EPD: EPS insulation board, L= 0.033 W/mK, 30 kg/m3, 600 x 1200mm, Lambda=0.034 W/(m.K), Jackofoam (BEWI ASA, Insulation and Construction)
The insulation board is provided in several dimensions and thicknesses. Extruded polystyrene (XPS) is a common material used for thermal insulation of buildings and constructions. Its a polymer foam, consisting of airfilled polystyrene cells. As most of the material is air, XPS provides good insulating properties at a low weight. Other characteristics of the material include low moisture absorption, long service life and high compressive strength. This LCA is based on Jackofoam 300 and can be used for all Jackofoam products with the conversion factor which can be found under System boundaries Product specification XPS is manufactured through an extruder where polystyrene granulates are mixed with additives and foaming agents to produce the foam mass. The foam mass is pressed out flat to a board through a nozzle in deisre thickness and cut into correct dimensions. Some of the remaining blowing agents are aired out before the product leaves the factory gate.
