How to keep warm in the house?
The problem of efficiently preserving the heat of Russian apartments and houses, until a certain time, was not considered at all. In large and small cities and large villages, housing is heated centrally and, therefore, we are not accustomed to worry about excessive heat loss.
The situation changed when suburban construction began to gain popularity in Russia. In a private cottage, the owner himself must solve the problem of heating his house, many buildings are heated not with cheap gas, but with expensive electricity. The question of reducing the cost of heat in the winter is more than relevant for any resident of a country house.
As is known from numerous studies, windows are one of the main heat loss points of most buildings.
