Flame-resistant breather membrane (WRB) for open-jointed cladding, gap width up to 35 mm (1 3/8")
Advantages
- Improved safety: 'not easily flammable', fire classification B-s1, d0 as per EN 13501-1
- Well-protected building components: highly permeable and, at the same time, maximum protection against driving rain
- Not visible behind open-jointed cladding: black fleece with printed marking only in the overlap area
- Highest possible durability and thermostability thanks to the monolithic functional film
- 6 months of outdoor exposure
Areas of application
For use as a breather membrane (weather-resistive barrier, WRB) behind closed and open facades (open-jointed cladding up to a gap width of 35 mm (1 3/8"); cladding width = at least 3 x gap width). Installation onto boarding, wood-based panels and all mat or panel-shaped thermal insulation materials.
