Reinforced hydrosafe® high-performance vapour check, suitable for all fibrous insulation materials.
Air barrier, smart vapour control, and dense-pack reinforcement all in one. INTELLO Plus is the keystone to long-lasting airtightness and intelligent vapour control in walls and roofs.
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/steep roofs and green roofs, after appropriate design calculations have been carried out.
