LETTER TO SHAREHOLDERS N°96

A LAB-TESTED ZERO-CARBON HOME In the UK, Saint-Gobain was involved in building eHome2, a house capable of operating without emitting CO2. Under this unique project, the different parts were first assembled in the factory before being delivered on-site, saving both time and money. eHome2 was also tested under extreme laboratory conditions for nine months to measure its performance (in all weather conditions – rain, snow, wind), with temperatures ranging from -20°C to +40°C). This test will allow Saint-Gobain and Barratt Homes to reinforce their understanding and expertise in building zero-carbon prefabricated housing at scale and developing light and sustainable construction solutions. INNOVATION For the second year in a row, SaintGobain Distribution Bâtiment France took part in the EcoVadis questionnaire, an external platform for assessing Corporate Social Responsibility (CSR). Large companies, by having their sustainability commitment recognized, are at the same time pushing their business partners to go beyond mere compliance. A virtuous and transparent approach based on a questionnaire covering the main CSR themes, divided into four parts: social issues and human rights; the environment; responsible purchases; and ethics. Questions are adapted to the industry sector and scale of each participant. The result: a gold medal for SaintGobain that demonstrates the value of our collective commitment and that enables Saint-Gobain to demonstrate its CSR commitments and progress in 2022. BUILDINGWITH EARTH Saint-Gobain is bringing excavated earth back into fashion with the launch in France of its “Construire en Terre” (Build in Earth) program. This age-old material is ideal for constructing buildings capable of offering greater comfort in both summer and winter, as well as greater humidity regulation and sound insulation. These performances are derived from traditional construction methods, which are highly sought-after to adapt modern construction to rising global temperatures. By combining its research forces, its industrial capacities and its Point.P materials distribution network, Saint-Gobain has developed several processes for using excavated earth in construction: from production of the binding earth mixture, non-structural earth concrete formwork(1) set in a wood or concrete frame and a mix of earth, biosourced plant fiber and a patented low-carbon hydraulic binder, produced on site and projected directly into a woodframe building; to new training programs for trade professionals and assistance on their first earth construction site. This solution complements the know-how of trade professionals and is designed for the traditional building industry. MARKETS AND CUSTOMERS MARKETS AND CUSTOMERS MARKETS AND CUSTOMERS BRAZIL AND EGYPT: THE ALCHEMY OF SUCCESS By successively integrating Chryso in 2021 and GCP in 2022, Saint-Gobain has become one of the world leaders in construction chemicals. With the acquisition of Matchem in Brazil and IDP Chemicals in Egypt, the Group is activating a new lever in its strategy of conquest: taking strong positions in markets with strong potential for growth, synergies and value creation, in line with its “Grow & Impact” strategy. In Brazil, its strengths are added to those of Quartzolit, the local branch of Weber, leader in mortars; TekBond, sealant and adhesive specialist; and the recently acquired GCP, allowing Saint-Gobain to offer its customers tailor-made solutions and optimized logistics. (1) Formwork is primarily used to shutter the concrete walls (generally reinforced); this is then known as shuttered concrete.
