While it performs well in moderately high temperatures, it’s important to verify that your specific application doesn’t exceed its thermal limits.

Unlike traditional caulking or silicone sealants that cure and harden over time, our Butyl Rope remains flexible and does not harden. This flexibility allows it to maintain a seal in applications subject to movement, vibration, or thermal expansion.

No, our Butyl Rope is designed to maintain its shape and does not significantly shrink or expand over time. This stability ensures a long-lasting seal.

It is relatively easily pulled apart and shaped by hand, but can be easily cut to exact lengths with scissors. I also sometimes use hand-held tools to help push it into tight tolerance areas.

ResoNix CCF Decoupler Sheets and Tape are high-quality closed-cell foam products designed to prevent vibrations and rattles between panels in vehicles. They serve as a cushioning layer that isolates panels from each other, reducing noise from panel-on-panel vibration and buzzes, and enhancing the effectiveness of sound barriers. These products feature an automotive-grade adhesive backing, making them easy to install and ensuring they remain securely in place over time.

As of March 2025, Only CCF Decoupler 3S is available in a sheet form. Though, the other versions are still available in our CCF Tape.

The primary differences among the 3F, 3S, and 7S versions are their thickness and firmness. The 3F is a 3mm thick foam that is more firm, suitable for areas requiring additional structural support. The 3S is also 3mm thick but is a softer foam, ideal for tight spaces needing gentle cushioning. The 7S is a 7mm thick soft foam, providing extra cushioning for areas with looser tolerances where more thickness can be accommodated.

Choosing the right version depends on your specific application and the space available. For very tight areas where minimal thickness is essential, the 3S soft foam is recommended due to its thinness and softness. If you need some structural support in tight spaces, the 3F firm foam is a good choice. For areas with more room and looser tolerances, the 7S soft foam offers additional cushioning with its greater thickness.

These products are primarily used to prevent audible rattles caused by panels vibrating against each other in vehicles. Common applications include doors and door panels smaller trim pieces, rear decks smaller trim pieces, dash trim, pillars, and various small and tight tolerance interior panels. They are also used to decouple noise barriers, such as mass-loaded vinyl, enhancing their effectiveness by reducing energy transfer from the vehicle’s body.

The foam acts as a cushioning layer between two surfaces, isolating them from direct contact. By providing a soft and compliant substrate, it absorbs and dissipates vibrations, preventing panels from vibrating against each other. This reduces noise caused by rattling and improves the overall acoustic performance of the vehicle.

Yes, ResoNix CCF Decoupler products are designed to be effective even in tight tolerance areas. The 3mm versions, both the soft (3S) and firm (3F) foams, are particularly suitable for spaces with limited clearance where a thin yet effective decoupling layer is needed.

Installation is straightforward due to the peel-and-stick automotive-grade adhesive backing. Simply cut the foam to the desired shape and size, peel off the backing paper, and apply it to a clean surface. The adhesive is very strong, so it’s important to position the foam carefully, as it will adhere firmly upon contact.

Compression deflection measures the foam’s firmness, indicating how much pressure is needed to compress it by a certain percentage. A lower value means the foam is softer. Compression set refers to the foam’s ability to return to its original thickness after being compressed. Low compression set values mean the foam maintains its shape over time. These properties are important for effective decoupling, ensuring the foam provides consistent cushioning without becoming permanently compressed.

ResoNix CCF Decoupler Foams have a very specific set of these specifications that are perfect for our use case in aftermarket automotive installations. In comparison, pretty much every other foam sold to this market is much stiffer and is not ideal in any way for our uses, but its very cheap and easy to make a lot of profit on for those other companies. Good for them, but we prefer to stick with offering something that puts performance and functionality as the most important aspects of our products :)

An automotive-grade acrylic-based peel-and-stick adhesive is used, ensuring a strong and lasting bond even in demanding automotive environments. This adhesive is designed to withstand temperature fluctuations and maintain adhesion over time. Please note, the adhesive is VERY strong. Be careful and move with intent when installing these products.Can ResoNix CCF Decoupler products handle extreme temperatures?

