Modern ideas about comfort in the country house and the latest technologies in construction allow you to rebuild the country house so that it can not only rest in it in the summer, but also comfortably live frosty harsh winter. To do this, first of all, it is necessary to improve the roof of the house, which usually performs the function of protecting the premises from precipitation. But, knowing that about 35 percent of heat flows through the roof, it is necessary to carry out work on thermal insulation of the roof using modern technological developments. A modern roof is a multi-layer insulating coating of a house of insulation based on mineral wool, a protective membrane, polyethylene foam, otherwise called a vapor barrier. Mineral water insulation perfectly insulations the roof and practically does not weight it. When assembling the insulation is fastened with an even layer between the rafters. Since the roof and the attic premises of the house are located on the heat and cold of the street, the insulation must be saved from damage with special synthetic fibrous membranes that protect it from wind and water. They are attached from above the insulation. Stripes are laid across the roof slope. Moreover, the upper membrane is laid on the previous membrane with a tolerance of at least 100 millimeters. The membrane is also the heat insulator of the roof.
