Fremgangsmåde til fremstilling af isoleringsmateriale, organisk fibermateriale og blæseisoleringsfremgangsmåde til udförelse af isolering

摘要

A method of producing an insulation material, the method comprising fiberizing a wood material or another fiberizable material in the manufacturing process of pulp, performing washing and drying, said insulation material being refiberized later so as to provide it with a larger volume. The method is characterized in that an adhesive is added to the insulation material after the washing step but before the refiberization to be performed later so as to provide the insulation material with a larger volume.
