Art.No. 51127


SBS-modified bitumen membrane with aluminium composite, glass-fibre reinforcement and anti-slip surface

The innovative surface provides increased UV-protection, mechanical resistance and improved adhesion for the bonding of thermal insulation. It helps also for the visual detection of mechanical damages of the vapour control layer. The red signal stripe marks the membrane as vapour barrier.
