Enjoy a Quieter, More Comfortable Drive for The Long Haul in Your Ride

You may have noticed a difference in comfort and noise levels between your hot rod or classic car and your daily driver (or perhaps it was your significant other who mentioned it!). Today, even pickup trucks are laden with all manner of sound control products and vehicle acoustic insulation. Spray in sound deadening material on metal surfaces, extra backing material on door panels and firewalls, and more to keep road noise, engine noise, and wind noise at bay. A quieter car provides better road comfort, lower decibel levels for conversation or music enjoyment, and more. Adding car audio sound deadening material or road noise reduction products to make for a quieter ride, be it to a local cruise night or to drive across the country on a road trip of a lifetime, shouldn’t take a degree in acoustic management. That’s why we’ve developed UnderTone Dampening™ products to make sound control simpler at a great value.

We believe effective road noise reduction inside your vehicle doesn't require complicated product selection, excessive material coverage, or premium pricing to be a real solution. Instead, great sound dampening comes from the best automotive sound deadening material used in the product itself and strategic installation in high vibration areas. UnderTone Dampening™ delivers professional-grade vibration damping and noise reduction in an easy-to-install “peel and stick” solution that helps enthusiasts build a quieter, more enjoyable ride without overspending on product or overcomplicating the job by requiring full coverage. Whether you need car or truck sound deadening solutions, UnderTone Dampening™ products is your top solution.

An Easy to Install Butyl Based Dampening Product That Delivers Real World Results

Unlike spray on sound deadener for cars and trucks, which requires massive disassembly, masking, and prep to apply, UnderTone Dampening™ sound dampening sheets are applied where necessary. This avoids the “shotgun” approach of spray on sound control products. Each 14” x 10.2” sheet of sound deadening material features a three-layer construction design engineered to improve cabin comfort. A durable 4 mil aluminum foil facing helps reflect heat and strengthens the material, while the butyl rubber core absorbs vibration and reduces panel resonance. A strong self-adhesive backing allows for fast, secure installation on virtually any clean surface. Together, these layers create an effective barrier against noise while helping reduce heat transfer into the vehicle's interior and are ultimately way more effective at reducing sound levels and thermal transfer than anything the factory used in your hot rod, muscle car, or classic pickup back in the day.

The Coverage You Need, Where You Need It, Without the Waste or Extra Weight

The flexible 2mm overall thickness of the UnderTone Dampening™ material easily conforms to curved panels, corners, and stamped sheet metal, making it ideal for doors, floors, trunks, roofs, firewalls, and interior panels. This allows you to target vibration prone areas of your vehicle without the need or expense of full coverage, which also means less product square footage to purchase and less overall installation weight. Whether you're completing a full restoration or simply targeting problem areas, installation is straightforward on any clean, solid surface. Just peel, apply, and roll for maximum adhesion and performance. Our professional grade sound dampening product provides pro level results with an easy to install solution without the need for high dollar shop installation costs.

UnderTone Dampening™ products deliver an ideal balance of performance, value, and ease of installation, making it a smart choice for first timers and experienced builders alike. Each box of 2mm thick dampening product covers approximately 20 square feet and comes in 20 pre-cut sound dampening sheets ready for installation on any solid surface (metal, wood, or plastic). Whether you’re looking to improve your sound system, lower interior decibels for quieter conversations, or simply looking to make the closing of your car’s door sound more solid and upscale, the use of UnderTone Dampening™ sheets in strategic areas will provide professional results at a practical price point. We believe this is the best automotive sound deadening material you will find for the value.
