Jump to:
+44 (0)330 058 0668


Used as an upper layer within a multi-layer waterproofing system.


Membrane composed of styrene-butadiene-styrene (SBS) modified bitumen with polyester reinforcement. The upper surface is finished with slates, with the selvedge protected by a polypropylene film. The lower surface has thermally activated SBS stripes alternated with non-stick stripes, protected by a thermofusible film.

Features and benefits:

  • High performance.
  • Single layer system - torch-on or hot-air method including the overlaps.
  • Flexible until -20°C.
  • CE marked to BS EN 13707.
