Reinforced Hydrosafe® vapour check made of building paper
Advantages
- Excellent protection against damage to structures and mould thanks to humidity-variable diffusion resistance
- Protected winter building sites thanks to Hydrosafe® behaviour
- Can be combined with all fibrous insulation materials (including blown-in insulation)
- Ecological solution for sealing of the building envelope
- Excellent values in hazardous substance testing, has been tested according to the ISO 16000 evaluation scheme
Areas of application
For use on roofs, walls, ceilings and floors in combination with all fibrous insulation materials, including blown-in insulation, on structures that are open or closed to diffusion on the exterior, after appropriate design calculations.
