Daco-KSD-B Self-Adhesive VCL
Application

Designed for use as a high performance vapour barrier, and is suitable for use within cold-applied roofing systems. It can be applied to a wide range of substrates, including plywood, metal and concrete decks, subject to use of a suitable primer as required.

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 a glass fibre and aluminium composite reinforcement, separating foil on the underside and is finished on the top side with quartz sand, which helps ensure firm adhesion with the subsequent thermal insulation. Joints and overlaps can also be rapidly sealed by means of (hot gas) welding where required.

Features and benefits:

  • Flame free, self-adhesive application.
  • Good low temperature flexibility at -25°C.
  • Aluminium reinforced.
  • SBS modified bitumen.
  • Reliable, environmentally friendly material.
  • CE marked.

Applications:

Designed for use as a high performance vapour barrier, and is suitable for use within cold-applied roofing systems. It can be applied to a wide range of substrates, including plywood, metal and concrete decks, subject to use of a suitable primer as required.
