InfraStop® Insulation consists of two outer layers of aluminum foil that reflect over 94% of radiant heat. Each layer of foil is bonded to a tough layer of polyethylene for strength. Two inner layers of insulating bubbles resist conductive heat flow while a center layer of polyethylene gives InfraStop® high reliability and strength.
