Application

Designed for use as a high performance vapour barrier, and is suitable for use on either metal profiled or plywood decking, and in areas prone to increased temperatures and moisture levels (e.g. factories, swimming pools, gyms).

Description

A cold-applied, self-adhesive bituminous vapour control layer (VCL) which is saturated and coated with high quality styrene-butadiene-styrene (SBS) modified bitumen. It has an integrated aluminium foil layer, a glass fibre reinforcement and is finished on the underside with a removable siliconized film.

Features and benefits:

  • Flame free, self-adhesive application.
  • Tough, mechanically resistant membrane.
  • Simple, fast installation.
  • Low temperature flexibility at -25°C.
  • Aluminium lined.
  • CE marked.

Applications:

Designed for use as a high performance vapour barrier, and is suitable for use on either metal profiled or plywood decking, and in areas prone to increased temperatures and moisture levels (e.g. factories, swimming pools, gyms).
