Aluminum Foil Insulation Description

 

Double sided aluminum foil insulation DEC-201A is made from 2 outer layers of pure aluminum foil and 1 layer thicker natural kraft paper. These layers are bonded together with polyethylene and reinforced with 3-way fiberglass scrim. The reflective aluminum foil insulation can helps to maintain a consistent indoor temperature by reducing heat gain or loss through the building envelope. Additionally, it can contribute to reducing energy consumption and lowering heating or cooling costs.

Double sided aluminum foil insulation is ideally used as sarking and insulation under roofs, in walls behind cladding or under timber floors, for residential and commercial building. Combining with glass-wool /rockwool/ mineral wool/ foam insulation, it is excellent as a vapor barrier for air-conditioning ducts, pipes and vessels.
