Are you planning to reduce heating costs due to proper thermal insulation, but do not yet know what is the best way to insulate the house from the outside and how to choose an affordable material with excellent characteristics? Below we will consider the most popular options for insulation for the exterior walls of a house, suitable for thermal insulation of buildings made of wood, brick, and even foam blocks. But first, a little about the advantages of thermal insulation.

External insulation of the house - what is it for?

Scientific studies regarding the analysis of heat losses during the operation of the house have shown that they are about 40%, and in some cases even more. Already only this argument can be considered sufficient to think about the insulation of the house. Of course, thermal insulation is the cost of materials and work on its implementation, but already in the first heating season they will justify themselves.

External insulation is better than internal insulation for several reasons:

• there will be no need to sacrifice the area of ​​\u200b\u200bthe room, which will decrease significantly when installing internal thermal insulation;
• the heat-insulating layer will not accumulate condensate;
• heat loss will be minimal;
• sound insulation performance will improve.

It should be understood that in winter, the house is susceptible to frost, so condensation inevitably forms in the insulation inside it. The material becomes damp, resulting in the formation of mold and fungi. Moreover, wet heaters cope worse with the functions assigned to them. During the summer, the insulation dries out, but not completely, which results in premature wear of the facade walls.

As a result of external insulation, the house is protected from frost, so the moisture that enters the thermal insulation layer is quickly removed to the outside, which allows you to keep the walls dry and extend their service life.

External insulation reduces the level of external noise, contributing to the creation of the most comfortable environment for staying in the house.

As for the shortcomings, only one can be distinguished from the insulation from the outside - these are the costs of materials and installation work. Of course, you can save on paying for the services of workers and carry out thermal insulation with your own hands, but only if the installation rules are followed, which will guarantee the durability and functionality of the thermal insulation system.

Types of insulation for the facade of the house

The market of materials for thermal insulation of the walls of the house from the outside is represented by:

More often than others, due to convenience and practicality, it is used precisely mineral wool. Material is different high thermal insulation, fireproof. In addition, mineral wool retains its original properties when exposed to temperature changes, is not susceptible to moisture and damage caused by insect attacks. For the manufacture of mineral wool, waste from blast furnaces and mineral fibers are used. You can choose for yourself a convenient material option - in rolls or plates.

glass wool- a kind of mineral wool, practically indistinguishable from it in properties. Just like the previous material, it is made on the basis of waste, only this time, generated during the glass production process.

When using glass wool, it is important to reliably protect hands and eyes with a mask and gloves.

Distinctive feature polystyrene foam is a porous structure. It is she who is responsible for the excellent thermal insulation qualities of the material. Expanded polystyrene plates consist of mini cells with air, which prevent the material from rotting and do not absorb moisture. You can insulate the house from the outside with polystyrene foam with your own hands - the process is simple, fast, does not require skill and experience.

An interesting option for insulating the walls of a house from the outside is fiberglass, which is produced on the basis of broken glass, as well as sand, limestone and other components.

The material is produced in plates and rolls. Mounting it is simple and fast. Also, the advantages can be considered environmental friendliness and resistance to moisture.

Not so long ago, ecowool began to be used for thermal insulation. made from cellulose fibres. Features of the material are high rates of thermal protection and resistance to moisture. Ecowool is resistant to fungi and mold, does not attract insects and mice.

How to choose the right material for thermal insulation?

Most often, the owners decide to insulate the house from the outside with polystyrene foam, believing that this material will better cope with the role of external insulation. The decision in most cases is dictated by the low cost of the material, which is several times cheaper than mineral wool and its analogues. In addition, as mentioned above, you can insulate the facade of the house with polystyrene foam with your own hands, saving on paying for the services of craftsmen.

In order to achieve optimal thermal insulation of the facade of the building, sheets with a thickness of 5 to 10 cm can be used.

The finished foam-insulated house is additionally lined using modern finishing materials, ranging from cement plaster to panels with imitation of stone, brick or wood.

The only type of material for which polystyrene foam is not suitable for insulation outside is wood.

Firstly, for natural wood, such a heater is not vapor-permeable enough, and secondly, it is too combustible. Not the most suitable option using expanded polystyrene is also considered in the case of a ventilated facade device due to the need for precise fitting during installation. The average service life of polystyrene as a heater is 25 years.

Ecowool

Mineral wool in addition to excellent thermal insulation, it is responsible for improved sound insulation, which is why it would be advisable to use it for warming houses in the city. But basalt wool is considered the most suitable for insulating the outer walls of city houses. Mice will not damage it, it copes well with mechanical stress and will last at least 50 years.

Glass wool for insulation today is not the most suitable option, despite the excellent performance of thermal protection and affordable price. The main reason for the low popularity of insulation is the complex installation and fragility of the material. In addition, the components that are hazardous to health repel people.

The best option for thermal insulation is ecowool material that is fashionable today. It is better to use it for warming private houses and cottages, a heater is also suitable for thermal insulation of industrial buildings, warehouses, factories. The material perfectly copes with the insulation of the house, does not burn, is resistant to moisture.

Alternative insulation - varieties of materials

For those who are not accustomed to following the standard path, alternative insulation options have been developed for the house outside. These include:

• warm plaster;
• liquid foam.

liquid foam

Liquid foam is prepared before insulating the house on site using special equipment. After being applied to the outside of the house, it forms a practical and reliable thermal insulation. If penoizol cannot be applied to the base in a uniform layer, then you can try to arrange voids on the wall, arranged in a checkerboard pattern, and then fill them with liquid material. Such insulation is expensive, but believe me, after a few seasons, savings on heating will justify the costs.

Using warm plaster as a material for thermal insulation is a profitable and convenient option, given that it will turn out not only to insulate the building, but also to work on creating its exclusive appearance. To insulate materials, it is not necessary to bring the walls to an ideal state with the help of putty mixtures.

How to properly install insulation on the facade?

Thermal insulation can be of two types: bonded and hinged. Bonded thermal insulation is very popular, which is cheaper and more economical than hinged insulation, in addition, it allows you to significantly reduce heat consumption during the operation of the house. Materials for bonded thermal insulation are used light and easy to install, therefore they are suitable for thermal insulation of any type of base.

Before warming, the house is cleaned, leveled as much as possible with the help of special mixtures. Materials for insulation are coated with glue, after which they are firmly pressed into the wall. For greater effect, the plates are fixed with facade dowels. In order for the structure to serve as much as possible, a reinforcing mesh is used, which is also attached to the heaters with glue. The final layer can be a plaster mixture or paint. As an option, siding is also suitable - durable, lightweight with imitation of various natural materials.

In conclusion, we note that the thermal insulation of external walls is an excellent way to prevent heat loss, while creating a comfortable and cozy atmosphere in the room, protecting the house from external influences and extending its life.

The better to insulate the house from the outside: useful tips

Variants of heaters for thermal insulation of the most demanded on the market. Features of the most popular heaters. An alternative to traditional outdoor insulation. Features of installation of heaters.

What is the best way to insulate a house from the outside?

“Nature has no bad weather” is sung in one comedy, but you know that in winter, when the thermometer is -20 ° C, you are not laughing. In severe frost, all hope is for central heating. It struggles with the cold, but sometimes frosts win. Residents of old houses are especially affected, because before they did not pay due attention to the insulation of the walls of the house.

Scheme of wall insulation under siding.

To date, there are many construction companies that will help you insulate houses and apartments. They offer interior and exterior insulation with various materials.

The first question that arises is to insulate the wall from the inside or outside?

You can choose any option, but it is more expedient and better to insulate the wall of the house from the outside.

This method has a couple of advantages: firstly, you save the interior space of the room, which is already always lacking. Secondly, you do not have to change the interior of the room, the relief of the walls and wallpaper.

