During the construction of any premises, it is necessary to pay attention to insulation. It is necessary to warm the floor and walls, and this also applies to the roof. This is necessary in order to ensure warm conditions without high energy costs in the frost. You will also have to buy a mattress profitable for the whole family. So that in winter you have to sleep warm. Modern roofs are quite light and this allows the use of various insulation materials. This also contributes to the fact that the walls and the foundation do not experience additional load.
The most popular thermal insulation heaters for the roof are stone cotton wool, glass wool or ecovata. Polostiriol is very rarely used, as it significantly reduces the ventilation characteristics of the roof. A large role is played by such a quality of heater as: vapor permeability. Mineral wool is of the greatest vapor permeability, which, in addition to everything, also fits well into the design of the rafters. It is very important to determine the thickness of thermal insulation, as it will depend on the functionality of the building.
There is another separation of roof methods: into a warm and cold roof. If you plan a cold roof, then only the attic is insulated. The warm roof is similar in technology with that. How you insulate the whole house, it will come out much more.
