TERMOFOL 90

Designed for effective thermal insulation protection, this 90 g/m² vapour barrier membrane features a reflective layer that effectively reduces water vapour transmission from inside the building into insulation layers (Sd >70 m). Thanks to its thin aluminium layer, it reflects heat radiation, supporting the energy efficiency of the roof structure. It provides up to 3 months of resistance to changing weather conditions. It contributes to the elimination of thermal bridges and improves thermal comfort. Resistant to a wide range of temperatures (-40°C to +80°C), the membrane has a flammability rating of E. Its use is particularly recommended in combination with vapour-tight flashings and insulation kits, which form a coherent roof window protection system.