Any additional insulation is better than nothing, but approach the choice of insulation material rationally. You need to take into account all the factors, the features of your home, the price and volume of the material. The market offers several options for insulating the walls of the house from the outside:

• Styrofoam;
• basalt wool;
• expanded polystyrene;
• mineral wool;
• polyurethane foam;
• fiberglass;
• cellulose insulation.

External wall insulation with foam

Glass wool wall insulation.

Styrofoam is popular in wall insulation, as it is inexpensive and does a good job of insulating its function. There are also opponents of polystyrene, who claim that it is harmful and vapor-tight. Due to poor vapor permeability, windows fog up in the apartment, this can be solved with the help of a hood. Make sure that the hoods in the bathroom, toilet and kitchen function well.

Before starting work with foam, close up all cracks in the wall of the house, and then prime it. Make sure that the wall after fixing the foam on it is even. It is better to do the job right once than to go back and redo it again.

External wall insulation with basalt wool

Basalt wool is an excellent and high-quality heat insulator. It is made from natural materials, so it is safe for health. If you have children, you are afraid for their health, then choose basalt wool. This wool strengthens the walls of apartments, private houses, air ducts, boilers, stoves and boilers. This material is not only a heat insulator, it also prevents the penetration of extraneous noise into the room.

Basalt wool is pressed into basalt slabs, which are then used for external insulation of the house wall. This material is not afraid of either water or fire, it retains heat well, and it is also durable. For wall insulation outside the house, choose high-density basalt slabs. The weight of the insulation is large, so the fastenings must be reliable, it is better to entrust this matter to professionals so that the result exceeds expectations.

External wall insulation with polystyrene foam

Scheme of wall insulation with foam.

Expanded polystyrene is more expensive than polystyrene, but retains heat better. The miser pays twice, so think twice before choosing cheaper material. The minus of expanded polystyrene is poor vapor permeability, so mold forms on the walls of the house and an unpleasant smell comes from it. Sometimes mice can live in polystyrene foam. The main advantage of this heater is its lightness, it is convenient to use because of its low weight.

Before you start working with polystyrene foam, you need to make the walls smooth from the outside, repair all cracks and defects. Your task is not a perfectly flat wall, but as close as possible to the ideal, so that the insulation material fits snugly against the outer wall. Start laying the material from the bottom up, the rows should be horizontal and fit snugly against each other and against the walls of the house.

External wall insulation with mineral wool

Mineral wool perfectly insulates walls, passes air well, does not ignite, has waterproof properties, and is environmentally friendly. This material is more expensive than the above heaters. In addition to this drawback, remember that mineral wool is heavy. The weight of this material greatly complicates the work of builders. It is pressed into mats, with which the walls are further insulated from the outside. It is better to use two-layer mineral wool: one layer is soft and the other is hard. You need to install it with the soft side to the wall, and the hard side out. The thickness of the insulation must be at least 10 cm, otherwise the room will not be as warm in winter as we would like.

Mineral wool will save your walls from fungi and mold. In winter, it will warm your house, and in summer it will perfectly keep cool.

External wall insulation with polyurethane foam (PPU)

Polyurethane foam is popular in the construction world, as it has high functionality. They insulate the walls of the house, the foundation of the building and the roof. PPU is a good heat insulator and sound insulator. If you decide to use this material, then get ready for the fact that it will be with you for 25-30 years. PPU is durable, easy to repair, easy to install and transport. He is not afraid of mice and insects, he is perfect for warming wooden walls and any other surfaces.

Exterior wall insulation with fiberglass

For external wall insulation, fiberglass is sold in rolls or mats. Decide first what width you need, based on this, buy the appropriate sizes of fiberglass. Fiberglass is an excellent material, which is recycled glass in filaments under special conditions. The thickness of fiberglass is approximately 5 cm. In order to insulate the house from the outside, it is better to use two layers of fiberglass. One layer will be vertical and the other horizontal. Fiberglass must be laid so that the joints of the first layer overlap with the second layer.

Cellulose insulation (CU)

One of the main positive qualities of cellulose insulation is environmental friendliness. The second thing to note is the relatively low price and availability. CU is suitable for any surface: concrete, wood, metal, brick, etc. Cellulose insulation covers not only the outer walls of houses, but also attics and attics.

TsU differs in the method of application from other heaters. This material is laid or sprayed on the required wall. The advantage of this application is that there are no seams left in the insulation and heat leakage is impossible.

Knowing how you can insulate a house, what insulation materials are, you can easily choose the right option. Analyze all factors and choose the most rational solution. Seek advice from a professional, entrust him with the installation. Any material will contribute to the fact that your room will be warmer in winter. In winter, you will save on heating the apartment. It is better to insulate the walls well once and pay money for it, and then rejoice for many years.

The better to insulate the house from the outside: a description of the materials

What is the best way to insulate the house from the outside, what material is best for your walls? Styrofoam is popular in wall insulation, as it is inexpensive and does a good job of insulating its function.

The better to insulate the house from the outside: choose a heater

Surely the residents of apartment buildings are a little jealous of those who live outside the city in a private building. Own living space, garden, clean air - everyone's dream. Alas, not everything is so simple, because the harsh Russian winters force you to carefully insulate your home to avoid freezing. This implies impressive investments and constant monitoring of the state of the heat-insulating material, from which residents of city houses are exempted.

Warming your home is preferable to using a dozen heaters - you can save money and make your home more comfortable. It is known that there are two ways of thermal insulation of a private building - from the outside and from the inside. Experienced experts recommend using both, but it is primarily worth taking care of external insulation. About what material is best suited for certain houses - further.

Requirements for thermal insulation material

The consumer is not in danger of a long search for good products - the market is saturated with goods from different manufacturers, so you can choose a decent heater in any hardware store. However, before buying, it is necessary to analyze the material in question for its physical and chemical properties. These include:

• thermal conductivity coefficient (characterizes the ability of the insulation to conduct or retain air; the lower the indicator, the better - you do not have to use a thick layer of material);
• moisture absorption coefficient (indicates the ability of the material to absorb water as a percentage by weight; the higher the indicator, the less durable the insulation);
• density (based on the value, you can determine how much the material will make the house heavier);
• resistance to fire (there are 4 classes of flammability; the first one (G1) is most preferable, which stops burning without an open source of fire);
• environmental friendliness (not the most important indicator for consumers, and in vain - to preserve the health of family members, it is worth choosing only natural material from natural components that do not emit impurities into the atmosphere and do not contain synthetic elements);
• durability (the service life of the insulation set by the manufacturer);
• hygroscopicity (the ability to absorb vapor from the air);
• resistance to pests (insects, rodents, birds);
• soundproofing properties;
• ease of installation (insulation should be fixed quickly, with a minimum set of tools; also, a minimum amount of additional work should be done with it, such as cutting into even pieces).

It is difficult to choose a material that would have all the desirable qualities. For this reason, it is possible and necessary to carry out insulation outside and inside.

Advantages of external thermal insulation

The question of insulating a private house from the outside arises in two cases - at the design stage of a building or when buying a finished one, but at the same time not having decent thermal insulation. The second situation is more common. What are the benefits of insulating a home from the outside? These include:

• reduced wall deformability due to additional protection;
• the facade perceives sharp temperature fluctuations; as a result, the service life of the building will be extended;
• freedom in choosing the design of the facade, even when the building is erected;
• the area of ​​​​the interior remains unchanged; this allows you to carry out any kind of decoration, and living conditions will remain the same.

Ways of external insulation of the house

The need and benefits of thermal insulation from the outside are obvious; now the consumer should familiarize himself with the methods of insulation. There are three of these:

• "well" arrangement of the material;
• "wet" insulation with gluing;
• ventilated facade.

