As the name implies, sound deadening mats are used to reduce the amount of outside noise that is able to enter the inside of a car. Common vehicular noises include wind and vehicle vibrations. These noises can range from a faint hum to a noisy rattling. For drivers who spend a considerable amount of time in their vehicles, background noise can be a major distraction.
Sound deadening mats are also known to improve the quality of a vehicle sound system. By isolating outside sound and creating a sound-canceling barrier, these mats can also improve the quality and range of sound produced inside of a vehicle. On top of that, sound deadening mats insulate against intensive cold and hot temperatures.

At a mere $1.65 per square foot, the Kilmat 80 mil nutyl sheets are some of the best-selling sound deadening mats on the market. Of course, the thick butyl and aluminum sheets perform just as well, if not better, than the competitors.

As such, they are incredibly easy to work with. You’ll need to purchase a rubber roller to smooth out any bubble in the foil before setting it in the vehicle of your choice. Once you do this, you can cut and fit the sheets with ease.
If you need a bit of guidance on what quantity to purchase, Kilmat provides precise coverage calculations.
Wrapping things up, the Kilmat logo adds a nice touch to these silvery sound-canceling panels. The Kilmat 80 mil even has built-in indicators that let you know if the mats are installed correctly. They consist of raised dimples that need to be pressed down.
Kilmat’s claim to fame is that they provide “an extra 50 percent of the quality for just 30 percent of the price.” We took a look at other top-selling brands, like Dynamat Xtreme and Stinger, and found this claim to be pretty accurate. The Dynamat 80 mil stays in place for extended periods of time.
On top of that, it dramatically decreases the amount of roadway sounds that seep into a vehicle. It also improves the internal acoustics of a vehicle, transforming standard speakers and stock radios into appetizing audio production systems.
2. Noico 80 Mil Car Sound Deadening Mat – Editor’s Choice
Yet another solid sound deadeners, the Noico 80 mil deadening mats offer superior automotive sound and heat dampening.

We found the Noico mats to be rather pliable and easy-to-cut. Keep in mind that you will need a small precision cutter, a few replacement blades, and a rubber roller to complete the installation process. Once you’re ready to install the sheets, remove the protective film and press the mats down. Use the roller to remove the dimples, or crimps in the foil. Once the product is completely smooth, you will know that you’ve installed it correctly.
Some customers have reported that the Noico mats have a subtle asphalt-like smell. However, we did not notice any scent. On the other hand, the material is razor-sharp and super sticky. As such, we recommend wearing durable work gloves when prepping and installing the mats.

