Damplifier Sound Deadening Mat

Damplifier sound deadening mats were designed to be the highest performing sound dampening material relative to weight added to a vehicle. With premium butyl rubber, a thicker foil constraint layer, and comparable overall thickness to other top brands’ flagship product, Damplifier premium butyl mats are the best value on the market. 



  • High temperature butyl rubber adhesive – insist on more rubber and less filler!
  • Ultra-thick, annealed black foil with a ghosted logo
  • 1mm total thickness (40 mils)
  • Each sheet is 12” x 24” (2 sq ft) and weighs about 0.35 lbs / sq ft
  • Thermal range: -75 F to 450 F – will not melt, out gas, or fall off
  • NEVER USES cheap filler materials, asphalt, flimsy foil, and other shortcuts that hurt product performance
  • Guaranteed adhesion to metal for the LIFE of your vehicle
  • Proudly made in the USA

Installation Instructions 

  1. Remove plastic panels, upholstery, and insulation to expose bare sheet metal.
  2. Remove debris, rust, and waxy oils. Clean surface with denatured alcohol (NOT a degreaser).
  3. Cut sound deadening material using a utility knife - either freehand or using a template. We recommend wearing gloves.
  4. Remove wax paper backing. Stick tacky butyl adhesive to metal surface. 
  5. Use a Wooden Hand Roller to roll out any air pockets and create a permanent bond. A better bond further increases performance.
  6. Combine with a second layer like Luxury Liner Pro for unmatched car sound proofing. Luxury Liner Pro is our best automotive mlv car noise barrier.
