SkyFlex flexible air barrier is designed for use in residential and commercial building applications. The product consists of two layers of aluminum deposited to a layer of woven polyethylene. When exposed to air films or enclosed air spaces in building cavities, SkyFlex’s low-emittance exterior layers reduce radiant heat transfer.
