SOUND-DAMPING OR SOUND-PROOFING MATERIAL, AND A METHOD OF ADHERING THE MATERIAL TO A SUBSTRATE

摘要

A bitumen-based, panel- or web-shaped sound-damping or sound-proofing material is adhered to a substrate by heating, a corona-treated polyolefin film being placed between the substrate and the material. The adhesion of the material to the substrate is improved by corona-treating at least the free surface of the polyolefin film facing the substrate.