In the first case, the insulation is placed inside the walls (for example, between layers of bricks). It turns out that it is "locked" between two levels. The method is effective, but it is impossible to implement it for an already built house.

In the second case, the insulation layer is fixed to the glue on the outside of the walls, then additionally attached to the dowels. Several types of coatings are applied on top - reinforcing, intermediate, decorative (finishing). A good way, only requires the intervention of specialists; Do-it-yourself wet wall insulation is impossible without experience.

The ventilated facade resembles a “well” masonry, only the outer layer is the facing material - drywall, tiles, siding, etc. Additionally, you will have to build a frame system for attaching heat insulator sheets.

The last method is the most popular, common and profitable. It will cost much less than "wet" insulation; in addition, even a beginner will be able to do the work with their own hands. Now the consumer faces the most difficult choice.

Existing materials can be divided into two large groups - organic (of natural origin) and inorganic (obtained using special materials and equipment).

Types and advantages of inorganic heaters

The first place in the list rightfully belongs to the most popular material - mineral wool. It is of three types - stone (basalt), glass and slag. Differing from each other only externally, varieties of mineral wool have the following qualities:

• low coefficient of thermal conductivity (0.03 - 0.045);
• density variations (from 20 to 200 kg/m3);
• excellent soundproofing properties;
• vapor permeability (mineral wool can "breathe");
• fire resistance.

It is not without a number of disadvantages, including:

• attraction for rodents and insectoids;
• deterioration of thermal insulation characteristics by 50% when only 3-5% of the volume is wet;
• never completely dries out.

In general, mineral wool is good, but it is highly undesirable to use it for cladding a house from the outside.

The second known external insulation is foam. Its advantages:

• the heat conductivity coefficient is slightly lower than that of mineral wool (0.03 - 0.037);
• costs less than other heaters;
• easy;
• density from 11 to 40 kg/m3.

• fragility;
• release of toxic substances during fire;
• does not “breathe”, which forces residents to build additional supply and exhaust ventilation;
• when directly wet, it absorbs moisture, becoming unusable.

Extruded polystyrene foam is not inferior in thermal conductivity to mineral wool and polystyrene. In addition, he:

• does not absorb moisture;
• convenient for installation, because it is produced in plates;
• stronger than foam
• almost does not pass air.

• flammable;
• when burned, it releases harmful substances.

There is another type of raw material used for external thermal insulation of the walls of the house - "warm" plasters. They are a mixture of balls (formed by glass, cement and hydrophobic additives). They “breathe”, isolate the room from moisture, do not burn, are not afraid of sunlight, and are easy to repair. Not very common on the market, however, experienced consumers have already appreciated this insulation.

Varieties and benefits of organic materials

For those who want to feel as close to nature as possible, it is recommended to use raw materials from natural ingredients. These include:

• cork heaters - have a thermal insulation coefficient of 0.045 - 0.06; are crushed tree bark, compressed under the influence of hot steam and resin as a binding element; easy to cut, "breathe", do not form mold, non-toxic; today they are increasingly used to insulate walls from the outside);
• cellulose wool (ecowool) - thermal conductivity from 0.032 to 0.038; are crushed cellulose, treated with flame retardants to improve fire-fighting properties; properties resemble cork materials, but absorb liquid better; do not withstand heavy loads and are not suitable for wall cladding;
• hemp - supplied in plates, rolls, mats based on hemp fibers; does not hold the load well, although it is quite dense (20-60 kg / m3);
• straw - an old way of thermal insulation of the walls of the house; breathable material treated with flame retardants to reduce flammability; today it is practically not used;
• algae - an exotic method of sheathing exterior walls; density up to 80 kg / m3, do not burn, do not rot, do not arouse interest in rodents, are resistant to mold and fungus. Best suited for light walls.

Preferred insulation for home cladding

Each material has pros and cons. Based on the information presented above, it is possible to compile a symbolic rating of the highest quality materials for the walls of the house (the first is the most preferred, etc.). It is also worth considering the type of facade design.

For ventilated systems, cotton wool is better suited - mineral, cellulose. When laying wells, give preference to a material that does not allow moisture to pass through. This is extruded polystyrene foam. Plaster wall decoration goes well with insulation, whose density is more than 30 kg / m3. For example, with mineral wool, PPS, polystyrene, any organic material.

For light walls of a wooden house, breathable material is better suited - mineral wool, hemp, ecowool, cork insulation. The former is preferable, but costs a little more.

A country house should be of high quality sheathed with reliable material. The consumer can choose any of the previously discussed, guided by their wishes or financial capabilities. A competent approach to the acquisition of insulation is the key to a long service life of a cozy home.

We warm the house from the outside - the pros and cons of materials

An overview of materials that can be used to insulate a house from the outside. Pros and cons of heat insulators, features of mounting insulation on walls.

How to insulate a house from the outside - the best materials and methods of insulation

To provide your home with warmth in the winter, it is necessary to insulate the entire structure. Materials should be selected in such a way that they do not carry additional load on the house. In this article, we will analyze the better to insulate the house from the outside, what technologies and recommendations should be followed.

Advantages of external thermal insulation

At the time of designing the house, you should consider the insulation of the entire building from the outside. The main advantages of insulation:

• due to additional protection, the deformation of the walls is reduced;
• the facade part tolerates sharp temperature changes well, which increases its service life;
• the area of ​​all interior spaces remains unchanged.

Types of insulation materials

To understand which material is best suited for external thermal insulation, it is necessary to analyze all the advantages and disadvantages of each. The main nuances when choosing products are their thermal conductivity, moisture resistance and vapor conductivity. Modern materials for warming the house outside allow you to perform all the work efficiently and get the desired result. Types of heaters:

• < Пенопласт - материал, состоящий из вспененного полистирола, внутри которого находятся пузырьки воздуха. Выпускают его в виде плит разного размера. По своим характеристикам обладает высокой влагостойкостью и хорошей изоляцией. Недостатком является его уязвимость к солнечным лучам, легко воспламеняется и способен выделять вредные вещества.

Important! For high-quality foam insulation, take care of a good forced ventilation system.

• Mineral wool is a material consisting of fibers. It is produced in the form of rolls or plates. The positive characteristics include: good steam and sound insulation and high resistance to fire. Among the shortcomings, it should be noted that the possibility of absorbing moisture, which leads to a decrease in insulating qualities, also rodents can appear in this material.
• Penoplex is a modern material made of expanded polystyrene. It is produced in the form of plates that have high vapor permeability, are resistant to fire and have low thermal conductivity. Due to the fact that the plates practically absorb little moisture, it can be used under any climatic conditions. Installation does not require the use of special equipment, the plates are perfectly cut with a knife and are easy to mount.
• Polyurethane foam is an ecological material produced in the form of a liquid insulation, which eliminates the formation of cracks. Using this material, bridges can form that can form condensate, from which the walls will begin to dampen. It tolerates frost and is heat resistant.
• Basalt slab - a product made from basalt fibers, it is produced in the form of a rectangular slab. The advantages include: high thermal insulation, the material does not burn, has good sound insulation, is resistant to moisture and high temperatures. It is also worth noting that the basalt slab is not subject to the process of decay and rodents do not start in it. With proper installation of plates, their service life can reach 100 years.

External insulation methods

Experts use several effective methods for high-quality thermal insulation of the house:

• the insulating material is fixed to the front part with building glue, after which the entire plane is plastered;
• three non-ventilated layers are laid on the wall, after which the insulation is fixed to the solution; then leave the airspace and lay the wall in one brick;
• mount the facade together with ventilation, i.e. a layer of insulation is applied to the waterproofing and sheathed with siding or other material.

