GRP (Glass Reinforced Plastic) is just different name for Fibreglass and it’s made from fibre reinforced plastic using glass fibre. The fibres may be randomly arranged, flattened into a sheet or woven into a fabric.
Fibreglass is combined with catalysed resin to form a strong and durable composite. GRP Fibreglass is durable, flexible, waterproof and lightweight material and that’s why is perfect for flat roofs. GRP Roofing can be used for both domestic and commercial properties, being suitable for the likes of sheds, garages, extensions and balconies.
