GRP (Glass Reinforced Plastic) is otherwise known as Fibreglass, is made up of chopped strand mat made from glass fibres which are laid in situe and then held together with layers of polyester plastic (resin) which becomes hard after being cured, which can’t be cut with a knife. Once cured it becomes a very tough material which can be formed to any size, shape, colour or thickness.
A key benefit is that it is light weight making it ideal for roofs but extremely secure so it does not compromise on security.
How long will it last for? The truth is no one actually knows some of the first roofs completed over 30 years ago show no signs of deterioration. The building research establishment [bre] conducted a survey which showed the condition of several GRP buildings around 25 to 30 years old to be structurally sound.
Fibreglass has a long lifespan and with our Topseal roofing system comes with a 25 year guarantee. GRP is used for various things such as boats, swimming pools, ponds, water tanks car bodies ect.
