SAINT-GOBAIN LAUNCHES IN FINLAND ITS LOWEST CARBON
GLASS WOOL INSULATION PLANT IN THE WORLD

Saint-Gobain announces the launch of very low-carbon (scope 1 & 2) glass wool production at its
Isover plant in Forssa, Finland.
The Forssa plant is now powered exclusively by decarbonized energy thanks to the installation of 3
pressurized biogas tanks. This new equipment completes a biogas supply by pipeline directly
connected to a local producer, in operation since 2010. Biogas now accounts for 50% of the energy
used by the site, with the remaining 50% supplied by hydroelectric power.
This modernization of existing infrastructure illustrates the Group's commitment to efficient, low-
carbon transformation, via targeted investment and ongoing optimization of operations.
The new equipment will prevent the emission of 1,500 tonnes of CO₂ per year.
On average, the products’ carbon footprint will be reduced by 30% to 40%1 over its whole-life cycle
compared to equivalent products currently produced using different energy mixes.
These developments strengthen the Group’s leadership in light construction in Finland, while
meeting strong demand for efficient and sustainable solutions that enhance occupant comfort and
reduce the carbon footprint of buildings.
Saint-Gobain has a long-standing commitment in Finland to reducing the environmental footprint of
its new construction and renovation solutions. The glass wool produced by Saint-Gobain in Finland
contains up to 80% recycled glass, making the company the largest user of recycled glass in the
country.
This new achievement is a concrete illustration of Saint-Gobain’s ambition to reach net zero carbon
emissions by 2050.
