Title: ROCKWOOL isolering - NEPD nr_ 00131E rev1(EPD).pdf
Description of manufacturing processes: The furnace used in all four production sites is an oven with coke as the main energy source. The virgin stone raw materials used at all sites are mainly basalt, diabase and dolomite. The Danish sites also use various secondary materials, including internal wool waste, which is mixed with cement into briquettes. The mineral raw materials are melted and spun into fibers at a temperature of about 1500⁰C. A synthetic binder and a water-repellant agent are added, whereafter the final curing (polymerisation) and forming takes place at a temperature of about 230⁰C. Finally the product is cut into the desired dimensions and packed in PE foil.Market: ScandinaviaReference service life: The service life of the product is >> 60 years and built into a construction and will last the construction lifetime.Product specification: Material input per functional unit Material Stones Secondary resources mostly slag Cement Formaldehyde (37%) Urea (46%) Phenol
