Main properties and functions of vapor barrier film

The main performance vapour membrane:

Waterproof vapor membrane has a good waterproof performance, can effectively prevent the wind and rain to the indoor invasion, can effectively prevent the cold air invasion, has the effect of protecting the insulation layer energy saving energy consumption. Combined with other insulation materials (glass wool, rock wool), it can effectively prevent water vapor from entering the insulation layer, form a comprehensive protection to the insulation layer, ensure the effectiveness of the insulation layer, so as to achieve the role of continuous energy saving and improve the durability of the building.

Function of vapor barrier film：

Waterproof vapor membrane has the function of impermeability, waterproof and moisture-proof. The waterproof vapor membrane is laid between the roofing base layer and the insulation layer, which can strengthen the air tightness and water tightness of the building, and slow down the rate of water vapor in the concrete structure and the discharge of indoor moisture into the insulation layer.

When the waterproof vapor membrane and waterproof breathable membrane above the insulation layer are used together, they can effectively discharge water vapor, protect the thermal performance of the envelop structure, avoid roofing mold breeding, and improve the air quality of the living room. So as to save energy.

Waterproof the material that separates vapor film not only waterproof, still can isolate the infiltration of steam, when choosing waterproof to separate vapor film, should use airproof, watertight sex is good material. According to the practice, the insulation layer is buried and pressed by the insulation layer.

Waterproof and vapor proof film, waterproof, moisture-proof, impermeable, moisture vapor through isolation.
