This Environmental Product Declaration (EPD) for the Gedina product family describes the environmental impact of 1m² of acoustic ceiling with the intended use to increase sound absorption in a room to create a better indoor environment. The scope for this EPD is cradle-to-grave.The production site of Saint-Gobain Ecophon (Sweden) produces acoustic ceilings and wall absorbers based on glass wool with a plant based binder in different densities and thicknesses. The glass wool is covered with a painted or woven surface layer and cut into panels of different sizes and edge designs.Acoustic panels made of glass wool are commonly used in schools, offices, health care facilities and production premises where there is a need for noise reduction to improve the working environment. The decrease in reverberation time, sound pressure level and other acoustic parameters are related to the amount of panels used in the room as well as the placement of the panels.
