What Is Foil Bubble Insulation?
EcoFoil® Double Bubble (Foil/Foil) Insulation consists
of two layers of 8 mil poly bubble insulation which is then covered on both sides by a highly reflective metalized/aluminum composition. It provides an
effective vapor barrier and also provides superior protection against radiant heat transfer.
