HushMat’s sound deadening and thermal insulation enhances the experience with the easiest to install sound deadening material.  Your vehicle is fun to drive. but the engine gets hot. Your engine. headers. manifold. and exhaust generate tremendous heat that transfers to the metal firewall and floor and this heats up your vehicle interior. It can create a very uncomfortable ride. especially in the summer. This also forces your AC system to work harder to reduce and maintain comfortable temperatures inside your vehicle. HushMat automotive insulation is the solution to REDUCE thermal transfer into your interior. HushMat is proven in an independent study to lower this temperature by over 40 percent. Nothing beats the heat and noise like HushMat. Your vehicle is known for its style. performance. and power. It will turn heads. but what about the sound insulation? When you drive on the highway at approximately 65 miles per hour the interior of your vehicle is approaching 80 to 90 decibels of noise.
