Polymeric membrane for ballasted roof waterproofing

Sarnafil® TG 66-18 (thickness 1.8 mm (0.0709 in)) is a multi-layer, synthetic roof waterproofing sheet based on premium-quality flexible polyolefins (FPO), with inlay of glass non-woven according to EN 13956. Sarnafil® TG 66-18 is a hot air weldable, UV-resistant roof membrane. Suitable for use in hot and tropical climatic conditions.

Usage

Roof waterproofing membrane for roofs with ballast (example gravel, concrete slabs, green roof) and / or exposed flat roofs:

  • Loosely laid and ballasted roofs
  • Green roofs
  • Utility roofs
  • Inverted roofs

Roof waterproofing membrane for exposed roof junction zones:

  • Roof waterproofing for junctions and flashings, example wall and parapet junctions, roof lights, etc., which are permanently exposed in installations of Sarnafil® TG 66-18 roof waterproofing systems with ballast.
  • Roof waterproofing for junctions and flashings in installations of all types of Sarnafil® TS 77 and TG 76 Felt exposed roof waterproofing systems.
Advantages
  • Proven performance over decades
  • Resistant to micro-organisms
  • Resistant to root penetration
  • High dimensional stability due to glass fleece inlay
  • Compatible to bitumen
  • Resistant to permanent UV irradiation
  • Resistant against impact load and hail
  • Resistant to all common environmental influences
  • Resistant to mechanical influences
  • Hot air welding without use of open flame
  • Recyclable
