All-round hydrosafe® high-performance vapour retarder

connect variant with self-adhesive zones


  • Best possible protection against mould and damage to structures thanks to humidity-variable diffusion resistance
  • Can be combined with all fibrous insulation mats and boards
  • Easier handling: can be used on between-rafter and over-rafter insulation
  • Protects the structure against weathering during the construction phase for a roof pitch above 10° (2.1:12”)
  • Protected winter building sites thanks to hydrosafe® behaviour
  • Excellent values in the hazardous substance test, has been tested according to the ISO 16000 evaluation scheme

Areas of Application

For use on roof decking underneath over-rafter insulation as a vapour retarder and airtight membrane that can be subjected to outdoor exposure. It is suitable for use on the inside of supporting structures, e.g. for between-rafter insulation – even for applications where the membrane will be permanently exposed to UV light, such as in unfinished rooms or areas without inner cladding. INTELLO X can be used on structures that are diffusion-open to the outside or are diffusion-tight, e.g. flat/steep roofs and green roofs, after appropriate design calculations.