Such methods are able to maintain and create comfort in winter, as well as significantly save money on energy resources. The reasons for insulation can be different, for example, cracks or a poor heating system. For wall insulation, all work must be done from the outside, because. laying insulation inside the house will block the access of heat to the wall. Lack of wall heat will lead to condensation, moisture, dampness and mold growth. Each of the described methods of home insulation has its own technological features and is produced at different times of the year.

How to prepare exterior walls?

When you already know exactly what material will be used to insulate the building, it is necessary to carry out preparatory work. The stages of preparation consist of the following actions:

• a layer of material is removed from the outer wall;
• level all cracks, crevices or depressions with a mortar;
• clean the wall of debris, excessive dust;
• everything is carefully primed with a deep penetration solution;
• for even laying of the insulation, beacons and plumb lines are set, this will allow you to qualitatively finish the building;
• anchors are fixed to the upper edges of the wall, on which the cord is pulled and lowered, this is necessary to fix the reference point when mounting the frame and heat-insulating material.

All steps should be performed without haste, because. the result will depend on it.

Insulation with mineral wool and foam

To date, the materials in demand are mineral wool and polystyrene. This is due to the fact that they have almost the same laying method, and they also have similar technical characteristics.

Foam application

When using foam, the wall must be thoroughly dried. A dry wall is an important point for external insulation. If the design is dry, we take a sheet of the product and fix it to the plane with glue. In order for the plates to be laid out evenly, it is necessary to fix the finishing bar at the bottom of the wall. As soon as the adhesive is applied to the surface of the plate, it is pressed against the wall. Dowels can be used to firmly fix the plates. The evenness of the laying is checked using the building level and plumb lines. If the first layer is laid out evenly, you can start laying the next one. In the window and door openings, a frame is installed to which the insulation is fixed. Joints and seams are sealed with reinforced tape, after which the entire surface is reinforced with plaster mesh. In the end, the entire surface is primed and plastered.

The use of mineral wool

Mineral wool is a great option for houses made of brick, wood or foam blocks. For high-quality insulation, a rack frame is used. For this, the spreading method is used, i.e. the distance between the slats must be less than the width of the slab. Thus, the insulation will fit tightly between the frame rack. For a wooden house with an uneven surface, two-layer plates are used. A loose layer of insulating material is perfectly attached to an uneven wooden surface.

Expert advice! To obtain a greater effect of insulation with mineral wool, polyethylene should be used.

For cladding, as a rule, siding, decorative brickwork and other building materials are used.

In order to choose the right materials for warming the house outside, carefully study all the information about each type of product, consult with experts or read the forums. In any case, for high-quality cladding of a country house, be guided by your wishes, financial capabilities and the opinion of professionals. Remember, good insulation is the key to long-term operation, warmth and comfort in your home.

The better to insulate the house from the outside: materials for thermal insulation of walls

Types of materials for warming the house outside. Advantages, disadvantages and methods of external insulation. The use of mineral wool and polystyrene for walls. September 7, 2016
Specialization: facade finishing, interior finishing, construction of dachas, garages. The experience of an amateur gardener and horticulturist. He also has experience repairing cars and motorcycles. Hobbies: playing the guitar and much more, for which there is not enough time :)

Warming the house from the outside is, on the one hand, a fairly simple procedure that you can handle on your own, even without any experience. But, on the other hand, this operation raises a lot of questions, moreover, it requires strict adherence to technology, otherwise the result will not meet your expectations. Therefore, below I will describe to you several ways to perform external insulation as efficiently as possible and without damage to the structure.

External insulation methods

Many people who encounter insulation for the first time do not know how best to place the insulation inside or outside. According to SNiP 3.03.01-87, in private houses, for a number of reasons, external thermal insulation should be performed:

• if you place the heat insulator from the inside, the walls will freeze even more than before the insulation. Moreover, a heat insulator will form in the space between the wall and the insulation;
• from the inside it is impossible to provide thermal insulation of the ceiling, as a result of which the insulation is defective;
• internal thermal insulation reduces living space.

Thus, the answer to the question posed above is unequivocal - internal insulation is performed only in cases of emergency.

So, if you decide to insulate the house from the outside with your own hands, you will need dry heat-insulating material in the form of plates or mats for this purpose. As a rule, mineral wool or polystyrene foam is used as a heater. With their help, you can insulate the facade in several ways:

• wet facade- the technology consists in gluing insulation and applying plaster over it. This method is widely used due to its relative cheapness. Its disadvantage is the low strength of the facade and fragility, compared with other finishing methods;

• hinged facade- is a frame to which facade materials are attached (siding, lining, facade, etc.). The insulation is located in the space between the finishing material and the wall. This finish is more durable, but at the same time more expensive;
• cladding with thermal insulation blocks, which can be made of wood concrete, foam concrete, gas silicate, etc. I must say that the thermal insulation properties of these materials are worse than polystyrene foam or, for example, mineral wool. However, they are more durable.

If, for example, you need to insulate an old wooden or country frame house, then this method of insulation is the best solution. Moreover, block insulation can be combined with other heat insulators.

Everyone should decide how and with what to insulate the house from the outside, depending on the situation, financial capabilities and wishes regarding the design of the facade. As you can see, each of these methods has its own advantages and disadvantages.

Below we will consider in more detail all the insulation options described above.

Wet facade

First of all, I will tell you how to properly perform a wet facade. For this you will need the following materials:

• insulation in the form of mats or plates (mineral wool, polystyrene foam or extruded polystyrene foam);
• special dowels for insulation ("fungi");
• glue for insulation;
• perforated aluminum corners
• fiberglass mesh;
• primer;
• decorative plaster;
• dye.

Before buying a heat insulator, people are always interested in - what is the best way to insulate a house from the outside? If the house is brick or made of other non-combustible materials, you can save money and use foam. If the structure is wooden, it is necessary to use mineral wool, which will serve as protection against fire.

The process of installing a heater with your own hands looks like this:

1. first of all, you need to prepare the facade for work - dismantle all the elements that will interfere with the installation of insulation;
2. then you need to dilute the glue with water according to the instructions on the package;
3. then the glue is applied to the surface of the insulation using a notched trowel. If the walls are uneven, you can apply glue with "blunders" in the corners and in the center, which will give more opportunity to align the plates with respect to each other.

It should be noted that at this stage it is necessary to ensure a smooth vertical surface of the walls, therefore, in the process of gluing the insulation, you need to use a level and beacons (a horizontally stretched thread along the wall, along which each row of the heat insulator is aligned);

1. further, the insulation is additionally fixed with dowels. To do this, holes are drilled in the wall directly through the slabs or mats. It is necessary to hammer in the dowels so that they are recessed and do not protrude above the wall surface;

1. according to the same scheme, slopes are pasted over, the only thing is that they are not fixed with dowels;
2. after that, the evenness of the walls should be checked by the rule, if necessary, individual sections can be rubbed with a grater;
3. after that, perforated aluminum corners are glued to all external corners;
4. then the hats of the self-tapping screws are smeared with glue;
5. The next step is to glue the mesh. To do this, use the same glue that is applied with a spatula to the surface of the insulation. A mesh is immediately applied to the treated surface and a spatula is drawn along it, as a result of which it is embedded in the adhesive composition.

I note that the mesh must first be cut into canvases of the required length, taking into account the fact that it should overlap and turn into corners;

1. after drying, the glue is re-applied to the surface of the walls with a thin layer. In order for the composition to lay down evenly, the solution must be made more liquid than for gluing;
2. when the glue dries, the surface is treated with a primer using a paint roller. The composition is applied in two passes;

1. after the soil dries, decorative plaster is applied to the surface and leveled with a small one. When the composition begins to set, the plaster is rubbed with small circular or reciprocating movements;
2. the final step is painting. There is nothing complicated in this procedure - the roller must be dipped in a bath of paint and then treated with a wall. The paint is applied in two layers.

