INTELLO
Hydrosafe® high-performance vapour check, suitable for all fibrous insulation mats and boards
Advantages
- Best possible protection against moisture damage to structures and mould because this product is humidity-variable with a variation of a factor of over 100
- Permanent protection: performance tested and certified by independent testing authority (ETA-18/1146)
- Protected winter building sites thanks to hydrosafe® behaviour
- Can be combined with all fibrous insulation mats and boards
- Easy to work with: dimensionally stable, no splitting or tear propagation
- Excellent values in hazardous substance testing, has been tested according to the ISO 16000 evaluation scheme
Areas of application
Vapour check (alternate terms: vapour control or retarder) membrane for use on roofs, walls, ceilings and floors on structures that are open or closed to diffusion on the exterior, e.g. flat/pitched roofs and green roofs, after appropriate design calculations have been carried out.
