Reviews of 10 Best Automotive Sound Deadening Materials

Installing sound deadening materials in your vehicle will completely change your life. However, if you’ve never considered doing that, getting into it can be a bit overwhelming. What are some of the best automotive sound deadening materials on the market? Which brands should you use or avoid?

I’ll admit it, when I started looking for ways to make my life quieter, I initially neglected to think about my car. But can you blame me? Like many other people, I didn’t really know why someone would need to soundproof their vehicle or even what that would look like.

Well, if you’re like I was all that time ago, you’re in luck. Today, I’m going to answer some of the most common questions people have about sound deadening products for cars:

  • Which types of products are out there and what are their uses?
  • What are some of the features you should be looking for when you shop?
  • Which tools do you need to apply them?

And, of course, I’m going to review 10 of the best automotive sound deadening materials as well. But first, let’s start at the very beginning.

Best automotive sound deadening materials reviewed.

a) Sound Isolation Types

As you may be aware, soundproofing materials on the whole serve one of two purposes. They’re either sound blockers — so they prevent noise from going in and coming out of a space — or they’re sound absorbers. The latter type of products actually softens the sound within a space. If you have acoustic foam in your home, you know exactly what types of effects you can expect from these products.

Well, automotive sound deadening materials serve slightly different purposes. Actually, many of them act as both blockers and absorbers. But they also need to be able to prevent the rattling of metal parts within the vehicle. So let’s discuss what types of products we can use to improve the sound quality inside a car.

b) Material Type

There are four available materials when automotive sound deadening is concerned that come to mind. Each of these materials absorbs various vibrations, sound waves, and resonance in their own ways. Just as equally, each of these materials has its own intended use, meaning that some of them can’t be used in all areas. They are as follows:

  • Sound deadening car mats: They are usually the first thing that comes to mind, and people often use them to cover panels.
  • Woven fiber and foam insulation products: These two types of insulation products are other options you might use underneath the carpet and the floor mats of your vehicle.
  • Sound dampening sprays: They are used in situations when regular matting is impossible. It is the least used method because they are dependent on using a compressor in order to be applied.

Sound deadening mats for cars can have multiple uses. Not only are they good for sound isolation but they also keep the temperature cool/warm in the car. They are quite affordable, lightweight, and easy to install as well, which are additional benefits.

c) Thickness

This factor is almost self-explanatory. You can either opt for a thicker material or a multilayered use of the regular ones. Either way, the same rule applies; the thicker your sound insulation, the better.

d) Size

The size of the material that you get solely depends on the surface area that you intend to cover. Sound deadening materials for cars often come rolled up. That means that you can cut them however you want in order for them to fit a particular shape. On the other hand, some manufacturers sell them in sheets/patches, which are more suitable for smaller area coverage. There are several other options, which are mentioned above (sprays and insulation) but their use is limited to certain areas.

10 BEST SOUND DEADENING (INSULATING) MATERIALS CURRENTLY ON THE MARKET

If these products are listed according to any particular order, it’s going to be according to their popularity. Or, at least according to their reputation. So I will start with the one people have the most good things to say about. But we’ll see if it can be beaten by one of the other products on my list.

Still, you should keep in mind that all of these sound deadening materials are on this list for a good reason. With that being said, let’s just dive into these reviews.

Dynamat is definitely the most famous sound deadening mat brand on the market. But, before you start thinking that they don’t deserve that reputation, allow me to explain why this company’s products have long been considered the most effective automotive soundproofing materials around.

In fact, Dynamat might be the original aluminum-front, butyl-back product. It offers a great reduction in sound and vibrations. And since it’s a butyl material, it’s also particularly heat-resistant and odorless. Not to mention that it’s pretty easy to apply, at least when you know what you’re doing.

The one criticism Dynamat customers have for the company seems to be its pricing. I’ll admit it, I’ve harped on this point in the past. However, I’ve also admitted to the fact that the price may be justified, when you think about the advantages of using Dynamat. Still, I can’t say that I’m not pleased with the fact that it’s no longer the only automotive sound deadening product on the market.

The 67 mil Dynamat Xtreme is probably one of the most effective products in the company’s lineup. According to the company, this product is actually lighter than the original version of Dynamat and 4 times as effective. Apparently, you’d need heat to apply the original Dynamat. Thankfully, that’s not the case anymore.

