Dynamat Alternative – Is Dynamat The Best Sound Deadening Material?

Dynamat is great at isolating your car’s cabin from annoying external noises, but is it really the best option for you? There are Dynamat alternatives that can better meet your budget while still working as intended.

I’ve taken an in-depth look at all the products Dynamat make to really get a feel for how comprehensively you can cover your car.

I know from experience that just covering those problem areas isn’t always enough. Making sure that the material you are using is great quality is also important.

There are many people with horror stories, claiming to have spent hundreds of dollars only to get a barely noticeable reduction in sound. The underlying problem is often one of two things.

The quality of the material just wasn’t high enough, or not enough material was used. The lower quality the material, the more you’ll have to use, so it might take a while to find that magic sweet spot.

What are Dynamat Alternatives?

Dynamat is a great overall product with lots of positives. Perhaps the only real con that would dissuade you from buying it would be the price. It can cost a lot to fully cover your entire cabin.

At this point, it’s good to start looking at alternatives to see if there might be some as good, but a little cheaper out there.

HushMat

This product is one of the Dynamat’s main competitors. It is relatively similar in adhesion, sound deadening and thermal insulation.

The material that HushMat is made of is a bit thinner but makes up with it in density.

HushMat is comparable to Dynamat Xtreme range and will do a good sound deadening job.

It’s a little bit cheaper and less popular, but overall people love it.

My favorite part is that you can order a custom kit for your car. This means you won’t buy too much or too little, and your application will be fast and painless.

Cost

Full Car: around $800

Doors Only: around $120

Bottom Line: If you don’t want double layers and are on a budget, this is a great option!

FatMat

FatMat is asphalt based and has a chemical, freshly paved road smell. It doesn’t do well in hot temperatures, so don’t use it if you live in a warm place.

Users love how sticky and pliable it is during application. Although it really doesn’t do well in the heat, it does provide ample sound deadening.

In fact, many say that it’s sound deadening properties far exceed that of HushMat.

This is one of the most popular sound deadening products on the market, and the reason for that is; it’s exceptionally cheap.

At almost half the price of Dynamat, with a good performance, it’s easy to see why this product is so popular.

Cost

Full Car: around $279

Door Kit: around $45

Bottom Line: If you live in a cold area and want to save some money, this is a good one. I’d still suggest something else, considering the degrading nature of asphalt.

Noico

The reviews on this product are actually great. In the end, it still works, and it is cheap, but most agree that you’ll need to you 2 to 4 layers in order to achieve the same effect as Dynamat.

The manufacturer does have a nice range though, with two different weights of product.

It’s a single layer of self-adhesive butyl finished off with aluminum foil.

Cost

Full Car: around $140

Door Kit: around $36

Bottom Line: If you don’t mind spending money on extra layers, this will do the job.

GTMAT

GTMat is relatively unknown in the sound deadening market.

They use a 4-layer system of Butyl, foam and an aluminum foil material.

The makeup is like Dynamat’s, and users seem to love it.

It’s relatively unknown, so there isn’t much information on it, but it looks like it’s a rock-solid option that won’t break the bank.

Added plus it that GTMat has a range of sound dampening products, some which are better for higher temperatures for those in a hot climate.

Cost

Whole Car: around $180

Door Kit: around $46

Bottom Line: I’m really impressed with this product, I feel it hasn’t gotten the attention it deserves. It’s a great, low budget deadener that won’t degrade in the heat. Get this if you don’t want to spend much money.

Siless

Siless makes butyl and foil mats in varying thickness.

Unlike the other alternatives we’ve looked at, they also have a thermal lining material.

Like GTMat, Siless is a relatively unknown sound deadening product. It does the job at a very competitive price.

I feel that the lack of layering will result in a sub-par noise reduction, but this stuff is so easy to apply it’s almost okay. They conveniently tell you how much you need for your size of your car, so you won’t overbuy the product.

They offer lots of thicknesses, which is great for those looking for maximum noise reduction or wanting to keep their car light.

Cost

Whole Car: around $160

Door Kit: around $40

Bottom Line: This brand doesn’t have much of a track record. It looks like it can do the job, but I’d rather spend a few dollars more and go with GTMat.

Dynamat Alternatives Conclusion

Dynamat’s competition is putting up a good fight. They have led the industry for years, but now there are some great alternatives.

If you still want a good quality product and are willing to dish out a bit of money, HushMat is a great middle ground.

Especially for those who are looking to cover their car themselves, the custom car kits make the application faster and easier.

You are still going to spend a lot of money for full coverage though, but you’ll get a result similar to Dynamat at the end of it.

If you really don’t have the budget for a high-end product, then GTMat is the next best thing.

A lot of people prefer FatMat, but I don’t like the idea of asphalt leaking off fumes in my car. GTMat should do the trick just fine at a super low price.

