Polymeric membrane for adhered roof waterproofing.

Jump to:

+44 (0)1707 394444 www.sarnafil.co.uk

Application

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.
