Absorb and eliminate high frequency airborne noise that enters the vehicle interior through the air. Sound deadening pads treat structural vibration - noise in a frequency range from zero to 1,000 Hz. Silencer Megabond absorbs airborne high frequency noise up to 4000 Hz frequency. Engine, exhaust drone, road noise and wind noise is well above 1,000 Hz. This noise disrupts your ride and reduce the heat that comes from engine, headers, exhaust and catalytic converter - with one USA Made material - lightweight & self-adhesive HushMat Silencer Megabond. Similar to the application of foam on the ceiling and walls of a recording studio - HushMat's Silencer Megabond performs a similar function in the interior of vehicles.

When driving your vehicle do you feel the heat coming through the firewall, floor & tunnel? Do you hear the road noise and vibration that prevents you from having a phone conversation? - does it drive you crazy? Do you wish you could stop the heat and the noise and enjoy a current model quiet ride on the inside? HushMat is the solution.

Did you know when driving on the highway at 65-70 miles per hour the interior of your vehicle is approaching 80-90 decibels? That is like have a vacuum cleaner or garbage disposal running on your passenger seat! Sounds crazy right? This happens in most vehicles every day. HushMat is the solution to REDUCE the noise level in your vehicle by up to 15 decibels!

Ever think about driving on the highway and then exiting? At the end of the exit ramp what is the first 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 overcome 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. The combination of HushMat's proprietary USA manufactured visco-elastic Ultra chemistry and the application of HushMat's Silencer Megabond foam dissipates this heat insulating your interior causing less load on you're A/C system - making your vehicle significantly cooler. HushMat's combined treatment is proven in an independent study to lower the thermal transfer into the vehicle interior by over 70%.

HushMat is the only OEM specified and approved sound deadening & thermal insulating material available to the automotive aftermarket.
