Polyvap

A range of high performance, aluminium cored vapour control layers (VCLs) coated with a high quality polymer modified bitumen coating. The underside of Polyvap TT and Polyvap TS are protected by Polyflam, a special polyethylene film which melts upon torching. In the Polyvap TT version, the top surface is also protected by a layer of Polyflam, providing a bitumen rich surface. The top surface of Polyvap TS has a coating of fine sand thereby enabling the use of bitumen or Polyglass polyurethane adhesive to bond insulation to the upper face of the VCL. Polyvap SA is a self-adhesive membrane manufactured using ADESO® technology and can be incorporated in to a completely flame free ADESO® self-adhesive roofing system.

Features and benefits:

• Torch-on and self-adhesive applications available.
• Aluminium core stops ingress of water vapour and damage to roof construction.
• Durable polymer modified bitumen coating.
• Cost effective performance.
• Part of a complete package of waterproofing components.
