Abstract:
The invention relates to vibration damping wall material or wall covering material. The material is comprised of a laminate which includes two thin metal sheets and a solid rubber layer sandwiched therebetween. The rubber layer has the form of a rubber foil or rubber film having a thickness of 0.08-0.30 mm and produced by carrier calendaring and is vulcanized to each metal sheet. The metal sheets suitably have a thickness of 0.2-0.7 mm. The rubber layer is conveniently formed from an electrically conductive rubber mixture.
