How to insulate a wall in the apartment

Unfortunately, the level of insulation in housesSoviet construction is not satisfactory. This not only leads to problems with the heating housing in winter, but also to such trouble, as the appearance of mold and mildew. If the "bloom" the wall will not help or antifungals or repair - sooner or later, the mold will return. The only way to get rid of this scourge is wall insulation. The choice of thermal insulation materials in the construction shelves is large enough. Use can be virtually any of them. It remains only to decide how warm wall a flat - from the inside or outside.

Can I insulate the outside?

Insulate outside walls, of course, is much more efficient than the inside. To find out why this is the case, you need to consider such a thing as a "dew point".

"Dew point" - is the ambient temperature at which airborne water vapor condenses.

In the wall, insulated from the outside, "dew point" oftenIt is either in the entire thickness of the insulation or between the insulating material and the wall, and therefore, the inner surface of the wall always remains dry. If the insulation material is laid from the inside, then with a sharp decrease in temperature "dew point" is located between the wall and insulation, which will inevitably lead to the emergence of the condensate. The surface of the insulation at the same time will remain dry, but the growth of the fungus begins underneath. The result - a damp and musty smell in the apartment.

External wall insulation work including industrial alpinism

In multi-storey buildings for insulation of walls on the outside have to hire a team of industrial climbers, and it is quite expensive.

Another obstacle to the warm and dry walls, oddly enough, may be a housing company. In some cities the partial insulation of facades (wall of one apartment) is prohibited.

Wall insulation from inside the apartment

If the only way for you to become laying thermal insulation materials inside the apartment, you should try to do it right. To begin, select a heater.

Competent selection of materials

Despite the variety of thermal insulationmaterials, the most popular are mineral wool and polystyrene (normal or high density - Epps). Both have both advantages and disadvantages. With a sufficiently low thermal conductivity, the foam could be an ideal insulator, if not for his ability to produce in use harmful chemicals to health. Moreover, this fire-resistant material is insufficient. But foam is not afraid of moisture. But mineral wool does not burn, but with increasing humidity increases its thermal conductivity significantly. And the lifetime of the material is much less than the "competitor" - it caking with time.

Preparing walls for insulation

Whatever material you choose, you first need to carefully prepare the wall. To do this, remove wallpaper and treat the surface with primer. If there are cracks in the wall, "blow out" them with foam.

The technology of mineral wool insulation

Installation provides mineral woolfurther finishing plasterboard walls. Despite the fact that after the laying of the material is completely safe, the work must be carried out in a respirator or mask.

Wall insulation from inside the mineral wool

The inner walls of mineral wool uteplenine

First we need to build a framework of metal profiles for attaching drywall.

Then put the mineral wool and always cover it with moisture vapor barrier film. This is necessary to protect the insulation from moisture. Now you only have to attach the drywall.

The procedure for fixing the foam

Mounting foam or Epps most simple. On the prepared surface with an adhesive for drywall or acrylic fillers need to attach the foam sheets.

Thermal insulation inside the walls

The procedure for fixing the foam

Apply the adhesive should not be at allsurface of the sheet, and only in the corners and in the center. And adjusting the thickness of its layer, it is possible to correct the curvature of the walls. It is advisable to install the sheets in "staggered" manner and after the glue has dried further strengthen their plugs. When papered wall completely, the gap between the sheets to fill sealant or assembly foam. This wall can not sheathe plasterboard, simply it is finished to putty.

Besides the possibility of condensation forming,wall insulation from the inside has one significant drawback - a reduction of usable area. In addition, you'll have all the time to monitor the ventilation space, as if the ventilation system is not in order, or completely absent - regularly ventilate it. So it is necessary to produce such works exclusively in the case where the insulation on the outside is absolutely impossible.
