THE FIRST CHOICE IN GRP ROOFING

BBA CERTIFIED, 25-YEAR GUARANTEE, MAINTENANCE FREE, RESISTS HEAVY TRAFFIC EASY TO SEAL AROUND COMPLEX SHAPES, HIGH SECURITY, COLD APPLIED & CURED FIRE RETARDENT

Advanced Roofing Solutions, incorporating the Topseal system, is a wet laid, GRP laminate made from cold applied, preaccelerated, unsaturated polyester resin solution in styrene reinforced with emulsion bound chopped strand mat. Finished with a pigmented polyster topcoat and cured with peroxide catalyst to give a monolithic, fully bonded GRP layer of either 450gm or 600gm glass content. What a mouthful.

In other words - Advanced Roofing Solutions, incorporating TopSeal system, is a layer of GRP laid to a prepared deck to form a waterproof layer that will last & last & last !

A monolithic laminate that contains no welds or joints.
Designed to give MAXIMUM performance.

The Glassfibre layer is formed directly onto the new deck and bonds to the decking boards to form a fully bonded roof. In this example OSB Sterling Boards have been selected.

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 GRP 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 GRP so that there can be no difference in the rates of expansion. Because the roof laminate is fully bonded it can be applied to form a warm roof without the possibility of intersticial condensation.

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.We then form a completely new deck using sterling OSB3 conditioned boards. These tongue and grooved boards in 2400x600mm are laid to staggered joints to form a completely new decking Once the entire roof area is decked we apply all the detail to the new roof. Fixing trims as required to form the first part of the monolithic Advanced Roofing Solutions roof system.Once all the trims are in place each joint is carefully laminated with GRP 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.
Resins are formulated for the job they have to do. They are more flexible than ordinary GRP polyesters, have low shrink characteristics (all polyesters shrink as they cure!) have low styrene emissions making them more environmentally friendly and safer to use. We use a specially formulated roofing resin developed to provide a flexible high performance covering that will outperform the competition.

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 light grey colour to diminish thermal gain. The topcoat will also stop any UV transmission into the body of the GRP layer and allows additional coatings to be applied to provide a choice of finished textures.

The secret is in the Polymer of which there are broadly two types.
THERMOSETS or THERMOPLASTICS

Thermoplastics.
Thermoplastic molecules generally polymerise end to end to form long chain molecules which will soften under heat. Hence the name thermoplastic. They are usually poor in their resistance to short wave radio wave radiation and will gradually degrade under prolonged UV radiation. Examples of Thermoplastics are Polyethylene, Polystyrene, Polypropylene, PVC, Saturated Polyesters and Nylon.


Thermosets.
Thermoset molecules generally polymerise accross the chain (cross linking) and end to end in order to form a 3D molecule which once polymerised cannot be softened or reworked with heat. Once polymerised they are intrinsically resistant to all forms of short wave radiation. Unsaturated polyesters are so good in this respect that they have been specified by BNFL for the encapsulation and disposal of Nuclear waste, when used as a polymer concrete. Examples of Thermosets are Unsaturated Polyesters, Polyurethanes, Phenolics and Epoxies.

Here's the difference. The Cross Linked Thermosets can clearly be seen on the right.

A Typical Polyester Molecule.

Advanced Roofing Solutions (TopSeal) resin is a solution of unsaturated polyester resin in Styrene where both the Styrene and the Polyester cross link together as they cure, to form a 3D polymer of Polyester & Styrene whose properties may be tailored to optimise them for any application where weather resistance and a superb finished appearance are required. The Diagram above is what all the fuss is about.