This completes the work. It should be noted that this technology can be used to insulate not only a private house, but also an apartment.

hinged facade

To make a hinged facade on your own is no more difficult than a wet one. To do this, prepare the following materials:

• insulation in the form of mats or plates;
• metal profile or wooden beam for mounting the frame;
• adjustable brackets;
• vapor barrier film;
• dowels for insulation;
• finishing material for the facade.

Many people are sure that the cheaper the heat insulator, the better. However, the same mineral wool or polystyrene can be of different quality. For example, cheap mineral wool can be exposed to moisture, and foam plastic can easily ignite and support combustion, so it is better to use materials from well-known brands, even if they are not the cheapest.

The instructions for warming look like this:

1. after preparing the facade, you must first perform installation. There are quite a few options for its design and location of the insulation in it. Most often, racks are mounted on brackets, between which mats or plates are placed.
   I must say that the installation of the frame is the most critical stage, since the evenness of the walls depends on it. Therefore, all racks must be placed in the same vertical plane;

1. then a heater is laid between the racks and fixed with dowels;
2. then a vapor barrier film is attached over the insulation. As a rule, it is fixed on the frame. To do this, you can use rails that are mounted horizontally, while the film is located between them and the racks;
3. at the end of the work, the frame is sheathed with facade material, after which additional elements are installed - ebbs, corners, etc.

This completes the installation of the hinged facade with your own hands.

Facing with heat-insulating blocks

If you need to insulate an old, for example, log house, then it is better to build additional walls for it, which will also serve as a heater. Of course, this will have to spend more time and effort, but the result fully justifies these costs.

There are quite a few options for cladding walls. The most common materials are:

• blocks of Sibit (it is more correct to say aerated concrete, since Sibit is the name of the enterprise, which the people began to call the material it produces);
• wood concrete blocks - made from wood chips mixed with cement;
• gas silicate blocks - resemble aerated concrete, however, lime is used as the basis for their composition. In addition, this material is obtained by autoclave;
• from polystyrene concrete - contain foam granules in their structure;
• from expanded clay concrete - contain expanded clay granules in their structure.

So that you can decide on the materials yourself and understand, for example, the better a block of gas silicate is in comparison, for example, with aerated concrete, below I will give a table with the main characteristics of these materials:

As we can see, some materials win in strength, others in thermal conductivity. For example, a gas silicate block is more durable than an arbolite block, but at the same time it is more heat-conducting.

Of course, the price of the material is also an important factor in the choice. Arbolite blocks cost about 4,000 rubles per cube, and polystyrene concrete material costs about the same. The price of gas silicate is a little cheaper - about 3,000 rubles per cubic meter.

The house cladding technology is as follows:

• around the perimeter of the house is a shallow foundation. On our portal you can find detailed information about the arrangement of such a foundation;
• then the foundation is waterproofed with several layers of roofing material;
• further along the perimeter of the house a wall is being erected. Since the blocks are large, laying is much easier than brick. However, in any case, it is necessary to ensure that they lie flat and in the same plane, therefore, in the process of work, it is necessary to use the level, plumb lines and beacons;

• if a wooden country house is faced, after several rows, pins are laid in the facing wall, which are pre-hammered into the wooden wall. The pitch of the pins should be about a meter and a half.

Walls built from heat-insulating blocks need further finishing, for example, plastering. Therefore, this technology of insulation is rarely used. Most often it is used in cases where it is necessary to strengthen and insulate a garden house.

If the same procedure is required for a residential building, you can brick it and place mineral mats between the walls. Of course, the costs in this case will be much higher, but additional finishing will not be needed, and the building will acquire a solid and presentable appearance.

Here, in fact, are all the options for external insulation of houses that I wanted to acquaint you with.

Conclusion

As we found out, there are several ways of effective external insulation of houses, which have their own advantages and disadvantages. Regardless of the technology that will be optimal for you, you can cope with this task yourself. The main thing is not to violate the sequence of actions described above and do the work carefully.

For more information, see the video in this article. If during the process of warming you encounter any difficulties or some points are not completely clear to you, ask questions in the comments, and I will be happy to answer you.

For summer residents, owners of private houses, the question of how to insulate the house from the outside and with what remains one of the most relevant. How to properly insulate a house? Competent insulation of external walls not only creates a positive microclimate inside the home, but is very economically beneficial. After all, the need for constant use of heating systems in cold weather is eliminated - therefore, you pay less for electricity. The second aspect is the constant “correct” temperature inside the room, the absence of humidity and, as a result, the exclusion of the appearance of fungus, mold, putrefactive processes.

You can insulate the house from the outside with your own hands using various modern materials. Initially, you need to look at what the walls of the house are made of, and then decide on the choice of insulation. Each insulation has its own fastening technology. External thermal insulation is also good because it does not reduce the volume of the room, does not provoke the accumulation of moisture, and prevents the walls from “sweating”. Consider the most commonly used heaters and the specifics of their installation, ways to insulate the house from the outside.

Foam insulation

To insulate the house from the outside with polystyrene foam is a rational solution. This home insulation is good for everyone: it is light, inexpensive, does not require the use of any special technologies or tools.

Installation steps:

1. First you need to prepare the surface, level it well. Styrofoam is produced in the form of plates, therefore, the smoother the outer part of the wall is, the better the fit (no voids), the less labor costs it will be possible to insulate the house.
2. The surface should be well cleaned, primed to eliminate the remains of glue or whitewash.
3. This is followed by the installation of external window sills (low tides).
4. Installation of the starting bar - the base, which will prevent the foam plates from sliding down. Also, this element helps to lay the plates evenly (observe the line).
5. To insulate the house, the laying of foam insulation begins from the bottom of the wall, the accuracy of the installation of the bottom plate is responsible for the evenness of all subsequent rows. For fixing plates, universal adhesive for facade work, silicone sealant, tile adhesive, and other varieties are suitable. Some craftsmen recommend fixing the plates with nails for greater reliability (3 days after installation). However, in this case, one should take into account the characteristics of the material from which the walls of the building were erected, whether it will be possible to use nails in this case.

As for houses made of timber, before insulating a wooden house from the outside, scrupulously examine the surface for holes and cracks, and then seal them with mineral wool, polyurethane foam or ecowool. There should be no drafts or air pockets.

Before proceeding to describe the characteristics of another insulation, it is worth clarifying some of the nuances regarding the foam. To the frequently asked question: is it possible for them to insulate the house from the outside, the answer will be positive - yes, you can.

It is characterized by fairly good thermal insulation parameters, but at the same time there is an opinion that it is short-lived, has high flammability, and is unsafe in terms of ecology.

Let's look at these factors in more detail:

1. Styrofoam contains polymer additives that are really flammable. However, the danger can only threaten when the installation of the plates was carried out incorrectly, the safety requirements and the rules for operating this particular material were not observed. It is quite successfully used at different stages of building houses, if all stages of the insulation "pie" are correctly carried out, then everything will be fine. Its ignition temperature is 491 degrees, which is almost twice as high as that of wood or paper-based materials. Thus, in terms of flammability, it is no more dangerous than wooden furniture or floors.
2. It is difficult to voice an objective opinion regarding the durability of foam plastic, for the reason that it is relatively young. When choosing, pay attention to its manufacturer, as well as its quality. Most manufacturers guarantee its service life as a heater up to 70 years, taking into account temperature fluctuations from -40 to +40 ° C.
3. Styrofoam is non-toxic, non-toxic, biologically neutral. There has not yet been a single case of a builder or a person who constantly works with him, poisoned or fell ill. When in contact with it, you do not need to wear respirators or protective gloves. It is distinguished by the effect of "breathing" - this allows you to maintain an acceptable level of humidity indoors.
4. On forums devoted to construction topics, sometimes there is information that foam insulation does not provide heat gain. This opinion is correct, but we should not forget that it perfectly retains heat in the house. If you decide to insulate the walls with it, then approximately 30% of the heat that used to "leave" the street will remain indoors. It is very important, before you insulate the walls outside in a private house with foam plastic or polystyrene foam, to determine its thickness, which is required specifically for your home.

