Warming of the facades of apartment buildings: modern ways. Thermal insulation material

Recently, the urgency of the insulation of facades of apartment buildings is increasing. This is due to higher prices for utilities and energy, which explains the need to save money. The problem is that most of the apartment buildings that are currently in operation were built almost 50 years ago, their insulation is not as effective as the owners would like.

Solution of the problem

As the statistics show, the loss of heat through the walls reaches 50% of the total heat loss. This is very important. This indicator depends on the design of the house. So, if we are talking about panel buildings, then heat losses are maximal, and in the case of brick houses this indicator is somewhat less.

But the insulation of facades of apartment buildings is profitable from either side. If property owners use autonomous heating, they can save about 20% of the amount spent on gas consumption. If the apartment is connected to central heating, the average indoor temperature will rise by an average of 4 ° C.

Choosing thermal insulation

Warming of the facades of apartment buildings is usually carried out using one of the materials listed below:

• Styrofoam;
• mineral wool;
• Expanded polystyrene;
• Foam glass.

Each kind of thermal insulation has its pluses and minuses, which causes the urgency of using a certain material in a particular situation. If you want to save, you should use foam. It has a low price, which is why it is most common. It can be used anywhere, the thermal insulation efficiency will be missed. However, the pursuit of cheapness is not always justified. If the walls initially have a normal class of thermal insulation, then the insulation with foam will achieve the desired result. When choosing this material, its density should be taken into account. The higher it is, the less its heat-conducting properties.

Warming of the facades of apartment buildings is often carried out with the help of expanded polystyrene. It is quite inexpensive, and its heat-insulating properties are better, in comparison with polystyrene foam. Among the advantages can be identified light weight, ease of installation, hydrophobicity and long life. Excellent polystyrene foam for facing corner apartments. The material almost does not absorb moisture.

If you plan to carry out the insulation of facades of apartment buildings with the use of expanded polystyrene, you should also take into account its shortcomings. They are expressed in low resistance to fire and lack of sound-isolating abilities. The first quality requires the installation of fire bridges. However, expanded polystyrene is excellent for thermal insulation of walls inside and outside the house.

Is it worth using mineral wool

This material is one of the most effective, but its cost exceeds the price of analogues. For this reason, this material is rarely used for thermal insulation of facades. Among its advantages are fire safety, excellent sound insulation properties and hydrophobicity.

It should be noted and one drawback, which consists in a large weight, as a result of which its installation on the facade is carried out with a large number of fixtures (as the last used dowels).

Application of foam glass

When choosing a thermal insulation material for the insulation of the facade of the apartment building, a foam glass is often considered. It is quite expensive, but if you are not limited in means, then the preference should be given to him, because this insulation has excellent thermal insulation, hydrophobicity and durability.

Foamglass is not a combustible material, mold and fungus can not be formed on its surface, as well as other microorganisms. If you use this thermal insulation material, you will need to purchase a large number of related products:

• Building glue;
• Plaster mixture;
• A primer;
• Reinforcing mesh;
• Facade paints.

For fixing dowels are used, liquid foam is also required for the work . To level the surface, it is necessary to stock up the plaster. For additional waterproofing, a primer is applied to the walls, which allows to increase the quality of the adhesion of the plaster with the paint. To fix the plaster layer, a reinforcing mesh is necessary.

Modern methods of insulation of facades of apartment buildings

Warming of old houses can be carried out according to one of several technologies. It is often used for this foam polystyrene plates. At the first stage the façade is prepared, dry mixtures and necessary materials are purchased. On the next you can proceed to gluing heat insulation sheets on the walls.

Additionally, the canvas can be fastened with plastic dowels. The surface of expanded polystyrene is reinforced with a polymer mesh, after which it is possible to start applying one or two layers of plaster. Expanded polystyrene plates, the price of which is quite acceptable, allow achieving good results. Such gluing of facades is carried out at the stage of erection of buildings.

Technology using mineral wool

The technology described above provides for wet work. As an alternative solution is another method, which is to install a siding with thermal insulation. First, a frame is constructed using a steel profile. For this, dowel-nails, self-tapping screws and suspensions are used.

The next step is the installation of mineral wool on the wall, it will be especially convenient to use basalt fiber slabs . Such a thermal insulation system provides for the installation of a steam-and-gas barrier, which is usually a windproof membrane, which reduces the blowing out of heat from the house. At the final stage, siding is installed.

This technology has several advantages. Among them, it should be noted that there is no need for the master to have special skills for performing plastering and painting works. In addition, if you use high-quality PVC siding, if properly installed, it will be ready to serve for at least half a century.

Conclusion

Quite often recently, patchwork insulation of facades of apartment buildings has been used. It involves point thermal insulation. If you apply siding and mineral wool, then the finishing will not require additional care during the entire service life.

When the warm season comes, it will be enough only to wash the surface of the walls, which then again get an attractive appearance. For insulation can be used and polystyrene plates, the price of which is 1130 rubles. For packing.
