The 911 trunk is cavernous and constructed in sheet metal. The trunk generates a drum effect and noise that can enter the interior. The HushMat trunk kit is designed to eliminate this drum effect and keep the interior quiet. The HushMat trunk kit is enough material to sound deaden the trunk floor, front wheel wells and trunk lid.

Hushmat Ultra Vibration Damping Properties Graph
Easier Installation + Better performance = GREAT VALUE!
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.
