Moisture control for roof and wall systems

Vapour barrier membrane selection should match the roof or wall assembly, insulation position and local project requirement. Buyers usually compare water resistance, vapour control, roll strength and installation method before confirming samples.

Typical selection points

  • Confirm whether the membrane is used under roof coverings, behind wall cladding or near insulation layers.
  • Review roll size, GSM, surface colour and compatibility with tapes or fixing accessories.
  • Use storage and installation notes to avoid site damage before final covering.

Certification and export support

  • Certificate No. VCP-12263 covers waterproof breathable membrane and vapour barrier membrane references.
  • EN 13859-1:2014 and EN 13859-2:2014 information can be provided for buyer review.