Comparative characteristics of materials for insulation

Very often you can hear the question, what is the difference between foam plastic and foam plastic? These heat-insulating materials are really almost the same: both are light in weight, moisture resistant, do not rot, are afraid of solvents, acetone. Both have a "related" origin - a method of foaming polystyrene. In appearance, their difference lies in a different color - the penoplex has a yellow-orange color. But when the question arises, what is the best way to insulate the walls of the house from the outside with foam plastic or foam plastic, the latter demonstrates higher rates of density, moisture resistance, and airtightness.

If you live in a zone of high humidity, then when choosing a heater for external walls, it is better to opt for foam. The same mineral wool in such conditions is completely unsuitable for insulating walls and foundations.

A short list of characteristics of penoplex:

• higher density, respectively, slightly reduced thermal insulation performance;
• higher moisture resistance;
• higher degree of flammability;
• treated with flame retardants, which affects its environmental friendliness.

In turn, foam:

• lower density (brittle);
• higher heat preservation (due to the friability of the structure);
• the degree of moisture resistance is lower (again, due to friability);
• low soundproofing performance;
• performs better in combination with other more durable building materials.

Otherwise, they are almost the same, the choice is yours how to insulate.

Now let's look at what is the best way to insulate the house from the outside, with foam plastic or mineral wool? Again, the choice is always determined by many factors: price, climatic conditions, the material from which the house was built. For example, mineral wool (stone wool, glass wool) is optimal for a wooden house, it is a non-combustible building material. When working with mineral wool, wear protective clothing, gloves, and a respirator.

If we consider the characteristics of both heaters from manufacturers, then approximately the same thermal conductivity parameters will be indicated. In fact, this is not entirely true - the foam during insulation shows the best results. Only dense balsalt wool in slabs can be compared with it - one of the varieties of mineral wool. In terms of ease of installation, foam insulation also wins: no protection when working with the material, low weight, no dust during processing. Plus, insulating with foam is cheaper than with mineral wool in terms of cost.

Mineral wool performs better at the joints, cold bridges are practically excluded, while polystyrene sins with this. The problem is solved if, for individual stages of work, sheets with an L-shaped edge are selected. How to insulate the walls of the house from the outside if they have an uneven surface? Mineral wool is good because it can be cut into fragments of any shape and size - this is very convenient when insulating uneven walls. For foam insulation, the surface must be flat.

Sometimes they are used together, this technique is called multi-layer thermal insulation. In such cases, the foam should be located under the mineral wool. Mineral wool should act as the top layer.

How to insulate a block house from the outside?

Some modern building materials used for the construction of houses initially have high thermal insulation performance. Often, the manufacturer assures that a house built from this material will not need additional insulation. This is not always the case, take, for example, aerated concrete - an excellent environmentally friendly building material with a cellular structure. It really has high rates of thermal insulation, but it also needs insulation.

How to insulate an aerated concrete house from the outside? Due to the high vapor permeability, foam or foam plastic should be immediately excluded. In case of violation of air exchange between the interior and the external environment, condensate collects on the border of the wall and the heat-insulating material (which is why it is constantly wet). If aerated concrete gets wet, mold, fungi will start on it, putrefactive processes will begin. In this situation, polyurethane foam or mineral wool in the form of mats will be appropriate as a heater.

Initially, the surface of the wall is cleaned of debris, then primed. Any irregularities are plastered with a special mixture.

Installation steps:

1. Mineral wool in mats is attached to the treated surface with suitable adhesive mixtures, but in no case with dowels.
2. Fiberglass is laid on top (silicate glue to help), it acts as a reinforcing layer.
3. To insulate those places where window or door openings are located, the insulation material is mounted with a reinforcing mesh or corners.
4. Then follows the turn of plastering and finishing, for example, painting.

The presence of high-quality waterproofing is extremely important for walls made of aerated concrete, since the porous structure actively absorbs moisture. When insulating such a house, dowels and self-tapping screws should be excluded, since any slightest cracks or cracks can lead to disastrous results for the entire structure. Suitable adhesive mixtures or chemical anchors may be used.

How to insulate a house from a bar outside?

Now let's look at how to insulate a house from a wooden beam 150 × 150 from the outside. In theory, foam or foam plastic could also be used here, but there is one “but” - they are not suitable for wooden houses due to ventilation requirements. Mineral wool passes air well and at the same time is thermal insulation. In turn, the foam is a reliable barrier to cold, but does not allow free air exchange, which is important for timber houses. If wooden walls are insulated with them, then after a while fungus and rot will appear on them, especially since in winter there will be nowhere to go from condensate.

In addition to mineral wool, waterproofing, a construction stapler, self-tapping screws with anchors, and a protective antifungal agent will be required, which will need to be pre-treated with the surface of the walls.

The installation steps are as follows:

• wall preparation;
• laying the first waterproofing layer;
• installation of the crate;
• mineral wool laying;
• installation of the second waterproofing layer;
• how to close the insulation on the wall outside the house? The last step is decorative plaster or siding (or other suitable material).

Mineral wool should be located tightly, without through gaps. At the bottom, near the foundation and at the top, under the roof overhang, air should be left to ensure air circulation and steam removal (so that condensate does not settle on the vapor barrier layer).

basement insulation

What is the best way to insulate the basement of the house from the outside? The basement also takes on atmospheric precipitation, which means that the insulation for it must have reliable waterproof qualities. This part of the house can be insulated with foaming agents, mineral wool, polystyrene foam. Each of them requires an individual approach, installation features. However, the best and easiest to work with is polystyrene - durable, strong, moisture resistant. In all respects, this material is the most advantageous among other heaters.

Before installing polystyrene boards, the surface must be treated with a primer. Fastening is carried out on top of the waterproofing layer, with polyurethane glue or with the help of bitumen-polymer mastic. It is important that the adhesive mixture does not contain solvents - this destroys the material. The thicker the plate you choose, the better the insulation will be.

Any house, no matter what it is built from, needs proper insulation. The answer to the question of how to insulate a house from the outside and with what will depend on many factors: the source material of the building, the atmospheric features of the region, and the cost of the insulation. In any case, it is better to spend money on high-quality insulation outside once than to give heat to the street for years, to heat the house around the clock.

How to properly insulate a house with your own hands: home insulation technology

The purpose of this section is to answer the question: “how to insulate a house?”. That is, the articles below deal with the technologies for insulating the foundation, walls, floor, ceiling, roof, etc. The main thing that is constantly being paid attention to is how to insulate all these structures correctly? Well, with their own hands, without "invited experts."

The considered technologies are suitable not only for the insulation of private houses and summer cottages, but also for apartments; the main thing is to understand the basic principles of insulation, the rest is not important.

House insulation can be carried out according to three schemes, depending on where the insulation is located in the construction “pie”:

• insulation outside the room;
• insulation from inside the room;
• insulation inside the structure (there are claims that this can only be done during new construction or during the reconstruction of an old house, in fact, in some cases, it is possible to insulate a finished house without reworking it ... but more on that in a separate article).

Read about these three insulation schemes in the following articles.

Heat loss in the house, or where does the heat leave the house?

Is it possible to make a house warmer ... without insulating? After all, we are all normal people ... I hope :) So, we understand that it is better not to work than to work. It is better to spend money not on what is needed (or maybe not needed?), but on what is pleasant. In general, conclusions can be drawn by reading the article.

