There are so many materials that you could use to deaden the noise in your car.
Unknown to most car owners, sound deadening materials come with a lot of other benefits as well. They also help keep the weather in the car pleasant.
Temperatures can go very high or low in the car depending on the season.
Most sound deadening materials will help you solve this problem. They keep the weather cool in the car during summer and warm during winter.
What’s more, these materials are quite affordable and are lightweight with very easy installation procedures.
I love my car being quiet and over the years, I have used quite a number of automotive sound deadening materials. Another great thing about these solutions is that they might even increase the price of the car, if you ever decide to resell it.
In this article, I will highlight some of the best materials out there. So, take a look.
Best Automotive Sound Deadening Materials
These are sound deadening mats that can be used to block out noise pretty much anywhere.
However, they are best suited for use in automobiles.
When it comes to sound deadening, thicker is always better.
I especially love these mats because they are quite thick. This is made possible by the fact that they contain butyl.
This makes them so much more efficient in insulation as compared to other automotive sound deadening mats.
You’d think that with all the thickness, these mats would be bulky. On the contrary, they are quite lightweight. This means that carrying them and installing them will not be cumbersome.
That’s one of the reasons these are the number one pick on our list and that they’ve been used world-wide, making them to be one of the best auto sound deadener insulations out there.
They weigh around 0.7 lbs/sqft. Their lightweight nature also plays a big role when it comes to efficiency and sound insulation.
For most people, installing is the scariest part.
With these mats, it doesn't have to be. Besides being easy to install, they also come with an indicator to show whether or not you have installed the mats correctly.
All you have to do is roll the embossing on the foil until it becomes plain and smooth.
The mats come in different sized sheets. You can use this to soundproof just about any part of your car. You could use them on the engine hood, the trunk and even under the seats.
As compared to other mats, the Noico 80 mil sound deadening mats are quite affordable.
However, the amount of money you spend on these mats will ultimately depend on how many of them you need.
Second Skin’s Damplifier Pro is the highest quality sound deadening mat that we’ve been able to find.
If best-in-class damping performance and excellent customer service are your top priorities, Second Skin is the place to go.
Second Skin Audio has been around since 2000, and is consistently reviewed as one of the best companies out there. They don’t run out of stock, and they actually answer if you need help and call or email them!
As for the Damplifier Pro deadening mat, it’s 80mils of 100% butyl rubber with a thick annealed foil constraint layer and an extremely strong adhesive.
They do not add asphalt or other cheap fillers and the specs show it. At a 450 F heat rating, it’s the highest we could find anywhere.
We like the mat’s design: black with a ghosted logo. You can put it on any metal panels in your car (doors, floor, trunk, firewall, roof, hood) to damp vibrations and add thermal insulation.
Second Skin even publishes Damplifier Pro’s technical data from a real vibration damping test lab.
Call it a breath of fresh air in an industry where it’s sometimes hard to tell the difference between products before you hold them. Second Skin lays it all out there for you.
Besides the noise, the heat in a car is another major concern for most car owners.
How good would it be to get a two in one solution then?
These mats from are just the answer you are looking for.
Besides being very efficient, and that they’re one of the easiest sound dampening materials you can use when it comes to sound deadening, they also act as a heat barrier. They have a thermal and vapor barrier allowing them to block up to 97% of radiant heat.
Although the mats do not come with adhesive, they have so many options available when it comes to installing making the process quite easy.
Just like the Noico 80 mil, they are quite lightweight.
The mats are also very flexible. Flexibility is key when it comes to automotive sound deadening materials.
You certainly want to be able to twist and turn the material depending on what are you are insulating.
It really doesn’t matter what car you drive. These mats are designed to be used on the interior of just about any car so as to provide insulation against both noise and sound.
Often, whenever we think of soundproofing our cars, mats are what come to mind.
There are, however, very many other options and these include using foam.
Foam is not a strange term to anyone who knows a thing or two about soundproofing.
The foams that are used on walls and ceilings are usually quite thick making them efficient when it comes to soundproofing rooms.
However, these foam panels are usually bulky and thus not suitable for use in a car.
The uxcell car cell foam has managed to break this barrier. It is made of the same sound absorbing materials as wall foams, only that it is designed to block out the automotive noise.
Most people disregard foam panels for use in their cars because most are not able to handle the huge amounts of heat produced.
The uxcell car cell foam, on the other hand, is a good heat insulator. Besides being able to take in all the heat, it insulates the inside of your car making it a comfortable ride.
Because it is lightweight, installing the foam in your car should be a breeze. Further, the foam comes with a super adhesive that ensures it remains in place once you are done installing it.
The foam is also quite versatile and can be used in classrooms, studios, apartments and just about any area you would want to block out the sound.
If the installation is really your biggest problem, then you might want to take a look at the FatMat self-adhesive rattle trap sound deadener.
This comes with an install kit that makes the work much easier for you. You should have it installed with the roller and the knife in a matter of minutes.
It also contains a super stick adhesive that only makes things easier.
The FatMat sound deadener is designed to specifically block out the automotive noise.
With a thickness of around 80 mils, the FatMat is quite efficient in what it does. It is also a heat insulator, absorbing all the unwanted extra heat in your car.
The mats come in eight sizes and measurements so you can only get what will suit you best. It is also a great vibration dampener and works really well in reducing distortion.
If you are a huge fan of making videos in the car, then you are really going to enjoy using the FatMat.
