Ventilation refers to the ventilation of the linings, unlike the closed air layers. The air must naturally flow between the lining, the wall and the roof. The ventilation is done individually for each house, according to your own project. There are several options for venting solutions. How it will be dealt with depends on the type of building, its location, the number of floors and apartments in the house. It is also important to know the type and leakage of existing wiring, thermal insulation, and whether windows have been replaced.