I hope these alternatives have helped to make your decisions easier. Soundproofing your car is really worth it and I guarantee you’ll be impressed by how much more powerful your sound system becomes.

Note: DO NOT USE ROOFING MATERIAL!

I know, all caps are a little aggressive, but roofing material seems to be doing the rounds in all of the forums lately. Even if you just want it to complement your sound deadening, don’t do it.

Roofing materials are not meant to go in cars. They won’t be able to hold up to the harsh changes in temperature or withstand oil and water. The cheap ones are not fire retardant in the slightest and can be a big risk if you get into an accident.

If you still think you know better, consider this; on a hot day, the temperature will rise inside your car and these roofing materials are going to start leaking fumes and adhesive. Only buy stuff that is specifically made for cars.

Review of Dynamat Products

Here is a comprehensive look at all the Dynamat car products. I’ve given you a brief description of the dampeners as per the company website.

One of the great things about Dynamat is that they have an extensive range of products. The deading exterior sound is different for each car. It depends on age, engine type and makes.

Of course, if you want the best protection money can buy, you can go wild and cover your cabin with all the layers possible, but I love that Dynamat gives you a choice. Their products are all designed to work with each other, so you won’t get into any compatibility problems.

Dynamat Xtreme

This is Dynamat’s highest efficiency sound dampening material. The company claims it is their most effective product for stopping noise and vibrations in your car.

It is a thin, super sticky butyl rubber, bonded to an aluminum alloy skin. Formulated with Vector Chemistry, this is Dynamat’s best sound control product.

The product is easy to cut and install, the rubber and aluminum will stretch as you need it without any tearing. It contours well to your car, and will easily stick to any surface without any extra prep.

The material will never drip and its odor free. If you get your car covered by a professional, this is generally what they will use.

Installation:

This product should be applied to any interior fiberglass or sheet metal within your car. You can line your; doors, floor, trunk and roof.

Peel and stick the dynamite to the surface without any extra prep. It comes in a variety of kits which can be used for different areas.

The website suggests you should follow this up with Dynaliner for maximum sound protection

  • Speaker Kit – 2 sheets 10”x10”
  • Door Kit – 4 sheets of 12”x36”
  • Trunk Kit – 5 sheets 18”x32”
  • Hex Pak – 1 sheet of 18”x32”
  • Bulk Pak – 9 sheets of 18”x32”
  • Mega Pak – 9 sheets of 24”x48”

Dynamat SuperLite

This product is like Dynamat Xtreme, but its 30% lighter and 30% thinner with less sound reduction. It is made with the same sticky butyl rubber Constrain Layer Dampener (CLD) but is bonded to bright blue.

This product is lighter, so its sound dampening abilities are sub-par, but it still performs well. It’s a great option for those who want to keep their cars overall weight down.

Installation

Just as simple to install as the Xtreme, Peel and stick the SuperLite version where you need it. It’s a little easier to maneuver because of the weight difference.

You can use it on your doors, trunk, roof, and floors.

It only comes in 2 packs.

  • Tri-Pak – 3 sheets 18”x32”
  • Bulk Pak 12 sheets of 18”x32”

Dynaliner

Dynaliner is a lightweight thermal insulator intended for use on top of Dynamat Xtreme. It is made to insulate your car, reducing heat while resisting oil and water.

It is made from cell rubber, a material that packs thousands of cells close together to reduce air infiltration.

The material is a soft, self-adhesive that is resistant to crushing or tearing.

It has the highest heat blocking abilities available in a single layer, and when combined with Dynamat Xtreme, it doubles the total thermal resistance ability.

Installation

Like the other Dynamat products, this is a peel and stick adhesive sheet. It’s designed to be applied over Dynamat Xtreme and can be placed in your; roof, firewall, floor, quarter panels, doors, and hood.

It comes in 3 different weights and it is suggested that you use the thickest one you can.

  • 1/8″ Thick Dynaliner – 1 sheet of 32”x54”
  • 1/4″ Thick Dynaliner – 1 sheet of 32”x54”
  • 1/2″ Thick Dynaliner – 1 sheet of 32”x54”

DynaPad

Dynapad is designed to further dampen any outside noises. It is heavy, one pound per square foot mat that is 3/4″ thick.

It is made of a four-layer composite barrier and uses Dissimilar Layer Insulating technology.

This is further enhanced by two layers of acoustic sound soaker foam and is covered by an oil and water-resistant poly facing.

This pad will focus on removing low-frequency sounds from your exhaust and other traffic.

Installation

Unlike other products, this is intended to be used as an underpad car mat. Place it on the floor of your cabin and the rear deck for optimal results. Dynapad only comes in one size.

  • 1 sheet of 3/4″ thickness, measuring 32”x54”

It is intended for use over a layer of Dynamat Xtreme (Add Dynaliner for the best experience).

