Foil Backing

Foil Backing

Foil Backing is also used to improve heat transfer. More heat is drawn and radiated by binding foil to an outer layer of rubber. achieved by factory bonding silicone or foam rubber to the element or by encasing Fiberglas ® insulation as the outer layer of the heating element. Encasing Fiberglas ® is not recommended for outdoor application since “breathing holes” are used that may allow for moisture absorption.
