SOLITEX FRONTA HUMIDA
Breather membrane (WRB) for use behind ventilated pre-wall shells
Advantages
- In accordance with DIN 68800-2: for timber wall structures behind ventilated pre-wall shells
- Protects wall structures against moisture from the ventilation layer
- Protects the building structure during the construction phase: very resistant to driving rain
- 3 months of outdoor exposure
Areas of application
For use as a slightly diffusion-inhibiting breather membrane (weather-resistive barrier, WRB) on mineral-fibre and wood-fibre insulating panels behind a ventilated masonry/brick exterior wall.
