Title: ROCKWOOL isolering - NEPD nr_ 00131E rev1(EPD).pdf
LCA: Calculation rules Declared unit: 1 m2 of 37 mm thick stone wool insulation product with a density of 29 kg/m3 and a thermal resistance of R=1 m2 K/W .System boundary: The overall system boundaries include extraction and transportation of raw materials as well as all manufacturing processes (cradle-to-gate). Transport from all factories to a central storage in Norway has been included. See Figure below for detailsData quality: High quality data from GaBi 6 and ecoinvent have been used for acquisition of raw materials and transportation. Legally required information has been used for manufacturing processes at ROCKW OOL. The age of the oldest dataset in the database is 13 years and the vast majority of datasets are under 5 years old. The data collected from the sites are from 2011. Accordingly, the overall quality is judged to be good to very good.
