At the new £36 million Teddington School in Middlesex, BriggsAmasco installed some 4,000m2 of roofing elements to meet the project’s strict environmental and performance specifications. The UK’s leading waterproofing and roofing specialist overcame severely restricted access – utilising an on-site tower crane – to deliver the school’s complex roofing system.

With the school’s grand opening set for September 2010, BriggsAmasco had to complete the entire roofing installation within a tight timeframe. To achieve this without compromising on quality or performance, the company specified and installed a durable roofing system comprising PermaTEC Hot Melt and Sarnafil PVC membrane, both offering fast and efficient application processes.

BriggsAmasco applied the PermaTEC Hot Melt directly onto the building’s concrete roofing substrate, before insulation and paving slabs were installed on top to form the inverted roof system. With an inverted roof, the main insulation material is applied on top of the weatherproof covering, so that the complete roof construction including covering remains warm during winter months and ambient throughout the summer.

For the new-build’s higher level timber deck, BriggsAmasco also installed 1,250m2 of Sarnafil PVC membrane which was then followed by the installation of a series of large circular rooflights. Providing a lightweight, yet watertight, roofing solution –Sarnafil is regularly specified for its long term durability and high quality performance.

Faced with a series of logistical challenges, BriggsAmasco used its vast expertise to ensure these wouldn’t affect the project deadline. During the installation, the school provided only one access route with restricted access. To overcome this, the company had to utilise a tower crane for the distribution of materials across the site. With many other trades on-site, the roofing specialists worked closely with the main contractor to co-ordinate a complex delivery timetable for maximum efficiency.

By using sustainable materials, high specification and careful consideration for both waste and transport, BriggsAmasco ensured the roofing installation was delivered to the finest standard possible. With a thorough design and delivery of the mixed-specification roofing systems, the company also helped the building to achieve its BREEAM rating of ‘Excellent’.
