Aluminum Foil Insulation Description

 

Double sided aluminum insulation refers to a type of insulation material that has aluminum foil on both sides. It typically consists of a layer of aluminum foil sandwiched between two layers of substrate material, such as foam or bubble wrap. The aluminum foil on both sides acts as a radiant barrier, reflecting heat and preventing its transfer through radiation. This type of insulation is commonly used in various applications, including walls, roofs, attics, and HVAC ducts, to provide enhanced thermal insulation and energy efficiency. The double sided aluminum insulation helps to reduce heat gain in hot climates and heat loss in cold climates, making it an effective solution for improving the insulation performance of a building or structure.

Double sided aluminum insulation is ideally used as sarking and insulation under roofs, in walls behind cladding or under timber floors, for residential and commercial building. Should be kept clean of dust which may pose some problems, for example, when installed under the roof.

Double sided aluminum insulation needs to combine with other insulation options in colder climates to beat heat loss due to convection. Combining with glass-wool /rockwool/ mineral wool/ foam insulation, aluminum foil insulation is excellent as a vapor barrier for air-conditioning ducts, pipes and vessels.
