Buying Guide: Factors to Consider Before Buying
Before we dive into the buying guide details, I quickly want to depict the various areas where you can apply these materials:
1. Material Type
Some of the automotive sound-deadening materials are made using thick fiber material to absorb all the vibrations from the floor of the vehicle.
Foams are also used to help reduce echoes in the interior of the car by preventing reverberations of sound waves.
Some sound deadening products contain asphalt which is the main cause of the odor in the interior of the cabin. I’d recommend you go for asphalt-free products since they can be harmful to the human body.
Mats containing the viscoelastic polymer layer along with aluminum can effectively baffle low-frequency noises.
Butyl based sound deadening products like Noico are harmless and effective in reducing unnecessary noises.
2. Sound Isolation Type
Automotive sound deadening compounds can either serve as sound-absorbing material or act as sound blockers.
HushMat 10200 Ultra Black Foil Door Kit is an excellent product to attenuate noise due to road vibrations and distortions. There are mats that are very efficient at reducing the low-frequency noises and structural sounds.
3. Thickness & Size
The thicker the material is, the better is its noise-blocking performance. Hence, it’s essential to find a mat with a sufficiently thick material.
Proper shape and size of the pieces of mat are also a must so that all the parts of the vehicle can be properly covered to attain the main objective. Some brands like HushMat also sell them in sheets. You can cut the material of FatMat to easily get perfect sized pieces.
4. Heat resistance
Not all sound-deadening materials can tolerate high temperatures. It is common that the parts of the vehicles get heated up as they run, hence, you need to purchase such a product that will not fail in excessive heat.
Fortunately, all the products that I have mentioned earlier will function perfectly in such high-temperature conditions.
5. Are Rollers Included?
Rollers are needed to properly install the products to deaden the sound. But all brands do not provide you with rollers along with the main product.
The FatMat has an installation kit included in the package that contains rollers.
7. If the Material is Odor-free
The main ingredient which is responsible for the odor in the sound deadening compounds is asphalt. The bad smell can really make your rides very uncomfortable.
Not all automotive sound deadening products are oil-resistant. It is always advised to go for a sound deadening material that is resistant to oil else, the functioning of the material may get disrupted when exposed to oil.
Some of the best oil-resistant products in our list are Noico Sound Deadening Mat and FatMat Self-Adhesive Rattletrap Sound Deadener.
Frequently Asked Questions
1. Peel and Seal vs Dynamat: Should you use Roofing/Flashing materials for soundproofing?
In my opinion, no.
Peel and Seal is another cost-effective alternative to Dynamat but it is not so effective in its operation. It is a self-adhesive instant waterproof repair and flashing material.
Also, the Peel and Seal is that is an asphalt-based product. Asphalt has been scientifically proven to be extremely harmful to human health. It can cause major health issues like headaches, skin rash, sensitization, throat and eye irritation, cough, and skin cancer.
Therefore, I recommend you go for non-asphalt products like Noicio and Hushmat.
Here is a table to depict the differences between Dynamat and Peel and Seal.
|Dynamat||Peel & Seal|
|Price||> $4/sqft||< $2/sqft|
|Asphalt in Mixture||No||Yes|
|Sag Temp Rating||> 240 °F||< 240 °F|
|Nominal Thickness (mil)||67||45|
2. GTmat vs Dynamat
GTmat is another strong competitor to Dynamat. It is engineered with low-odor asphalt and contains higher heat resistance properties. The product comes in two rolls. They are 25 sqft in length and 16 sqft in width.
Besides this, in the package are also included 2 GTmat decals, a biodegradable degreaser, and a roller to help you in installing the product easily.
The only difficult part is that you will have to constantly apply pressure while using the roller during the installation process.
Here’s a quick comparison between the two:
|Price||> $4/sqft||< $2/sqft|
|Asphalt in Mixture||No||Yes|
|Sag Temp Rating||> 240 °F||> 240 °F|
|Nominal Thickness (mil)||67||50/80|
3. What Can You Use Instead of Dynamat?
Dynamat is a well-reputed brand known for its effectiveness as sound deadening material. The only downside is that it’s a bit pricey.
Fortunately, there a number of budget-friendly and effective alternatives.
From my experience, I’d recommend you go for Hushmat or Noicio.
6. Is Soundproofing Your Car Worth It?
With the help of a good quality sound deadener, you can reduce unwanted road noises that will prevent you from getting distracted while you drive.
You can enjoy clear communication with people sitting next to you or on the phone without yelling at them to make yourself audible. You can also enjoy listening to the stereo without having to increase the volume to compensate for the noises created by the different parts of the vehicle.
The Bottom Line
In my opinion, Noico Sound deadening mat is the best Dynamat alternative for most people. It’s 80 mils in thickness and comes with a vibro-dampening layer of butyl that offers perfect noise insulation.
The FatMat is also 80 mil in thickness and features a super-stick adhesive material that’s effective even at higher temperatures, thanks to its aluminum coating.
