulation of the frame house is done properly.

Otherwise, it will be quite difficult to call it comfortable. It is worth immediately distinguishing between two types of buildings.

• Buildings for permanent use by default must have solid thermal protection.
• If you plan to be there only from late spring to late autumn, thermal insulation should be minimal - strictly to maintain the stability of the structure itself.

The “frame”, intended for the summer period, has a wall thickness of no more than 70 mm. During the cold season, the required figure is at least twice as high. If you limit yourself to a thinner layer of material, the heat leakage will be disproportionately large, and you will either have to freeze or lose a lot of money on heating.

Important: for winter living you will have to insulate not the entire volume of the frame, but only its individual parts, first of all:

• stingrays;
• basements;
• attic planes;
• basement structures.

It will not be possible to get by with a heated floor alone, even if its power is excessive. Through the basements, external walls and other parts of the panel house structure, heat will flow away just as vigorously. Considering the variety of conditions where insulation will be installed, it is impossible to give a universal answer about the best option. Basement walls are equipped with some types of thermal protection, load-bearing walls with others, and cold attic ceilings with others. But in any case, the choice of suitable insulation formats always comes first.

Types of thermal insulation

Cross (additional) insulation of frame structures is carried out, as its name suggests, by adding an auxiliary volume of insulation to one layer. This solution allows you to reliably close existing cold bridges. Most builders prefer the external location of insulation- because it does not take up precious internal space, which is always in short supply in dachas and rural dwellings. In addition to thermal protection of the facade plane, special attention should be paid to preventing heat from escaping through the corners.

They are the most problematic points in any home; Now you can find out which solutions to all these problems should be preferred.

What should you use to insulate?

Insulation for a frame house cannot be bulk; standard technology involves the use of only tiles or rolls. The difference is not only that “one is put down, the other is unwound.” Technologists are aware of the differences in nominal thickness. Typically, increasing the layer thickness increases the energy efficiency of the material.

But it is worth remembering that even a material that is impeccable in itself can be used incorrectly, and this immediately devalues ​​all the advantages. Therefore, it is better to either turn to professionals, or study the slightest subtleties and nuances of each coating.

The vast majority of amateur builders and official firms use the “brilliant four”:

• mineral wool;
• expanded polystyrene;
• mineral slabs;
• isolon.

There are many other options, the main division of which is carried out by chemical nature (organic or inorganic substances in the base) or by structure - solid blocks and bulk substances. You can even choose expanded clay, metallurgical slag and other bulk reagents. But the problem with this solution is the gradual shrinkage of the thermal protection layer. You will have to thoroughly compact the layer being laid, and not just fill the entire volume of the wall, floor, and so on with the selected composition. Slab materials do not cause such problems - but they also have their pitfalls.

So, using mineral wool in its pure form for external insulation of walls is pointless: it will not hold up well and will retain its thermal properties only until the first rain or snow. A prerequisite for success is attachment to a special structure of bars packed vertically. Each beam is placed only where the border between the mineral wool slabs passes. You should also take care of external protection from getting wet.

When working, it is important to wear respiratory protection, wear special glasses and not take off gloves.

Polystyrene foam is an organic substance. Its undoubted advantages are:

• low specific gravity;
• protecting walls from strong winds;
• exclusion of rotting.

But these advantages also have a downside: high fire risks. Therefore, it is impossible to decorate walls with foam plastic that has not undergone special treatment.

Mineral wool is absolutely not prone to ignition. A similar advantage can be obtained by using basalt wool, but it also has a significant advantage - ease of processing and perfect safety for builders.

Many people call the use of penoizol the ideal solution.

But it also has weak points - after a few years, areas will form where the material will not fit tightly. Therefore, heat loss will increase sharply. The liquid version of the coating has more powerful adhesion and lasts 50–60 years (a guarantee is provided for this period). The disadvantage, however, is also obvious - without special equipment it will not be possible to achieve success. But penoizol is in any case acceptable for retaining heat in the floor, roof and walls.

Internal insulation of walls of frame buildings using rolled materials is impossible. More precisely, it will be possible to attach them to the walls, but then the walls themselves will shrink, and the thermal insulation will inevitably be damaged. Regardless of the option chosen, and whether the work is done inside or outside the house, it must be carried out very carefully. It is useful to remember this whenever the thought arises of saving money by working on your own. If among all the materials the choice fell on penoizol, its installation is preceded by the installation of profiles.

Frame structures are rarely insulated with expanded clay, and even its low cost does not justify this choice. Yes, the material is very dense and does not absorb water well. But if it has already absorbed liquid, its release will be very slow. Expanded clay is very heavy, and even with a minimum density in dry form, it puts pressure on the walls and foundation very strongly. This circumstance will have to be taken into account during external finishing, choosing the most durable solutions for it.

But the main thing is not even this, but the fact that expanded clay is three times worse in thermal qualities than mineral wool and polystyrene foam. Therefore, you will definitely have to use layers of waterproofing and vapor barrier. Insulation with stone wool also competes strongly with this material. Working with its slabs is a pleasure; there is no need for complex tools. Cutting into the required fragments is done with a knife or saw with fine teeth.

Please note: stone wool blocks should not be compressed, tamped or squeezed. This will definitely lead to negative consequences. You also need to use ecowool wisely. So, in its pure form, ecological wool is very flammable, but if you mix it with brown and boric acid, the level of fire hazard will sharply decrease. In addition, such processing will avoid interest from microscopic organisms and certain animal species.

Near the surface, ecowool can contain up to 20% water (by weight) and retain its basic insulating properties.

When the material dries, it fully restores functionality. People will also find such advantages as an optimal microclimate, suppression of extraneous sounds, absence of seams and sanitary safety to be attractive. As for possible problems, they are:

• you will have to limit yourself to vertical backfilling in order to guarantee thermal protection;
• You will definitely need specialized equipment;
• if the fastening control was poor, the material may settle;
• Ecowool is not very appropriate where high humidity may be present.