Yes, these products are engineered to perform across a wide temperature range. The soft foam versions (7S and 3S) are rated for use from -65°F up to 300°F, while the firm foam (3F) is suitable from -40°F to 200°F, all per ASTM D1056 testing standards. This makes them appropriate for various automotive applications where temperature extremes may occur.

Yes, the foam used in these products meets flammability standards for automotive applications. The soft foam versions comply with the FMVSS 302 standard, with a maximum burn rate of 4 inches per minute. The firm foam also passes flammability tests for the specified thicknesses under FMVSS 302.

ResoNix CCF Decoupler products are designed with optimal compression deflection and compression set specifications, making them more effective at decoupling panels than many other foams. Unlike the very popular and common cheap ensolite foams that plague the automotive sound deadening market, which are stiff and very non-compliant, ResoNix foams provide the right balance of softness and structural support. Additionally, being closed-cell foam, they do not absorb moisture like open-cell foams, preventing issues with mold and mildew.

Absolutely. These decoupling products can be used in conjunction with other sound-deadening materials such as constrained layer damping sheets, noise barriers, and fiber mats. By combining different materials, you can achieve comprehensive sound treatment and address various sources of noise and vibration in your vehicle. Read about our suggestions in the ResoNix Buyers Guide article.

Closed-cell foam consists of cells that are completely enclosed and not interconnected, making it resistant to water absorption and providing better structural support. Open-cell foam has interconnected cells that can absorb moisture. In automotive applications, closed-cell foam is preferred because it does not retain water, preventing mold and mildew growth, and provides better decoupling properties.

No, since it is made from closed-cell foam, it does not absorb moisture. This characteristic makes it suitable for automotive environments where exposure to moisture can be a concern. Using closed-cell foam helps prevent mold, mildew, and degradation over time.

The thickness varies depending on the version. The 3S and 3F foams are both approximately 3.2mm thick, suitable for tight spaces. The 7S foam is about 6.5mm thick, providing extra cushioning for areas where more thickness can be accommodated.

Yes, these products are ideal for use in speaker installations to prevent vibrations and rattles. The firm foam (3F) is particularly suitable for sealing speakers to baffles, and sealing said baffles to panels, or for use under heavier components like amplifier racks, providing both decoupling and necessary structural support.

Yes, these products are designed for longevity in automotive environments. The closed-cell foam is resistant to moisture and temperature fluctuations, and the adhesive backing ensures a secure bond. This durability means that once installed, the decoupler will continue to perform effectively over time.

The sheets are available in sizes of 54 inches by 36 inches for the sheets, providing 13.5 square feet of material. The tape versions vary: the 3S soft tape is 3mm thick, 0.75 inches wide, and 40 feet long; the 3F firm tape is 3mm thick, 0.75 inches wide, and 50 feet long; and the 7S soft tape is 7mm thick, 1 inch wide, and 20 feet long.

ResoNix CCF Strips are designed to create a seal between your car’s speakers and the grille openings on the panels that are in front of them. This sealing ensures that all the acoustic energy produced by the speakers is directed into the cabin, rather than being lost behind door or dash panels. By doing so, they maximize the efficiency of your speakers, leading to improved sound quality and increased output within the listening area.
To get more technical, our foam was picked due to its ideal Compression Deflection and Compression Set parameters. The adhesive we use can easily handle the automotive environment without fail. The foam and adhesive are not picked because it was readily available from some supplier on Alibaba. 😊
Finally, the shape of our strips allows for the easiest installation over all other products on all different types of speakers and baffles. With ResoNix, you’re using a quality product made from the best materials made for the job, without any gimmicks such as a minuscule piece of foam advertised as a back-wave absorber.
SOLD AS SINGLE UNITS. 1 quantity includes ONE strip.

