185 GRP System - Fibreglass Membrane Roofing System

Glass reinforced plastic (GRP) roofing system with premium performance and BBA certification.

The system is always applied to a Polyroof approved OSB3 deck and detailed with Polyroof Pre-formed GRP Trims. The system carries a minimum durability rating of 25 years, providing an exceptionally tough and hard-wearing membrane.

It is suitable for small to medium sized roofs up to 100 m² (for larger roofs, see Polyroof Protec & Protec Evolve), and is available in anthracite grey. The highly impact-resistant finish can withstand regular foot traffic without additional protection, and when combined with an anti-slip finish, the 185 GRP System is a suitable choice for balconies and walkways. The 185 GRP System is supported by Polyroof’s Approved System Guarantees for up to 20 years.
