Breather membrane (WRB)

connect variant with self-adhesive strips

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.
