Vapor Barrier is an internal Air Leakage Barrier Layer for roofs, walls and floors. And it has functions of air impermeability, waterproof and dampproof. It is made of metallic paint film + PPE film + fiber knitting + plastic film by hot-melt adhesive laminating.
A. Vapor Barrier is laid between base of roofing and insulating layer. It can strengthen the air impermeability and water-tightness of building.
B. Vapor Barrier as part of the internal lining will help to reduce the rate of heat lost by convection through the building fabric.
C. Vapor Barrier will particularly apply to ‘vapour open’ constructions where a breather membrane is specified externally. Thus the roof/wall can both insulate the indoor vapour and drain the internal vapour, so as to protect structural durability and the thermal performance of insulation materials.