5. Thermo-Tec 14620 – Easiest Sound Deadening Mat To Trim and Fit
We’re big fans of the ultra-affordable Thermo-Tec sound deadening mats. They have a 70-mil nominal thickness and measure 36-by-60 inches. They also have a temperature-reducing liner that makes them great for firewalls, car floors, and other temperature-sensitive locations. The sheets come equipped with a preset adhesive liner that’s extremely strong and easy to set.
With tricky installations being the number one customer complaint concerning sound deadening mats, we were pleasantly surprised with how easy it was to cut and trim the Thermo-Tec sheets. We had no problem adhering them to tight areas, including our engine covers and wheel wells.
The material dramatically decreased the amount of sounds from our engine and trunk.
Not to mention, it helped intensify the output of our stock sound system. While we were rather skeptical of this material because of its low price, it proved to be superior to far pricier alternatives.
After testing out several smelly sound deadening mats, we were happy to discover that the Thermo-Tec mats were virtually scentless. On top of that, the adhesive was extremely strong. With that said, we found that the adhesive was not able to handle high heat. As such, it melted in the hot areas of our vehicle. While this was somewhat troublesome, the Thermo-Tec pads themselves did not show any signs of wear or tear when exposed to heat. Given the extreme affordability of these mats, we’d consider using them with an aftermarket adhesive.
Best Car Sound Deadening Mat – Buyer’s Guide
Wondering what makes one sound deadening mat better than another? Manufacturers utilize a wide variety of materials and designs to great sheets of material with sound- and heat-reducing capabilities. Read along to explore different options and narrow down the best choices for your vehicle.
Types of Sound Deadeners
- Materials. Most sound deadening mats are made from butyl. Butyl, also known as butyl rubber, is a synthetic polymer that was produced by two American chemists in 1937. (put names) Many sound deadening mats also feature a thin layer of aluminum. The butyl side of the mat is installed directly against the metal frame of the vehicle.
- Sound Deadening Car Mats. Sound deadening car mats are used to cover key elements of vehicles in order to block out common roadway sounds. They tend to come in rolls or sheets that can be cut and shaped to fit.
- Sound Dampening Sprays. Many car owners use dampening sprays to fill tight spaces where sound deadening mats won’t fit.
- Foam Insulation. Foam insulation is one of the preferred sound deadening materials for doors. That is because it’s super lightweight and easy-to-install.
- Thickness. Thicker is always better when it comes to sound deadening materials. Most sound deadening mats have a nominal thickness of around 80 mils. However, some mats have a nominal thickness greater than 200 mils. With that said, it’s important that a mat is still lightweight and pliable. Otherwise, the installation process can be extremely difficult.
- Weight. Material and thickness have a big impact on a mat’s weight. A square foot of sound deadening material should weight less than a pound.
- Adhesive. For ease of installation, consider purchasing self-adhesive mats. Many manufacturers use super strong adhesives that ensure that the mats stay put for an extended period of time. The self-adhesive mats make the installation process easier too.
- Coatings. Many sound deadening mats have an aluminum coating. Aluminum is resistant to heat and, therefore, helps insulate your car in addition to reducing sound. Heat-resistant sound deadening mats are commonly used to line vehicle hoods, as it keeps them cool.
- Pliability. It’s important that a sound deadening mat is pliable and easy to work with. Many people consider installation a D.I.Y. job.
- Aesthetics. Mats vary in aesthetics. Most are black or silver in color. Some have gridded logos stamped across them, while others have a solid design. Keep in mind that you will be placing them underneath your car door, roof, and panels. As such, the aesthetics of your sound deadening mats is not very important.
If you’re planning on soundproofing your entire vehicle, it’s important to target specific areas based on their individual sound production potential. While most of the key elements of a car can be covered with sound deadening mats, sprays and insulation patches may be needed to fill in small gaps and difficult to reach areas.
You’ll want to start by covering your doors, floors, trunk, and roof. These areas are subject to wind noise, mechanical interruptions, and car audio distortion. On top of that, you’ll want to cover the firewall and hood. It’s important to note that these areas conjure up a good amount of heat. As such, you must use heat-resistant materials to avoid damage.
While many sound deadening mats come in pre-cut sections, you’ll still need a small utility knife to trim pieces to create a precise fit. Depending on the type of mat you are using, you may also need some sort of mat adhesive for sticking, a rubber rolling tool for smoothing, and/or a small heat gun for shaping.
Sometimes, sound deadening mat kits come equipped with all the necessary installation gear. However, in most cases, you will need to purchase these items separately. On top of that, many manufacturers provide coverage estimates for customers to reference. You will probably need two or more full rolls of sound deadening material if you intend to soundproof you are aiming for a full-coverage installation.
Boosting Sound Quality
While it may seem ironic, many vehicle owners utilize sound deadening materials to boot the quality of their car audio system.
High-quality mats eliminate unwanted vibrations and reduce the amount of roadway sound that enters your vehicle.
As such, they can increase the sound pressure (SPL) inside a vehicle. With more pressure, sounds are perceived as being louder at lower volumes. For example, most high-quality professional speakers have high sound pressure at low volumes.
Remember, sound pressures higher than 85 decibels can damage human ears. As such, it’s important to reduce the volume inside your car to a volume lower than 80 decibels. You wouldn’t go out of your way to punch holes in your speakers, so why damage the one sound system element you can never replace?
Tips and Trick
Pro Tip: If you purchase a solid sound deadening mat, installation shouldn’t be too difficult. However, the following tips and tricks will help you avoid common blunders.
- Wear Gloves. If you don’t want it to look like you’ve been holding hands with Edward Scissorhands, invest in a high-quality pair of work gloves. Sound deadening mats can be razor-sharp when cut.
- Use Degreaser. Car frames are often grimy or greasy. Purchase an inexpensive degreaser and prep the surface of the frame before adhering a sound deadening mat. Otherwise, you run the risk of wasting material.
- Read the Instruction Manual. Some sound deadening mats boast specific instructions. Read the instruction manual before removing the adhesive backing. You’ll want to avoid any unnecessary interruptions.
- Apply Pressure. While not all sound deadening mats require rolling, it is important to apply firm and constant pressure when completing the installation process. You want to hold the mats in place to ensure that the adhesive has had time to bond to car surface.
- Take Additional Steps. If you’re installing sound deadening mats to improve the quality of your car audio, consider making a few additional improvements. Replace your stock speakers with superior six-by-nine speakers or opt for more superior audio files. There are a lot of factors that go into the enjoyability of car audio, and sound deadening mats are an excellent place to start.