Nowadays, the brand has several versions of the product available, including some that are specifically made for rear decks, cabin or trunk floors, or doors. There are even different weights of the product, as you can see from the Dynamat SuperLite bulk pack. Although this thinner version of the product may sacrifice a bit on efficiency, it’s much easier to install than regular Dynamat.

Features:

  • The most famous brand on the market
  • A lot of happy customers
  • Excellent sound, vibration, and heat deadening material
  • Quite easy to install
  • High Price

In addition to the Dynamat sound deadening mats, there are also several other products you might use in your car.

The company released separate products for each part of your car in order to increase the overall success of their products’ performance. Each of these products can be used together in order to achieve maximum efficiency. There are Dynapads (for floors and trunks), Dynaliners (for headliners), and Dynamat Hood liners (for the hood). As far as vibration, sound, and heat reduction is concerned, they are second to none.

1.1. Dynaliner and Dynapad

Dynaliner and Dynapad are both Dynamat products that have their own purposes. For example, the primary purpose of Dynaliner is to improve your car’s heat-resistance and deaden the sound.

While Dynamat can be used anywhere around the car, this synthetic rubber foam material is usually confined to the doors or under the hood. After all, these are the usual areas we usually worry about letting heat in. So if you’ve had issues with that before — or you frequently find yourself leaving your car out in the sun — something like this might come in handy.

The material comes in several thicknesses, with the thinnest 0.12-inch one being the only one to be able to fit inside a door. On the other hand, Dynapad is about as thick as the thickest version of Dynaliner, at about 0.45 inches.

Unlike Dynaliner, this product is waterproof — as it should be, if it’s going to go on the floor of the car. Also, unlike Dynaliner and Dynamat, Dynapad isn’t self-adhesive. Since it’s going to go under the carpet, you can just put it on the floor, cover it with the carpet, and forget about it.

I’ve already written about the differences between these products before, so you can check that out if you’re curious to know more.

There is really nothing bad to say about Dynamat, except for the price, which is pretty steep. However, it’s a known fact that this is a popular brand name and so it might be a bit more expensive, but it definitely delivers.

But now, let’s talk about a brand that’s built their reputation as the more budget-friendly version of Dynamat.

Ever since people started figuring out that Noico products can get them results that are similar to the ones Dynamat gives them but at a lower price, this brand has been gaining in popularity. In fact, I’ve even written a more in-depth comparison of the two before.

Long story short, while Dynamat is technically the purer butyl product, Noico gives you nearly the same quality at a lower price. Besides, if the brand that comes out with the thickest deadening mat wins the match, then Noico’s 80 mil mat is the clear victor here.

Features:

  • Butyl-based material with asphalt undercoating
  • It works great with any car surface
  • Thicker than Dynamat
  • The overall installation is user-friendly
  • Rubbery scent

That version of the product comes in a pack that can cover a surface of 36 square feet. However, there are also smaller coverage packs, of about 10 or 18 square feet. Additionally, if you’re concerned with the appearance of your vehicle in the places where the foil top layer of the mat will be visible, you can rest easy. Noico also makes a black version of this product.

There are also various other thicknesses available for those who don’t need that much coverage, such as the 50 mil Noico mat. And, their other products can be even thicker than 80 mils.

2.1. Noico Green Liner

The Noico Green liner is Noico’s answer to Dynamat’s Dynaliner. The 170 mil sheets come in 18 square foot packs. This product is actually closed-cell polyethylene foam that serves as both heat and sound insulation. It will easily withstand temperatures up to 212 degrees Fahrenheit.

These liners are both meant to block the noise coming out of your engine. They’re also supposed to prevent the heat from the engine from damaging the paint on top of the hood. Additionally, the fact that this material is water, oil, and petrol-resistant is also pretty great.

Although Kilmat isn’t the most talked-about name on this list, it’s definitely one of the best sound deadening materials on the market. It manages to stay within the same price range as some of the budget-oriented alternatives out there while still performing good.

The 80 mil foil and butyl mat absolutely deserves a mention because of its excellent handling of engine noise, loose metal rattling, vibrations, and outside noise. So, you could say that it’s a bit universal in that regard.

