BureValleySchool,Norfolk. External wall insulation (EWI) from Saint-Gobain Weber, has been applied as part of a £3m refurbishment project. Expansion plans included six new classrooms being built and two more created within the reconfiguration of the existing structure.

The EWI system forBureValleySchoolspecified 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 weather resistant surface.
