GRP Fibreglass
Glass Reinforced Plastic (GRP) is comprised of polyester resin and chopped strand mat glass fibres, which are mixed together to form a laminate. GRP fibreglass has become one of the most popular forms of flat roofing systems because it is not only a strong material but doesn’t add too much extra weight to the structure.
Durability: GRP roofing systems have a reputation for their strength and durability which is one of the main reasons they are used. If you follow the correct guidelines or hire a professional company who will install the material correctly, your roof will remain in place without problems for years to come.
Weight: It is a great option for lightweight and green roofs. If other materials are too heavy for a structure then fibreglass will not only offer similar levels of protection, it also works well on more complex roof shapes.
No Joints: As the material is in liquid form it also means there are no joins or seams left on the roof surface after installation. This creates a smooth finish that other forms of roofing systems struggle to match.
Repairs: These are made incredibly easy thanks to the material being used. Not only is it a tough and durable solution but making repairs couldn’t be simpler. Maintenance can also be carried out by the property owner to a very high standard.
Aesthetics: GRP fibreglass comes in a wide range of colours which provides a great level of choice for property owners. If you have a specific colour scheme on the property you’re looking to match against, this is far more likely to be possible with GRP.
