SOUNDPROOFING TECHNICAL INFO

ACCORUB® is an acoustic mat, produced from foamed rubber granules that are bonded with a high-quality polyurethane based adhesive. Additives added to the system optimise the acoustic and mechanical properties. Due to the specific open-celled structure of the granules, very good acoustic properties are obtained. ACCORUB® acoustic mats exist in different thicknesses (10 to 150 mm) with densities starting at 120 kg/m3.
