This EPD includes the following EPS insulation products: EPS 60, EPS 80, EPS-G80, EPS 100, EPS 150, EPS 200. EPS 80 has been selected as the representative product, as it represents the largest production volume. The included products have different thickness, density and thermal conductivity [W/mK]. The type of raw material used is the same for all included products. Expanded polystyrene (EPS) is widely used as a thermal insulation material in buildings, including applications in floors, walls, and roofs. It is a lightweight polymer foam made up of air-filled polystyrene cells. Since approximately 98% of EPS consists of air, it offers excellent insulation performance while remaining light in weight. Additional benefits of EPS include minimal moisture absorption, durability, high compressive strength, and full recyclability. The density of the block is determined by the amount of EPS used in the mold. For example, EPS80 corresponds to a compressive strength of 80 kPa. This LCA study includes the provision of all materials, transportation, energy and emission flows, and end of life processing of product. All industrial processes from raw material acquisition and pre-processing, production, product distribution and installation and end-of-life management are included. The production of capital equipment, construction activities, and infrastructure, maintenance and operation of capital equipment, personnel-related activities, energy and water use related to company management and sales activities are excluded.
