Kilmat vs Dynamat: Which is Better?

Most people spend hours in their car every week, and driving can even be a pleasing or therapeutic activity. However, when there's too much noise from your car, metal rattling, engine noise, traffic buzz, and other types of road noise, driving becomes hectic and stressful. That’s definitely not how you want your daily commute to work to be.  

Putting sound-deadening materials in your car is the best solution to this problem. If you don't know anything about sound deadeners (and even if you already know a thing or two), this article will be helpful for you. 

When you’re trying to find the best sound deadening brand, you’ll notice there’s a wide variety to choose from. To help you out with finding the best soundproofing mats for your car, we’ve written a comprehensive review that compares two very popular sound deadeners: Kilmat and Dynamat.

Either one will help keep sound out of your car and give you a better driving experience. But is one truly better than the other? Read more to find out. 

What Is a Sound Deadener?

A sound deadener blends vibrations and adds weight to panels. This in turn makes your vehicle more silent by decreasing vibrations or noise from outside the car. 

A sound deadener can go a long way in increasing your level of comfort in your car. 

Other benefits include: 

  • Promotes privacy
  • Increases concentration while driving
  • Reduces noise both internally and externally
  • Blocks out noise from tires and exhaust
  • Reduces rattling
  • Improves the sound from your car stereo
  • Make conversations in the car better 
  • Promotes a peaceful and quiet environment

There are a lot of brands that promise the luxury experience of a fully soundproof car but don't live up to it. And many that advertise this feature are ridiculously expensive and not worth the price. 

Kilmat and Dynamat are two popular and high-quality sound deadening brands, with the latter being less expensive. They both provide a comfortable and valuable experience, but which one is better?


Kilmat provides vehicle soundproofing at an affordable price and doesn't weigh a ton. Typically, its mass per unit area is 0.34 lbs, weighs 0.5 lbs per square foot, and it has a thin width of 0.05 inches. 

It is made from butyl rubber, which is a foil that has a metal backing. Butyl rubber is a dense material that’s perfect for blocking noise vibrations from entering your car.

Even though rubber tends to have a noticeable smell, Kilmat is completely odorless. Kilmat sound deadening mats come in different sizes so that you can choose the one that best fits the size of your vehicle. These sizes include: 

  • Kilmat 80 mil 25 sq ft car sound deadening mat
  • Kilmat 80 mil 36 sq ft car sound deadening mat
  • Kilmat 50 mil 50 sqft car sound deadening mat

Pros of Using Kilmat Sound Deadening Mat

  • It’s affordable but still high-quality.
  • It’s effective in reducing noise around the car.
  • It’s made with quality materials.
  • It’s easy to install.
  • It’s odorless.
  • It comes with sheets that are easy to install.
  • It can be installed internally and externally.
  • It can be used in hot weather.

Cons of Using Kilmat Sound Deadening Mat

  • Kilmat is thinner, and therefore not very durable.
  • It doesn't come with rollers.
  • The sheets are stiff, which makes the installation process take longer. 


On the other hand, Dynamat sound deadener is much more popular and a go-to option for most people. Dynamat sound deadeners are not limited to cars alone, but can be used in offices, homes, etc.

Dynamat is also made from odorless butyl rubber like Kilmat but instead has aluminum backing. Butyl rubber is a synthetic material that is also used in making tires.

Kilmat vs Dynamat

A big bonus from Dynamat is that it stops sounds from inside your car from escaping. Dynamat has a 0.45 lbs for mass per unit area, 0.067-inch thickness, and a dimension of 18 x 32 x 0.067 inches. 

The types of Dynamat soundproofing material used include:

  • Dynamat Dynaliner and Dynapad
  • Dynamat Xtreme
  • Dynamat Hoodliner

Pros of Using Dynamat Sound Deadener

  • It is very effective in canceling out noise and buzz away from the car.
  • It is made with quality materials.
  • It’s long-lasting.
  • You can customize the sizes you want your sheet to come in.
  • It doesn't produce any odor during usage.
  • The aluminum backing ensures durability and high quality.
  • It can be used in any weather.
  • It is heat resistant.
  • It is stretchy and doesn't easily tear.
  • It doesn't require heating before it can be installed.

Cons of Using Dynamat Sound Deadener

  • It is not beginner-friendly, and it’s difficult to install.
  • It is expensive.
  • The roller has to be purchased separately.

Comparing Kilmat vs Dynamat Sound Deadeners


Kilmat is made from high-quality material that makes it last for a long time, and it has a backing metal that makes it durable.

Dynamat is similarly made from good materials, but the Dynamat materials are more expensive than Kilmats. Dynamat can be used for a long period of time without replacement.

Because Dynamat is thicker than Kilmat, we would consider it to be more durable. 


Even though both of these products are made from rubber, neither have an offensive smell that would stink up your car. 


Compared to other sound deadeners, Kilmat is very budget-friendly. Dynamat, on the other hand, is more expensive than Kilmat. 

Ease of Installation 

Kilmat is beginner-friendly. It comes with an indicator that assists you during the installation process so you know if you’re on the right track. This makes your work much easier and less time-consuming.

The glue on Kilmat is made to stick firmly. The mat comes with the glue already on it, so all you have to do is clean the surface, cut out your desired size with a pair of scissors from the sheet, peel the adhesive, and stick it to the area. You can then either smooth it over with a roller or your hand. If you want to use a roller, you have to purchase it separately. 

The adhesive on the sheet is also odorless.

Kilmat sheets are thin and don't come in big sizes, which makes them manageable and easier to work with. There are 34 sheets in a pack.

Dynamat, on the other hand, is thicker and more difficult to cut. When installing this product, be ready to break a sweat. Dynamat sound deadeners come in made-to-measure packs which make installment easier. 

Unlike Kilmat, Dynamat isn't beginner-friendly and does require a little time and some patience. 


They are both made from butyl rubber, but Dynamat is thicker and generally more effective and longer-lasting. The thicker material and aluminum backing both contribute to Dynamat being more durable. 

Kilmat is not as thick as Dynamat. A thicker sound deadener absorbs more noise and is more effective.

Thermal Insulation

Dynamat isn't just limited to canceling out noise, it also offers the luxury of keeping both the noise and the heat from the engine away from your car’s interior.

Kilmat only helps with sound deadening.

7. Usage

Kilmat is limited to being used in cars, vans, trucks, etc, but Dynamat can be used in homes, offices, on floors, doors, under-hoods, etc.


Kilmat and Dynamat are two of the most popular mats for vehicle soundproofing. They both have their strong points and weaknesses, all of which should be taken into consideration when choosing which product to buy.

From this comparison between Kilmat vs. Dynamat, it is clear to see that the latter is the better choice. It reduces noise in the car and is more durable.  

Dynamat isn't just popular, it is top-quality and specifically made to make every user's experience more comfortable. Although it is more expensive than other brands, its features and value make it worth it.

If you're not on a budget, go ahead and purchase a Dynamat sound deadener.

However, Kilmat can easily be used alternatively for those who want great sound dampening but cannot afford Dynamat. It performs similarly to Dynamat, though it will probably not last as long. 

No matter which one you choose, you’ll walk away with an effective method for keeping sound out of your car so you can enjoy your time behind the wheel more!
