Fibreglass Glass Reinforced Plastic (GRP) is comprised of polyester resin and chopped strand glass fibres, which are mixed together to form a laminate. GRP fibreglass has become one of the most popular forms of flat roofing systems because it is not only a strong material but doesn’t add too much extra weight to the structure.
Cheaper and more flexible than carbon fiber, it is stronger than many metals by weight, is non-magnetic, non-conductive, transparent to electromagnetic radiation, can be molded into complex shapes, and is chemically inert under any circumstances. Applications include aircraft, boats, automobiles, bathtubs and enclosures, swimming pools, hot tubs, septic tanks, water tanks, roofing, pipes, cladding, orthopedic casts, surfboards, and external door skins.
