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: officially tested and certified performance (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

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.
