This material is used for walls, roofs, ventilation, pipes. In addition to excellent thermal insulation properties, it guarantees good sound insulation characteristics. It can also be used in any building structures.
Before using URSA insulation, technical characteristics, advantages, disadvantages, main types and methods of using the material are evaluated.
Line of professional material
Description and main types of Urs
The basis of Ursa insulation is fiberglass, therefore, in terms of its characteristics, it is most similar to glass wool. It consists of sand, dolomite, soda, and other components. The components are heated and then passed through special equipment, which makes it possible to obtain a fibrous structure with thin filaments.
There are several types of URSA heat insulator. The most popular is GEO insulation, which is made from safe and environmentally friendly components. Other types of insulation are also popular on the building materials market:
- URSA XPS. For its manufacture, a special technology is used that guarantees high performance. It has good thermal insulation properties, plates made of this material serve for many years. URSA XPS is used for finishing roofs, facades, basements, it is able to withstand heavy loads, therefore it is used not only in private, but also in industrial construction.
URSA XPS - PureOne. Mineral insulation of high quality, guarantees a high rate of noise protection. The advantages also include safety, ease of work with the material, the absence of the effect of attracting dust. In addition, the insulation does not irritate the skin.
URSA PureOne - Ursa Terra. Is different high level stiffness and density, used for residential buildings. In terms of indicators, the coefficient of thermal conductivity is close to professional materials.
URSA Terra - URSA GEO. According to its characteristics, the insulation is similar to mineral wool. But at the same time, it contains only natural and environmentally friendly components. Ursa light GEO has a good heat resistance and does not contain harmful components.
URSA GEO Regardless of the type, Ursa heat-insulating wool is a durable and strong heat insulator for internal and external insulation of premises for various purposes.

Characteristics of the Ursa range of thermal insulators High thermal insulation qualities, durability and biological stability make it possible to use it for insulation of roofs, facades, walls, ceilings, floors and even steam baths.
Communication protection Material Advantages
The use of modern URSA insulation has a number of significant advantages:
If high-quality insulation, sound insulation and vapor barrier are required, it is recommended to give preference to the Ursa trademark.
Features of home insulation
When insulating various parts of the house, a material of a certain size and type should be used. First of all, the facade is insulated. To do this, it is better to use URSA GEO mineral wool, after which you can use the exterior finish with siding, natural and artificial stone, brick.
Roof insulation For the roof, you should select the option of insulation based on the type roofing and features of the attic space. For pitched roofs, thermal insulation is laid under the rafters and between them, a superdiffusion membrane must be laid on the outside, and a waterproofing film on the side of the room.
For warming flat roof materials with high strength should be used, so mineral wool does not apply in this case. The best solution would be to use Ursa XPS, which has a high rate of strength and moisture resistance.
Mounting Urs to a frame wall 
Insulation installation The use of high-quality insulation guarantees an optimal microclimate in the room and savings on heating. Installation of Urs is quite simple, so even inexperienced builders can use it.
Today, in most cases, the construction of private houses is made of wood. However, for a comfortable stay in winter period time it is recommended to insulate the building.
Ursa thermal insulation is best suited for the above purposes. You can buy at an affordable price not only heat-insulating blocks, but also special mats.
It is best to install thermal insulation outside the house. In this case, excessive condensation on the surface of the walls can be avoided. To install thermal insulation, you will need the following:
- mats made of special material;
- tools;
- wooden boards.
The technological process and installations allow you to mount insulation inside the house. However, for this it is necessary to use a vapor barrier. The bottom line is to protect the heat insulator from condensation.
After the first row of the crate was completed, and a heater was installed (either glass wool or stone wool), experts strongly recommend installing a second layer of insulation.
This is done in exactly the same way that was not described above. However, installation is carried out perpendicular to the created crate. Such insulation is quite enough for middle lane Russia.
Heat-insulating materials can be covered with cladding. Today, Russian construction markets have the following options: lining, metal siding, pvc siding, etc.
