DEI Boom Mat XL Vibration Damping Material - 12.5in x 24in x 4mm (Set of 2)

DEI Boom Mat XL Vibration Damping Material is an extreme-duty solution engineered to eliminate structural vibration and mechanical noise in demanding commercial and sound competition environments. This 4mm thick material utilizes a high-mass, asphalt-free pure butyl layer to constrain noise, bonded to a 4 mil aluminum stiffening top skin that prevents interior panels from generating resonant frequencies.

Designed for efficiency, Boom Mat XL provides significant damping with only 25-50% surface coverage, which minimizes added vehicle weight and installation time. The high-tack adhesive is formulated for a permanent, no-sag bond on vertical and overhead surfaces even in extreme temperature ranges. This material serves as a critical first layer for any sound-deadening project, significantly improving stereo clarity and cabin comfort.
