As the main material for self-warming of the attic, as a rule, gypsum plasterboard sheets are used. For fixing drywall, a galvanized profile will be used. It is best to use moisture-resistant type gypsum plasterboard.
First, the starting strips of the frame are laid on drywall, and then wooden blocks are inserted into them, the size of which should correspond to the size of the profile. The bars are fixed with self-tapping screws. In order to save material, it is allowed to stack short bars on top of each other. This approach will not affect the strength of the structure in any way..
Inside the attic, as a rule, plywood or chipboard is used. Their size must also match the size of the profile. However, in chipboard structures, gaps are very often formed, which must subsequently be sealed with polyurethane foam. Insulation material should always be laid on the inside of the chipboard. For insulation, it is best to use adgilin, which is attached with a construction stapler.
The space between the metal profile is filled with mineral wool. Also, during the insulation of the attic, a vapor barrier layer should be arranged. Such a structure, consisting of a combination of different materials, also has excellent sound insulation properties..