Ultimately, the insulation layer of the house is 100 millimeters. In order to avoid the creation of cold bridges, it is recommended to use heat-insulating tape.
It is applied to all seams of the heat insulator. Between finishing material and the heat insulator should have a gap of 2 cm.
The video demonstrates the installation of a facade insulation system for a house using Ursa insulation. Installers will demonstrate all the steps technological process settings:
High-quality insulation of your home is one of the most important tasks of any homeowner. Of course, with a prudent approach, the owner of the house will strive for high efficiency, while keeping in mind affordable prices for insulation materials, environmental and fire safety of the structure being created. And only a high-quality product of well-known manufacturers can guarantee such a combination.
One of the most popular thermal insulation materials is mineral wool, made from environmentally friendly natural raw materials. If we argue from the standpoint of cost, then the most profitable is the use of mineral wool based on fiberglass. But here, however, you can hear a lot of “negativity” about glass wool - low stability, brittleness, a tendency to stall and loss of volume, getting wet with moisture, etc. Perhaps all this is true if you purchase incomprehensible material from an unknown manufacturer. But everything is completely different when a high-quality Ursa insulation is selected, the technical characteristics of which will be discussed in detail in this publication.
Corporate logo trademark"URSA" cannot be confused with any other - these are the silhouettes of a polar bear with a cub. This is how the word "ursa" is literally translated from Latin. This trademark was officially registered not so long ago - in 2002, however, the history of the production of thermal insulation and building materials of this company is much richer.
The origins should be sought as early as the beginning of the 20th century - in 1907, the Spanish entrepreneur Jose Roviralta decided to organize the production of innovative building materials based on fiber cement. It is interesting that mineral rocks delivered from Russia were originally used as raw materials - from Ural mountains. This circumstance gave the name of the company - "URALITA", which in literal translation means "Ural stones".
The business, as they say, went ahead, began to expand, and pretty soon URALITA products became recognizable and in great demand throughout Europe, and the company itself "stepped over the borders" and turned into a transnational concern.
At the end of the last century, the concern included Pfleiderer and Poliglas, leaders in the production of thermal insulation materials. Then, a logical decision was made to unite all research and production facilities operating in the insulation materials sector under a single brand - and this is how the "polar bear" - "URSA" was born
Nowadays, products under the URSA brand are produced at 14 enterprises located in various European countries. Three powerful factories operate on the territory of Russia - in the city of Chudovo, Novgorod Region, and the city of Serpukhov, Moscow Region.
Interestingly, the plant in Chudovo is the oldest division in the entire structure of the URALITA concern - this enterprise, which previously specialized in the production of glass, dates back to 1876. Now it is a powerful, fully modernized enterprise that meets the most stringent international quality and environmental standards.

URSA product lines
The main volume of products of the URSA brand is mineral wool insulation based on fiberglass, produced according to a special technology developed by the company's specialists, which eliminates or minimizes the characteristic disadvantages of glass wool. However, the range of "URSA" is not limited to this - completely innovative developments of fibrous thermal insulation materials "URSA PUREONE" and heaters based on extruded polystyrene foam "URSA XPS" are on sale. In addition, it is planned to produce special membrane coatings necessary to create efficient systems thermal insulation.
Insulation materials of the URSA GEO line
This is the most common material in the range of the company. It is based on fiberglass, made from purified quartz sand with mineral additives. The special eco-technology of GEO production, the subtleties of which, of course, are a trade secret, makes the products absolutely safe for humans and for environment– the canons of the modern approach to "green building" are observed.
- Although in the production of mineral wool insulation it is not yet possible to do without organic binders, their emission in URSA GEO has been reduced to almost zero, that is, a clean and healthy atmosphere will be maintained in the premises.
- The most important advantage of URSA GEO heaters is incombustibility and resistance to high temperatures. The material not only does not ignite, but also prevents the spread of flame.
- The material has a pronounced biostability - it does not lend itself to debate or decay, does not serve as a nutrient medium for any life forms.
