How Radiant Barrier Works: Heat Gain/ Loss in Buildings

Aluminum foil is one of the few insulating materials that is not affected by humidity, and consequently, its insulating value remains unchanged from the "bone dry" state to very high humidity conditions. The R Value of a mass type insulation is reduced by over 36% with only a 1-1/2% moisture content, (i.e.: from R13 to R8.3).
