GRP Flat Roofing

Why Choose GRP Roofing for Your Flat Roof?

GRP stands for ‘Glass Reinforced Plastic’ a material made from a polyester resin, which is reinforced by chopped strand mat glass fibres to form a GRP laminate. It is a very popular composite material to use due to the fact that not only is it very strong but also surprisingly light.

Vapour Control Layers For Flat Roofs

Why a Vapour Control Layer is Essential in a Flat Roof

A vapour control layer helps you shield your building from the consequences of condensation. Condensation is generated when warm moist air rises and condenses into a liquid on contact with the cooler areas above the insulation. The notion behind a vapour control layer is to install it on the room side of the insulation so it stops the passage of warm moist air entering the structure.
