Waterproofing membrane for exposed flat roofs:

  • Fully bonded roof surfaces with contact adhesive Sarnacol® 2170/ 2172 Spray or Sarnacol® 2121 depending on substrates.
  • Enhancement of solar reflection of existing polyvinyl chloride (PVC) roofs (relevant only for colour RAL 9016 SR).

Roof waterproofing membrane for exposed roof junction zones:

  • Roof waterproofing for junctions and flashings, e.g. wall and parapet junctions, roof lights, etc., which are permanently exposed in installations of Sarnafil® G 410-20 EL roof waterproofing systems with ballast.
  • Fully bonded junction areas with contact adhesive Sarnacol® 2170/ 2172 Spray.
  • Roof waterproofing for junctions and flashings in installations of Sarnafil® G 410 EL Felt type exposed roof waterproofing systems.

Description

A 2 mm thick multi-layer, synthetic roof waterproofing sheet based on premium-quality polyvinyl chloride (PVC) containing ultraviolet light stabilizers and flame retardant according to BS EN 13956.

It is a hot air weldable roof membrane formulated for direct exposure and designed for use in all global climatic conditions. The membrane has a unique lacquer coating applied to the top of the membrane to resist staining from airborne dirt and pollutants.

Features and benefits:

  • Lacquer coated surface.
  • Various colours are available.
  • High reflectance properties for high cool roofing characteristics (relevant only for colour RAL 9016 SR).
  • Resistant to permanent UV irradiation.
  • High dimensional stability due to glass fleece inlay.
  • Resistant against impact load and hail.
  • High water vapour permeability.
  • Resistant to all common environmental influences.
  • Hot air welding without use of open flames.
  • Recyclable.
  • CE marked to BS EN 13956 and manufactured in accordance with BS EN ISO 9001 and BS EN ISO 14001.
