Stamisol Extreme DW Facade

High-performance rainscreen membrane for highly open cladding

Push the limits with Stamisol Extreme DW, specifically designed for open-joint façades with gaps up to 100 mm or 50% openness. Its reinforced formulation withstands extreme conditions: tested for 10,000 hours of UV exposure, it maintains W1 watertightness and mechanical strength.
Suitable for all types of substructures (timber, metal, insulation), it effectively protects thermal insulation while ensuring optimal breathability to reduce condensation. Compatible with Stamisol accessory systems, it guarantees perfectly sealed detailing.

Durability, design freedom, façade safety

Stamisol Extreme DW is classified Euroclass E (VKF 5.3 / RF2) and provides proven watertightness in accordance with EN 1928 (800 mm water column) and TU Berlin testing. After prolonged UV exposure, it retains its mechanical performance. Its high breathability reduces condensation risk, and its flexibility down to –30°C ensures easy installation, even in winter conditions.

It can remain exposed for up to 24 months before final cladding installation and comes with a 10-year system warranty.
