Leading the Market in Sound Deadening
What makes ResoNix the best automotive sound deadening material on the market?
Look, I get it. In the world of Amazon Prime instantly gratifying our every desire for pennies on the dollar, why pay for something that looks the same but has a much higher cost? I’m guilty of it as well. Look for some random product that works for what I need at that moment, hit the one-button purchase, and expect it the next day, all while costing practically nothing.
Well, we have to all be real with ourselves here. Not even talking about sound deadener, but since when is some typical amazon-sold product the best available? Pretty much never. Even products sold elsewhere are very questionable these days and we are plagued with markets full of cheap products that are meant to last just long enough while being as profitable as possible for the company selling them. They’re usually only “good enough” to satisfy our instant gratification lifestyles that we are so unfortunately used to now.
But if you wandered far enough down the rabbit hole in the pursuit of sound quality to find us, then chances are you aren’t looking for something sub-par, or even average. What you are most likely looking for is the best overall performance, and the best overall value. If you are reading this, there is a good chance you already know that we offer the best products available. If you don’t know that, well, let’s dive into it.
Industry-Leading Products
Product Overview
ResoNix CLD Squares
Made in the USA
Produced from start to finish under our direction
Butyl Formula
The highest performance, no filler butyl formula
Aluminum Layer
We use a higher grade and temper of aluminum

Our ResoNix CLD Squares, as with everything else we make, is made right here in the USA. What makes these better than any other constrained layer damper on the market is a few simple things. First, the butyl formula. This is the main factor of what sets apart one CLD from another is the formula that makes up the viscoelastic butyl rubber.
These viscoelastic properties of the butyl layer are what allow a CLD to effectively constrain panels and reduce resonance, while the aluminum layer provides a reference for the layer to adhere to and work against. Now, not all butyls are created equal. Heck, not all sound damping products even use butyl. There are many different types you can start with, but also additives that help modify the properties to achieve a certain goal. In our case, we start with a very high quality butyl and only have functional additives, additives that will increase the performance in in resonance control and temperature resistance of the butyl we use.
Many other manufacturers and brands see a different type of opportunity here. Instead of formulating the best product they can, they use a cheaper butyl with a cheaper adhesive, and load it with non-functional additives in order to add more volume. This allows for a higher yield of their butyl layer, but one that is much less effective. But to them, who cares? They are well aware that 99% of the automotive sound deadener consumers have no idea that there is a difference in performance, let alone a large difference so why not just make the spec sheet’s stated thickness (which is what most people think makes a good CLD) look good while also lowering the overall cost? Win-win for them, but it’s a losing battle for the end user who is none the wiser.
Now, we also have the aluminum layer. Again, most just think thickness is the only factor to performance here. The truth is, there is more to it than that. For our CLD Squares, we use a higher grade and temper of aluminum that provides superior stiffness and damping over cheaper grades of aluminum. Some cheaper brands don’t even use aluminum as their constraining layer, and will instead go even cheaper and use aluminized mylar. So to sum it up, ResoNix is using the best aluminum constraining layer we can get without causing a diminishing return on overall cost to the end user, coupled with the very best butyl formula we could make for our uses.

ResoNix Fiber Mat - Black Edition
Made in the USA
Produced from start to finish under our direction
Fully Synthetic
Naturally mold and mildew resistant
Durable
Doesn’t fall apart and holds together over time

Our ResoNix Fiber Mat products pretty much speak for themselves, and only mostly compete against themselves. As of right now, we are one of a few offering a product like this to end users. The only thing is, ResoNix Fiber Mat is the only one made here in the USA, and is made out of a vertically lapped material that is not only much finer for better absorption performance, but is also the only one that is fully synthetic and is naturally mold and mildew resistant. The others on the market utilize cotton, or mixtures with cotton which will not fare well long term in the automotive environment.
The only competitor that is close to our Fiber Mat products is 3m Thinsulate, which has fibers that are not as fine and give our Fiber Mat a large advantage in the acoustic absorption department. It also doesn’t come with a peel and stick adhesive, so installing it is not as easy or clean, and is a melt-blown product, which is notorious for having no rebound once compressed, which reduces its absorption and insulation performance even further. Our Fiber Mat products also cut easily and leave a clean edge that doesn’t fall apart, and holds together over time.
ResoNix Guardian
Made in the USA
Produced from start to finish under our direction
Customizable Size
Can custom cut to size for any application
100% Waterproof
Uses a Hydrophobic Melamine foam

