Sarnavap®-5000 E SA

Sarnavap 5000E SA is a multi-layer self-adhesive vapour control layer 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 VCL can withstand high wind loads: design load up to 2.4kN/m2
  • High adhesion/bonding strength leading to an air tight roof construction
  • High tearing 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
