Compagnie St-Gobain - New plant

SAINT-GOBAIN to launch ITS first LOW-CARBON
STONE WOOL INSULATION plant in the UK

Saint-Gobain has announced the launch of a new low-carbon stone wool insulation plant in the UK, which will be located on a site owned by the Group in Melton Mowbray, Leicestershire, and is expected to begin production in 2027.

The facility will initially produce 50,000 tonnes per year of high-performance stone wool insulation for the UK market with the potential to double its output to 100,000 tonnes per year.

The new manufacturing facility will benefit from cutting-edge technology, including a fully electric furnace, powered by renewable electricity. This flagship investment will help customers reduce the embodied carbon of construction projects by lowering the CO₂ (scope 1 and 2) footprint of stone wool insulation[1]. It will help meet the country's growing demand for both stone wool and low-carbon solutions.

New low-carbon stone wool manufacturing further reinforces Saint-Gobain's comprehensive offer to customers in the UK that includes fully tested systems incorporating the Group's existing plasterboard, construction chemicals, glazing, insulation and steel frame structural systems. Together, these solutions for light and sustainable construction make Saint-Gobain the undisputed leader in building envelopes in the UK and will contribute to driving further growth.

This project is part of Saint-Gobain's commitment to achieving net zero carbon emissions by 2050.