Rubber foam has good sound absorbing qualities and that is exactly what the Noico Liner car heat insulation pad is made of.
It is important to bear in mind the oil absorbing properties of any material used in the car. In case of a leak, a material that absorbs oil and petrol will only make the situation worse.
With this heat insulation pad, you will not have to worry about that. This is because the pad is resistant to both oil and petrol. It is also waterproof.
This sound deadening material also does a great job when it comes to heat insulation – making them to be one of the best automotive heat insulation you can get at the same time. So you can really think of this as a 2-in-1 product.
If you have a car with a very powerful engine then it is no doubt that excessive heating is a problem you are constantly dealing with. The heat insulation pad will help you out when it comes to that.
Its lightweight nature coupled with the fact that it comes with a super adhesive makes it quite easy for you to install the heat pad. The pad is also very easy to cut.
Second Skin’s Spectrum is a water based viscoelastic polymer.
It’s an excellent sound deadener and a good thermal insulator as well. Because of its high heat rating (400 F), you can even use it on the engine firewall.
Spectrum’s proprietary formula was developed by Second Skin to be non-toxic, high-end sound deadener.
Spectrum will stick to just about anything without a primer besides plastic or high gloss surfaces. It’s also easy to clean up with water if you don’t let it dry (about 30 minutes).
Once Spectrum cures, it’s seamless, odorless, waterproof, rustproof, and flame resistant.
A sound deadening spray is a solid alternative to the mats, especially if you prefer to spray or brush on your sound deadener instead of cutting, peeling, & sticking.
You can make really quick work of the job with a compressor and a spray gun, and even reach some of the parts of the car that mats from trouble with like the underbody or inside the wheel wells.
You also have complete control over the thickness of your install, so you can decide how much weight and deadening to add.
Second Skin recommends 2 layers of 1mm each for a total of 2mm, but you can go up to 5mm total.
If you’re on a tight budget and you’re trying to save up soundproof your car efficiently – KILMAT makes a decent 80 mil deadening mat.
Even though it’s pretty lightweight and is 80 mil thick – it’s effective at soundproofing that it can be compared to brands such as Gtmat, Boom Mat, or even Extreme.
One of the advantages is the self-adhesive feature which consists of butyl and it’s fairly simple to install it since it comes with a special indicator that helps you install the mat correctly.
Not only you won’t need professional help – but you will feel like a professional at installing the sound deadening mat.
What we really liked about KILMAT mats is that they come in decently-sized sheets that will fit easily in most parts of your car. However, they’re also easy to cut so you can make smaller sheets for corners or tricky places.
If you’re looking to soundproof your car interior from road-noise, squeaks, rattles or vibrations – placing KILMAT mats anywhere from the hood to the trunk or even front & rear wheels will help eliminate the annoying sound.
One of the most useful things is that these mats can hold up well in both low and high temperatures – so you can literally place them anywhere on your car.
Siless is one of the most underrated sound deadeners on the market – and they reason for this is that Siless Liner doesn’t only deaden the noise, but also deadens the vibration and heat as well.
It’s a bit thicker than the average sound deadener material, being 157 mil thick, but it’s still pretty versatile & flexible which makes installation simple.
One side features an adhesive glue that requires no professional help to install and yet it won’t take up a lot of your free time. One thing we’ve noticed is that the glue is waterproof so if you live in a rainy location, you won’t need to wait for your car to dry out 100%.
Another side features insulation material where the thermal barrier is placed between these two sides.
Not only you will eliminate the noise within the interior of your car – but during hot sunny days, your car might even feel a bit chillier than ever before because this material blocks heat from sun, exhaust, or engine.
This also applies vice-versa, making your car stay warmer for longer in winter. However, no matter how long you drive your car – this deadener can stand up to 215 degrees Fahrenheit, so once you install it in your car, there’s nothing to worry about afterward.
We’ve noticed that depending on the surface you’re applying this deadener to, you might not need to use a roller for every single piece of deadener you install.
This speeds up the process and helps in case you don’t have a roller that is often required by other sound deadeners.
When the price isn’t the problem but you’re doing your best to avoid hiring professionals – FatMat doesn’t only provide simple & easy to use sound deadener mat, yet they also provide everything you need to get the job done yourself.
This is a second FatMat sound deadener and one of the main differences is the thickness. Black Butyl MegaMat is also softer which makes it easier to install in corners or extra small spaces.
We believe combining both FatMat RattleTrap and Black Butyl is a great way to make your job easier and yet achieve a very high level of noise reduction.
However, along with the FatMat self-adhesive Black Butyl sound deadener mat, you will also get an install kit that includes everything from the knife, roller, and control decal – along with the step-by-step instructions.
FatMat Black Butyl sound deadener is 70 mil thick and the downside is patented with a super-stick self-adhesive glue that makes installation a breeze. Yet the top features one of our favorite finishes since it’s matt black finish that goes well with most car interior & exterior colors.
Therefore, if you’re having a hard time hearing your favorite tunes inside your car – maybe it’s not the right time to upgrade your speakers yet it’s the right time to take action on the noise you hear most of the time.
FatMat Black Butyl offers 5 different lengths and you can always cut the deadener to fit it into the smallest parts of your car.
The most important factor is that this sound deadener is made of heat-resistant aluminum which makes it a good choice for blocking the noise engine by placing the deadener under the hood.