- Convenient forms of release of heaters of the URSA GEO line greatly simplify the installation of thermal insulation structures. Despite the apparent fragility, fiberglass has excellent strength and elasticity. In some cases, the installation of insulation boards or mats will not even require additional fixation.
- Thermal insulation "URSA GEO" stands out against the general background with increased durability - it does not fall off, does not lose shape and performance characteristics, and is capable of serving faithfully for at least 50 years.
The product range of "URSA GEO" includes about 20 items. It makes sense to consider those that are most often used in individual construction.
- URSA GEO M-11
This type of insulation can be safely attributed to the most popular - it is characterized by increased versatility, and is used in almost any area of private construction to create thermal insulation or soundproof structures:
- for insulation of interfloor or attic floors along beams or logs.
- for warming frame walls or creating soundproof interior partitions.
- can be used as a heater in multilayer brick or stone walls.
- great for warming loggias and balconies.
- used for thermal insulation of pipelines or ventilation ducts.
Available in rolls of various lengths and widths - very convenient for self-assembly.
- URSA GEO M-11mini"
Reduced release format - "URSA GEO M-11 mini"
In the practice of private housing construction, there are often areas for which it is more convenient to use small-format material for insulation or sound insulation. The manufacturer thought about this issue - "URSA GEO M-11 mini", being an analogue of the above type in terms of operational parameters, is produced in the form of narrow mats twisted into rolls. This greatly simplifies both the transportation of material by personal transport and the carrying out of independent installation work.
Prices for URSA insulation
- "URSA GEO Private house"
The name of the species speaks for itself - this is a product of increased versatility, designed specifically for use in individual construction or for.
Great for insulating ceilings along beams or logs, for thermal insulation of frame walls, for building internal light partitions with the required level of sound insulation.
The packaging of the material is convenient - it is designed for 20 m², which makes it easier to carry out calculations when planning construction or repair work.
- URSA GEO Light
If the owners are primarily interested in the cost-effectiveness of thermal or sound insulation work, then you can stop at the “lightweight” version of the insulation - “URSA GEO Light”.
Most accessible view insulation - "URSA GEO Light"
This material also has versatility - it can be used in horizontal unloaded insulation structures (floors and ceilings along beams and logs), as well as for acoustic ceilings and interior partitions.
Material of specific purpose - created specifically for the insulation of pitched roof structures. At the same time, it creates reliable thermal insulation of the roof and highly effective protection against the penetration of external noise, which is especially important for attic dwellings.
In the production of this type, a special technology is used - "URSA Spannfilz", which can be translated as "elastic felt". The plates have a pronounced elasticity and perfectly fit between the rafter legs, thereby providing both good fixation and the absence of "cold bridges".
The form of release is also interesting - plates in a roll. This makes it easy to cut material in any direction, minimizing waste at non-standard distances between rafters.
- "URSA GEO Universal Plates"
In some cases, it is more convenient to use not rolled mats, but separate slabs for carrying out ordinary insulation work in a house or apartment. This is also provided in the product line - you can purchase universal plates.
The main purpose of this material is the insulation of wall structures and the creation of soundproof partitions. However, it is not in vain that they are called universal - the plates are quite suitable for thermal insulation of floors, pitched roofs, along logs, balconies and loggias.
The convenient length and width of the plates (600 × 1000 mm) will greatly facilitate their installation in conditions, for example, of a cramped room or a limited working space.
- "URSA GEO Noise Protection"
A special type of material intended primarily for use in the construction of internal frame partitions. It has pronounced noise-absorbing properties (sound absorption class B). A special roll size (width - 610 mm) is designed for installation between the frame guides, located with a standard pitch of 600 mm.
However, such mats can also be used for insulation and soundproofing floors, creating acoustic ceilings.
