Description

Bitumen resistant, thermoplastic roofing membrane with integral glass fibre reinforcement and self-adhesive layer. Due to its special formulation without additional fire proofing agents, it has a very low fire load and thus offers a very high fire protection effect. In the event of fire, the special formulation, combined with the integrated protective fleece, prevents the fire from burning through the membrane down to the thermal insulation.

WOLFIN GWSK membrane consists of the same materials as WOLFIN IB membrane, with the addition of integrated fleece reinforcement and a self-adhesive layer.

Features:

  • Free of toxic heavy metals and flame retarder.
  • High water permeability.
  • Highly chemical resistant.
  • Highly polymeric compound: > 94%.
  • Long proved duration (> 30 years).
  • Ozone and UV resistant.
  • Root and rhizome resistant according to FLL.
