GRP (glass reinforced polyester) is the technical name for what is commonly known as ‘fibreglass’. Originally developed in 1938 for use in insulation, GRP is extremely durable and today is used in a variety of applications across a number of industries. Also known as FRP (fibre reinforced polymer) GRP is extremely versatile, strong and waterproof, making GRP the ideal solution for applications such as roofing systems. The ability to produce different finishes such as nonslip surfaces using GRP, in addition to being able to produce unlimited range of colour options for applications of almost any complexity, means that GRP is now a popular and viable alternative to traditional roofing systems used previously.
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’ in infrastructure or performance throughout the testing period. Additionally, because GRP products are used 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.
GRP products supplied by G & B (North West) Ltd can be made in a number of different colour options (any colour in the BS4800 colour range.) For example, GRP roofing products and accessories can be coated on-site by specialists such as roofing contractors to the end client specification.
GRP can be used for a number of applications including roofing, automotive, construction, marine and industrial, including, boats, car bodies, HGV roofs, and shells, pipes, hygienic linings, tanks, building products, ponds, pools, architectural features, green roofs, flat roofs (commercial and domestic), vertical cladding, walkways, bay windows, wind turbine blades, plus a number of other specialist areas.
GRP has a number of benefits compared to traditional roofing products, especially for flat roofing. There are a number of health & safety benefits from installing a GRP roofing system because GRP products are cold laid and therefore does not require any form of heat treatment, helping to protect installers and the general public. As GRP roofing systems are cold-applied they are not subject to the same prohibitive insurance premiums levied at installers using hot-works. Unlike traditional flat roofing systems, GRP flat roofs are extremely durable and completely waterproof, plus they can be finished in any wide range of colours and include options such as nonslip finishes. The entire area on a GRP roof is encapsulated into one single continuous GRP membrane and there are no seams, joints or welds. It is also completely UV resistant. GRP roofing systems are also highly adaptable allowing conversion of the roof area to include features such as balconies or walkways within the roof area. Special features such as roof lights can also be included within a GRP roofing system. GRP roofing systems can also be used instead of pitched roofs or to make special features. The major benefit of GRP roofing comes from the fact that a high-quality GRP roofing system which is installed correctly should remain leak-free for life.

The surface and colour of a GRP laminate can be modified to your requirements. A choice of smooth or textured finishes can be achieved in any colours from the BS 4800 range.
GRP systems are ideally suited to adverse weather conditions and temperature extremes. As GRP is used to make boats and pond liners, it performs well when exposed to cold climates or heavy rain. GRP systems are capable of delivering maximum protection in excess of 50 years. Whilst GRP may not be suitable for applications above 100°C it will perform well where normal temperature extremes are found within global environmental conditions. GRP can withstand dilute acid conditions, however it is unsuitable for prolonged immersion in alkaline solutions. A GRP roof is also fully bonded to the surface of the decking boards so it is very resistant to wind uplift.
While the process for laying a GRP roof is straightforward, there are a few rules of thumb that must be followed before installing a Cure It GRP roof. So it is advisable to attend a training or demo day regularly held at depot in Cork before attempting to install a GRP roof.
