If the veranda is intended not only for relaxation in the warm season, but also in colder time, then it is desirable when it is still designed, insulate the standard design.
The first thing you need to pay attention to is the camps. It is through them that the room loses about half the heat from the house. In addition to heat loss through the walls, it is also lost through the openings of windows and doors. But paying attention to the windows, doors and wall should not forget about the flooring and roof of the veranda, they also need insulation.
When choosing material for insulation, you need to build on the characteristics and condition of the enclosing structures, and also for which the room is intended. Actually, since the premises of the veranda need warmth only some limited time, unlike the main house, then its insulation is less strict. This means that for such rooms, insulation is used one or two times less than for houses or cottages.
Since the veranda is not a dwelling and it is used, from time to time it is used to warm polystyrene slabs 3-5 centimeters for floors and ceiling, for walls the thickness should be 5 – 10 centimeters, it is also possible to use mineral wool plates with a thickness of 5 – 10 centimeters. For an accurate choice, they are repelled from the thickness of the walls, material, which is used and its conditions. Be sure to remember that if they use the veranda in winter, then all the walls in it should have a heater.
