Reinforced hydrosafe® paper-based vapour check

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

Vapour check (alternate terms: vapour control or retarder) membrane 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.
