A UKAS-accredited construction testing laboratory at East Leake running two full-scale fire resistance furnaces, rebuilt in 2023 under a £7m investment, which orient vertically or horizontally and take partitions up to five metres. Fire resistance sits alongside acoustic and structural testing on the same specimens. The centre is owned by Saint-Gobain and shares a site with British Gypsum, but is accredited and open to external clients — worth knowing when weighing the independence of a test report.
