Isocell Timbertex Airtight Vapour Membrane

Placed on underside of attic truss prior to installation of plaster board.

This vapour barrier protects the construction from condensation caused by diffusion. It ensures a controlled and regulated diffusion of water vapour through the thermal insulation. All overlaps and joins must be sealed with AIRSTOP Adhesive Tape, Tape or with AIRSTOP sealant ‘SPRINT’.  Membranes can be sealed to perimeter walls using Isocell Airstop Nahtpaste (Adhesive), or Airstop  Flex Tape in conjunction with Bubi Primer  .We recommend the use of AIRSTOP Cable and Pipe Sleeves or AIRSTOP BUTYL Stretch Flex for penetration points.