While they do not directly improve your speakers themselves, they do improve the environment they are in and create a more suitable installation for them. By coupling the speakers directly to the grille openings, the strips prevent acoustic energy from escaping into unwanted areas behind panels. This focused direction of sound into the cabin reduces resonances and distortions that can occur when sound waves interact with the interior of doors or dashboards. The result is a cleaner, more accurate sound reproduction, allowing you to experience your audio system’s full potential.

ResoNix CCF Strips are made from high-quality closed-cell foam with specific compression deflection and compression set properties. This means they are firm enough to maintain a proper seal yet flexible enough to conform to various shapes and contours found in vehicle interiors. Unlike other products like silicone baffles, which have no chance of creating a proper seal against a door panel, or the Fast Rings, which are made out of open cell foam and defeat their own purpose by letting air travel right through them, these strips provide an optimal balance of support, flexibility, and most importantly their sealing capability for superior performance.

Installation is straightforward due to the strips’ peel-and-stick acrylic-based adhesive backing. First, ensure that the mounting surfaces are clean and free of dust or grease. Then, shape the foam strip around the perimeter of your speaker, pressing it firmly to adhere it to preferably a baffle that is extended beyond the speaker mounting frame, but it can also be adhered directly to the speaker frame itself. Finally, compress the foam against the grille opening or panel to create a tight seal, ensuring that the foam conforms to any contours or irregularities for maximum effectiveness.
These are only 1″ thick for a reason. For optimal performance out of your speakers, they should be as close as possible to the grilles that are in front of them without allowing them to come into contact with said grille or panel. The CCF Strip should have FULL contact to the panel or grille around its entire circumference.

Yes, each strip is 30 inches long and designed with a unique shape that varies in width from 0.75 inches to 0.5 inches. This design allows them to be easily shaped and bent to fit a wide range of speaker sizes, from small 1-inch tweeters up to large 9.5-inch midbass drivers. Their flexibility and length make them suitable for virtually any speaker installation in a vehicle.

The strips are made from a high-quality closed-cell foam specifically chosen for its ideal compression characteristics. This foam provides the right balance between firmness and flexibility, ensuring a good seal without exerting excessive pressure. Additionally, the adhesive backing is an automotive-grade, acrylic-based peel-and-stick adhesive that offers strong, long-lasting adhesion even in extreme temperature conditions commonly found in vehicles.

Silicone baffles, while intended to serve a similar purpose, often fall short because they may not conform well to the contours of grille openings or the panel that is in front of the speaker. Without that proper seal, the sound energy being created by the speaker will not be forced out into the cabin. Fast Rings are made out of open cell foam. Since open cell foam allows air to travel through it, their own material defeats their entire purpose. ResoNix CCF Strips, on the other hand, are made out of closed cell foam, and are flexible enough to adapt to various shapes and provide a proper seal without impeding the speaker’s performance. The closed-cell foam used in these strips does not absorb moisture, making them more durable in automotive environments.

Yes, by creating a tight seal between the speaker and the grille opening, the strips help reduce the amount of acoustic energy that goes behind said panel and prevents it from causing vibrations and rattles in door panels and other interior components. This not only enhances the sound quality but also reduces unwanted noise that can detract from the listening experience. The foam material also acts as a dampening medium when installed optimally due to the light pressure it will put on the panel, further minimizing potential vibrations.

These are now sold by the single unit. Example: an order quantity of “5” will net you 5 individual strips. These used to be sold in pairs, but for inventory tracking purposes, we have changed it to a single unit per quantity, with each measuring 30 inches in length. For most standard car audio installations involving front door speakers, one pair is sufficient. However, if you’re installing multiple speakers throughout the vehicle or have larger speakers that require more material, you may need additional pairs. It’s advisable to measure your specific needs before purchasing to ensure you have enough material.

