Transparent full-surface adhesive airtightness and weathering-protection membrane
Advantages
- Protects the structure against weathering during the construction phase
- 3 months of outdoor exposure in Central/Northern Europe, Canada and the northern United States (ASHRAE Climate Zones 4-8); 6 weeks in the rest of the world
- Preparation work is made easier: markings, connectors and penetrations on timber floors remain visible
- Safe working: anti-slip surface, even in wet conditions
- Water-resistant SOLID adhesive ensures quick adhesion to the subsurface and within overlap areas
Areas of application
Temporary protection for floors during construction
Thanks to its full-surface adhesion, this membrane provides temporary weathering-protection for intermediate floors on multi-storey CLT (cross-laminated timber) or wooden-frame buildings during the construction period.