Insulating frame houses with sawdust is another traditional, even centuries-old technology. But there is no reason to consider it exclusively primitive, as modern people often do. Careful consideration of the characteristics of a material makes it possible to advantageously embody its positive features and weaken its negative ones. The undoubted advantage of sawdust is its natural origin, affordable price and decent heat retention. You just need to deal with the risk of fire and the establishment of rodents in the material.

Antiseptic components, lime, clay, gypsum or cement help solve such problems.

Important: when choosing an additive for sawdust, you should pay attention to how hygroscopic it is.

In many places, high humidity can lead to very unpleasant consequences. Sawdust of a large fraction is usually used for the rough insulating layer, and heat retention is mainly ensured by a finer substance. When purchasing or preparing yourself, you should pay attention to the dryness of the material; the quality of thermal protection depends on it.

Adherents of modern materials and the latest technologies can insulate frame houses with extruded polystyrene foam. It is quite widely used when working on floors, including:

• over unheated basements and technical undergrounds;
• under attic floors;
• to enhance the acoustic protection of structures separating the floors of the house.

Typically, on the floors of frame houses, polystyrene foam is placed between the joists; at the request of the owners or craftsmen, it can be mounted under a reinforced screed made of cement and sand. The disadvantage of the material (easily eliminated, however, with a careful approach) is the need to strictly observe the specified gaps between the plates. Expanding when heated, polystyrene foam can be damaged - to prevent such a development of events, gaps are needed. It is important to remember that this synthetic substance is flammable and should be used with caution.

It is unacceptable to glue it to mixtures containing any flammable or simply caustic component.

In addition to insulation, it is worth remembering that a frame house must be provided with reliable, well-designed ventilation.

Fresh air is always brought in from utility rooms, and the flow is carried out under the doors separating the rooms. If you do not take care of the presence of a gap under them, then not only freshness, but also uniform distribution of heat in the home will not be achieved. When it is not possible to form such a gap, the following come to the rescue:

• special channels for flow;
• bars across the wall;
• separate channels for the passage of air into a specific room.

Specifications

The more monolithic the insulation layer, the more stable it usually retains heat. Because It is worth paying primary attention to the density of the structure, it is much more important than a big name or a whole series of certificates. The only particularly lightweight material that deserves attention is polystyrene foam (including its modification such as polystyrene foam). Even mineral wool belongs to the simply light category, although its specific gravity can vary widely. It is this circumstance that allows you to choose the optimal solution for a wide variety of conditions and situations.

If you want maximum cold blocking (in living rooms and on the floor), you need to use the thickest versions. For a non-residential attic, the requirements are lower. With a density of 75 kg per 1 cubic meter. m. cotton insulation is suitable only on surfaces that carry a relatively light load, as well as for thermal protection of pipes.

Brand P-125 is already more worthy; it can be used in different procedures:

• covering ceilings and floors;
• thermal insulation of walls;
• thermal protection of partitions;
• suppression of external noise.

Cotton wool of category PZh-175 has increased rigidity and is not used in frame houses, to a greater extent it is used in stone and concrete buildings. If you plan to cover the walls with siding, you can use basalt wool with a density of 40 to 90 kg per 1 cubic meter. m. Moreover, the densest material is recommended to be used in the upper parts of the walls. For plaster, experts advise using cotton wool with a specific gravity of 140–160 kg per 1 cubic meter. m. The requirements for insulation materials used in the interior of a frame house are less stringent.

When the home is covered with a pitched roof, the optimal parameters are 30–45 kg per 1 cubic meter. m, and if you plan to insulate the attic, the lower bar is already 35 kg.

The minimum value for mineral wool under a flat roof is five times higher, and for expanded polystyrene it is much more gentle, only 40 kg per 1 cubic meter. m maximum. In floors, loose insulation can only be used when laying between joists. Otherwise, the thermal protection will be a mechanically loaded element, which will negatively affect its characteristics.

Residents of frame houses naturally strive to ensure that their habitats are not only warm, but also environmentally friendly; errors in the selection of insulation can prevent the achievement of this goal. Until recently, it was possible to find an environmentally friendly method of thermal protection only in elite areas, but now such schemes have become much more accessible. Quite predictably, natural fibers take first place:

• woody;
• linen;
• hemp and some others.

The advantage of such substances is the zero degree of allergic and toxicological risk. The softness of the structure makes it difficult for individual components to penetrate into the external space. There is absolutely no place for mineral and glass wool in an environmentally friendly home. Insignificant shards of glass and stone fibers cannot be seen without a magnifying glass. But they can cause significant harm to health.

Important: no matter how great the desire for cleanliness and health protection, this is not a reason to refuse antiseptic treatment of a number of materials – where it is really needed.

Fire retardants are most often made from borax, a natural mineral that is completely safe. The vast majority of thermal protection components, however, do not pose a danger only under strictly specified conditions. One of them is always maintaining the integrity of the insulating “pie”, from which one or another substance cannot normally escape. Linen insulation is relatively cheap and at the same time quite normal, based on data obtained from medical studies in different countries.

Peat blocks are now becoming increasingly in demand in frame construction. 1 cu. m of such material costs approximately 3 thousand rubles, and it will last for 75 years, all this time being a sharply unfavorable place for microbes. What is important in our troubled era, such insulation can reduce the entry of penetrating radiation into the house by 80%. The only problem is that there is still little operating experience, and it is unclear how peat blocks will behave in different conditions after many years.

Cork structures are easily placed under wallpaper, on interior walls and under the floor; but due to the very high price, it is unlikely that many people will be able to appreciate their quality in the foreseeable future.

Review of manufacturers

Reviews allow us to appreciate not only the different types of insulation materials, but also the professionalism and integrity of individual companies.

