KEY BENEFITS OF SENTINEL GRP
GRP Stands for ''Glassfibre Reinforced Plastic'', more commonly known as 'Fibreglass'
it is a very strong and robust material - seven times the flexural strength of steel - yet very lightweight with the high energy absorption properties which have made it the material of choice for racing cars, boats, baths and even aeroplanes.
This system is Durable, Attractive, Cost Effective, Maintenance Free and can be Cold Applied i.e. no blow torches or live flames.
The Sentinel GRP is a specially developed resin system that accommodates everyday structural expansion and contraction and can be moulded and shaped into even the most complex of architectures. Sentinel GRP is a long term, leak free and value for money system for flat roofs of any shape and size, from small porches to large domestic and commercial projects. GRP roofing technologies are extensively used for refurbishment or new roofs, by local authorities, architects, and major building contractors throughout the UK.
