Manufacturer for Metal Roof Over Purlins No Vapor Barrier - Vapor Barrier Confusion with air barrier – JiBao

Jibao gas barrier membrane is waterproof, moisture-proof, anti-permeation, and insulates the passage of water vapor.

Performance application: 1. Lay on the foundation layer to enhance the water tightness of the building while preventing indoor moisture from penetrating into the insulation layer, protecting the insulation layer from corrosion. 2. Used in conjunction with the waterproof and breathable membrane on the thermal insulation layer, it can make the wall or roof obtain an excellent water vapor insulation effect, and allow the water vapor in the enclosure to be smoothly discharged through the waterproof and breathable membrane to protect the thermal performance of the enclosure structure. To achieve the purpose of energy saving.

The waterproof air barrier film has good waterproof performance, effectively blocking wind and rain and indoor invasion, effectively blocking the intrusion of cold air, and has the function of heat preservation and energy saving. Used in conjunction with other thermal insulation materials, it can effectively block the intrusion of water vapor into the thermal insulation layer, form a comprehensive protection for the thermal insulation layer, and ensure the effectiveness of the thermal insulation layer, thereby achieving the effect of continuous energy saving and improving the durability of the building.

The vapor barrier film has the functions of impermeability, water resistance, and moisture resistance. The vapor barrier film is laid between the roof base and the insulation layer, which can enhance the air-tightness and water-tightness of the building, and slow down the discharge of water vapor and indoor moisture in the concrete structure to the insulation layer. When the vapor barrier film is used in conjunction with the waterproof and breathable film on the insulation layer, it can effectively discharge water vapor, protect the thermal performance of the enclosure structure, avoid the breeding of mold on the roof, and improve the air quality of the room. So as to achieve the purpose of saving energy consumption.
