Filon’s lightweight GRP Over-roofing was the perfect solution for refurbishment of this large asbestos cement roof in Bradford.
Yorkshire Water’s Buttershaw Depot Building in Bradford, was constructed in 1971, using a steel portal frame with an asbestos cement roof.
Degradation of the original roof had resulted in water ingress leading to other problems, so in 2010 a refurbishment programme was planned. Yorkshire Water’s requirement was simply to make the building wind and water proof and extending its working life by ten to fifteen years.
First, the building loading would not allow a metal roofing system to be used.
Second, removing the existing asbestos roof would present a significant health & safety hazard.
Lightweight GRP FILON Over-roofing met both these critical requirements. FILON Products worked with main contractor MITIE Tilley Limited to ensure the correct specification and installation of the roof.
The FILON GRP Over-roofing sheets were manufactured to match the existing profile of the asbestos sheets. They were then installed over the existing roof, using FILON’s patented profix spacer system.
The extreme lightness of FILON Over-roofing, compared to metal profiled sheets allows for an extremely simple solution to the problem. Removing risk of exposure to and cost of disposing the asbestos.
Furthermore, FILON Over-roofing is simple to install and greatly reduces time on site.