How to properly insulate a house, or the Main rules for insulating a house

In this section, in fact, articles about different technologies for insulating a house. However, I offer you information that you need to know before choosing a technology. And even before choosing a heater. From the observance (or non-observance) of these rules depends on how comfortable it will be to live later in the house.

External wall insulation: wet and dry methods of insulation

In fact, you can keep the heat inside the house in a simpler way than insulating the walls: insulating/replacing windows and doors is easier and cheaper. But it just so happened that I wanted to talk about the walls today, but about the windows later, someday, not soon, maybe ...

This article is about two common ways to insulate exterior walls.

Insulation of a wooden house from the outside with mineral wool or foam

The article is intended for everyone who needs to insulate wooden walls - it doesn’t matter what these walls are: houses, baths, cottages, outbuildings, verandas, etc.

(Again, maybe you just need to plug the gaps between the logs? .. But you know better.)

Do-it-yourself insulation of the walls of the house from the outside

In fact, all the articles on this site are written for those who want to “crank out” some kind of “business” with their own hands. Yes, small forces. But, it should be admitted that the “wet” business of wall insulation is not for everyone and not for every beginner. Although, of course, you can do some of the work yourself - the least time-consuming and not requiring serious qualifications. For other things, hire specialists (well, it's me from my bell tower, because I'm not a plasterer).

But in the way that the article is about, anyone who is able to hold ordinary hand tools in their hands can insulate the walls: a drill, a hammer, a level ...

Thermal insulation of the house by spraying

Well, you can also insulate the walls from the outside. Although there are not only pluses in this method, but also minuses ... however, where are they not? (I'm playing the fool: we all know that there are things that have no minuses at all, but this is not about them).

Wall insulation inside the house: advantages and disadvantages

There are reasons that prevent the house from being insulated from the outside. For example, you need to insulate the walls in an apartment on who knows what floor ... high in a word. Then, willy-nilly, you will be puzzled: how to insulate the wall from the inside of the room? And although I am not a supporter of internal insulation, there is a problem and we have to look for solutions.

Warming the house with thermal panels, or How to turn a hut into a palace?

Modern materials are so good that they allow, having a simple tool and basic skills, to give almost any hut a presentable look. At the same time, it will be difficult to guess from what rubbish of material “it” is slapped.

Ventilation of the attic, attic, roof

Heat in the house is not only the materials of walls, floors, ceilings, the integrity of windows and the absence of gaps in the doors. This is also the absence of excess moisture in the structures. And excess moisture is removed very simply: just a properly arranged ventilation.

Do I need to insulate the foundation of the house? (a little theory)

When you need to insulate the foundation of the house, and when you can do without. And also "what?" And How?" are also important questions. What dangers threaten a well-padded foundation and how can these dangers be overcome? Here is an informative article.

Do-it-yourself insulation of the foundation of a house outside: insulation technologies

In this article, we will consider the technologies for external insulation of the main types of foundations: strip, pile-screw, slab, columnar.

And, by the way, let's answer the question: how is external insulation better than insulation from the inside?

And we will also learn how to insulate the foundation with close groundwater.

Do-it-yourself wooden floor insulation

In theory, the floor temperature should not differ from the air temperature by more than two degrees. I mean, the floor needs to be a couple of degrees cooler. Then it will not harm the health of the residents. But very cold floors (by the way, like very warm ones), on the contrary, are harmful.

If the floor is made of “warm” material - wooden - but very cold (you can’t slap on it barefoot all year round), then it is necessary to insulate.

Do-it-yourself ceiling insulation in a private house

There are two ways to insulate a wooden ceiling. We will talk about them in the article. And also about suitable materials for this. And what is not unimportant - about when you can do without ceiling insulation.

« How to insulate the house from the outside? - this question worries many owners of private buildings. Insulation of any room from the outside creates not only a comfortable microclimate, but also has an economic effect. First of all, the increase in temperature eliminates the need for frequent switching on of additional heating. Secondly, low temperatures promote the development of fungus and mold. For this reason, things, ceilings, walls begin to rot. And again - additional costs.

Thermal insulation outside is done in different ways. However, when choosing a suitable insulation, it is necessary to focus on the material from which the walls are made. Let's look at several options for thermal insulation and types of insulation.

What is the best way to insulate a house from the outside?

2. Prime the surface.

3. Install ebbs (external window sills). Align them horizontally with a level.

4. Place a base that will keep the line and prevent the slab from sliding down.

Start laying foam sheets from the bottom. The evenness of the entire row will depend on how correctly the lowest plate is set. Plates "seat" on the glue. After 3 days, further strengthen them with nails. If the foam is used to insulate a house from a bar, carefully seal all the cracks and holes. You can take any material - polyurethane foam, ecowool or mineral wool. The main thing is that you eliminate drafts and air circulation.

How to insulate a wooden house from the outside

First of all, I would like to draw your attention to the fact that a tree of any species evaporates moisture. That is why during the insulation of external walls, care must be taken to create high-quality ventilation. As a heater, choose basalt wool or glass wool. The second option will cost you less. Before starting work, replace wooden window frames with plastic frames.

Installation begins with the installation of a frame, which is mounted from wooden slats installed vertically. The distance between the rails is equal to the width of the heat-insulating material plate. For fastening, special plastic dowels are used.

How to insulate a log house from the outside

For the construction of a house from a bar, as a rule, a bar with a section of 200 by 200 mm or 150 by 150 mm is used. The technology of construction from this material came to us from the southern countries, so in our country it “gives” its owners with enormous heat losses. However, with skillful hands and desire, you can reduce them to almost zero.

2. Install the foam: attach it to the wall with special adhesive mixtures. Apply the composition, spread evenly over the entire surface. After drying, reinforce the foam with umbrella dowels.

3. Make reinforcement. For this purpose, a plaster mesh made of plastic is suitable, on which a layer of plaster is subsequently applied.

How to insulate the walls of the house from the outside: the best insulation

It is quite difficult to achieve optimal efficiency in energy saving at home, even with an ultra-modern heating system, but without resorting to insulation of external walls. It has been experimentally established that about 30% heat escapes through uninsulated walls. The best way out of this situation is one - this is the insulation of the walls of the house from the outside. Thus, with the help of special materials with a minimum coefficient of thermal conductivity, the protection of walls from external influences is enhanced. Warming from the outside creates a kind of barrier between the damp and cold atmosphere of the street and the microclimate inside the home. However, the success of this process will directly depend on the right insulation.

Types of materials for wall insulation outside

Most often, houses are insulated from the outside with the following types of materials:

Styrofoam- has a low thermal conductivity. 90% air and 10% polymers. Easy to install and pretty cheap.

Mineral wool- a heat-insulating material that is made from metallurgical slags and silicates. Unlike glass wool, working with it is safe.

polyurethane foam- does not require the construction of frame structures. All work is carried out only by professionals, since working with insulation requires certain skills.

Penoplex- a new formula of wall insulation, which retains heat better and more efficiently. It has a finely porous structure due to extrusion. Possesses high heat-insulating characteristics.

They also use thermal insulation, expanded polystyrene, liquid expanded clay materials, cellulose, etc. for insulation. However, these heaters are not used as often as the above. Therefore, we will focus on the consideration of the main insulation for walls.

Mineral wool

Mineral (basalt, stone) wool is a fibrous structure insulation, which is similar to the natural material basalt. This insulation is made from alloys of volcanic rocks at a very high temperature. Such wool is completely fireproof and is not affected by fire.

Mineral wool options

Benefits of mineral wool:

Thermal insulation characteristics are very high due to the porous qualities of the fiber. The material perfectly retains heat, and in summer it does not allow heat into the house.

