This Environmental Product Declaration (EPD) describes the environmental impacts of 1m² glass wool insulation, thickness 25 and 25 mm and R-value 0.78 and 0.78 m2·K/W. Insulation with mineral wool (glass wool) is used in buildings and in industrial installations. It ensures a high level of comfort, reduces energy costs, reduces carbon dioxide emissions (CO2), prevents heat loss through sloping roofs, walls, ceilings, pipes, and boilers, reduces sound pollution and protects houses and industrial installations from risk of fire.
