Why we use GRP to construct all of our Garden Offices. GRP is corrosion and weather resistant which makes it a perfect component for most indoor or outdoor products. It is a popular alternative over metal, wood, or plastic. Where exposure to harsh environments is a concern, GRP can aid resistance to UV light, extreme temperatures, salt air, and a variety of chemicals. The high strength properties of GRP allow for less material to be used than other more traditional structural materials thus lowering cost and weight. Therefore glass reinforced plastic will act as a satisfactory solution to the corrosion problems and come at a very affordable cost. Also, glass fibre-reinforced plastic has a low environmental impact. The use of composites in construction has many advantages: they are light, quickly installed, require little maintenance and are very durable. GRP is much more environmentally friendly than people generally realise.
