DEI Boom Mat Damping Tape - Universal, 1.5 in x 20 ft - Silver

Boom Mat Silver Damping Tape is 2.5 mm butyl rubber with a bright aluminum face and a peel and stick adhesive under a clear release liner. Added to a panel it damps the resonance that turns road and drivetrain vibration into cabin noise, and it seals seams and small gaps as it goes. The roll runs 1.5 in wide by 20 ft long and covers 2.5 sq ft, a width that drops neatly into van floor ribs and truck bed channels. It cuts with scissors and bonds to metal, aluminum, fiberglass, plastic, foam padding, and many fabrics.