- "URSA GEO Framework"
The main purpose of this variety is the thermal insulation of structures on a metal or wooden frame. Thickness range - from 100 to 200 mm allows you to effectively insulate the walls during the construction of such popular in our time
Especially for frame structures— «URSA GEO Framework»
Designed mainly for vertical wall structures. The material has a high degree of elasticity (thanks to the already mentioned URSA Spannfilz technology), which ensures the stability of the thermal insulation layer and the absence of "cold bridges". It can also be used as an insulating middle layer for “well laying”, for insulating roofs and ceilings along logs or beams. It can be used to create an insulated ventilated facade, but with the obligatory use of a windproof vapor-permeable membrane.
- "URSA GEO Facade"
Fiberglass-based boards designed exclusively for external wall insulation using the “ventilated facade” technology. They have increased strength and dimensional stability. On the outside, they are pasted over with black fiberglass of high density and strength, which makes it unnecessary to use additional wind protection.
If the facade insulation is planned to be two-layer, then such plates are used for the outer layer.
- "URSA GEO M-11F"
A special kind of insulation mats, specially designed for thermal insulation of rooms with high humidity(for example, baths or saunas).
"URSA GEO M-11F" is a foil material specially designed for baths and saunas
The outer side is covered with aluminum foil. This layer creates a reflective screen that redirects the heat flow towards the room, and at the same time becomes an effective barrier that prevents steam from penetrating into the thickness of the material. Thus, with internal insulation, there is no need to use additional vapor barrier membranes, which greatly simplifies installation.
Scope of application - thermal insulation of walls and ceilings in baths and saunas, but it can also be used in other insulating structures inside the building.
The table below shows the main parameters of the mentioned heaters of the URSA GEO line. Thermal conductivity values are indicated for temperatures of +10 and +25 °C, as well as for normal (mode A) and wet (mode B) conditions of everyday use.

Insulation materials of the URSA TERRA line
A special kind of thermal insulation materials of the URSA brand are heaters of the TERRA line.
A special technology for their production implies the inclusion of additional mineral components in the composition of the quartz melt. The main focus of such changes is to increase the strength and elasticity of the material, its pronounced hydrophobicity. At the same time, it was possible to achieve higher thermal insulation characteristics.
The increased rigidity and elasticity of URSA TERRA heaters, while maintaining their inherent elasticity, simplifies the installation of thermal insulation structures on surfaces of complex geometric shapes or in pronounced irregularities.
Special processing of the material gives it special hydrophobic properties - water drops roll down the surface without penetrating deep into the insulation.
In order to visually highlight the materials of the URSA TERRA line, they are given a special external color - a grayish-greenish color.
The product range is represented by three types of material:
- URSA TERRA 34 PN
The material is produced in the form of plates of a convenient width of 600 mm, which simplifies their installation.
The main scope of application is external insulation of facades along the frame, followed by wall cladding with siding. They can be used for frame walls, for ventilated facade systems with fastening of the finishing cladding on brackets. They are successfully used for brick multi-layer walls, made according to the principle of "well masonry" with an internal insulating layer.
It does not exclude the use for thermal insulation of floors and ceilings along beams or logs, for insulation of a pitched roof with the placement of plates both between the rafters and a continuous layer under them.
Belongs to the category of professional insulation materials.
This is the optimal solution for technical thermal insulation. Due to its elasticity and flexibility, the mat will accept any curved position, while ensuring full adherence to the surface. This quality makes it possible to use such mats for insulation of pipelines of any diameter, ventilation ducts, reservoirs, hydro and heat accumulators, and various technological equipment.
The low mass of the insulation will not have a significant weight load on the pipes or ventilation ducts. Neighboring mats perfectly fit together, without requiring a particularly precise fit.
- "URSA TERRA 34 PN Noise protection"
Elastic and elastic plates of this type are probably the most optimal solution in terms of providing sound insulation during the construction of internal partitions. Their clever width of 610mm is specifically designed to fit snugly between standard frame rails.
