Roof insulation leads several new stages of roof device. In addition to insulation effects, waterproofing and insulation create reliable roof protection systems from premature wear. High -quality roof waterproofing increases the lines of operation. Sanitary norms and rules should also be observed in the process of vapor barrier of the roof of the roof of the building. The process of warming the roof also creates additional protective aspects that contribute to an increase in operational time at home. The use of modern insulation of synthetic materials in the insulation of the house requires to look for methods for protecting insulation from water and moisture.
Despite the fact that modern synthetic heaters have high waterproof properties, the insulation layer of the roof needs additional protection against moisture, which condenses on the internal walls of the roofing material and the surface of the insulation bags.
If you do not remove moisture from heaters, then the insulation bags after some time absorb a sufficient amount of moisture and lose their insulation abilities. Therefore, to protect the insulation packages from moisture, vapor barrier is made, which will protect the insulation from moisture coming from the attic building of the house. For vapor barrier, a vapor barrier polyvinyl chloride film is used, which covers insulation bags.
The canvas of the vapor barrier film is installed in an overlap at least 20cm. To seal the vapor barrier layer at the joints, the vapor barrier film is glued with a double -sided adhesive tape. Sometimes a vapor barrier uses a metallic pale film. When using a film with a metallic spraying between a layer of insulation and a vapor barrier film, a ventilation gap is left at least 10 mm. After covering, a layer of steam -permeable film is covered with black and finishing cladding, which uses plywood, fiberboard or lining plates.
