Diamond GRP

Diamond Glass Reinforced Polyester (GRP) is a composite material made from a polyester resin which is reinforced by chopped strand mat (CSM) glass fibres to form a GRP laminate. The Diamond GRP roofing system is constructed from a single-ply laminate applied in situ over 18 mm OSB3 deck. The roof is finished with GRP edge and a coat of Diamond GRP topcoat. When used for roofing, GRP provides a completely weatherproof system without any of the problems associated with traditional flat roofing materials.