Attention: you need to take into account that we will only talk about the truly best of the best companies that have shown all their capabilities over the years of competition.

Firm "Rockwall" supplies the market with fireproof thermal insulation made from stone wool. It places emphasis on ensuring the highest environmental and sanitary performance of its products. You can use this mineral wool as part of thermal protection:

• pipes;
• facade walls;
• room partitions;
• roofing structures;
• areas experiencing intense loads.

100 mm of such a slab is enough to replace almost 2 m of brickwork.

French corporation "Isover" sells glass wool to its consumers in roll, slab or matte configurations. Of course, environmental safety is somewhat less, but the cost of the products is noticeably lower and optimal fire-fighting properties are guaranteed. The level of thermal conductivity also meets the necessary requirements. The company's line includes pressed materials that are easy to install even without the use of fasteners.

Glass wool is also supplied under the brand name URSA, which uses significantly less phenol in production, and in some cases got rid of it altogether. The product range includes:

• slabs of moderate rigidity;
• products adapted for medical and children's organizations;
• hydrophobic structures of increased density;
• products resistant to deforming loads.

Calculations

Regardless of what specific substance is used, the thickness of the insulation must be carefully calculated. If you miscalculate this indicator, you will end up with either an insufficient effect or excessively high costs for purchasing thermal protection and working with it. When the work is entrusted to a professional team, you still need to control the measurements and calculations made by it. As practice shows, installers left without supervision, making sure that no one is checking them, will sooner or later “make a mistake” in their favor.

The main role in the calculations is played by indicators such as thermal conductivity and thermal resistance.

Glass wool has a very high resistance to heat loss - but its disadvantages prevent the widespread use of this material. When making calculations, it is worth focusing on the climatic properties of a certain area. Thus, in Moscow and its environs, the recommended layer of most good insulation materials does not exceed 0.2 m. If you use such a quantity in the Far North, the result will be disastrous for residents.

A standard formula of the form δut = (R – 0.16 – δ1/λ1 – δ2/λ2 – δi/λi) × λut has the following components (sequentially):

• thermal resistance of structures in a specific area;
• total thickness of all layers;
• coefficient of thermal conductivity;
• the ability of insulation to transmit heat.

Raw materials and tools

When the type of insulation has been chosen, the calculations have been made, it’s time to get ready for work properly. It is imperative to select the necessary tools as carefully as possible, taking into account the slightest nuances.

• With the dry insulation option, the “raw material” can be considered, along with the selected thermal protection, timber or metal structures of the frame being created. It is also useful to choose decorative materials, waterproofing films, membranes, and vapor barriers that match the material.
• The “wet” scheme is implemented using water-based adhesives.

Typical tools for insulating walls and roofs include:

• screwdriver;
• guns for applying polyurethane foam;
• hammers;
• jigsaws for precise cutting of wood and metal;
• perforator;

• spatulas;
• hydraulic levels;
• roulette;
• metal scissors;
• containers for preparing solutions, and so on.

The exact set cannot be predicted in advance, because it greatly depends on the chosen technology, on the nuances of the frame house and the amount of work. In any case, it is worth trying to purchase high-quality tools and supplies. All devices purchased specifically or already on hand should be carefully checked before starting work. Otherwise, it will not be possible to guarantee the quality and safety of manipulations during insulation. In almost all cases, craftsmen benefit from a square: it is able to both mark precise right angles and measure the actual angles formed by the sides of the part.

Among all the hammers, the machinist's type is best suited.

It is suitable for processing any surfaces. On the one hand, such a tool is smooth and allows you to strike, and on the other, it is pointed, like a chisel. If you have to dismantle building elements and structures, you need a nail puller. You can separate polystyrene foam and other insulating and decorative elements into pieces using fine-tooth saws. The teeth should be specially set and sharpened in a special way.

For the preparation of building mixtures, only mixers with a spiral-shaped working part made of strong steel grades are quite suitable. Using rollers, it is easy to apply primers and a variety of paints, even if the surface is very rough or rough. To apply the adhesive solution for subsequent implementation of the reinforcing mesh, it is recommended to use Swiss ironing tools with teeth. The optimal tooth size is 8 x 8 or 10 x 10 mm, it is determined by the manufacturer of the façade systems.

Self-coverage

In any case, the step-by-step instructions require installing a layer that protects from moisture. The only exception is made for those situations where such protection is already in place outside (or inside). The reason is simple - two-way blocking of water deprives it of outlet. The liquid will accumulate inside the walls and gradually destroy them.

The first step is usually to measure the external surfaces and cut the waterproofing material according to their size.

Next comes work with the vapor barrier. This point cannot be avoided even when hydrophobic or neutral substances that tolerate contact with water are used for insulation. After all, besides them, the “pie” also includes other parts that are much more sensitive to getting wet. When insulating inside and outside, it would be correct to use a special film or foamed polyethylene to contain water vapor. Such materials are attached to the frame racks, ensuring maximum tight pressure against the insulation.

Important: wrapping thermal protection blocks in film is a violation of the standard scheme - until all components of the frame, without exception, are covered from water, the work cannot be considered completed.

Only when all this is finished do they begin to work with the filler itself.

At the same time, safety requirements are strictly observed, especially relevant when choosing mineral or glass wool.

The final step is to cover the walls from the inside. In terms of the sum of their qualities, plasterboard and oriented particle boards will be unrivaled. It is recommended to install gypsum boards if the frame is perfectly flat, then the outer surface will be smooth. But OSB, thanks to its rigidity, will cope with flaws as efficiently as possible. But in any case, this is only preparation for the real finishing touches.

Master classes from professionals

Master classes organized by professionals allow you to obtain the latest and adequate information on all problems of insulation and related topics. As a result of the consultation, it will become clear what the width of the frame board should be in a certain case, and how to calculate the thickness of a fundamentally new material.

