Glass Reinforced Plastic (GRP) otherwise known as Fiberglass is a mixture of polyester resin with glass reinforcing it. This is then coated with a polyester topcoat. The fibres of glass (which are very fine) help strengthen the plastic, which is where the name “fibreglass” originates. Fiberglass has a variety of uses and has been used in a variety of industries for over half a century! It can be applied to stairs, walls, walkways, skylights and many more things! It is great value as it doesn’t require maintenance. It is also very simple to extend or repair should you want/need to do any work on it. It lasts up to three times longer than felt and looks a lot sleeker, because of this you will usually get a guarantee which can be up to 30 years from the date of installation. It is a great cost-effective way to protect your property from rain and the other elements.
