Application

Suitable for new build and refurbishment applications on ballasted and protected flat roofs.

Description

Protected PVC single-ply membrane roof system for warm roof constructions. Contains a fungicide for protection against microbe attack. It is FLL approved and has an anti-slip surface, which provides a significant safety factor when walked upon in wet weather.


Features:

  • Suitable for new build and refurbishment applications on ballasted and protected flat roofs.
  • The membranes are manufactured from pliable PVC reinforced with glass fibre.
  • The PVC contains stabilizers, which make the product UV stable and resistant to both high and low temperatures, and remains flexible at low temperatures, during installation and use.
  • Protan Prefabricated G membrane also contains a fungicide for protection against microbe attack and is FLL approved.
  • Protan Prefabricated G membrane has a slip resistant surface, which provides a significant safety factor when walked upon in wet weather.


Durability:

Accelerated weathering tests and performance in service indicates that Protan Prefabricated G membrane should have a life in excess of 30 years.


Fire resistance:
