The DEI Boom Mat XL Vibration Damping Material is a premium, high-performance sound deadening solution designed for serious noise control in vehicles, boats, RVs, and commercial applications.
This 4mm thick, asphalt-free butyl rubber damping material features a thick 4-mil aluminum constraining layer that dramatically reduces vibrations, road noise, and panel resonance.
Unlike cheaper damping materials, Boom Mat XL requires only 25β50% surface coverage to achieve excellent results, saving weight, time, and money. Its superior adhesion works on vertical and overhead surfaces, even in extreme temperatures, making it the go-to choice for audio enthusiasts, custom car builders, and anyone seeking a quiet, comfortable interior.
