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.