ResoNix Guardian is also another product that doesn’t have much competition. There is one other product that competes with it in the aftermarket automotive space, which is actually another product that we sell. It is not ours, but we do offer it to those that want it. The differences between the two mostly comes down to the foam. With the other product, it has the same thickness of layers, the same mass loaded vinyl layer, etc., but its foam is a standard polyurethane “acoustic” foam, and is treated on the sides to prevent water from soaking in.
There are two problems here. First, while the sides may be treated to prevent water absorption, the pleated face is not, and still allows water to soak in. Frankly, this is what caused us to come out with Guardian. The second problem is polyurethane foam is good, but not great for acoustic absorption. ResoNix Guardian takes care of both of these issues. Instead of a cheap polyurethane foam, Guardian uses a Hydrophobic Melamine foam for the two foam layers.
Melamine foam out of the gate is a better acoustic absorber than polyurethane foam, and also has MUCH better heat insulation properties. It also can be treated to be hydrophobic throughout its entire volume so no water has any chance of effecting it.
We make it in 12” x 12” squares so you can custom cut this product to size for whatever application you may have and achieve a neat and uniform look while achieving full coverage. As you can see, we also sell its direct competitor product for the same price. Being the direct maker and supplier of Guardian helps keep overall cost down so you are getting a much better product for the same price.
We now also a more economic solution for door cavity sound absorbers. If Guardian is a bit out of your price range, check out our ResoNix Lockout.
ResoNix Barrier
Made in the USA
Produced from start to finish under our direction
Twice as Heavy, Fraction As Thick
2 lb/ft² for 2× performance at 25% thickness of MLV
Flexible Material
Easily shape it to any contour you want

ResoNix Barrier is pretty simple and is straightforward in its performance benefits. A standard noise barrier in the aftermarket automotive market is going to be 1/8” thick 1lb per square foot mass loaded vinyl. While MLV is cheap and readily available, it is NOT easy to work with, especially considering all of these newer vehicles have much tighter tolerances and will not agree with the fact that MLV isn’t very flexible, bendable, or moldable. It can only be easily bent in one direction, and is relatively thick and cumbersome, so you can forget about using this in complex shaped areas and in most newer vehicles.
This is where Barrier steps things up. Barrier, instead of being a very stiff and stubborn mass loaded vinyl, is 1/32” sheet lead that is encapsulated in foam. It is twice as heavy per square foot, so it is much more effective, yet it is 4x thinner than MLV, and is actually flexible, bendable, and moldable. You can easily shape it to whatever contour you want, and it will hold its shape and allow you to easily reinstall your interior with ease. It is also the only noise barrier on the market that features the decoupling layer on both sides keeping it truly isolated from the vehicle and panels around it, and has two options for foam thickness for various applications.
ResoNix CCF Decouplers
Made in the USA
Produced from start to finish under our direction
Compression Tested
Ideal Compression Deflection for automotive decoupling use
Built To Last
No degrading or peeling for decades

ResoNix CCF Decouplers include CCF 7S, 3S, and 3F, and are probably our most simple and straightforward products that we offer. Now, most foams on the automotive aftermarket are a basic and common ensolite type foam. It is stiff, not very compliant, and doesn’t have great compression set and compression deflection specs for our needs. We need something soft that will provide cushion, but still have some structure to it unlike a typical eggcrate foam. This combination is what achieves the best isolation properties while keeping it easy to install with the most coverage and contact possible. Our CCF Decoupler 7S and 3S have an ASTM D1056 verified compression deflection spec of 1 psi. This is very compliant and will allow it to be very useful and very flexible in our world of sound treating vehicles. Our CCF Decoupler 3F product is stiffer, and intended to be used for more heavy-duty gasketing applications, but is still softer than nearly all foams found in the aftermarket.
ResoNix Butyl Rope
Made in the USA
Produced from start to finish under our direction
Butyl Formula
Use only a pure high performance butyl
Durable
Doesn’t fall apart and holds together over time

ResoNix Butyl Rope follows the same principles that all of our other products do. Basic concepts, but executed perfectly. While there are many other Butyl Rope type products on the market, none have the longevity, heat resistance, and adhesion that ours does. While I have had other butyl rope products dry out after sitting on the shelf for a few months, the original samples that I still have from March of 2019 are still as good as new to this day, 4 years later.