"URSA TERRA 34 PN Noise protection" - the best material for internal partitions
The tests carried out show that the installation of URSA TERRA 34 PN Noise Protection boards in an ordinary plasterboard partition on a wooden or metal frame can reduce the level of penetrating noise by two to three times.
Such material is also used for ceilings along logs or beams - both reliable and effective thermal insulation are created at the same time.

Insulation materials of the URSA PUREONE line
The appearance of heaters of the URSA PUREONE series, apparently, literally marks a revolution in the production of mineral fiber thermal insulation materials. Even with an inexperienced eye, one can immediately see how different they are from their “brothers”. It is snow-white mineral wool with very special qualities.
A revolution in mineral wool manufacturing technology – URSA PUREONE
For the production of such materials, natural components are used - quartz sand of the highest degree of purification. But the main "highlight" of this technology is the complete rejection of binders based on formaldehyde resins and phenols, the use of recycled products is completely excluded.
Acrylic is used as a binding fiber in a single mass of the component, which, although it is an organic compound, is known for its absolute neutrality, safety for human and animal health, and environmental friendliness.
By the way, the unique pure snow-white color of URSA PUREONE materials is by no means the result of any coloring, since the natural shade of the quartz melt is just that - bright white. And the acrylic component only retains this natural color.
The environmental safety of insulations based on acrylic binder has been comprehensively tested in accordance with the most stringent international standards. According to the unanimous opinion of experts, URSA PUREONE thermal insulation meets the highest requirements for cleanliness and safety, and therefore is approved for use in children's educational and medical institutions. Naturally, it is perfect for the conditions of a residential building or apartment.
Acrylic processing of quartz fibers gives them a special elasticity. They become much less brittle, that is, the insulation does not “dust”, it is convenient to work with it, since even to the touch it resembles natural cotton fiber and is not capable of causing skin irritation.
The increased elasticity of the fibers is also a big plus for the soundproofing capabilities of the material. In such an elastic medium, sound waves quickly lose their energy, dissipate, and become unable to “shake” the partitions for further sound propagation.
The URSA PUREONE product range is represented by three types of material:
- URSA PUREONE 34 PN
This universal insulation is made in the form of plates, convenient for installation on any building structures. It has excellent thermal insulation properties and the highest noise absorption rates - it belongs to class "A".
The areas of application of such a material are practically unlimited, that is, from the roof from above to the thermal insulation of cold floors along the logs or beams from below, including, of course, the insulation of facade walls from the outside or from the inside, the creation of acoustic ceilings and partitions.
Technical characteristics and scope of this type of insulation are similar to the previous one. The main difference is in the applied “elastic felt” technology, which has already been mentioned above. Such plates are more convenient to install between the guides of the frame structures and between the rafter legs of the roofing system.
There is also a difference in the form of release - these are “plates in a roll” that are convenient in transportation and installation.
- URSA PUREONE 37RN
An equally versatile and highly effective material, but available in long mats.
This form of release is especially in demand for quick installation over large areas or for insulation and sound insulation of curved building structures.

Heaters of the URSA XPS line based on extruded polystyrene foam
In the product range of thermal insulation materials of the trade mark " URSA" there are also heaters designed for the most extreme operating conditions - with increased mechanical stress, high levels of humidity, or even with direct exposure to water.
We are talking about extruded-based insulation - this material is different high rates resistance to heat transfer and, at the same time, pronounced mechanical strength.
In the production process, carbon dioxide is used as a foaming agent - completely harmless to the environment. The addition of special flame retardants to the component composition dramatically increases the fire-fighting characteristics of the material, although, of course, it cannot be completely classified as non-combustible.
Extruded polystyrene foam is characterized by almost zero water absorption, resistance to freeze and thaw cycles, so it is perfect for thermal insulation of the underground part of the foundation and basement walls. It is used to create insulated blind areas around the basement of the building, as it tolerates direct contact with water or vegetation without any problems. The only thing he's really "afraid" of is ultraviolet radiation. But with proper installation and protection from direct sunlight, the durability of the material is estimated at 50 years or more.
