Ever think about driving on the highway and then exiting? At the end of the exit ramp what is the 1st thing you do? You turn down your radio or music because it was too loud! It had to be that loud on the highway to over come all the noise inside your vehicle. HushMat reduces this noise floor and allows you to hear more music.

Did you also know there is over 200 degrees of heat cooking your firewall and floor pan? That's right - your engine, headers, manifold & exhaust generate tremendous heat that transfers to the metal firewall & floor - this heats up your vehicle interior. This creates a very uncomfortable ride, especially in the summer! This also forces your AC system to work harder to reduce & maintain comfortable temperatures inside your vehicle. HushMat is the solution to reduce thermal transfer into your interior. HushMat's proprietary USA manufactured visco-elastic chemistry dissipates this heat insulating your interior causing less load on your A/C system - making your vehicle significantly cooler. HushMat Ultra is proven in an independent study to lower this temperature by over 40%.
