Filon Over-Roofing - GRP Sheeting for Refurbishing Old Roofs

When asbestos cement roofs need complete repair, the HSE require the least disturbance of asbestos containing material and wherever possible exercise safe containment rather than removal. Filon Over-Roofing achieves these objectives and is specifically designed to combat the problems of an old asbestos roof, which is costly to replace if disposal of original roof is required.

To secure Filon Over-Roofing GRP sheets to the existing roof a unique patented Filon Profix spacer has been developed matching the existing roof profile. Spacers are laid over the old roof along the purlin line to accommodate the original hook bolt fixing then the new GRP over roof of the same profile is laid over the spacers and fixed with self drilling screws through the spacer into the purlin.

Where higher standards of insulation are required, 60mm deep Filon Profix spacers are available that will accomodate a 100mm quilt. In addition, Filon can offer a very effcient and thinner insulation, which is available for use with 25mm deep Profix spacers, to comply with ADL2B within Part L2.

Filon Over-Roofing offers superior benefits and savings over alternative systems :

No structural survey required. Filon Over-Roofing contributes minimal weight to

the roof as the over-roofing elements weigh no more than the weight of water that

the asbestos cement sheets will absorb and retain following a prolonged downpour.

Minimal installation costs resulting from a one fix system. Long lengths sheets

reduce end laps and speed up laying time. No realignment of gutters necessary.

Minimum disruption of occupants, all fixing being carried out externally.

Reduced heating costs from insulation.

No asbestos handling, no complex disposal problems and no landfill tax.

Permanent weather sealed roof created with a minimum service life of 30 years

virtually maintenance free.
