Kilmat vs Dynamat: Differences and Similarities

Materials They Are Made Of

Both Kilmat and Dynamat are mainly composed of butyl rubber with metal backing. Butyl rubber is a synthetic rubber product that has a wide range of uses including its use in the production of tires and the inner layer of basketball.

It’s a dense material, making it perfect for the absorption of vibrations that attempt to pass into your car.

Even though both are made of the same material, Dynamat as a high-end product that contains more expensive components where possible to ensure that it’s of top quality throughout.

The backing material is to ensure durability as it’s tear-resistant. Kilmat also has a backing material that makes it durable.

Ease of Installation

Kilmat comes with an indicator that assists you to properly install it in your car. The only preparation you need before installation is to clean the surface and make sure it’s free from grease.

Being that it’s not too thick, you can easily cut it into the desired sizes and shapes for various parts of your car on which you wish to install the mat. Then peel off the adhesive and carefully place the mat on the surface. To make it smooth and more permanent, run it over with a roller and that’s all.

The preparation before installing Dynamat is the same as that for Kilmat but it’s not as easy when it comes to the installation itself. Being thicker it’s harder to cut. 

Kilmat is more user friendly even if you are a beginner with no experience and so when it comes to ease of installation, Kilmat is the winner.

Mass per Area and Dimensions

Kilmat has a mass per unit area of 0.34 lbs/ft2 and dimensions of 15.7” x 9.8” x 0.05” as opposed to the 0.45 lbs/ft2 and 18” x 32” x 0.067” of Dynamat.

This means that Dynamat allows you to cover more, is thicker, and has better area density than Kilmat which makes it better at quieting unwanted noise.


The thicker the material, the better it will be at canceling noise and vibrations. Kilmat has a thickness of 0.05” which is pretty good and you can be sure that it will effectively improve the acoustics of your car as you drive.

Dynamat is thicker, measuring 0.067” and so it will have a better capacity to absorb vibrations and cancel noise.


Dynamat is made to ensure nothing less than the best quality, and so it’s made using more expensive materials. The backing material is one such and it gives it durability so that you can use it for long without having to replace it.

It’s also made with greater thickness when compared to other sound deadening products, giving you better performance in canceling vibrations and noise.

Kilmat is a good budget option. It helps you keep the vibration and noise out but not as good as Dynamat and one of the reasons is because of the difference in thickness.

So when it comes to effectiveness, Dynamat wins Kilmat.

Thermal Insulation

Kilmat is a product that only offers you noise cancelation and nothing else. Dynamat, on the other hand, has thermal insulation properties in addition to the noise cancelation function it provides so that you can keep both heat and noise from the engine away.


Dynamat is high end and due to the quality of materials it‘s made of, its thickness, and also its performance, its high cost, when compared to Kilmat, is no surprise.

If you can afford it, then it’s a good investment and worth it, but for those on a tight budget, Kilmat is the cheaper option amongst the two.

Kilmat Review

Kilmat is a brand that has made a name for itself as a good sound deadener especially for those who cannot afford the Dynamat products.

Kilmat is made with butyl rubber and has a metal backing to help with the durability of the product.

Butyl rubber gives it the characteristic of vibration absorption and sound cancellation, making it a worthy purchase.

Even though it’s made with Butyl rubber, it’s thin and so its action is limited as thickness plays an important role in soundproofing.

In all, it’s a great product and a good affordable option for Dynamat.
