Sound insulation DUCORK Rubber
DUCORK Rubber is a high-quality sheet soundproofing material made from natural cork granules bonded together with synthetic rubber. It is produced in a multi-stage process, in which natural cork is combined with rubber granules under the influence of a PU binder. Due to its composition, DUCORK Rubber is characterized by good resistance to both acids and atmospheric influences, as well as abrasion. The material has high density and mechanical resistance, which allow the isolation of airborne and impact noise. For this reason, DUCORK Rubber is also used as a vibration-isolating sealing material. Another advantage is the compressive strength and dimensional stability of the material.
Application:
soundproofing of walls, floors and ceilings
compensates for uneven floors and can be used as an underlay for almost all floors
