Application

  • Designed to suit requirements of both new build and remedial roofing applications. It can be applied to all suitable non-combustible substrates as an underlay in built-up waterproofing systems or as a vapour control layer on newly built or refurbished flat roofs.
  • The product can also be used as the top layer in certain built-up ballasted waterproofing systems where there is suitable surface protection. The product is not recommended for use as single layer waterproofing.

Description

A polyester reinforced torch-on underlay, saturated and coated with high quality styrene-butadiene-styrene (SBS) modified bitumen. The membrane carrier is a tough polyester reinforcement, giving the material high dimensional stability and mechanical strength. The membrane is finished on both sides with a thermofusible film for fast and consistent torch-on application.

Features and benefits:

  • Independently tested by the British Board of Agrément.
  • Guided (snowflake print) rapid melt film for accurate and consistent torch-on application.
  • Good low temperature flexibility at -25°C.
  • High puncture resistance.
  • High resistance to foot marking.
  • CE marked.

Applications:

  • Designed to suit requirements of both new build and remedial roofing applications. It can be applied to all suitable non-combustible substrates as an underlay in built-up waterproofing systems or as a vapour control layer on newly built or refurbished flat roofs.
  • The product can also be used as the top layer in certain built-up ballasted waterproofing systems where there is suitable surface protection. The product is not recommended for use as single layer waterproofing.
