Fibreglass Flat Roofing
Fibreglass is a versatile material made of plastic and glass fibres. It’s a popular choice for flat roofing because of its waterproof nature, supreme durability and ease of adjusting to a specific roof. Fibreglass isn’t a cheap temporary measure – it’s an investment in a roof that can last for decades with proper maintenance.
How is a fibreglass roof installed?
Fibreglass is installed in a three-layer manner, starting with a coat of resin, then a layer of GRP matting, then a top coat resin.
What is the purpose of the initial coat of resin?
The initial coat of resin is applied to the surface that the fibreglass will be installed on – ideally, timber decking. It is done to create a solid, totally smooth surface for the fibreglass matting to be placed on.
What is the purpose of the GRP matting? What is GRP?
GRP is just another name for a specific kind of fibreglass often used in a roofing context: glass-reinforced polyester. This is what the matting that forms the middle layer of a fibreglass roof is made out of. The GRP matting forms the main bulk of the fibreglass installation. After the matting is put in the top coat is applied.
What is the purpose of the top coat resin?
The topcoat forms the final, protective layer. It can be pigmented in order to achieve a specific colour – it will be what people see when they see the roof after all.
