Thermally efficient Multi-Therm polyisocyanurate (PIR) insulation roofboard from EcoTherm is contributing to the impressive green credentials of a new ‘eco’ school building in Darlington. Approximately 2,000 square metres of 120mm Multi-Therm are providing energy saving insulation in a sedum-planted roof for the new Northwood Primary School. Scheduled for completion in December 2009, the timber-framed building has been designed and built under the Government’s Primary Capital Programme using the latest sustainable technologies and materials and is expected to achieve an ‘excellent’ Building Research Establishment Environmental Assessment Method (BREEAM) rating.
