Aluminum Foil Insulation Description

 

Double-sided aluminum foil insulation is a type of insulation designed to reflect radiant heat in both directions. The reflective foil layers are made of aluminum and are highly reflective, which helps to reflect radiant heat away from the insulated space. The insulation material in the middle layer provides additional thermal resistance and helps to reduce heat transfer through conduction and convection.

Double-Sided Aluminum Foil Insulation can reduces heat transfer, helping to keep spaces cooler in summer and warmer in winter. The aluminum foil layers can act as a vapor barrier, preventing moisture from penetrating the insulation. It is lightweight, easy to install, and can provide effective insulation in a wide range of applications. It is excellent as radiant barriers, flame retardant and vapor barriers can reduce energy loss costs 5% to 10%.

Double Sided 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 and reflective aluminum foil insulation for air-conditioning ducts, pipes and vessels.
