Warming of facades
It is known that the greatest losses of heat happen through walls therefore high-quality external warming of a facade of the house allows to save on its heating significantly.
Why outside? All the matter is that though it is much simpler to perform works in the building, internal warming of walls leads to reduction of useful area of rooms, besides at such isolation material of which the house is built, does not get warm and, being exposed to differences of temperatures, begins to collapse. Warming of external walls of the house allows to take out a dew point for their contours that prevents formation of condensate and emergence in the building of a mold and a fungus, at the same time the structure also is reliably protected from aggressive influence of external environment - rainfall, a frost, ultra-violet radiation etc.
