Powerlon ThermaPerm is a premium thermo-reflective breather membrane engineered to enhance the energy efficiency and moisture management of the building envelope. Designed for use in walls in timber frame structures, this non-woven membrane acts as both a vapour control layer and a breathable insulation support, making it ideal for modern construction.
Powerlon ThermaPerm ensures rapid coverage and ease of installation across large wall and roof areas, including walls in timber frame and profiled metal constructions. Its advanced membrane structure allows controlled transmission of water vapour, enabling the structure to breathe while protecting insulation and internal components from moisture ingress.
Manufactured by ITP, Powerlon ThermaPerm is designed with high tensile strength for long-lasting durability in all climates. Its thermo-reflective surface helps maximise thermal performance, reducing heat loss and contributing to a more sustainable, comfortable indoor environment.