Experienced craftsmen understand safety measures and the storage and transportation of each insulating coating better than ordinary amateur builders. Many mistakes are made when attaching structures, drawing up diagrams and determining the sequence of layers in the “pie”. But communicating with knowledgeable people helps correct this situation.

When mineral wool is used, try to prevent condensation coming from warm rooms from getting on it. But waterproofing and vapor barrier also contain many pitfalls. The choice of material for cladding is often dictated by tradition, personal tastes or stereotypes - but a well-thought-out design is much more pleasant. Professionals will tell you when you can use natural insulation, and when it is better to use artificial ones. It is very important to understand the compatibility of materials with each other: master classes again help here.

To find out which insulation retains heat better, see the following video.

The costs of building a frame house in comparison with concrete structures look more pragmatic, and the level of heat loss directly depends on the insulation filling the voids in the walls and floor. In addition, most materials simultaneously have other properties (fire resistance, noise insulation, moisture resistance, etc.).

The review presents the best insulation materials used in the construction of frame buildings for various purposes. The rating was formed based on the characteristics of this product and the opinions of professional builders who have been working with a certain group of insulation materials for more than one year. Feedback from owners was also taken into account, conveying invaluable experience in using a certain material over a long period of time.

The best mineral insulation for a frame house

5 Expanded clay

High environmental friendliness
Average price: 243 rub. (0.07 m³)
Rating (2019): 4.5

Lightweight porous clay granules are quite suitable for insulation, although they are in less demand (due to the high price) than mineral wool. Backfilling of frame walls, carried out using a special technique, is used much less frequently than insulation of floors and ceilings using expanded clay. This is explained by the thermal conductivity of the material (no more than 0.14 W/m*K). To ensure better thermal insulation, a layer of 150 mm will be required, which is not entirely advisable.

Since this insulation has the ability to absorb moisture and is not very willing to part with it, the ineffectiveness of the installed vapor barrier materials significantly reduces thermal conductivity. The simple technology of application and low price of expanded clay attracts owners of frame houses who plan to assemble it themselves. Reviews from those who have already used this insulation note the need for the correct choice of density and fraction, on which, in turn, the performance characteristics of the material significantly depend.

4 Slag wool

Affordable price. High thermal insulation characteristics
Average price: 166 rub. (0.12 m³)
Rating (2019): 4.7

Having the best thermal insulation properties, slag wool is used to insulate walls, roofs and floors in frame buildings. Although the material cannot boast of environmental friendliness, it is very popular, which is largely determined by its special properties. The insulation is made from slag waste from metallurgy, it has a low cost, and at the same time, is practically not inferior in terms of thermal insulation characteristics to more expensive analogues. The light weight of the material and ease of cutting allow you to perform insulation work on any surface.

The hygroscopicity of this insulation is not an obstacle to its use for thermal insulation of a frame house - you just need to ensure high-quality vapor barrier. If all recommendations regarding the installation of slag wool are followed, it can last for quite a long period of time - 50 years, at least. Negative reviews indicate the presence on the market of a low-quality product, manufactured in violation of technology and in artisanal conditions. When purchasing this building material from a trusted supplier, you can rest assured that this insulation provides all the declared characteristics.

3 Foam glass

Durability. Lowest thermal conductivity

Rating (2019): 4.8

Judging by the reviews, foam glass has the best insulating and energy-saving properties. To insulate the walls of a frame house, the block form of this material is preferably chosen. Its use eliminates the need for an additional layer of vapor barrier, since this insulation has increased resistance to moisture. Among other things, foam glass demonstrates the best strength and durability, which guarantees a high level of comfort in all weather conditions for 100 years.

When choosing this insulation for a home, owners are primarily guided by safety and thermal conductivity indicators, which foam glass has among the best. This material is non-flammable, absolutely environmentally friendly, biologically stable, and the heat retention coefficient is only 0.04 W/m*K. The only drawback many see is that the price is too high. However, when constructing new frame-type structures, owners are increasingly choosing this insulation.

2 Glass wool

The most popular insulation
Average price: 549 rub. (0.375 m³)
Rating (2019): 4.9

Glass wool is also widely used in construction. The choice of this insulation is primarily due to its affordable cost and the best technical characteristics that provide the necessary comfortable living conditions. The only disadvantage of this material, judging by the reviews, is its “prickliness”, but if you follow the recommendations for use, all undesirable aspects can be avoided. Glass wool is easily laid along the joists during the process of insulating interfloor ceilings, and in frame walls it qualitatively fills all voids, leaving no room for heat loss.

The low thermal conductivity coefficient of this insulation guarantees maximum satisfaction of the requirements laid down in the concept of comfortable housing. When building a frame house, an important factor when choosing is the non-combustibility of materials, and one of the characteristics of glass wool is precisely its high fire resistance. At the same time, pests (rodents) and microorganisms are not able to survive in a space filled with this insulation. Considering the ability of glass wool to absorb moisture, you should take the installation of vapor and waterproofing very seriously - the service life of this material directly depends on the quality of this work.

1 Basalt wool

Better moisture resistance. Long service life
Average price: 890 rub. (0.576 m³)
Rating (2019): 5.0

It is considered one of the most popular insulation materials used in arranging a frame house. Its base consists of various rocks and rocks, including basalt. This material is characterized by increased strength and better fire resistance, which guarantees excellent fire safety. Basalt wool has low thermal conductivity, which minimizes losses and significantly reduces heating costs.

Since basalt wool is not able to absorb moisture, it is the best choice for filling the frame skeleton of a house. This material is very simple and easy to install, which is confirmed in their reviews by users who independently insulated walls and floors with stone wool. The environmental friendliness of the insulation, its biological and chemical stability, as well as the constancy of its original properties throughout its service life (at least 50 years) are also noted.

Modern insulation materials, although they have a number of advantages, are still less environmentally friendly compared to natural-based insulation materials, and also require additional costs for the installation of forced ventilation systems.

