A polyethylene insulation roll with a density of 90 kg/m³, featuring a cross-linked and amorphous cell structure. The HPE Series has a high-density, cross-linked amorphous cell structure, which prevents the transmission of sound and heat. Manufactured in a rubber-like form through baking, it offers much higher mechanical strength compared to standard PE products. The HPE series is used for insulating both airborne and impact noise between spaces, while also providing high thermal insulation performance.
