Reinforced hydrosafe high-performance vapour retarder, suitable for all fibrous insulation materials



  • The best possible protection for insulation structures thanks to humidity-variable diffusion adaptation with a variation of a factor of over 100
  • Test winner in April 2012 with the German product-testing foundation »Stiftung Warentest«
  • Permanent protection: durability officially, independently tested and confirmed
  • Protected winter building sites thanks to hydrosafe behaviour
  • Suitable for all fibrous thermal insulation (also blown-in insulation)
  • Excellent values in the hazardous substance test, has been tested according to the ISO 16000 evaluation scheme


Can be used as a vapour check and airtightness membranes for all externally diffusion-open structures, e.g. with roof underlay (pro clima SOLITEX), softwood fibreboard or MDF board. For a high level of protection against moisture induced failures in structurally challanging constructions such as diffusion-resistant flat/pitched roofs. Also suitable in extreme environments such as in high mountain regions.