5 Penofol

Unique reflective characteristics. High coefficient of thermal resistance
Average price: 400 rub. (9 m² with a thickness of 10 mm)
Rating (2019): 4.3

Rolled composite material has a high reflective effect and is used in frame houses mostly for insulation of ceilings and floors, and for thermal insulation of walls its use is only advisable in combination with another material (the same polystyrene or stone wool). At the same time, penofol also provides sound insulation, does not emit harmful substances and has a high coefficient of thermal resistance. In addition, this material is so easy to install that it does not cause any difficulties when installing it yourself.

In reviews, owners point out its practicality - with a small thickness, penofol significantly enhances the effectiveness of the insulation used with it due to a layer of aluminum foil and polyethylene with bubbles of inert gas frozen in it, which does not conduct heat at all. The ability to reflect not only heat waves, but also radio signals, as well as some types of other radiation, is noted. Among the entire variety of materials for thermal insulation, only penofol has these properties, which, together with its reasonable price, only contributes to its popularity in the building materials market.

4 Polyurethane foam

Long service life. High material efficiency
Average price: 247 rub. (0.45 l)
Rating (2019): 4.5

Frame walls are filled with polyurethane foam by spraying, and if not for the high cost of the material, it would easily displace most of the insulation materials from the market. Good insulating properties, resistance to fire, pathogenic microorganisms, long service life (at least 50 years) - these are just some of the advantages of this insulation.

Given the absolute resistance to moisture, insulation of the walls of a residential building should be carried out in parallel with the installation of ventilation systems. Unique thermal conductivity indicators (from 0.019 to 0.03 W/m*K) not only allow you to significantly save on heating the room in winter, but also prevent summer heat from entering the house. The best efficiency has been proven by many years of operating experience by owners from different regions. And judging by their reviews, this insulation is worth the money spent on its installation.

3 Penoizol

Best installation speed
Average price: 925 rub. (0.5 m³)
Rating (2019): 4.6

This material is one of the fastest insulation materials - with well-coordinated team work, the frame walls of a house, including interfloor ceilings, can easily be insulated within one day. The advantage of penoizol is that the monolith fills absolutely all cavities and, after hardening, acquires high thermal insulation properties that will serve the owner for decades, since the material is located in the space between the walls and is completely protected from the influence of external factors.

Based on the reviews of the owners, even after five or more heating seasons that have passed since the installation of this insulation, there were no complaints related to the properties of penoizol. An artificial ventilation system with such insulation is a prerequisite for residential premises. Of course, adherence to the technology for producing carbamide insulation and the quality of raw materials play a huge role, but with strict implementation of the regulations, the result is invariably positive.

2 XPS (extruded polystyrene foam)

High material efficiency
Average price: 1250 rub. (5.6 m²)
Rating (2019): 4.8

XPS is most widely used as a material for insulating interfloor ceilings and the floor of the first floor. Its thermal conductivity makes it possible to effectively cut off the flowing cold from the base of the building or the basement located under the residential floor. Its use in the attic part of the house is no less effective. The seams between the plates are filled with polyurethane foam, which makes the insulation layer monolithic.

Reviews from owners who have used XPS as thermal insulation note the high efficiency of the material - 50 mm thick slabs have characteristics similar to 925 mm brickwork. Such performance indicators will not leave any owner indifferent, and the cost of this material (it is not the most affordable) against this background becomes a secondary matter. It is strongly recommended to install a supply and exhaust ventilation system. In its absence, the internal walls of the house will constantly become damp, since the material does not allow moisture to pass through at all.

1 Foam

The most popular insulation. Affordable price
Average price: 620 rub. (0.4 m³)
Rating (2019): 5.0

One of the most convenient insulation materials to install is polystyrene foam, which also has all the characteristics necessary for high-quality thermal insulation. This material has the most affordable price and a number of operational advantages, so it is often used to insulate the frames of private houses. It does not absorb moisture and does not change its original shape over time. Contrary to popular belief, polystyrene foam is not susceptible to attacks by rodents, which is confirmed in their reviews by users who insulated the walls of their house several years ago and during the entire period of operation never found such damage to the insulation layer.

For optimal thermal insulation effect, you should follow all installation rules and take a responsible approach to choosing the manufacturer of this insulation. High-quality foam plastic must, among other things, meet fire safety requirements, for which it is treated with a special substance - a fire retardant. Depending on what will be insulated - the floor or walls of a frame house, you should choose types of foam plastic of different densities. Thermal insulation with foam chips is no less successful. It is simply poured into the cavity of the structure. This material is practically devoid of vapor permeability, so residential premises must be equipped with an effective forced ventilation system.

5 Sawdust

The best cost of insulation
Average price: 81 rub. (20 l)
Rating (2019): 4.5

This insulation has an obscenely affordable price, which is why many treat it with rather high irony. In addition, sawdust can act as an excellent habitat for both insects and field rodents, unless special antiseptic treatment of the material is carried out. The use of different francs or wood pellets (after special processing) gives a low percentage of shrinkage and a high density of insulation. In this case, you should monitor the absence of impurities and the moisture level of the building material before filling the voids of frame walls or floors with it.

Reviews from owners who have chosen this most affordable insulation note its high breathability, vapor permeability and low heat transfer, depending on many factors, including the degree of filling of voids and compaction, as well as the type of wood from which the sawdust is actually made.

4 Fiberboard

Withstands structural loads. The most durable
Average price: 1770 rub. (1.8 m² at 100 mm thickness)
Rating (2019): 4.7

This insulation is a universal building material, which, in addition to everything, provides good sound insulation properties and also easily maintains climatic balance in the room. Made from wood wool and Portland cement, this modern composite material gets rid of the main drawback of environmentally friendly insulation - poor fire resistance. A cubic meter of insulation weighs about 300 kg, which allows you to insulate not only the floor, but also frame walls.

