Dynamat vs. Fatmat vs. Hushmat (Sound Deadener Comparison)

There are excellent reasons to soundproof your car. Mainly

  • to cut down the noise,
  • to improve the acoustics.

Soundproofing requires using sound deadening materials to cut down the noise emanating from your car engine. They also block out the wind resistance noise, vibrations, and the tire hum.

Furthermore, soundproofing can make your vehicle more acoustic. The car doors are made out of metal, which isn’t exactly the most acoustic material. Since the speakers are mounted on it, it’s necessary to add some type of sound deadening material to improve the overall sound.

Fatmat vs Dynamat vs Hushmat - Best and most popular sound deadening mats - Detailed reviews and comparison.

But, what sound deadening material to use? We already have an article on Ten best automotive sound deadening materials. However, today, we decided to give you a more in-depth review.


You’ll find ample information on all three materials, as well as an objective comparison so that you can make an educated decision. Therefore, let’s dive into the comparison of the three most popular sound deadening materials. You can see for yourself which one comes out as the winner. The factors taken into account are:

  • effectiveness
  • installation process
  • price
  • heat resistance
  • odor and the base of the material
  • usage


The three contenders have a wide range of efficiency. The absolute winner is the fan-favorite Dynamat. However, Fatmat and Hushmat have their advantages, as well.


  • thick
  • dense
  • extremely effective
  • cuts the road noise in half

Dynamat is the most effective sound deadening material on the market. In fact, it’s so efficient that even partial coverage will give dramatic effects. Dynamat has different kits for floor, hood, doors, trunk, and headliner. The fact that it’s customizable increases the sound deadening effectiveness. You can also buy it in bulk.

Dynamat is a butyl-based material. Therefore, it’s stretchy, but it will not tear easily because it’s sturdy and thick. The dense material will reduce the road noise by 9 to 18 dB. That means it can cut the noise in half! However, you will need to layer your whole cabin for this effect, which is somewhat pricey.


  • thinner
  • asphalt-based
  • adequate

Fatmat is an asphalt-based material (read Butyl vs Asphalt-Based Materials). That, unfortunately, means that it doesn’t do well in high temperatures. Furthermore, this also makes the installation more difficult. This material is not rubberized like Dynamat and Hushmat, so it doesn’t have such dramatic impacts on the road noise.

Fatmat is also thinner than Dynamat, and, therefore, less effective. However, it does make a difference. It will effectively dampen the noise and make your cabin more acoustic when applied to the doors.


  • butyl-based
  • available in different kits
  • cost-effective

In terms of bonding, thermal resistance and sound deadening, Hushmat is similar to Dynamat. You can rely on it to dampen the road noise and improve the acoustics of your car. Hushmat is butyl-based, and therefore extremely heat-resistant.

It is, however, less thick than the Dynamat, and lighter. But, it’s more effective than the Fatmat. Therefore, it will significantly reduce the road noise and the vibrations in your car. Just like the Dynamat, it comes in different kits. You can purchase the floor, door, and bulk packages.


As for installation, you can seek professional help, or you can have a go at it yourself. However, our three competitors aren’t equal contenders in this category.


  • hard to install
  • thick material
  • difficult to cut into

As you know, Dynamat is the most effective and the most popular sound deadening material. However, it comes at a steep price, but we’ll talk more about that later. The other downside of the Dynamat material is that the installation process is somewhat tricky.

Dynamat is highly effective because it’s thick and sturdy. And, that’s precisely what you want for soundproofing. However, that also means that you’ll have difficulties cutting into this material. The density of the material will definitely prolong the installation process. So, prepare more than one box cutter.


  • not that easy to install
  • asphalt-based
  • not heat-resistant

Fatmat is self-adhesive, but you’ll probably need to use additional adhesives, like a glue gun, to make it stick properly. Because this material is asphalt-based, it’s hard to install. The asphalt base does not mix well with high temperatures. Therefore, the heat you need to use during the installation to make the Fatmat stick to the surface of your car will cause the material to seep out. So, be prepared for a messy process.

Also, don’t let the material stick to itself – you’ll never be able to separate those pieces. The surface you want to apply Fatmat to must be clean, as it won’t stick to it otherwise. 


  • easy to install
  • heat-resistant
  • easy to remove

Unlike Dynamat and Fatmat, Hushmat is reasonably easy to install. Because this material is thinner than the Dynamat, it’s easier to cut into. Therefore, the installation process will be more straightforward. Unlike the Fatmat, it isn’t asphalt-based, so it’s resistant to high temperatures. That means less mess during the installation.

Hushmat is also easy to remove. That’s great if you want to replace it. But, it’s a real hassle when it falls off during rough rides.


Sound deadening materials are very versatile in use. You can use them for more than just soundproofing your car.

  • noise and vibration control in the car
  • thermal blocking
  • soundproofing of home appliances
  • sound and thermal proofing of PCs and other computer equipment
  • marine vehicles, heavy vehicles, and RVs


You can use Dynamat anywhere you need noise and vibration control. Dynamat has products available for soundproofing your cars, homes, appliances, hardware and building structures.

Aside from acting as a thermal and sound barrier in your car, you can use Dynamat to soundproof home theaters and appliances. You can also use it to improve the sound of your ceiling and wall speakers, as well as to dampen the noise between rooms or floors.

However, Dynamat has specific kits and packs for each of these uses. Those can be very pricey.


Unlike Dynamat, Fatmat has one product that fits all your needs. You can use Fatmat sound deadening material to control the noise of your home appliances, computers, and other hardware, as well as boats and engines.


The primary applications of Hushmat are automotive and audio applications. However, Hushmat also offers solutions for heavy vehicles, like fire trucks, Peterbilt and Western Star trucks. Furthermore, Hushmat has kits for marine vehicles, like boats and ships, and for RVs. Lastly, you can also get a universal kit. It’s multipurpose, and you can use it for any of the applications mentioned above.


As with any other product, the price range of sound deadening materials varies.


Among the three contenders in this review, Dynamat takes the dreaded title of the most expensive one. Therefore, if you’re looking for a more cost-effective material, keep looking. The Dynamat is the most potent material when it comes to soundproofing, but the dramatic effects come at a steep price.

The price of Dynamat is around $5 per square foot. That is very pricey, especially if you’re considering soundproofing your entire car.


Fatmat falls under the relatively cheap category when it comes to sound deadening materials. Unlike the Dynamat and Hushmat, which come in sheets, this material comes in roles of 100 square feet. The price per square foot is around $1,5. That is the most cost-effective option. However, you can get smaller rolls if you need them, but those have higher prices per square foot.


Hushmat has higher prices than the Fatmat. If you choose their bulk kit, the price per square foot is around $1,8. The bulk kit has 30 4-square feet sheets. However, their specialized floor and door kits are more expensive. Those will cost approximately $4 per square foot.

Dynamat vs. Hushmat vs. Fatmat - How do these sound deadeners compare in term of price.


Because the Dynamat and the Hushmat are butyl-based, they are incredibly heat-resistant. Unlike them, the Fatmat is asphalt-based, which means it doesn’t bode well at high temperatures. Therefore, if you’re from an area known for hot summers, you might be more inclined to choose one of the butyl-based materials.

Dynamat and Hushmat can withstand the heat of more than 240 ℉, while the same cannot be said for the Fatmat.

Furthermore, due to the fact that it’s asphalt-based, Fatmat emits a distinct odor when exposed to high temperatures. It cannot withstand high heat conditions. You can experience some leaking because, when exposed to high heat, the material can seep out. Users also report that there is a rubbery smell present for long periods after the installation of Fatmat.
