Worle Community School
The key to the project’s success is the roof’s construction. Inside, the challenge was to ensure the roof complied with the strict acoustic requirements of Building Bulletin 93. Outside the task was to provide a cost effective insulation solution for roof’s curved surface. The answer was Rockwool DuoRock T/F 85. This superior dual-density board, with its high density, robust top surface met all the project requirements.
“ For this project, Rockwool was far more user
friendly than rigid board, it enabled us to follow
the very complicated curves of the roof”

The spectacular curved roof is a highlight of Worle Community School’s stunning new £1.7 million restaurant. Designed by GSS Architects, the 650m2 rectangular, steel-framed roof structure is supported at its four corners from where it arches gently up and over the cavernous dining hall. Its dynamic, vaulted design is echoed internally by a curved suspended ceiling to create a wonderfully light and airy
restaurant. At the side of the hall is a large stainless steel serving area, attached to a fully equipped kitchen to enable the school
to provide wholesome meals for its 1500 pupils using fresh produce, sourced in and around Weston-super-Mare.
The key to the project’s success is the roof’s construction. Inside, the challenge was to ensure the roof complied with the strict
acoustic requirements of Building Bulletin 93. Outside the task was to provide a cost effective insulation solution for roof’s curved surface - a task made all the more challenging because the presence of the kitchen meant the insulation had to be non-combustible.
Rockwool’s Roofing Consultancy Approach
Rockwool’s roofing consultants worked with GSS Architects and the roofing contractor, Single Ply Services, from the outset to help
develop the best, most cost effective insulation solution for this challenging application. The answer was Rockwool DuoRock T/F 85.
This superior dual-density board, with its high density, robust top surface met all the project requirements: it was flexible enough to accommodate roof’s curve; it required fewer insulation fasteners so it was economical and fast to install; and it offered excellent thermal
and acoustic insulation for compliance with Part L and Part E of the Building Regulations. “For this project, Rockwool was far more user friendly than rigid board, it enabled us to follow the very complicated curves of the roof,” Tony Burgoyne of roofing contractor Single Ply Services.
The roof was waterproofed using the Sika-Trocal S single ply roofing membrane, with the Rockwool DuoRock laid underneath to form a complete acoustic solution. Rockwool even provided the design team with accurate calculations using BuildDesk U-value software
and our rain-noise calculator to confirm compliance with the regulations.
The Benefits of Rockwool’s DuoRock
Equally importantly for the restaurant, Rockwool DuoRock is non-combustible. In common with all of Rockwool’s dual-density roofing boards it is fire-rated for up to 2 hours – which ensures they meet the highest European Reaction to Fire Classification – the single classification system harmonised across all EU member states. It was a great solution.
Rockwool’s Roofing Consultancy team felt the time spent working designers and contractor in developing the insulation specification was
well spent. Since the restaurant opened in October 2007, the restaurant has become the hub of school life for students, teachers and parents, which is the best possible endorsement for the design and construction of this impressive addition to the school.
