WHAT IS GRP FIBREGLASS ROOFING ?

All you need to know about GRP FIBREGLASS ROOFING ...

GRP Stands for Glassfibre Reinforced Plastics, also referred to as Fibreglass, Composite Plastics, and in the USA, FRP. It is an amazingly versatile material, and one that is little understood in industry, but which has truly immense potential across a wide spectrum of applications.

Its vast range of properties can be confusing to the uninitiated. It is a Plastic� but it displays few of the disadvantages of conventional �thermoplastics� in everyday use.

For instance, it will not melt, but will burn in a similar way to wood, but can be easily and cheaply made fire retardant. It is very strong - seven times the flexural strength of steel � yet very lightweight with the tremendous energy absorption properties which have made it a common material for racing cars, boats, baths & even aero planes.

However, GRP is a moulded product which requires some sort of former or tool from which it is moulded in to or on to. In it simplest and most common form, know as �hand-lay�.

A typical roof would be constructed as follows :

1. Remove Existing Felt/Chippings & Deck. Expose Existing Roof Joists.
2. Ensure Poor Water Drainage is improved usually with timber firings.
3. Re deck roof area with 18mm External Grade Ply.
4. Specially made pre moulded edging trims, flashing trims, fillets trims are fixed.
5. Matting is cut to size and impregnated with special resin on to deck to form a seamless membrane.
6. Once curing time has elapsed a pigmented top coat resin is applied to the whole roof.
7. Where roof meets wall a lead flashing or grp flasing is installed.
8. Where roof meets roof tiles GRP roof will be extended under the tile roof.
9. Waste is removed from site.
10. A 20 year guarantee is issued.
