Output – in the outer insulation wall. Solving this problem, you can go different ways. It all depends on the specific conditions and financial opportunities. One of the most popular methods (effective and However, relatively inexpensive) – the imposition of an additional layer of plaster on the outside of the building. We must bear in mind that the traditional sand-cement plaster have a low vapor permeability capacity. Because of this between the wall and the coating may be collected condensate. The surface of the supporting structure in such an environment will be constantly wet.
As a result, a plaster layer occur periodically during the freezing process and thawing, and – of mold. Sooner or later these factors provoke the detachment of the plaster coating. As dry plaster? To prevent this trouble, use osushivayuschie (also called sanifying) plaster with special additives. The basis of their lime-cement, because in conjunction with cement lime gives a lighter and "soft" plaster. But it is additive composition provides porosity, necessary for non-stop movement of steam and salt accumulation. It is worth mentioning another circumstance: on the insulation of the walls in this case it is not, but raising the temperature a couple of degrees due to plastering, of course, in itself a pleasant fact. If the internal moisture inside the walls dry walled iron screws, fittings – all as new, with no trace of rust, then the problem – internal condensation.
And here their tactics. Condensate formed inside the premises, is directly linked to such a notion as "dew point". If you change the external air temperature in relation to the inner even at normal humidity on the walls of the condensation. The dew point depends on the temperature difference (the walls and the air in the apartment), plus the humidity in the room. This process is clearly known to all on the effect of steamed windows.
