This Environmental Product Declaration (EPD) describes the environmental impacts of 1m² extruded polystyrene insulation, thickness 40, 50, 60, 70, 80, 100 and 120 mm and R-value 1.20, 1.50, 1.80, 2.00, 2.25, 2.85 and 3.35 m2·K/W respectively.URSA manufactures extruded polystyrene (XPS) with recycled materials (polystyrene). The products obtained are presented in the form of an extruded polystyrene panel composed of a rigid structure and air.On Earth, the best insulator is dry and still air at 10 °C: its coefficient of thermal conductivity, expressed in lambda (λ), is 0.025 W/(m.K) (watts per meter and per degree Kelvin). The thermal conductivity of extruded polystyrene is close to that of air at rest since its lambda varies from 0.029 W/(m.K) for the most efficient, to 0.037 W/(m.K) for the least efficient.Thanks to its alveolar plastic foam structure, extruded polystyrene is a material that traps air, making it a solution for insulation. In addition, extruded polystyrene has a high level of mechanical compressive strength, which makes it suitable for certain specific applications: underfloor heating, floors, flat roofs, insulation on the outside of buried walls and under foundations.Extruded polystyrene insulation is used in buildings and in industrial installations. It ensures a high level of comfort, reduces energy costs, minimizes carbon dioxide (CO2) emissions and limits heat loss through ceilings, walls, floors, pipes and boilers.
