Thermobreak®

Thermobreak® is a leading flexible thermal insulation material made from physically (irradiation) cross-linked closed-cell, polyolefin foam, factory bonded to reinforced pure aluminium foil and available with a pressure sensitive adhesive backing. With a lower thermal conductivity than any other flexible foam insulation material, almost zero vapour permeability, and its all-in-one concept, Thermobreak® provides superior energy saving performance, fast and simple installation, and trouble -free operation in a variety of environments.
