EPD: XPS Insulation board, L= 0.033 , R=1 m2K/W, 33 mm, 600 x 1200 mm, 1.42 kg/m2, 42.9 kg/m3, Sundolitt XPS700 (Brødr. Sunde AS)
The insulation board is provided in several dimensions and thicknesses. Please use the conversion table below for other sizes than the declared unit. The declared product is manufactured at a single production at Skedsmo. Specific data was collected for this site. No averaging has therefore been performed. Extruded polystyrene (XPS) is a common material used for thermal insulation of buildings, and constructions. This includes protection against frost blistering and frost penetration for buildings, road, railway etc. It is a polymer foam, consisting of air-filled 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. XPS is manufactured through an extruder where polystyrene (GPPS and EPS) granulates are mixed with additives and foaming agents to produce the foam mass. The foam mass is pressed out flat to a block which is cut in desired dimensions. Some of the remaining blowing agents are aired out before the product leaves the factory gate. The amount of raw material going into the product determines the density of the block. This LCA is based on pressure class 300, which provides a density at approximately 33 kg/m3 of insulation. Weight per declared unit is approximately 1,089 kg given a density of 33 kg/cubic meter with a thickness of 33 mm.
