Boom Mat XL 4mm Sound Deadening and Vibration Damping Material offers a quieter, more comfortable ride with Boom Mat XL.

This butyl material with aluminum top layer provides effective sound deadening and extreme vibration damping for automotive, commercial, and competition-level applications.

Interior panels vibrate and generate noise — Boom Mat dampens and deadens those sounds by trapping vibration energy and stopping it before it enters the cabin.

Unlike alternatives based on asphalt, Boom Mat uses pure butyl for superior adhesion, even on vertical and overhead surfaces in extreme temperatures.

With only 25–50% coverage required, you’ll save weight, material, and installation time while achieving professional-grade noise reduction.

Whether upgrading a daily driver or prepping a competition vehicle, Boom Mat XL delivers the performance needed.
