What Is It?
Well it is a Fibreglass laminate made from cold applied, pre-accelerated, unsaturated polyester resin solution reinforced with chopped strand mat. Then finished with a pigmented polyester top coat and cured with peroxide catalyst to give a monolithic, fully bonded Fibreglass layer of either 450gm or 600gm glass content.
In other words it is a layer of Fibreglass laid to a prepared deck to form a waterproof layer that will probably last a lifetime.
The Fibreglass layer is formed directly onto a new or existing deck and bonds to the decking boards to form a fully bonded roof.
The monolithic skin or laminate contains no welds or glued joints.
The entire roof surface and all the edge detail are formed in one continuous piece of Fibreglass bonded to the roof deck and any associated structures. This means there are absolutely no joints to fail.
All preformed details including outlets, edge trims, flashings etc. are made from Fibreglass so that there can be no difference in the rates of expansion.
We start with a typical roof of traditional felt over timber that has reached the end of its life. A roof that leaks and has already gone through systematic repair over the years to seal against leaks.
Once the entire roof area is prepared we apply all detail to the new roof. Fixing trims as required forming the first part of the monolithic roof. Once all the trims are in place each joint is carefully laminated with Fibreglass 450gm bandage to provide additional structural strength at all joints and roof detail.
Once the deck and trim details are completed the roof is laminated with our special resins. Our resins are formulated for the job they have to do. They are more flexible than ordinary Fibreglass polyesters, have low shrink characteristics (all polyesters shrink as they cure) have low styrene emissions making them more environmentally friendly and safer to use.
The resins are developed to provide a flexible high performance covering that will outperform other roof coverings.
The roof is finally sealed with a further coating of polyester topcoat. This is pigmented to improve both the final appearance of the roof and to seal the fibres in the surface against any water ingress.
The topcoat can be pigmented in any colour, although we recommend a dark grey colour. The topcoat will also stop any UV transmission into the body of the Fibreglass layer and allows additional coatings to be applied to provide a choice of finished textures.
Our Fibreglass (GRP) Flat Roofing Weatherproof Permanent System is a layer of Fibreglass laid to a prepared deck (roof) to form a waterproof flat roof layer that will last a lifetime. The Fibreglass layer is formed directly onto a new or existing deck and bonds to the decking boards to form a fully bonded waterproof flat roof.
