Application

Designed for use as a high performance cap sheet, and can be used as the final waterproofing layer on a variety of TechnoNICOL built-up roofing systems (e.g. torch-safe and full torch-on specifications). The product is compatible with all common bituminous underlay membranes.

Description

A torch-applied, bituminous cap sheet, which is saturated and coated with high quality styrene-butadiene-styrene SBS modified bitumen. It has a 250 g/m² polyester fleece reinforcement, a thermofusible polyethylene film on the underside and has a slate surfaced finish. The product also incorporates a special graphite additive within the coating to provide fire protection properties.

Features and benefits:

  • Torch-on application.
  • Includes graphite technology which actively prevents spread of flames on the roof.
  • Good low temperature flexibility at -25°C.
  • SBS modified bitumen.
  • Tough 250 g/m² polyester reinforcement.
  • CE marked.
