Breather membrane (WRB)
Advantages
- Very robust: strong, 3-ply structure
- Dry building components: pore-free TEEE functional film actively transports moisture to the outside
- Easy to work with: high nail pull-out resistance
- For use behind closed facades
- 3 months of outdoor exposure
Areas of application
For use as a breather membrane (weather-resistive barrier, WRB) behind closed facades. Installation over sheathing, wood-based panels and all mat or panel-shaped thermal insulation materials.