Features:

  • A universal sound dampening material that equally eliminates indoor and outdoor noises
  • 80 mil thick, weights 0.5 lbs/1sqft
  • Butyl and foil sound deadener
  • It requires a steady hand and a lot of patience when installing

However, even though this material will be able to handle any noise that comes its way — you may not want to handle it. According to some users, the material has had a tendency to be a bit unwieldy. But since that’s also been said about Dynamat, I’m not too worried.

Besides, this product comes in precut 9.8 by 15.7-inch sheets, with a single pack covering 36 square feet. If anything, that leaves you less work than you’d have if you were working with a roll of butyl deadener.

Hushmat is another automotive sound deadener that might be a great alternative to Dynamat. In fact, it definitely came out on top when I compared the two in a previous article. This sound deadening mat is definitely less expensive than Dynamat, and perhaps even easier to install.

Furthermore, due to Hushmat being another butyl material, you can expect the same kind of performance out of it. So it’ll significantly reduce road noise, improve the interior sound quality, as well as provide padding for loose metal parts to hit.

Additionally, since this mat is a butyl-based product, you needn’t worry about the heat damaging it or stinking up your car. In fact, Hushmat will reduce the heat for up to 40 percent. And it’s able to withstand temperatures from minus 30 degrees Fahrenheit to 400 degrees Fahrenheit.

Features:

  • Greatly reduces road noise in the car interior
  • It can withstand high temperatures
  • There aren’t enough sheets in one package to cover the entire car, but there are also larger coverages available

Hushmat is also one of the more unique-looking products on this list. Unlike most of the silver foil topped sound deadeners I’ve mentioned, this one comes in a black foil finish. So if you like your car to look a certain way, that’s an option you might use.

In the article I’ve linked to in the previous section, you’ll have seen that I had Fatmat facing off against Dynamat and Hushmat. In retrospect, it might have been slightly unfair to add this asphalt-based material into that competition.

Still, this material is such a crowd-favorite that I felt like I had to include it today. Besides, Fatmat has really improved since I’ve written that comparison article. For one, the 50 mil version is no longer the thickest one.

Now, there’s an 80 mil roll that seems to be performing pretty well according to users. The 80 mil deadener is available in various surface coverages, including 25, 50, 75, and up to 200 square feet.

Features:

  • Asphalt-based material
  • It does not require additional adhesives (the rolls are self-adhesive)
  • There is enough material to cover the entire surface of your vehicle
  • The material is difficult to cut and can gum up your utensil

However, I’d assume that this material still has some of the drawbacks I’ve told you asphalt is prone to. Namely, that it’s not as game-changing in the noise reduction department as some of the butyl products I’ve listed. And then, there’s the peculiar smell — though I’m told that it goes away after a while.

5.1. Fatmat Sound Deadening Hood and Floor Liner

In addition to the run-of-the-mill deadening mat we just talked about, there are also many other products in Fatmat’s lineup. For example, their self-adhesive hood liner seems to be a great way to quiet the sound of your engine. It’s essentially a 0.75-inch thick foam product with adhesive on one side and foil on the other. The aluminum foil front faces the engine, which protects the paint on top from peeling from the heat.

Additionally, Fatmat also makes a 0.25-inch vinyl and foam floor liner as well. This product is supposed to block road noise from getting inside the cabin. Unlike some of the other floor liners we’ve seen on this list, this one is self-adhesive. So it won’t budge once you set it up.

The SoundQubed Q-Mat is an 86.6 mils butyl deadener looks pretty unique in comparison to some of the other products I’ve reviewed. Rather than have a silver foil front, this product has a black foil with its green logo plastered all over it.

The way this product works is pretty standard, though. The adhesive butyl at the back reduces the vibrations of the vehicle as well as the rattling of loose metal parts. Additionally, it also decreases road noise and improves the internal audio quality inside the cabin.

This is all to be expected of the materials on this list. However, the one thing this deadening mat has over the more famous ones on this list is the price. But if you’re really concerned with the price, I’ll point you to the article I linked to in one of previous reviews.

Features:

  • The material is quite sticky due to its butyl component
  • It is a pretty good soundproofing material (reduces the noise from the outside)
  • You might need to apply more layers to achieve the aforementioned effects

As of right now, the material comes in 16 square foot rolls, though 40 square foot ones also come into stock from time to time. Those just tend to sell out more quickly, so you should keep an eye out if you’re trying to snag one. Or you can just get several smaller rolls.

