What is GRP?

GRP (glass reinforced plastic) is the technical name for what is commonly known as ‘fibreglass’. Originally developed in 1938 for use in insulation, GRP is extremely durable

GRP is extremely versatile, strong and waterproof, making GRP the ideal solution for applications such as roofing systems. 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. 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.

GRP flat roofing meets British Standards to BS476

The GRP roofing process ensures that your roof is completely sealed with no joints meaning that even the smallest drop of water can’t seep through. Once installed you won’t have to do any maintenance to the roof, leaving you with total piece of mind.

A GRP flat roof meets British Standards to BS476 part 3 FAB and comes with a comprehensive guarantee. GRP Roofing can resist heavy traffic and can be sealed with a non slip coating, therefore suitable for balconies and walkways.

How long will it last?

Many glassfibre laminates made during the early days of GRP production in the 1940s are still in use today. Extensive testing has demonstrated the typical life expectancy of a GRP roof product to be well in excess of 50 years. And, tests conducted to date have shown ‘no deterioration’ infrastructure or performance throughout the testing period. Additionally, because GRP products or use in extreme conditions such as underwater, when used in the manufacture of boats, a GRP product applied by a specialist company could be expected to last a lifetime.
