What is GRP?

What is GRP?

GRP refers to glass fibres that have been woven into a matt and kept tightly together by levels of polyester plastic resign. This results in a strong but lightweight product that is perfect for both new and existing roofs.

GRP has been used for many years; in fact, its use can be traced back to 1938. At Findley Roofing & Building, we are fully approved and the local leaders when installing GRP roofing in the North East.

What does GRP stand for?

Glass reinforced plastic – simple but effective.

Glass reinforced plastic is a proven winner when it comes to the application of a new roof.