As its name suggests, this material aims to work as both sound and heat insulator. Unfortunately, it partially succeeds in that regard. Even though it reduces the sound that comes from the outside as well as the inside of the vehicle, it does not fare well against high temperatures.

Features:

  • It’s good for areas such as doors, firewalls, and floorboards
  • The material itself reduces radiant heat effectively
  • The glue can’t handle the heat, and it starts to melt

Its polyethylene surface offers protection from the outside radiant heat sources, but there is a possibility of it ungluing during such conditions. The reason for this is that the bond between the material and the adhesive is not resistant enough. If we put this aside, it is a generally good sound absorber, especially when installing in areas such as firewalls, floorboards, and doors.

The B-Quiet Viscoelastic Sound Deadener is just what it says it is. Not only is this product incredibly flexible but it also has all of the great properties of butyl deadeners. So it’s heat-resistant and odorless as well.

The 60 mil material comes in foot-wide 12 or 50 square foot rolls. The material’s flexibility will certainly make it very easy to install. However, it doesn’t come with any additional products to help with the installation process.

This material actually works by converting the vibrations of the car as well as the vibrations the other impact noise we’re surrounded with when we’re driving into thermal energy. As such, this material is the perfect protection against most types of noise.

Features:

  • It’s extremely flexible and can be installed anywhere
  • The material effectively converts vibrations into thermal energy
  • It does not come with additional equipment
  • Sound deadening is partial in some cases

Still, the manufacturer also recommends combining some of their products by topping the B-Quiet Extreme or Ultimate mats with their Vcomp composite noise barriers. That’s pretty much unnecessary in my opinion, so you can simply use the Ultimate deadening mats without any additional products. A single deadener would surely be easier to install than layering several products would be.

I wanted to mention the Uxcell Car Noise Deadener because it’s pretty different from a lot of the other products I’ve shown you. However, it’s also very effective. Why is that?

Well, it could have something to do with the fact that this mat is 394 mils thick. At this point, we shouldn’t even be talking about mils, but inches. The 0.39-inch, 10mm, liner is obviously very thick. Apparently, the mat could actually fit wherever you need it to be, though I suspect that getting it inside of doors might prove to be a challenge.

Features:

  • It’s scratch resistant
  • This material is a good heat insulator
  • Not suitable for larger surfaces
  • The thickness makes the application more difficult

Once in place, the mat might even block heat from coming into the vehicle, as well as sound. What’s more, the thick material is even waterproof. It applies in the same way you’d apply other mats, and it even has a self-adhesive back. However, because of its thickness, it may add to the overall rigidity of the car.

The thickness of the material may be its downfall as well. Although it can only mean good things when it comes to soundproofing, it will certainly make the application more difficult. Many people have a bit of trouble cutting thicker mats. Still, going on a distraction-free, silent drive may be worth the longer application process.

GTMAT sound insulator comes in two rolls which are 25 square feet in length and 16 inches in width. There is also a biodegradable degreaser, 2 GTMAT decals, and an application roller. When it comes to the material itself, it is a decent sound absorber since it has a rubberized compound which adds mass to rattling parts within the car.

Features:

  • Easy user-friendly application
  • Good sound insulator
  • It is a bit expensive
  • It comes with the application roller, although it is of a lower quality

The application is pretty straightforward. The only thing that you need to pay attention to is to apply constant pressure when using the application roller. Applying pressure is important because that way you ensure that the bond between the adhesive and the panel is strong.

The downside of this product is its price. It is a bit pricey for what it offers, and there are certainly better alternatives out there. But that’s why it is listed here and not as the best material.

FINAL THOUGHTS ON SOUND DEADENING MATERIALS FOR CARS

Ultimately, if you’re looking for good and reliable sound deadening mats for your car, I’d stick to Dynamat or Noico. Those two are the most popular products on the market by far. However, Noico is definitely the more affordable and even the thicker option — it’s definitely the fan favorite. And if you’re looking for a more in-depth comparison of the two products, you can read the article I linked to in my reviews.

Of course, that’s not to say that the liquid insulation and the other materials you can use to reduce the noise in your car are in any way bad. Still, we definitely know more about the effects of sound deadening mats than we do about any of the other materials I’ve mentioned. So at least when you get Noico, you’ll know exactly what you’re getting into.

Hopefully, this article has helped you be more informed on the subject of automotive sound deadening materials. No matter which of these materials you end up choosing, your driving experience is sure to improve once you have them put it.