Despite the not the best thermal conductivity coefficient (0.063 W/m*K), the demand for fiberboard is steadily growing, since its other characteristics look more advantageous in comparison with other materials in this category. Owner reviews also note the durability and wear resistance of fiberboard. Due to its high rigidity, it can easily withstand structural loads, which can significantly reduce the cost of constructing a frame house.

3 Cork agglomerate

Easy. The most fireproof material among natural insulation materials
Average price: 1120 rub. (3 m² with a thickness of 50 mm)
Rating (2019): 4.8

Technical cork, made from natural cork oak using resin from the same tree, is one of the highest quality and environmentally friendly insulation materials. Agglomerate sheets are available in different thicknesses (10, 25, 50 and 100 mm), which allows you to choose the most suitable mats for walls, floors or ceilings. Due to the relatively high cost of the material, it is used extremely rarely for insulation of frame buildings. It is mainly used to insulate flat roofs (while also serving as a finishing material) and floors.

Reviews from owners who preferred cork agglomerate (essentially a natural and environmentally friendly material) note the high performance characteristics of the insulation - it practically does not burn, and rodents avoid it. In addition, cork has high sound-absorbing properties (used for finishing professional recording studios) and does not bear much load on the structure of the house - one cubic meter of agglomerate weighs no more than 130 kg. In addition, its thermal conductivity is 0.040 W/m*K, which beneficially complements all other advantages of the agglomerate.

2 FLAXAN

The best modern insulation. Highest class of environmental safety
Average price: 2600 rub. (0.5m³)
Rating (2019): 4.8

A modern material for insulating walls, floors, and roofs of houses, including frame houses, is distinguished by excellent insulating properties and has a number of unsurpassed characteristics. Flaxan appeared relatively recently on the market, but has already become in demand among domestic developers of luxury housing. Unfortunately, its cost is such that not everyone can afford it. However, its use in residential premises most complies with environmental safety requirements - the Dutch research institute NIBE recognized it as the best insulation, having the highest environmental class 1 “A”, since it has absolutely no negative impact on people living in the room.

The thermal conductivity coefficient of a 100 mm thick jute-linen mat is 0.034 W/m*K, which makes this material quite a worthy insulation material for the walls and floors of frame buildings. Despite the fact that Flaxan belongs to highly flammable materials (category “G” 4), this does not at all affect its steadily growing demand. In addition, in addition to thermal protection of the house, this material provides, judging by reviews, a fairly good level of noise insulation, and also has a fairly decent service life without loss of its characteristics - at least 75 years.

1 Cellulose wool (ecowool)

Provides self-regulation of the internal climate. Best level of thermal insulation and acoustic comfort
Average price: 579 rub. (15 kg)
Rating (2019): 5.0

Despite all its unpretentiousness (ecowool is made from recycled materials) and affordable cost, this insulation has one of the best thermal conductivity indicators - 0.042 W/m*K. It directly depends on the moisture that cellulose wool absorbs like a sponge. This material is applied by spraying a layer of the required thickness (this is much more economical in consumption), and for a frame structure it is one of the most preferred materials - ease of installation, the price of insulation and thermal insulation characteristics have a strong influence on the preferences of domestic developers.

In a frame house, using ecowool, you can also insulate the floors located on the joists. The ability to easily absorb and release moisture creates a self-regulating microclimate in the premises, ideal for humans, especially those suffering from various allergic manifestations. Some reviews, in addition to this feature and low thermal conductivity, also note the excellent acoustic properties of ecowool. The insulation is capable of absorbing up to 63 dB of noise coming from outside, providing residents of such a house with the level of comfort of elite-class housing.

An important point in the process of building a house on a frame basis is. High-quality thermal insulation guarantees the maintenance of optimal temperature conditions in the room. Literate is a challenging task. There are many options for protecting your home, and it is possible to insulate the walls both outside and inside.

Which insulation to choose for a frame house?

This is a pressing issue, because a frame-based structure has a high loss rate. With the help of high-quality material, you can provide maximum protection against heat transfer.

Foam insulation

Foam plastic is considered one of the most popular insulating materials. The popularity is due to the advantages:

• environmental Safety;
• affordable price;
• a light weight;
• does not require a special moisture-proof coating;
• ease of installation;
• there is no need for additional insulation.

This cheap insulation for a frame house also has its drawbacks. It ignites easily, has low noise insulation and is very brittle.

Tip: To insulate a building with an area of ​​6 m2 with foam plastic, you need about 3 m2 of material, the thickness of which is 50 mm.

Polystyrene foam and mineral wool

Mineral wool as insulation

High-quality insulator, which is in growing demand, is dense compressed slabs. They have a rectangular shape and are easy to cut, which allows you to create a piece of insulation of the required size using a saw and knife.

Mineral wool is produced by heat treatment and the process of pressing basalt or blast furnace slag. The structure in the form of fibers traps air, so a protective barrier is formed for the penetration of cold air.

Mineral wool is different:

• light weight;
• good sound insulation;
• fire resistance;
• durability;
• tolerate deformation well;
• excellent thermal insulation.

The material contains substances harmful to human health. Small particles are especially dangerous; they can penetrate through the respiratory tract and cause various diseases.

Advice: To prevent the negative influence of cotton wool, the walls of the building must be covered from the inside with special vapor barrier films.

Mineral wool is susceptible to the negative influence of moisture, under the influence of which it loses its excellent thermal insulation properties and succumbs to rot. Therefore, when thermally insulating walls, the openings of the frame block should be protected from the outside with special waterproofing materials.

Insulation of the facade of a frame house using Rockwool insulation - step by step

Insulating walls with mineral wool is not a difficult task:

1. It is necessary to make a vapor barrier, since wood breathes, the insulation must be protected from condensation.
2. Mineral wool is placed between the frame posts. It is recommended to mark and cut the slabs of material with a margin.
3. Install thermal insulation between the posts as tightly as possible.
4. Mineral wool strips of small width should be used to cover the joints between the thermal insulation and the drains of the frame.

