FAQs

HushMat is and always has been 100% manufactured in the United States of America.
The only difference is the black ink applied to the aluminum foil to provide a non-reflective surface. Both Silver and Black Ultra perform identical in all testing.
HushMat has taken the guess work out of this question through the development of custom vehicle kits. We have 300,000+kits for most sedans, light trucks, vans and semi-trucks pre-sized to fit each vehicle. Visit our Make, Model & Year look up for the HushMat kit made for your vehicle.

Yes we do. We have extensive experience in all forms of transportation vehicles including RV’s. You will need one product to treat road noise – HushMat Ultra. We recommend application of HushMat to the firewall, doghouse, front driver & passenger floor to reduce road and tire noise. If is road noise from the rear tires that concerns you – you will need to cover the rear wheel well housings with HushMat Ultra.
Noise enters the interior of any vehicle in two ways – It is enters through the structure or chassis of the vehicle and all parts connected to it. This is Low Frequency Noise in the range of 0-1000 Hz. This noise source requires vibration damping material aka sound deadening – HushMat Ultra. We recommend for effective reduction of structural transmitted noise to cover 60% of the metal panels surrounding the interior i.e. firewall, floor, roof, doors, truck, rear quarter panels, trunk floor and trunk lid. You would apply Ultra to these panels beginning in the center of the panel and work toward the outer edges again covering at least 60% of the panels surface. The second way noise enters a vehicle interior is from the outside – in through the air. We call this airborne noise. It’s sources are road & tire, wind, exhaust drone and engine noise. You can double and triple layer HushMat Ultra but you are not going to address these sources of noise. This is High Frequency Noise > than 1000 Hz frequency. This noise must be absorbed. Silencer Megabond is a blend of synthetic rubbers formulated for optimum sound wave absorption in automotive and marine environments. Silencer Megabond is a semi-closed cell foam that absorbs sound waves up to 4000 Hz frequency. The combination of HushMat Ultra and Silencer Megabond offers you the optimum performance to quiet any vehicle on the road today.

HushMat Hoodliner material is specifically manufactured for “Under the Hood” or “Engine Side” applications. HushMat Hoodliner material is robust at 2.0mm thickness and will insulate your vehicles hood (bonnet) from the high engine temperatures. HushMat Hoodliner comes in 12 Square Feet Kits and is universal to every vehicle on the road today. HushMat Hoodliner is also paintable.
No, this another consumer friendly attribute of HushMat versus other companies products. There is no odor with HushMat. HushMat does not product any odor even in the world’s hottest and most humid climates. HushMat has no plastic or asphalt fillers that tend to create these odors.
The only prep we recommend is lightly dampen a cotton cloth with water (not dripping) and rub over the surface to remove dust or dirt. (WE DO NOT RECOMMEND USING SOLVENTS, ACETONE OR ALCOHOL BASED CLEANERS.) Allow the area to dry to the touch – then peel and stick HushMat.
Effective treatment for heat is to cover 100% of the surface area of the vehicle. Any void – even 5% will allow a majority of the thermal transfer into the interior of the vehicle. You will get both outstanding heat and sound reduction one HushMat material.
It is very simple – please send us an email with your name, store name (owners name if different), type of business you are in (Hot Rod shop, speed shop, car audio retail, collision repair, upholstery, Tint shop, Restyling center to mention a few) and email it to sales@hushmat.com or call our office M-F 8:30AM – 5PM Central Time.

HushMat Ultra is a compounded blend of butyl rubbers formulated specifically for low, room and high temperature properties. HushMat is thinner but offers significantly higher density that competing products. This product advantage allows us to provide a product that is significantly more flexible and easier to work with material that offers you dramatically higher performance.
HushMat Ultra’s proprietary formula is the adhesive. HushMat’s formulation requires no glues or film adhesives like other brands. HushMat Ultra has passed over 25 years of rigorous in-vehicle validation of performance in every climate on the globe. If you slice the Ultra compound you will see that both sides of the slice are tacky. This is one of the competitive advantages of HushMat.
Once you adhere a sheet of HushMat Ultra to a surface you have 2-3 minutes of time to pull the sheet back and re-apply it. After 3 minutes the molecular bond begins and you will have difficulty removing the material. HushMat Ultra is made to stay adhered to your vehicle for its entire useful life. Even in overhead or vertical surfaces in the hottest of climates – HushMat stays bonded to the vehicle.
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. The key product characteristics of damping materials are:

Adhesion –
Conformance/Flexibility
Weight/Mass

HushMat leads the industry in performance. HushMat provides superior adhesion from -30 to 550 degrees F. HushMat is more flexible than competitive brands, even in freezing temperatures, and no heat guns nor special tools are required. HushMat is thinner, but dense to provide optimum 0.47 pounds per square foot mass.
HushMat is vibration damping (not “dampening”), thermal insulation, tape and sound absorption materials formulated to liminate noise caused by road, engine and vibrations. HushMat materials also reduce heat from engine, exhaust and sunlight. HushMat materials are the easiest aterials to apply.
dB stands for decibel. It is the physical measure for sound. The decibel scale is a logarithmic scale. This means a 5 dB SPL reduction equates to a 70% reduction in sound power in the noise. A 10dB reduction in SPL equates to a reduction in sound power by a factor of 10! The human ear recognizes a 2-3 dB change
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 the removable door trim panel 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.
HushMat Ultra License Plate Kit (Part # 10600) is designed specifically for this problem. This kit treats all USA Territory License Plates. Simply remove the license plate from your vehicle and place the HushMat Ultra sheet on the back of the plate. Trim it if necessary with a pair of scissors. Place the treated license plate and the HushMat frame (included in every License Plate Kit) back on the vehicle. Your problem is solved every time with HushMat.
Our efforts in the Automotive Industry over the past 30 years have shown dramatic reductions. Due to the number of variables outside our control – we cannot dictate exact decibel reductions in your vehicle. We do offer 30 years of experience reducing noise and heat in hundreds of thousands of vehicles worldwide. It is not uncommon for a vehicle with complete HushMat surface coverage to achieve up 10-15 dB reduction of noise.
We have spent thousands of hours measuring vehicles over the past 15 years. We have learned most vehicles have undergone significant sheet metal variation from their original stock production over their life. This means “cut to fit” is a myth. Is it cut to fit the stock vehicle or the modified one? We provide various size pieces and a template for placement for each size with every Year, Make & Model kit. We also add 5% more material as it is common for someone to damage or miss-apply a piece. This allows the customer to finish the job without having to come back and purchase more.
