Heated front for house: types, reviews

In construction, there are two types of thermal insulation of walls: internal and external. At carrying out of those or other works different materials which differ between themselves physical and mechanical properties and structure are used. If you apply a facade insulation, it does not take up space inside the premises of the house, and in fact sometimes the area is very limited. How to understand the variety of rolls and plates that are used today for thermal insulation? In order to understand what material is better to choose for external insulation, it is necessary to familiarize yourself with the basic varieties of modern insulation and their characteristics.

Reviews about mineral wool

Mineral wool is a natural material that has a fibrous structure. It is made of molten rocks, and as its main advantages is the resistance to the effects of biological and chemical reagents, hygroscopicity, as well as high sound and heat insulation ability. Consumers note that the insulation based on mineral wool is resistant to deformations and the effects of fire.

Considering the materials of this group, it is possible to distinguish a facade basalt insulation, the lack of which is only high cost. But on the coefficient of water absorption and high fire resistance, mineral wool plates are the leaders in comparison with other types of thermal insulation.

Consumer feedback on the most popular brands of stone wool products

If you choose a façade insulation, you can pay attention to the widespread today production of "Technonikol", which is manufactured in Russia. According to the buyers, these plates show themselves well in the arrangement of ventilated facades. Their technical characteristics make it possible to use this material for the thermal insulation of walls with an increased degree of convection of air currents.

Consumers advise choosing a facade insulation "Rockwool", if there is a need to equip the hinged structures of ventilated systems with higher rigidity and strength. After all, these are the features of the material based on mineral wool.

Similar products are manufactured by the Finnish company Paroc. Specialists recommend using them in the structures of single-layer and double-layered facades, which provide for the presence of a ventilation gap. Due to the fact that this insulation is made abroad, it is worth a bit higher than domestic analogues. For a square meter you have to pay a price from 880 to 980 rubles. According to private builders, this cost is justified by reliability and quality.

Insulation facade should have an excellent vapor permeability. This characteristic is characteristic of the products of the Russian enterprise Izorok. Among other things, the materials of this manufacturer are durable and have low thermal conductivity.

Reviews about insulation based on fiberglass

Fiberglass is made from waste glass industry, it is characterized by high elasticity, resistance to chemical influences and low hygroscopicity. Users argue that fiberglass has a drawback, which is the instability of the fiber structure and low strength. For this reason, the material is so easily crumbled.

Famous brands of products based on fiberglass

Heater facade can be made on the basis of fiberglass. The production of such products is handled by the French concern Saint-Gobain, which produces material that differs favorably from mineral slabs in weight. This allows you to use a heater for light facades, which do not involve heavy loads. Users most often choose insulation from fiberglass company Ursa. A distinctive feature of these materials is the presence of a coating of fiberglass on the outside. Due to this, when using these insulation materials, there is no need to additionally attach the windproof film.

Reviews about Styrofoam

The facade insulation can be made of expanded polystyrene, which is light enough and is made of foam, polydichlorostyrene, and also polymonochlorostyrene. According to users, such insulation from foam has excellent thermal insulation properties, high hygroscopicity and good strength.

To increase the fire resistance to the ingredients in the manufacturing process, flame retardants are added. But users identify shortcomings, which are expressed in the instability of the sun and chemical solvents. The most popular among the modern buyer brand "Penoplex" and "Extrol", which are produced in the conditions of Russian plants.

Reviews about polyurethane foam

If you need a facade insulation, then you can pay attention to the polyurethane foam, which is represented by heat insulation made of molten plastic, 90% saturated with gas. You can purchase this insulation in the form of liquid substance, which is common when using the method of warming on the principle of "wet facade". Private builders are advised to use liquid polyurethane foam together with thermal insulation from mineral wool or polystyrene foam. Above the latter, a reinforced mesh of fiberglass is laid, and then a layer of plaster is applied. It is just made of acrylic, silicone or polyurethane foam.

This facade insulation for the house, as the buyers claim in their reviews, has an insignificant coefficient of heat conduction. It is characterized by the properties of higher adhesion, compared with other materials, and is resistant to chemical solvents. However, like other types of thermal insulation, polyurethane foam has its drawbacks. One of them is expressed in the fact that during combustion, the material begins to release toxic substances. It is for this reason that a heater is recommended for use in the arrangement of industrial facilities.

The main technical characteristics of different types of thermal insulation

Choosing a heater for facade walls, you should not forget that it will have certain characteristics that affect the microclimate inside the premises. Thus, mineral wool has a density ranging from 80 to 100 kilograms per cubic meter. In fiberglass, this index varies from 11 to 30, whereas for expanded polystyrene and polyurethane foam - from 28 to 38 and from 50 to 70, respectively. The water absorption of the described insulation in the same sequence is: 1.5; 1.5-2; 0.4; 0.2-0.4%.

Before buying, you should pay attention also to the vapor permeability of mineral wool and fiberglass. These indicators for these materials vary from 0.3 to 0.32 and from 0.55 to 0.64 mg / (m · h · Pa), respectively. For expanded polystyrene and polyurethane foam, these parameters are as follows: 0.02-0.07; 0.05 mg / (m · h · Pa). The first two of the listed heaters are not flammable, but the expanded polystyrene and polyurethane foam belong to the classes G3-G4 and G1-G3.

Pay for a square meter of mineral wool will have from 350 to 970 rubles, while fiberglass is cheaper, its cost varies from 40 to 145 rubles. Per square meter. In the middle price category is expanded polystyrene, the price of which ranges from 250 to 320 rubles per square meter, but for the mentioned unit of polyurethane foam, consumers pay from 450 to 600 rubles.

For reference

Above, prices for heat-insulating slabs were mentioned, but if you want to make insulation by the method of applying polyurethane foam using the technology of "wet facade", the price will vary from 150 to 1350 rubles per square meter. The final cost depends on the thickness of the applied layer, which can range from 10 to 100 millimeters.

Characteristics of facade insulation "Technonikol"

"Technonikol" is a facade insulation, which differs insignificant thickness, but provides high sound and heat insulation characteristics. Install this material is extremely simple, since it does not cause allergic reactions, and its weight is small. During operation, it exhibits resistance to high temperatures and stability, as well as the inviolability of external parameters. Low water absorption guarantees the prolongation of the service life of the adjacent materials. Rodents "Technonikol" is not interesting, as microorganisms, as well as cockroaches.
