E-A-R's barrier composites provide weight- and thickness-efficient noise control for demanding environments by combining TUFCOTE® lead-free vinyl or urethane barrier materials with proprietary acoustical or damping foams. A variety of facings, as well as edge-sealing, increase durability, resistance to dirt and moisture. PSA backings are available, too.
