Hydrosafe® high-performance vapour check with self-adhesive strips, for external insulation and roof refurbishment
Advantages
- Excellent protection against mould and moisture damage to structures thanks to humidity-variable diffusion resistance
- Easier handling: can be used with external insulation and on refurbishment projects between two layers of mineral wool insulation
- Protects building structures against weathering during the construction phase for roof pitches of 10° (2.1:12) and higher
- Protected winter building sites thanks to hydrosafe® behaviour
- Excellent values in hazardous substance testing, has been tested according to the ISO 16000 evaluation scheme
- Quick and reliable adhesion thanks to the integrated ‘connect’ self-adhesive strips on the long edges of the membrane
Areas of application
When installed directly on top of a hard subsurface underneath exterior insulation, the INTELLO X connect vapour check (alternate terms: vapour control or retarder) membrane can be combined with all fibrous insulation materials (including blown-in insulation materials).
In the case of refurbishment from the outside and installation between two layers of insulation, the choice of insulation materials for the two layers is limited to mineral or rock wool. The thickness of the external mineral wool insulation needs to be calculated on a project-specific basis; please contact Technical Support at pro clima in Germany for assistance.
This membrane can be used on building components that are diffusion-open to the outside or are diffusion-tight, e.g. pitched, flat or green roofs, after appropriate design calculations have been carried out.
When used on the inside of insulation installed between rafters or wall framework in combination with fibrous insulation mats and boards, this membrane may only be installed onto a hard subsurface or else with additional taping of membrane overlaps with TESCON VANA.
