This extremely tear-resistant roofing membrane is highly reliable, as it impresses with proven longevity. This provides fully-insulated pitched roofs – whether with or without formwork – with long-term protection. The reinforced fabric of the breathable membrane ensures its high tear resistance. It can withstand the toughest weather conditions!
In addition, the membrane was also developed specifically for large batten widths and offers a high level of safety during application.
