This premium butyl material with aluminum top layer provides extreme vibration damping and effective sound deadening for demanding automotive, commercial, and competition-level applications. Interior panels naturally vibrate and generate noise β€” Boom Mat deadens and dampens those sounds by trapping vibration energy and stopping it before it enters the cabin. Unlike asphalt-based alternatives, 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 you’re upgrading a daily driver or prepping a competition vehicle, Boom Mat XL delivers the performance you need. Review: Greatly Reduced the Vibration - I bought new speakers for my car and kept hearing a rattling/vibration noise wherever their was heavy bass in the song. so i looked up how to reduce it and found these and they work Great. I did the whole rear deck and half of the inside of the front doors. it also reduce some of the noise from outside so now I got quieter ride. Review: Deadens the sound like a dream - This stuff is a little speedy but totally worth it in the end. I have two 12” subs in the cab of my truck and from the outside with the stereo blasting you can barely hear it. Stops almost all rattles, some plastic body panels still make noise but nothing I can do about that. Totally worth the investment. ## Features - Covers 20. 8 sq. ft. - Ideal for car, truck, and even boat interiors.

Totally worth the investment. ### ⭐⭐⭐⭐⭐ Great mat but pricey. *by Z***N on April 28, 2021* Thickest butyl deadnening mat if seen so far. Good quality with good adhesion. Not sure if the extra thickness is worth the extra cost tho. But if money isn’t an issue I would recommend trying this over other brands. --- ## Why Shop on Desertcart? - πŸ›’ **Trusted by 1.3+ Million Shoppers** β€” Serving international shoppers since 2016 - 🌍 **Shop Globally** β€” Access 737+ million products across 21 categories - πŸ’° **No Hidden Fees** β€” All customs, duties, and taxes included in the price - πŸ”„ **15-Day Free Returns** β€” Hassle-free returns (30 days for PRO members) - πŸ”’ **Secure Payments** β€” Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** β€” Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.co.za/products/93176643-design-engineering-boom-mat-xl-4mm-sound-deadening-damping-material](https://www.desertcart.co.za/products/93176643-design-engineering-boom-mat-xl-4mm-sound-deadening-damping-material) --- *Product available on Desertcart South Africa* *Store origin: ZA* *Last updated: 2026-06-06*
