Multiplex Super AL
Application

Designed for use as a premium vapour barrier membrane and is suitable for use as part of a high performance torch-on roofing system. It can be applied to a wide range of non-combustible substrates, including metal and concrete decks, subject to use of a suitable primer as required. The product features an aluminium reinforcement which is resistant to alkali and corrosion.

Description

A torch-applied, bituminous vapour control layer (VCL) which is saturated and coated with high quality styrene-butadiene-styrene (SBS) modified bitumen. It has an aluminium/ glass fleece reinforcement, a thermofusible polyethylene film on the underside and is finished on the top surface with quartz sand.

Features and benefits:

  • Torch-on application.
  • Low temperature flexibility at -18°C.
  • Aluminium reinforced.
  • SBS modified bitumen.
  • Rapid, simple installation.
  • CE marked.