The same method can be used to insulate the outer surfaces of a building. Only in this case is it necessary to apply a waterproofing film over the mineral wool.

When asked which insulation is best for a frame house, reviews confirm this; experts are inclined towards mineral wool, subject to proper installation.

Glass wool for home insulation

Fiber material has been used in construction for a long time. Glass wool is produced by melting waste from glass production, limestone, soda, sand, borax and dolomite. The material is produced in the form of plates and rolls.

When contacting the material, it is necessary to use protective items: gloves, respirators and goggles, since sharp and thin fibers of glass wool pose a danger to humans.

Glass wool has its own advantages:

• excellent heat resistance;
• fire resistance;
• low hygroscopicity;
• resistance to chemical degradation.

Wall insulation for a frame house has excellent thermal insulation properties and does not emit harmful toxic substances in the event of a fire. The material is inexpensive, so it is popular.

When insulating a room, it is recommended to cover the glass wool with a windproof film. This operation allows heat to remain inside the building for a long period of time.

Ecowool insulation

High-quality eco-friendly insulation for a frame house is a modern material made from cellulose.

It has a number of features:

• To carry out the work, you need a special device, which during the insulation process mixes the insulation with water, and then drives the material into the wall cavity - this method is called wet;
• the dry method involves the process of pouring material into the frame space and then compacting it;
• the insulation is not afraid of high humidity, so there is no need to lay a special film.

This is not the best insulation for a frame house, since ecowool is very expensive and it is recommended to use the services of specialists to work with it.

The thickness of the insulation must be calculated taking into account the requirements for thermal insulation. This affects the amount of material that needs to be purchased. It is recommended to invite a professional who will take the necessary measurements and be able to calculate the exact amount of mineral wool required for a particular frame house.

Polyurethane foam or penoizol - quality material

Reliable and excellent insulation consists of two components that are mixed together. The resulting mixture is used to fill the cells of a frame-type structure. The result is a monolithic surface. Working with the material can be compared to manipulations carried out with polyurethane foam.

PPU or polyurethane foam has excellent thermal insulation properties, but requires certain skills, experience and knowledge. Therefore, professionals work with the material. The cost of polyurethane foam is relatively high, so if the question is which insulation is better to insulate a frame house and at the same time save money, then you should abandon polyurethane foam.

Thermal conductivity of insulation and building materials

Clay - a proven method

To insulate the room, you can use ordinary clay. This is the most environmentally friendly method. To carry out the work, special clay is used, which has a specific fat content coefficient. Low-fat material does not have the necessary adhesion, so plaster made from it will crumble and crack after a certain period of time.

After creating a thick mixture of clay, you can test its suitability by rolling a ball and then pressing it between two boards:

• if the ball is cracked by about 50%, then sand should be added;
• if the cracks are about 30%, then the plaster is ideal for further use;
• if the ball crumbles, then the material is not at all suitable for high-quality work.

Clay mortar is the answer to the question of which insulation is best for a frame house; reviews from people who have used this method confirm this if the naturalness of the materials is important to the owner of the house.

Worth knowing: There is no specific method for making clay mortar. The composition of the components: lime, cement, water, sawdust, sand, clay, and their ratio may be different.

The technique for working with the material is similar to manipulating ordinary plaster:

1. the wall is covered with a primer;
2. beacons are installed;
3. a rough layer of plaster is applied, the thickness of which should not exceed five centimeters;
4. After the previous layer has dried, a finishing layer is applied and finishing work is carried out.

Fibrolite – quality and reliability

Fiberboards are produced by drying and pressing wood shavings, which are mixed with a binder: magnesium salt or Portland cement. To best preserve the thermal insulation characteristics, it is recommended to use additional waterproofing. The material is used to insulate internal walls and ceilings.

The popularity of fiberboard is determined by its excellent performance characteristics:

• is fireproof due to the presence of special impregnation with binders;
• has excellent moisture resistance and is able to withstand constant and regular exposure to high humidity;
• the ability to withstand various types of deformation. Pressed wood chips act as a damper, and cement or other binders provide them with stability;
• is not biologically active, therefore it is not subject to the unwanted process of decay, since the spread of microorganisms and insects does not occur within the material;
• has a high sound insulation rate;
• is environmentally friendly;
• able to withstand severe cold and frost, therefore it is actively used in various climatic zones;
• is durable - service life is at least 50 years.

Sawdust - old method

How to choose insulation for a frame house if there are no specialized materials available and the goal is to save a lot? The answer is quite simple - it's sawdust. Thermal insulation is not produced by sawdust itself, but by a mixture with other building materials: cement, antiseptic or lime.

An approximate technology for preparing insulation is as follows:

When pouring water, it is recommended to use a watering can to evenly moisten the resulting mixture.

In most cases, the space between the beams or beams in the floor is filled with sawdust. Sometimes they are used to insulate walls. In this case, the composition is poured in small layers and compacted thoroughly.

This method of thermal insulation has disadvantages:

• labor intensity during work;
• high degree of fire hazard;
• low efficiency rate;
• settling of material over time inside the walls.

The method may be more effective for a frame house if expanded clay is used.

There is a large selection of materials with which you can insulate a frame house. They differ in their scope of application: inside and outside, method of operation, cost, efficiency and environmental friendliness.

What insulation should I use in a frame house?

The decision remains with the owner of the frame housing. The most environmentally friendly and cheapest method is clay plaster. Modern methods of work allow us to perform work with the highest quality and aesthetics.

Video Insulation of a frame house

A frame house is an attractive modern alternative to brick, timber and block houses. Due to the warm climate in Canada, the USA and European countries, such houses are the main type of residential buildings, and due to the low cost of construction and ease of installation of the frame, they have become popular in Russia.