The soundproofing qualities of basalt wool are high, thanks to the chaotic interweaving of basalt fibers, which delays sound waves.

Long service life. Once you have insulated the walls of your house with mineral wool, you can no longer worry about thermal insulation.

High tightness throughout the entire period of operation.

Mineral wool is an absolutely ecological wall insulation that does not pose a danger to either people or the environment. Installation of mineral wool on the facade and walls takes place in several stages:

Preparing the walls of the house outside.

Laying a layer of a vapor-permeable membrane over the wall.

Fastening wooden slats or profiles to walls.

Laying heat-insulating mats.

Another layer of film is stretched over the insulation.

The device of the ventilating facade of the house outside.

And at the finishing stage, new slopes, window sills and trim elements are installed due to the increase in wall thickness.

The cost of such a house insulation varies from 100 to 400 rubles per m².

Styrofoam is very often used to insulate walls from the outside. After all, its thermal conductivity is lower than that of mineral wool - 0.032-0.038 W/m*K and are slightly inferior to extruded polystyrene foam.

Such a heater has many advantages:

Excellent sound insulation of walls;

Light weight, which does not increase the load on the building;

Simplicity and ease of installation.

Installation of foam on the walls of the house is as follows:

Scheme of installation of foam insulation

Setting the start profile.

Applying adhesive to the insulation.

Sticking foam boards on the walls of the house.

Fixing sheets with dowel fasteners.

Installation of reinforcement elements.

Application of a decorative protective layer on the wall.

Giving texture to the facade.

Mounted foam drawing

The cost of such a heater is available - about 50 rubles per m²

polyurethane foam

This material for insulating the walls of a house from the outside is one of the varieties of plastic. It has a cellular foamy structure and 90% is made up of gaseous matter. The rest of the volume is the walls of the cells.

Sectional polyurethane foam

Thermal insulation and properties of polyurethane foam:

The thermal conductivity of the material lies in the range of 0.018 to 0.035 W / m * K, which is better than that of mineral wool.

Perfectly absorbs noise and delays sounds.

Resistant to aggressive chemicals.

It has low moisture permeability properties.

The service life of polyurethane foam reaches 30 years old. This material is absolutely environmentally friendly.

Insulation of the walls of the house with the help of this heat-insulating material takes place in the following order:

Scheme of insulation with polyurethane foam

Reinforcement to improve thermal insulation.

The cost of polyurethane foam is calculated based on the size of the wall to be insulated. For example, it is necessary to make thermal insulation of the facade up to 50 sq. m. It will cost from 300 rubles per m².

Extruded foam is an innovative development that is designed to save energy.

Advantages of foam insulation:

The lowest thermal conductivity than all of the above materials.

Can withstand heavy loads.

It has a long service life - more than 40 years.

Today, more and more homeowners prefer penolex because of its high performance. How is the process of installing insulation:

Penoplex insulation scheme

Preparatory work on the walls.

Applying glue to insulation boards.

Fastening with dowels.

Finishing outside.

The cost of such material varies from 300 to 400 rubles per m².

Features of installing insulation for the home

It is worth noting that the process of installing any type of insulation may differ depending on what material the house itself is built from. Log walls, for example, do not require an air layer between the layers of thermal insulation and the outer surface of the walls. After warming a house made of wood, a ventilated facade is almost always preferred, which provides air circulation. Sometimes it is lined with boards, clapboard or facade tiles are installed. The insulation of the walls of the house, made of bricks and panel blocks, is carried out according to a similar, standard principle.

Insulation for the walls of the house outside: how to insulate and which is better

It has been experimentally established that about 30% of heat escapes through non-insulated walls. The best way out of this situation is one - this is the insulation of the walls of the house from the outside.

How to insulate the house from the outside and how

In order to improve the heat-saving characteristics and increase the durability of a house made of wood, brick or foam concrete, insulation is often made from the outside according to the principle of a hinged facade or using “wet” technology. In this article, we will figure out how to carry out external insulation of a house and what heat-insulating materials are best used for this.

Overview of insulation materials

Mineral wool

Mineral (stone or glass) wool is the most versatile insulation, which is produced with various densities. For internal insulation, a less dense version of the heat insulator is used, for external arrangement it is more dense, which is able to withstand various negative impacts. In general, mineral wool differs from other types of insulation in its high thermal insulation capacity, durability, incombustibility, and mechanical strength. Its disadvantages are poor resistance to moisture and a rather high cost.

Ecowool refers to environmentally friendly types of insulation with low thermal conductivity, like a mineral wool heat insulator. Ecowool is produced from recycled cellulose raw materials and impregnated with special compounds that prevent the material from igniting and rotting. The only disadvantage of ecowool is a complex technological process of application by spraying, however, this method allows you to evenly fill all the cracks and structural protrusions of the facades, reliably protecting the building from the penetration of cold and moisture into the interior.

Styrofoam

Expanded polystyrene is one of the most popular polymer types of insulation, characterized by durability, almost zero water absorption, excellent heat-saving properties, and ease of installation. Most types of expanded polystyrene boards are impregnated with flame retardants, thus improving its fire resistance. Unlike heaters made from natural components, polystyrene and other types of polymer heat insulators are not susceptible to damage by microorganisms: mold, fungus and moss.

Styrofoam is a heater with a sufficiently high heat-insulating ability, light in weight and easy to install, moisture resistant and inexpensive. The disadvantages of polystyrene include its airtightness, low resistance to mechanical damage and toxicity when ignited. In addition, the foam has a low durability, it is destroyed by elevated temperatures and in contact with chemically aggressive substances that are part of some paint and varnish coatings.

What material to choose

But, along with excellent heat-saving properties, insulating materials of natural origin have increased hygroscopicity - they quickly absorb moisture, retain it in their thickness, and when frost sets in, they freeze and lose their ability to shield the cold.

In order to protect the insulation layer made of natural materials, it is recommended to use vapor barrier and waterproofing membranes that screen moisture and do not interfere with the ventilation of the walls.

Unlike mineral wool and other types of insulation made from natural raw materials, thermal insulation made of foamed polymers practically does not absorb moisture and serves for a long time. If the installation of stone or glass wool is associated with certain difficulties and requires compliance with safety standards, then the installation of foam, polyurethane foam or polystyrene foam can be quickly and easily done by yourself. At the same time, the thermal insulation properties of these materials are slightly worse than mineral wool.

Features of insulation of the walls of the house outside

Wall insulation from the outside is mainly carried out according to the technology of hinged facades, leaving a ventilation gap between the insulation layer and the finishing cladding - this way the walls of the house are more efficiently ventilated.

Stages of warming the house outside when arranging a hinged facade:

• Cleaning and drying, treatment of walls with antiseptic compounds.
• Installation of a vapor barrier film with sealing of the joints of the panels with mounting tape.
• Installation of the frame for the installation of insulation and external cladding.
• Insulation laying, fixing with dish-shaped dowels.
• Installation of a waterproofing, windproof multifunctional membrane.
• Fixing the facade finish on the frame using clamps.

Warming of the facades of the house can also be carried out using the "wet" technology - glue a layer of heat insulator to the outer walls and apply a layer of decorative paint or plaster.

Conclusion

In some regions of Russia, the heat-saving properties of brick, wooden, concrete walls are often not enough to form a comfortable microclimate inside the house. External insulation will create an optimal temperature regime in the interior of the building and significantly save on heating.

To maintain the ability of the walls to pass air, it is recommended to insulate houses with heat insulators made from natural materials. But if the budget allocated for warming the house is limited, then the best solution would be to use polymeric types of thermal insulation: polystyrene foam or polystyrene - besides, these materials are easy to assemble with your own hands.
