Dynamat TacMat.

TacMat takes a scientific approach to conquer two enemies that destroy your driving pleasure: noise and heat. The same technology used in aerospace materials gives TacMat a higher insulating value than fiberglass and sound-reducing capability greater than other materials ten times its weight. A thermo-acoustic cockpit liner, TacMat is approved by DOT FMVSS 302 and passes Federal Aviation Regulations. TacMat uses a unique conversion process that limits the volume and duration of any structure-borne noise within your vehicle's interior.

Contains one 32" x 54" piece of TacMat for roofs, floors, behind trim panels, inside speaker enclosures and inside door pillars.

Contents: (1) 32" x 54" x 0.25" (813mm x 1372mm x 6mm) piece of Dynaliner

Application: Use on roofs, floors, behind trim panels, inside speaker enclosures and inside door pillars to insulate against heat and to maximize sound absorption. For high heat areas, use Extremeliner over Dynamat instead of TacMat.