Plates "URSA XPS" have verified dimensional parameters, are equipped with special lamellas for joining adjacent elements, which greatly simplifies and speeds up installation.
- URSA XPS N-III
These are universal rigid polystyrene foam boards, which are widely used in all areas of construction.
Used for insulation of flat roofs of any degree of complexity. In the case of pitched roofs, it is possible to place a continuous layer of slabs on top of the truss structure.
In wall structures, they can be used as an insulating layer for “well masonry”. Excellent for creating a thermally insulated plaster facade.
They are widely used for floor insulation on any basis, including - with subsequent pouring of the screed or as a basis for further installation of the system.
They are used for warming socles, shallow foundations, external and internal walls of basements.
Prices for URSA Geo insulation
insulation URSA Geo
Great for warming balconies or loggias in city apartments.
The surface of the slabs is given a special textured unevenness, relief, which facilitates the performance of plastering work on them.
- URSA XPS N-III-G4
Similar to URSA XPS N-III in terms of technical characteristics of the board, but presented in a wider range of thicknesses. The price for them is somewhat less, since due to the reduction in the content of flame retardant additives, the flammability class is also lowered to G4. In this regard, the recommended application is basements, foundations, plastered facades, floors with subsequent pouring of the screed.
- URSA XPS N-V
This type of slab belongs to the category of the most durable, capable of withstanding extremely high loads, which, in principle, determines the specific scope of application.
They are used to insulate deep-seated foundations, floors in rooms where high loads are expected (for example, production workshops), flat exploited roofs, roads and railways, airfield runways. In private construction, the use of such heaters looks clearly redundant.

Branded membranes of the URSA SECO line
The creation of insulating structures on walls and roofs very often involves the mandatory use of special film coatings, with a different "mechanism" of action, depending on the location. In the range "URSA" this moment is provided:
- « URSASECOA"- it is a vapor-permeable diffuse membrane, which is used to protect mineral wool insulation from the effects of wind and direct moisture, but does not prevent the free release of water vapor into the atmosphere.
- URSA SECO AM- a membrane similar in purpose, but due to a special three-layer structure, it has higher strength characteristics, vapor diffusion and water resistance. It can even be used as a temporary roofing sheet for up to 2 months.
- « URSASECO B»- a vapor barrier film that protects the insulation layer from direct moisture and water vapor saturation. Placed on top of the insulation layer indoors.
- « URSASECOD"- high-strength hydro and vapor barrier film, the main application of which is the installation of reliable under-roof waterproofing. It has good UV resistance and can therefore be used as a temporary roof for up to 2 months. The material is able to withstand very significant loads during the installation of the roofing system and during its operation.
The main parameters of "URSA SECO" are given in the table:
| SECO A | SECO AM | SECO B | SECO D | |

So, the main assortment of heaters and related materials of the URSA brand, used in private construction, was presented. The tables and description will help you choose the best option, and all that remains is to decide on the thickness of the insulation layer. In this matter, the reader will also be provided with the necessary assistance.
How to determine the required thickness of insulation?
There is a fairly simple calculation algorithm. Its essence is set out in a special publication of our portal dedicated to the main ones. There is also a handy calculator that will simplify independent calculations.
The traditions of wooden housing construction in Russia are rooted in the distant past. To this day, most of the country's inhabitants choose wood as the main building material for their summer cottages. Now, along with log buildings, “Finnish” houses made of timber are very sympathetic. By virtue of low price and ease of use, the most popular on the market has become a bar with a section of 150 × 150 mm. This material is used to build beautiful country houses in which it is great to live in the summer. However, once at the dacha in winter, the owners hardly warm the building, and the accumulated heat very quickly leaves through the thin walls. And then the question of warming the house quite logically arises.
