China Double Side Aluminum Foil Woven Fabric Film for Attic Roof, Find details about China Aluminium Foil Insulation, Foil Woven Cloth Insulation from Double Side Aluminum Foil Woven Fabric Film for Attic Roof
Aluminum Foil woven fabric Radiant Barrier is a material that is a poor re-reansmitter of radiant energy. By definition, this re-transmission characteristic (emissivity) must be at or below 10%. The emissivity of our Aluminum Foil woven fabric Radiant Barrier is about 5%. Therefore, when a radiant barrier is installed in a residential attic roof, it block about 97% of the radiant energy that is being radiated by the hot Roofing materials. This is a coller attic, resulting in a house that requires less air conditioning usage t maintain confortable inside temperature.
The Aluminum Foil woven fabric Radiant Barrier is a material that reduces the rate of radiant heat transfer across air spaces by use of one or more highly reflective surefaces. Thsi rate of hear transfer can be quantified for a sepcific application by an R-value.
