Sarnavap®-5000 E SA

S-Vap 5000E SA is a multi-layer self-adhesive vapour barrier made of polymer modified bitumen with a glass-fibre mat reinforcement and an aluminium foil as top layer.

  • Ease and speed of installation, due to self-adhesive property of back layer and its specific weight.
  • 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 vapour barrier can withstand high wind loads; design load between 2.4 kN/m2 to 2.8 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.
  • Can be bonded on roof slopes and up vertical abutments.
