WOLFIN GWSK DA
Description

Bitumen resistant, thermoplastic roofing membrane which helps to optimize the refurbishment of bonded GWSK roof layers. The GWSK DA membranes are equipped with a self-adhesive layer which also has special drains for optimal vapour pressure equalization. The lateral spreading of the moisture and the low diffusion resistance help to speed up the drying of the roof considerably. Due to the black colour of the membrane, a high vapour pressure develops quickly when they it is exposed to the sun rays, causing the roof layers to dry out efficiently.

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.