Hoodliner

Hoodliner is designed to drastically reduce the amount of noise your car’s engine outputs. It is made from a 3/4″ acoustic sound soaker foam with a reflective, reinforced aluminized skin.

The acoustic foam works by converting sound waves into heat energy. The liner has a combination of open and closed cells that dissipate the sound waves.

The balance of open and closed is the trick here, as too many of the one would result in less sound dampening.

The foam is cast in sheets, assuring balances absorbance throughout the entire panel. The aluminized skin is cleanable and is oil and water resistant to a 97% heat reflection.

Although this product was designed for the hoods of cars, it’s useful in isolating any engine sounds. For example, it could be used to dampen the sound of a boat’s motor or personal generator

Installation

Hoodliner has a high tack pressure sensitive adhesive that allows for easy peel and sticks applications. It only comes in one size

  • 1 sheet of 3/4″ thickness, measuring 32”x54”

It is recommended to be used in conjunction with Dynamat Xtreme, and if a black finish is desired, it can be covered with Dynaliner.

Dynaplate

Dynaplate is a solid but flexible aluminum sheet. Great to use when you don’t want to bulk you interior up, 2 sheet application provides sound dampening comparable to the Xtreme.

It’s self-adhesive, and you can easily use for difficult to cover spaces and maximize your soundproofing.

It is very thin and light, but still strong and you can use it on floors, roofs, woofer enclosures and anywhere else you can think of.

It is specifically engineered for SPL competition rules and power classes of dB Drag racing, USACi, IASCA, and IdBL.

The two-layer setup will reinforce structural panels and prevent ballooning common on SPL cars.

Installation

Dynaplate is self-adhesive and easy to apply and shape to your specification. It can be used to cover entire panels or patch up hard to reach areas. You can only buy it in one standard pack:

  • 3 sheets measuring 24”x 30”

DynaTape

A pretty straightforward accessory, this is a great tool to help you give your project a professional finish.

The tape is made of 2mm thick aluminum and can be used with other Dynamat product to seal seams and attach wiring.

It’s also great at containing unwanted butyl migration and neatening up mistakes.

  • The tape is 1.5” wide and 30ft long

What Do Users Think of Dynamat

So, after looking at the wide range of interchangeable products, you have to think how they actually hold up. Do they really help absorb outside sounds in your car?

And is it worth it to layer like they suggest (the company suggests you go for a layer of Xtreme, Dynaliner, DynaPad, and Hoodliner for the ultimate protection)?

I looked at a ton of reviews on a variety of sites, trying to understand why some people love it, and others not so much.

It turns out it’s really easy to spot why some users have issues. I came up with a few pros and cons that should shed some light on you.

Pros

  • Its fire-retardant and will stand the test of time. A point-blank blowtorch in the same spot for 10 seconds didn’t even leave a mark
  • It’s an industry standard and most professional places will be able to apply it to you
  • There are so many products, you can really customize your proofing
  • It is undoubtedly good quality
  • No chemical fumes
  • Oil and water resistant
  • Improves rigidity
  • Can be used for multiple purposes
  • You don’t need a crazy amount to get good results

Cons

  • Some people feel it doesn’t reduce sound enough. But, that’s usually because they haven’t covered the car enough.
  • It doesn’t play well with others, so don’t use other products in conjunction with it
  • It can set you back a good amount of money, this stuff doesn’t come cheap
  • If you don’t cover the seams, the butyl coating might start seeping out
  • It can add a lot of weight to your car

Cost

Dynamat is expensive, and you can add any number of layers to make it even more so. Here is a rough estimate of what it will cost you to do an average car.

Whole Car: $1300

Doors Only: $300

In Conclusion

As you can see, there are many other alternatives to Dynamat, and all of them are cheaper. But just how much cheaper can you go, and is it worth the drop in quality?

Dynamat is definitely the most expensive product on the market. However, it remains the top choice among professionals.

I believe this is because it really is the highest quality product that money can buy. It won’t break or get damaged, and it’ll improve the rigidity of your car’s structure.

Dynamat offers such a large range of products, so you’ll be able to choose exactly what you need.

The hood liner is a great product that I haven’t seen anywhere else. Its specifically made to deaden the sound of engines (diesel owners will know how important this is) and won’t be a fire risk.

On the topic of fire, Dynamat is one of the few products that are truly heat resistant. It can stand a lot of heat and provides a great insulation layer.

One of the downsides to Dynamat is that you must cover a lot of surface area. It’s suggested that you start by covering at least 30% to see any reduction in sound. The cost can quickly add up.

On the flip side, when a car is fully covered, the dampening effect is pretty amazing. Is it worth it? If you want the best audio quality out of your system, then you bet it is!
