A brief history of GRP Fibreglass

GRP (Glass Reinforced Polyester) was discovered in the late 1940’s. It was quickly adopted during the 1950’s and 60’s for a wide range of applications where its corrosive-proof properties, allied with its high strength and excellent appearance, soon proved to be invaluable. Its first main application was for boat building, where it gained acceptance in the 50’s and is still widely used today. The uses for GRP have since broadened to the extent that it has now become the standard material for the construction of small craft, water tanks, building cladding panels, roof lights and of course high performance waterproof coatings. In the last ten years a rapid growth has occurred in the GRP roofing industry as more and more people realise the benefits of GRP.

What is a GRP Fibreglass Roof?

A GRP roof is a single-ply GRP laminate applied in situ over a good quality OSB3 deck. The roof is finished with pre-formed GRP edge trims and a coat of pre- pigmented topcoat. GRP has been used as a waterproofing material for over fifty years for applications as diverse as boats, water tanks, lorry and car bodies, roof lights, ponds and pools. When used to construct a boat, GRP will provide complete waterproofing protection for the boat’s entire lifespan of twenty plus years without the need for maintenance or replacement. This same level of performance is easily replicated on a domestic roof.

The GRP Fibreglass Flat Roof System

GRP Fibreglass roofs are robust and aesthetically pleasing to the eye. It can provide a non slip finish that is suitable for balcony’s or roofs that have foot traffic. The entire roof surface and edge detail are formed as one continuous membrane which bonds to the new roof deck, effectively encapsulating your flat roof in a monolithic skin which contains no joints. This is ideally suited to simple or complex roof designs with lots of protrusions, such as sky lights.

Not only does it look good, it also comes with a 30 year guarantee and is maintenance free. A professionally applied fibreglass roof will last a lot longer than the 30 years. Compared to an average life expectancy of bitumen based materials, the life expectancy of a fibreglass roof is far greater than other flat roof products making it a cheaper option on a year by year basis.
