A sedan trunk can create its own drum due to the vibration from tires. The heat and drone from the exhaust can make the car unbearable to drive. If you are ready to make your vehicle sound great on the outside but quieter, cooler to ride on the inside, then HushMat sound deadening and thermal auto insulation is your answer. Your vehicle will turn heads with its power, performance and style. When you drive on the highway at approximately 65 miles per hour the interior of your vehicle is approaching 80 decibels. That is like a vacuum cleaner or garbage disposal running on your passenger seat. HushMat automotive sound deadening is the solution to REDUCE the noise level in your car by up to 15 decibels. When you drive on the highway and then exit, the first thing you do is 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 car audio sound deadening reduces this noise floor and allows you to hear more music. HushMat sound deadening and thermal insulation material leads the automotive industry in ease of installation. It is also number 1 Rated in performance. Packaged specifically for your trunk to provide 100 percent insulation coverage, there are no holes in the material and no puzzle pieces to put together. Simply apply the HushMat Ultra material as shown in the Installation Guide. HushMat auto insulation material reduces road noise, exhausts noise, and insulates your vehicle for a more comfortable ride for you and your passengers. Nothing beats the heat or noise like HushMat. HushMat has been manufactured in the USA for three decades.

HUSHMAT ULTRA is a pressure-sensitive, constrained-layer damper, which has excellent adhesion to many difficult to bond substrates such as oily cold rolled steel, aluminum, steel, fiberglass, automotive coated surfaces, and many plastics including polypropylene. The aluminum foil constraining layer and specially formulated viscoelastic polymer layer combine to give effective vibration damping over a wide temperature range. Ultra is provided in rectangular or square sheets and can be hand-cut for special configurations.
HUSHMAT ULTRA is temperature resistant and will maintain adhesion through all automotive bake cycles including 288°C (550 degrees F) over-bake conditions. This allows its application at any stage of the production cycle. It can be applied to both pre-painted and top-coated metal surfaces. It is compatible with automotive coatings and will not contaminate spray operations. HUSHMAT ULTRA superior adhesion characteristics provide excellent corrosion resistance.
The superior adhesive properties of HUSHMAT ULTRA allow it to be used in horizontal, vertical or inverted applications. It has good conformability and can be applied on complex shapes.HUSHMAT ULTRA is approved for many automotive specifications. Contact your Hushmat representative for details, and for design and custom application assistance.

Damping is the physics that converts vibration energy into heat. The HushMat Ultra is formulated to dissipate (reduce) this energy and absorb it into the material at any temperature below 550 degrees F (288C). This dramatically reduces the vibration energy and the noise that comes from it. Damping is primarily a mass over area physical science and damping materials characteristics are relevant in three primary areas:
- Adhesion –
HushMat is superior in all three areas when compared to the other brands. HushMat provides superior adhesion across the broad temperature spectrum from -30 to 550 degrees F. HushMat is significantly more flexible than competitive brands, even in freezing temperatures, and no heat guns are needed nor special tools to install it. All you need is a pair of hands and a pair of scissors. HushMat is thinner. However it is slightly higher weight per square foot than the closest competitor. HushMat contains no plastic or asphalt fillers, therefore, you do not have to double layer the application. HushMat is also manufactured in the USA!
Street rods, hot rods and muscle cars and your daily driver vehicle have significant heat that penetrates through the firewall, tunnel and roof. There are several areas on a vehicle interior that experience above average temperatures. The firewall, the tunnel, near the header, above the exhaust, sun light pounding on the roof to name a few. HushMat Ultra comes in dimensions that offer excellent thermal properties. The 1.5mm & 0.47 pounds per square foot compound blended butyl rubber and foil laminate construction provide an excellent treatment for these difficult application areas.
For extra thermal protection apply ½” Silencer Megabond directly on top of HushMat Ultra on the firewall, tunnel and trunk floor for optimum thermal insulating performance. Apply ¼” Silencer Megabond to the back of the headliner for extra insulation from the radiant heat. Call or e-mail us and we can provide you with the best material for these applications. HushMat Ultra is specified to perform at up to 550 degrees F. HushMat Ultra II Hoodliner can also be applied to the engine side of the firewall, hood and front quarter panels.
HushMat Silencer foam should be applied to the following areas:
- ¼” back of door trim panels with foam facing outer skin of door
- ½” under carpet adhered to HushMat Ultra on dash and floor,
- ½” or ¼” under trunk fabric adhered to resin layer of trunk fabric, and rear wheel wells,
- ¼” above the headliner adhered to fiber board of headliner,
- 1/8” on the back of all loose plastic trim or anywhere that plastic and metal rub together and create that annoying squeak and rattle.
