Dampwall is a panel of ribbed rubber with a density of 720kg/m³, which is fixed to a plasterboard and designed to be laid on existing walls as dry lining in order to improve sound insulation. The use of a polymer binder with very high elasticity and the innovative ribbed finish on one side of the panel allow a high degree of sound insulation which is guaranteed over time. The ribbed finish also ensures greater adhesion to the wall.
