Dynamat vs FatMat: Differences and Similarities

What Are They Made Of?

Both products have different makeups that give them their distinct characteristics. Dynamat is made of butyl rubber, coated with aluminum which allows the product to stretch easily. Being heat resistant and odorless, you can safely use it even in hot weather.

FatMat, on the other hand, is made using asphalt and prides itself as one of the best sound deadeners you can find. Due to its asphalt based composition, it’s not fit for use in areas where the weather gets hot. In high temperatures, the FatMat can melt and cause a mess, with the emission of an obnoxious smell.

Effectiveness

DynaMat is very effective and valuable at keeping the noise outside mainly because of the thickness that makes it act as a sound barrier. The thickness allows it to reduce noise by up to 10 decibels which is great.

It‘s heat resistant due to the butyl based composition, so you can make use of it in both hot and cold weather conditions (it can stay odorless at temperatures up to 2400F; 115.60C).

Its density and thick nature make it more durable as it’s not easily torn apart so what you get is a soundproof product that is also durable. You can be sure of great noise cancellation as you use this product.

Fatmat is also great at keeping noise out thereby improving the quality of sound indoors due to its asphalt based composition. The thinner structure of this product makes it easier to install when compared to Dynamat but that also reduces the noise cancellation property.

A huge drawback to the use of Fatmat is its odor production when used in hot weather. So it’s restricted to use in cold environments.

When it comes to the overall effectiveness of both products, Dynamat is the preferred choice as it more efficiently cancels noise due to its thickness, and can be used in both hot and cold weather conditions.

Ease of Installation

Dynamat needs good preparation before installation which includes proper cleaning of the surface. If you’ll be using it in your car for instance, then you would need to have good knowledge of your car.

This is to help you with the location and amount of the material to put where necessary. These factors together with the fact that Dynamat is thick and more difficult to cut makes it not as easy to install as FatMat. Though it’s not too difficult still.

The thickness is to make the material durable and make the product a very good soundproof choice.

FatMat, on the other hand, is thinner and easier to install when compared to Dynamat.

Made with asphalt material, FatMat melts when exposed to high temperatures, so you have to be careful when using heat to install this sound deadener.

Being a self-adhesive product, you need to prevent the material from seeping out during installation, and also do not let the material stick to itself because it will be impossible to separate them without destroying it.

So in terms of installation, it’s a bit easier to install FatMat than it is to install Dynamat.

Mass per Area and Dimensions

Dynamat has a mass per unit area of 0.4 lbs/ft2, and dimensions of 18” x 32” x 0.067” giving it good area density and allowing it to better cancel out external noise.

This is more effective than that of FatMat with mass per unit area of 0.266 lbs/ft2 and dimensions of 18” x 40” x 0.05” implying that Dynamat does a better noise canceling job than FatMat. 

Thickness

The thickness of the sound deadeners affects their effectiveness in keeping noise out. The thicker the material, the better it would be at stopping the outside noise from coming inside.

Dynamat with a thickness of 0.067” does a better job at soundproofing than FatMat with a thickness of 0.05”.

So if you are looking for a product with good enough thickness to cancel out a good amount of the outside noise, your best choice would be Dynamat.

Price

Being that Dynamat has better effectiveness, and can be used in both hot and cold temperatures without fear of melting or producing odor it’s only normal for it to cost more than FatMat.

So if you are a shopper on a budget, you may want to go for FatMat instead.
