Lightweight GRP Over-roofing was the ideal solution for refurbishment of this fibre cement roof in Salisbury.
The roof at the Harnham Trading Estate was starting to fail, causing water ingress. The rooflights were also becoming discoloured, reducing light transmission into the building.
Industrial Building Solutions of Wimborne, Dorset, installed approximately 500m2 of OP24E over-roofing in asbestos grey to suit the existing Cape Monad asbestos fibre cement roofing sheets, with 25mm thick Profix spacers. These allow a cavity into which insulation material was laid to upgrade the thermal specification of the roof.
The old rooflights covering an area of approximately 50m2 were also replaced during the project.
This created a big impact on light levels within the building, bringing an improved working environment and reduced energy consumption for the building occupant, New Garage (Harnham) Limited.
Andy Green, Director of Industrial Building Solutions, said: “We have used Filon’s over-roofing system for many projects over the years. It’s simple to install, with minimal disruption, because the old roof doesn’t need to be removed – and because it’s so light, no additional reinforcement is needed. As the existing roof dries out the result is an overall reduction in weight – so it’s a win-win situation”