It is best to take care of the thermal insulation of the outer walls even at the stage of building a house, then you will not have to solve a difficult dilemma: which side to insulate the building - from the inside or the outside. There are two options for warming the house, however, experts definitely recommend arranging thermal insulation from the outside of the building. There are several reasons: firstly, you will save internal space. Secondly, the load-bearing wall will be less exposed to sudden temperature changes, which will make the house more durable. Thirdly, in this way the basic design principle will be observed: wet steam, penetrating from the room into the wall, will freely go outside and ventilate. And finally, in a wooden house, a person, as a rule, wants to enjoy the special texture and smell of natural wood - this is possible when the walls are insulated from the outside.
For external thermal insulation of walls, URSA M-15 staple fiber mats or URSA P-15 or URSA Universal plates are used. First of all, you need to install a frame for laying insulation. Wooden bars 50 × 50 mm are vertically nailed to the wall with a distance of 580 mm between them. Such dimensions are due to the width and thickness of the insulation - 600 mm and 50 mm, respectively. If you use mats with a width of 1200 mm, they need to be cut in half - you will get strips of the required width. Mats or slabs are tightly laid in the frame so that there are no gaps between the insulation, the wall and the bars. Now you can proceed to the frame for the second layer of thermal insulation. The bars are nailed with the same step, but across the wall, perpendicular to the first row of the frame. The formed "honeycombs" are filled according to the already known scheme. The total thickness of the insulation, therefore, will be 100 mm - this is enough to protect the house from frost, for example, in Central Russia. At the final stage of work, the house is sheathed with siding, clapboard or facade panels. Between the finishing and heat-insulating material, it is necessary to leave a small (2-5 cm) gap for ventilation.
In the event that the device of external thermal insulation is impossible for some reason, the insulation of the house will have to be carried out from the inside. For this purpose, it is recommended to use URSA XPS extruded polystyrene boards with a thickness of 50 or 80 mm. The boards are attached close to the wall with an adhesive (eg Tytan Styro or Atlas). For vapor barrier, all joints and junctions of URSA XPS boards are glued with a special vapor barrier tape. Finishing can be anything: from wallpaper to plaster. The plaster is applied to pre-sanded URSA XPS boards. Wallpaper is glued on top of drywall sheets, which, in turn, are mounted on a frame of wooden bars installed along the insulation boards.
In addition to extruded polystyrene foam, fiberglass can also be used for internal insulation of the house. The thermal insulation device takes place according to the same scheme as with external insulation: two rows of a frame filled with fiberglass. However, in this case, do not forget to provide another layer in the structure - vapor barrier, which will protect the insulation from wet steam. The vapor barrier film is stretched over the insulation, individual film sheets are joined with an overlap of 100 mm, and all joints and junctions are glued with vapor barrier tape.
Any of the proposed methods of thermal insulation will help make a house made of timber truly warm and cozy even in severe winter frosts, and summer cottage will turn into a cottage for year-round use.

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 above question is unequivocal - internal insulation carried out only in cases of emergency.
So, if you decide to insulate the house from the outside with your own hands, you will need dry thermal insulation material in the form of plates or mats. 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 house frame house, then this way 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:
- first of all, you need to prepare the facade for work - dismantle all the elements that will interfere with the installation of insulation;
- then you need to dilute the glue with water according to the instructions on the package;
- 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);
- 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;
- according to the same scheme, slopes are pasted over, the only thing is that they are not fixed with dowels;
- after that, the evenness of the walls should be checked by the rule, if necessary, individual sections can be rubbed with a grater;
- after that, perforated aluminum corners are glued to all external corners;
- then the hats of the self-tapping screws are smeared with glue;
- 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;
- 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;
- when the glue dries, the surface is treated with a primer using paint roller. The composition is applied in two passes;
- 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;
- 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 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 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:
- 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;
- then a heater is laid between the racks and fixed with dowels;
- 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;
- 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, gas silicate block more durable than arbolite, but at the same time it is more heat-conducting.
Certainly, an important factor The choice is still the price of the material. 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 faced with wood Vacation home, after several rows, pins are laid in the facing wall, which are pre-hammered into 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.
