Protan UK Self-Adhesive Air Vapour Control Layer
Application

For use in mechanically fixed and adhered PVC single-ply membrane roof systems as an air vapour control layer.

Description

A self-adhesive, bituminous air vapour control layer (AVCL) that forms a barrier against vapour and gases. It consists of a self-adhesive, low thickness bituminous compound self-protected by a glass fibre and a reinforced aluminium film.

The glass fibre and polyester reinforcement provide excellent resistance to puncture and foot traffic damage. For use in mechanically fixed and adhered PVC single-ply membrane roof systems as an AVCL.

Features/ Benefits:

  • Waterproof and self-adhesive.
  • Cold applied without the use of flames.
  • Vapour, radon and methane gas barrier.
  • Reinforced with glass fibre.
  • Protected with reinforced aluminium film.
  • Excellent puncture resistance and tensile strength.
  • Polyester surface accepts most polyurethane adhesives.

Application:

For use in mechanically fixed and adhered PVC single-ply membrane roof systems as an air vapour control layer.
