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.

Building projects with INTELLO and INTELLO PLUS
A success story that really rocks!
Although not taken seriously by many when it was first launched, the INTELLO vapour check membrane with humidity-variable diffusion resistance revolutionised construction practice back in the early 2000s. Since then, it has come a long way: an established part of best building practice, the first humidity-variable vapour check membrane with an ETA, certified as fulfilling Passive House standards, and with excellent results in hazardous substance testing. 20 years on from its market launch, it has been fitted on countless projects – ranging from tiny houses right through to multi-storey buildings – on ceilings, roofs and walls to ensure the integrity of the airtightness layer.
