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.

DELTA-XX PLUS® STRONG corresponds with DIN 4426 with large-format tiles.
Whether it is ventilated or unventilated pitched roof structures with or without formwork – DELTA-XX PLUS® STRONG is suitable for a wide range of applications. In addition, the membrane can also be used as temporary roofing for up to four weeks, giving the roof reliable protection against the elements during the construction phase. The roofing membrane can also be used as a base layer under metal roof coverings, fibre cement panels or slate, as well as façade membrane behind ventilated cladding with closed joints.
