Simple minds come together on Aztec West project

by Matt Downs

After being re-roofed with BMI Icopal’s Torch-on system, the 4,250m2 flat roof of Unit 800 at Aztec West is reportedly one of the most complex roofs and most secure in Bristol.

“The existing roof had reached the end of its useable life and required full replacement to provide a good quality waterproof covering as well as meet current Building Regulations” says Andrew Hill, Associate Director at Trident. “We were looking for a good quality high performance felt system with a long guarantee. BMI met this requirement with its 20-year product guarantee, good range of high performance felt products and its long-established reputation in the market.”

Andrew added he preferred a high performance felt membrane on this occasion due to the hardwearing nature of felt because the roofs will be regularly accessed for maintenance.

Installed by Mitie Tilley Roofing, the new roof consists of BMI Icopal Total Torch Vapour Control Layer, 120mm BMI Thermazone Torch-on Roof Insulation Boards in the majority of areas and tapered insulation for the remainder, Total Torch Vapour Dispersion Layer and charcoal Thermaweld FireSmart Mineral Capsheet.

Matthew Goddard, Area Director, Roofing, added: “Tapered insulation was designed and detailed by BMI to create falls in the areas of the building that had flat decking, with sumps to the perimeter to keep ponding water to a minimum. Regular inspection visits by the BMI technician ensured that any difficult details were overcome quickly and effectively, ensuring a very high standard of work.”
