Automotive sound deadening is a dime a dozen, so what makes the Heatshield Products acoustical insulation materials so special? While other companies have focused on their marketing, we have focused on getting you the right product for the right problem. Noise inside a vehicle is caused by multiple sources, so a one-product-fits-all approach with car sound insulation won’t work.

We offer lightweight, high-tech automotive sound insulation materials to solve your acoustical problems. You don’t have to add 500 pounds of dead weight to your ride to reduce noise: by using the Heatshield Products’ line of sound deadening materials for cars, you can make your ride quiet without turning it into a whale. Stick-on foil automotive sound insulation works well with low- to moderate-frequency sound waves generated by vibrations that originate within the vehicle, but are ineffective asadampers of road noise. Road noise is a higher frequency than what most acoustical dampers are designed to suppress, and is best stopped by closed-cell foam products with a hard vinyl barrier that functions as a sound barrier, not a sound damper!



db Armor – The most effective stick on sound insulation on the market. 20 percent lighter than extreme sheets with 1.5 times the auto sound insulation capacity.

Stealth Shield – The only proven insulator to reduce heat from the inside of the vehicle.

db Skin – Light weight, liquid sound coating. Goes on purple, dries black. It may be sprayed, rolled, or brushed onto clean primed surface.

db Sniper – Used for road noise frequencies, exhaust drone. Used with a stick on damping sheet can achieve a luxury vehicle level of sound insulation.

db Defender – Heat moldable lightweight sound insulation for inner door panels.

db Gasket – Used to mount speakers. Also may be used outside of vehicles for license plate brackets or any metal to metal vibration noises.

Heat Reduction Myth - Stick on sound dampers are not designed to stop heat. Sticking a butyl sheet on the ceiling of your car not only adds unnecessary weight ruining your center of gravity, it does nothing for automotive insulation and sound deadening. You see it on almost every big build in a magazine, you see it on the TV shows and yes, they are all doing it wrong. That may have worked in the 1990’s, there is a newer better way. For roof panel insulation we would suggest our db Skin with our Stealth Shield to stop heat from radiating into the roof panel of your car.

Proposition 65 requires businesses to provide warnings to Californians about significant exposures to chemicals that cause cancer, birth defects or other reproductive harm. These chemicals can be in the products that Californians purchase, in their homes or workplaces, or that are released into the environment.
