SOLITEX WELDANO 3000
Diffusion-open, weldable roofing underlay membrane
Advantages
- Reliable seam sealing: homogeneously weldable
- Suitable for use under roof-integrated solar panels
- Excellent occupational safety: non-slip and abrasion-resistant surface
- Suitable as a roofing underlay to meet the most stringent requirements
- Maximum protection: diffusion-open, rainproof against driving rain, and highest hail-resistance HR 5 (Swiss VKF/AEAI directive) and as per EN 13583
- Easy to work with: robust with extremely high tear-resistance
- Also keeps structural elements dry during the construction phase: excellent protection against driving rain thanks to monolithic functional film
- Cutting and welding service available for SOLITEX WELDANO 3000
Areas of application
For use as a 3-ply diffusion-open, homogeneously weldable, rainproof/watertight roofing underlay membrane. Suitable for installation over pressure-resistant subsurfaces, e.g. timber sheathing, wood-based panels and wood-fibre underlay panels, and under roof-integrated solar panels.
