SAINT-GOBAIN TO INVEST €120 MILLION
IN NEW GLASS WOOL PRODUCTION CAPACITY IN FRANCE

Saint-Gobain, through its insulation subsidiary ISOVER, will invest €120 million in the coming years, starting in 2022, to increase its insulation production capacity in France and support the acceleration of the energy renovation market.

These investments will involve both increasing the capacity of existing ISOVER production lines and creating a new line. Today, ISOVER has three glass wool plants in France, located in Chalon-sur-Saône, Chemillé and Orange. By 2025, in response to very strong demand driven by energy renovation, Saint-Gobain will bring to the French market more than 70,000 additional tons of glass wool insulation (including 11,000 tons as early as 2023), which will enable the equivalent of 100,000 additional homes to be renovated each year.

Of the €120 million, €20 million will be specifically dedicated to the decarbonization of production and the development of the circular economy. This will enable the installation of a treatment unit for deconstruction waste to be reincorporated into the production process as a substitute for virgin raw materials, and an increase in the proportion of recycled glass used in the production process to 80% by 2025.

These new investments are fully in line with the "Grow & Impact" strategic plan, which aims to reinforce Saint-Gobain's positioning as the worldwide leader in light and sustainable construction and to offer its customers comprehensive solutions that deliver sustainability and performance. In France, Saint-Gobain is the leader in the energy renovation market thanks to its ISOVER, Placo^®, Saint-Gobain Glass, Weber brands and its strong distribution network.

The Group has a unique and dense presence across the entire value chain in France: from the manufacture of sustainable solutions to their distribution - in stores offering advice, training, digital services, and logistics or recycling solutions to our hundreds of thousands of trade professional customers, as well as on e-commerce platforms or our site offering inspiration and intermediation, La Maison Saint-Gobain. Worldwide, the solutions sold by the Group in one year avoid the emission of approximately 1,300 million tons of CO₂ during their lifetime, which is more than 40 times the Group's total carbon footprint.
