Vapor barrier film has no vapor permeability, water, moisture, and other functions. Vapor barrier between the roofing membrane laid on the grass roots and the insulation layer, can enhance the building air tightness, water tightness, slowing the speed of the concrete structure and interior moisture vapor to insulation emissions. While supporting the use of breathable waterproof membrane vapor barrier membrane and insulation layer on top, which can effectively discharge vapor to protect the building envelope thermal performance, avoid mildew breeding roof, improving indoor air quality. So as to achieve the purpose of saving energy. Vapor barrier material requires not only waterproof, but also requires isolation of steam penetration, it provides the vapor barrier should be airtight, watertight and good material. According to practice, vapor barrier insulation is burying, in order to improve the ability to resist the grassroots level variant, every paving membrane vapor barrier should adopt an empty shop law. Aluminum foil, aluminized composite nonwovens, woven, pearl, glass fiber, kraft paper, mesh, is a new type of environmentally friendly energy-saving materials, replacing the previous glass wool and foam insulation materials like aluminum wholesale woven film, it has the advantage lies in its composite of aluminum flat smooth surface, high reflectivity, longitudinal and transverse tensile strength, not only blocking conductive heat, and can block the radiant heat, reduce heat loss convection, conduction and radiation , truly cool. Aluminum composite products are widely used in areas such as thermal insulation and construction (business: building and renovation of woven metal, masonry wall pipes, plumbing, etc; residential: commercial and residential roofs, ceilings, walls, floors bracket, attic, basement, storage room, car fire doors; Agriculture: livestock aluminized woven, poultry sheds, warehouses, barns, etc.). Aluminized woven, Weihai Fujingtang (certified), woven Limited provided by Weihai Fujingtang new decorative materials. Weihai Fujingtang New Decoration Material Co., Ltd. (www.whfjt.com) is a professional engaged in "anti-static packaging, composite bubble bags, insulation materials, cable composite tape, cable shielding composite" company. Since its inception, we adhere to the "good faith, sound management" approach, the courage to participate in healthy competition in the market, so that the "Fujingtang" brand has a good reputation.
