Self-adhesive Vapour Control Layer & Carrier Membrane

S-Vap® HD SA is an elastomeric self-adhesive vapour control layer and carrier membrane made of polymer modified bitumen with an aluminium composite and glass combination inlay.  The top suface has a sanded finish. 

  • Ease and speed of installation, due to self-adhesive property of backing.
  • Can be used in a totally adhered roof build-up. No additional fasteners required for securing the thermal insulation boards to the structural deck.
  • Can be used as temporary waterproof layer for up to 4 weeks, as a top layer without the need for additional weight/ballast and/or mechanical fastening.
  • Due to its high adhesion strength the VCL and carrier can withstand high wind loads; design load up to 3.2 kN/m2.
  • High adhesion/bonding strength leading to an air tight roof construction.
  • High tearing resistance under foot traffic makes it ideal for use on profiled metal decks.
  • High water vapour resistance makes it suitable in combination with all membranes.
  • Wide application range, in regard to use in different system applications and/or in combination with different structural deck types, substrates.
  • Improved fire resistance achieved by added flame-retardant.

Can be bonded on roof slopes and up vertical abutments.
