External wall insulation (EWI) from Saint-Gobain Weber, the leading UK formulator and manufacturer of innovative, high performance materials in the facades, concrete repair, tile fixing and flooring systems, has been specified for the remodelling of the Bure Valley School, Norfolk.  Pupils will now enjoy greatly improved classroom facilities and a fresh, bright and vibrant exterior colour scheme, both of which have been achieved with the use of the weber.therm XM EWI and render system.   The refurbishment project received £3m funding from the Primary Capital Programme, a funding scheme for 21st Century Learning.

Bure Valley School was established in 1976 as a local village school and continued expansion has resulted in a complex structure on the large site. Regional population growth required a substantial increase in capacity and plans were drawn up in 2010 for the complete modernisation and expansion of the school. 

Of the 250 pupils, some were being taught in mobile classrooms that had been introduced several years ago. These were swept away in the expansion plans prepared for Norfolk County Council by architects at the NPS Group, whose Norwich office handled the design project. Six new classrooms have been built and two more created within the reconfiguration of the existing structure.  Kier Eastern, Norwich, won the framework agreement as the main contractor who appointed M. Clarke & Sons as the specialist Saint-Gobain Weber EWI installer.

With aesthetics in mind, the architect’s brief was to integrate the renovated section of the school with the new additions. It was also vital to greatly improve the thermal efficiency and performance of the original buildings which were partial cavity wall construction. The Saint-Gobain Weber EWI system met these criteria and the result is a modern, exciting and efficient place of education.

The weber.therm XM EWI system for Bure Valley School specified 60mm of EPS for the original building sections which was mechanically fixed to the substrate.  The first application of 3mm of weber.rend LAC in the weber.therm XM system is applied followed by the meshcloth reinforcement which is encapsulated in another coat of render to form a 6mm total coat.  When dry the surface is primed with weber PR310 a pigmented primer, followed by weber.plast TF150 decorative finish which provides a fine textured, highly weather resistant surface.

The same system and finish was also applied to the new build section with 200mm of EPS insulation fixed to the blockwork to provide a coherent design and thermal performance across the campus. In all, 500m² of weber.therm XM external wall insulated render was applied at this modern and very attractive education establishment in East Anglia.
