RAL FIBREGLASSING
ANSWERING YOUR QUESTONS
"WHAT IS GRP?"
GRP stands for Glass Reinforced Plastic. It is also called Fibreglass. It is a composite material consisting of plastic reinforced with glass fibres. Sheets of glass fibre strands (chopped strand mat) are overlaid with polyester resin, the resin is pre-mixed with a catalyst (hardener) to create an irreversible chemical hardening. It is strong, durable, light and extremely versatile. It's properties make it the ideal choice of material for water proofing.
"WHY IS A FIBREGLASS ROOF BETTER THAN A FELT ROOF?"
Traditional felt roofs are not as durable or strong as fibreglass roofs. Fibreglass looks better, lasts much longer and is safer to install, it requires no maintenance and is one of the most fire retardant roofing materials available. It is also UV resistant. Felt roofs have seams which can often fail and let water in, a GRP roof has no seams, it is installed as one continuous membrane bonded to the roof deck, making it 100% water-tight.
"WILL IT LAST A LONG TIME?"
Fibreglass won't rust like metal or rot like wood. It can't be pierced or ripped like rubber and it won't flake off like paint, so for longevity its an excellent material. A professionally installed GRP Roof can last for 30 years or more.
"HOW DO YOU DO IT?"
We prepare the surface to ensure a strong bond, cut the fibreglass mat from a roll and tailor it to fit the job, then, using a bucket and roller, wet the fibreglass mat into place with the liquid plastic (polyester resin), moulding the GRP to the required surface. Catalyst is pre-mixed with the resin to create a chemical hardening. Finally the top gel coat is applied, again using rollers and brushes, to leave a slick, seamless, waterproof membrane.
"IS IT EXPENSIVE TO INSTALL?"
Our fibreglass linings compare very well price wise to the alternatives out there on the market, but when you factor in the longevity GPR offers and the peace of mind it gives that it won't leak, a fibreglass lining is very cost effective.
"ARE THERE ARE CHOICE OF COLOURS?"
Yes. We are able to supply gel coats in a variety of colours. Our most popular colour choices for roofs and ponds are Grey and Black. Blue is our most popular colour for swimming pools. But many more colour options are available, please contact us to discuss your requirements.
"CAN I CHOOSE A NON-SLIP FINISH?"
Yes. We can install non-slip finishes to the surface of our fibreglass linings, which can be an essential safety feature for balconies, swimming pool steps or anywhere a non-slip surface is required.
