Breather membrane (WRB) for open-jointed cladding, gap width up to 50 mm (2")
Advantages
- Extremely robust and UV-stable: UV ageing test carried out with 10,000 h instead of 5,000 h
- Dry building components: pore-free TEEE functional film actively transports moisture to the outside
- Well-protected building components: permeable, extremely high tear-resistance, windproof, rainproof and waterproof
- Not visible behind open-jointed cladding: black fleece with printed marking only in the overlap area
- 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 50 mm (2") and 40% open area). Installation onto boarding, wood-based panels and all mat or panel-shaped thermal insulation materials.