The peculiarities of the Russian climate have made their own adjustments to frame technology, making insulation of the frame of a house an obligatory stage in construction, and due to the large number of insulation materials, making the right choice is becoming increasingly difficult.

After reading this article, you will learn:

• About the stages of construction and insulation of frame houses.
• What insulation materials can be used in the frame structure of houses.
• Where and what type of insulation can be used.
• What other materials are needed for frame construction?
• What insulation is better to buy for insulating a frame house?
• And a lot of other useful information.

Construction technology: general principles

Optimal temperature conditions are an important condition for a comfortable stay indoors in winter and summer. Therefore, the technology for constructing frame houses ultimately comes down to their insulation.

There are several construction technologies in nature, but the process of their construction comes down to the main stages that are inherent in almost all construction methods. The main essence of the technology is to conditionally divide the construction of a house into two parts:

1. Enclosing structure (floor, walls, roof);
2. Frame (load-bearing element of the structure).

Construction stages

1. Arrangement of the foundation. Since the frame is relatively light in weight, the foundation is made on piles or using a strip method made of concrete or brick.

2. Delivery of frame house elements to the installation site (beams 150*150, staples, screws, etc.).

3. Floor arrangement. To do this, beams are laid on the foundation, on which the assembled structures are installed. The foundation is waterproofed using mastic or roll materials. Then the floor covering is selected. Tile material, for example ISOPLAT, or OSB boards and insulation are well suited for these purposes.

4. Support beams are installed on the assembled floor and covered with sandwich panels. Galvanized fastening angles are used for all structural connections. At this stage, all external and internal panels are installed.

5. Using fasteners, roof trusses are mounted on the walls of the frame structure.

6. Roofing work. Well suited for roofing. This is a lightweight, strong, durable material consisting of fiberglass, granulate and modified bitumen, for which the manufacturer provides a guarantee of up to 60 years.

7. After vapor barrier membranes are stretched along the perimeter of the building walls and roof, which will protect the basalt wool from moisture.

8. Proceed to insulate the gaps of load-bearing frame structures with basalt wool (walls, floor, roof). The material is laid on the inside of the house, and then sealed with a vapor barrier membrane. In general, the insulation process looks like this:

9. Installation of windows, doors and laying of communications around the house (pipes and cables).

10. Laying communications around the house (pipes and cables) and finishing the interior walls with eurolining or any other finishing material.

A frame house can be assembled in a short time and does not require the use of special equipment. It is enough to follow the construction technology and use all the necessary materials, which you can buy from us at wholesale prices!

Types of materials for insulating frame houses

Currently, the following three types of materials are used for heat and sound insulation of frame houses, but not all of them can completely insulate frame houses:

Information block: What kind of insulation, and where it can be used, read below, in the description of each insulation.

Basalt wool

Mineral wool (glass wool)

Foam plastic (expanded polystyrene)

Polystyrene foam (expanded polystyrene) is a cheap, durable insulation material that is sold in the form of slabs of different sizes and thicknesses.

Polystyrene foam is a frozen foam mass consisting of 98% air and 2% polystyrene itself, resulting in a very light material.

The most popular manufacturers: PENOPLEX, URSA XPS (URSA), KNAUF Therm.

Plates made of polystyrene foam and extruded polystyrene foam are not used for wall insulation, due to the release of toxic substances during the operation of the house and vapor permeability. They can only be used to insulate the foundation if they plan to pour concrete under the house.

Other types of insulation (ecowool, sawdust and polyurethane foam)

These types of insulation have not been used in frame construction technology for a long time due to inefficiency or high cost (polyurethane foam), although there is a lot of reverse information on the Internet.

Therefore, when ordering the construction of a frame house, we would recommend that you pay attention to how your house will be insulated.

What thickness of thermal insulation is considered optimal?

To determine the thickness of the thermal insulation layer that will work effectively, you need to take into account two main factors:

• what material will be used?
• What climate is the house in?

For example, for the Krasnodar region it will be sufficient to use 2 layers of basalt wool (total thickness 100 mm), and in St. Petersburg and the Leningrad region 4-5 layers of a similar heat insulator (total thickness 150-200 mm) will be needed.

δout = R x λout

R- thermal resistance of the wall;

λut- thermal conductivity of the selected material.

The thermal resistance coefficient of residential buildings in the Leningrad region is 3.3.2 m2*0C/W. The thermal conductivity value can be found in the material certification documentation.

For example, to insulate the frame structure of a house, we use basalt wool.

The thermal conductivity of the material will be 0.045 W/m*0С. For this case we get the following calculation: δut = R x λut = 3.20 x 0.045 = 0.14 m.

Those. it turns out that for effective insulation and sound insulation of a building in the Leningrad region, the minimum thickness of the thermal insulation layer of basalt wool should be 150-200 mm.

What is the best insulation for a frame house?

The answer to this question is definitely one - it’s only basalt wool for insulating external walls, and preferably internal ones. It is the toughest, so it does not cake and does not sag over time, thereby isolating the house well from the environment, allowing it to “breathe”, releasing moisture to the outside.

As for glass wool, it can only be used in non-load-bearing surfaces and insulation of interior partitions, which will reduce construction costs. But there is one thing: if you compare the price of basalt slabs and mineral slabs (glass wool), then the price will not differ significantly, but the quality of the insulation in its properties and service life is significant.

Therefore, before choosing insulation for interior floors, you should ask yourself: Is it worth saving during construction? It's up to you to decide!

conclusions

Insulation of frame houses is one of the important stages of construction. In fact, only one of the above materials can be used as a heat insulator, which you can purchase in our store, with all related products (OSB, Isoplat, support beams, vapor barrier membranes, bitumen shingles, etc.).

If you have any questions, our specialists will advise you and help you understand the huge selection of components, and also offer the right type of insulation at an affordable and comfortable price for you.
