Sarnavap®-5000 E SA

Self-adhesive vapour barrier

Sarnavap®-5000 E SA is a multi-layered, self-adhesive vapour barrier manufactured from polymer modified bitumen with a glass-fibre matt reinforcement and an aluminium foil top layer.

  • Ease and speed of installation from self-adhesive properties
  • Can be used in a fully adhered roof build-up. No additional fasteners required for securing the thermal insulation boards to the structural deck
  • Temporary waterproof top layer for up to 4 weeks, without the requirement for additional weight/ballast and/or mechanical fastenings
  • High self adhesion strength allows high wind design loads from 2,4 kN/m2 to 2,8 kN/m2
  • Provides an air tight layer
  • High tear resistance to foot traffic during roof build up activities
  • High water vapour resistance makes it suitable in combination with all types of membranes
  • Accommodates a wide range of roof system, deck types and substrate combinations
  • Can be bonded onto flashings, inclined or vertical surfaces