The strips come with a high-quality, automotive-grade acrylic peel-and-stick adhesive already applied. This adhesive is designed to withstand the harsh conditions inside a vehicle, including temperature fluctuations and exposure to moisture. There’s no need to purchase additional adhesive, making installation more convenient and ensuring a reliable, long-lasting bond.

The materials used in these strips are more than durable enough for automotive settings. The closed-cell foam resists moisture absorption and retains its shape without dry rotting over time, even under constant compression. The adhesive backing is formulated to remain secure under extreme temperatures, both hot and cold, ensuring that the strips stay in place and continue to perform effectively throughout the life of your audio system.

For optimal performance, it’s important to ensure that both the speaker frame and the mounting surface are clean and free of contaminants. When shaping the strip around the speaker, apply even pressure to ensure a consistent seal. Make sure that the speaker and baffle are close enough to the grille/panel to where the CCF Strip will make a proper seal all the way around, and will give some slight back pressure, but not close enough to where the speaker will hit the grille or panel when it is installed and the system is played.

They are proudly made in the United States of America. The materials and manufacturing processes adhere to high-quality standards to ensure that customers receive a reliable and effective product.

Yes, the strips are compatible with both aftermarket and factory-installed speakers. Their flexible design and adhesive backing make them suitable for enhancing the performance of any speaker system, regardless of its origin. Whether you’re upgrading your factory system or installing high-end aftermarket components, these strips can help you achieve better sound quality.

By creating a tight seal between the speaker and the grille opening, the strips prevent sound waves from escaping into cavities behind panels. This containment reduces the interaction of sound waves with interior panel structures, which can cause resonances and distortions. The result is a cleaner, more accurate sound reproduction with reduced unwanted noises, and higher output overall.

       The primary differences among the ResoNix CLD products lie in the thickness of their aluminum constraining layers and butyl rubber layers, which affect their performance and ease of installation. The Mega CLD Squares feature a 12 mil (0.012 inches) aluminum layer and a 120 mil (0.120 inches) butyl layer.
They are the highest performing CLD available, with a Composite Loss Factor of 0.64 at 200 Hz. However, the thicker aluminum makes them stiffer and potentially difficult to work with on surfaces with complex curves.

       The CLD Squares have a 4 mil (0.004 inches) aluminum layer paired with the same 120 mil butyl layer as the Mega version. They boast a CLF of 0.6 at 200 Hz, which is higher than any other product on the market except for the Mega CLD Squares. They strike a balance between high performance, ease of installation, excellent value, while remaining relatively easy to work with even on curved surfaces.

       The Lite CLD Rectangles come with a thinner 3 mil (0.003 inches) aluminum layer and a 45 mil (0.045 inches) butyl layer. While they have a lower damping performance compared to the CLD Squares and Mega CLD Squares, they are the easiest to handle and install, especially on intricate surfaces. All three products utilize the same high-quality butyl formula and aluminum type, ensuring consistent material reliability across the range.

We offer a lifetime guarantee against any manufacturer defects for our ResoNix CLD products.

For further details, including specific certifications and testing results, please refer to our technical documents.

Choosing the right ResoNix CLD product depends on your specific needs and the nature of your application or vehicle. If you are looking for the highest performance possible, the ResoNix Mega CLD Squares are your best option. They excel in damping vibrations on larger panels and are particularly effective in industrial applications or situations involving low-frequency resonance. However, due to the stiffness of their thicker aluminum constraining layer, they are not ideal for areas with complex curves.

If you desire very high performance combined with great value and ease of use, the ResoNix CLD Squares are the most suitable choice. They offer exceptional damping capabilities while remaining easy to install, making them versatile for a wide range of applications without the installation challenges posed by the Mega CLD Squares.

The Lite ResoNix CLD Rectangles are primarily intended for those who have budget constraints that make the CLD Squares or Mega CLD Squares less accessible. The “LITE” designation indicates a different thickness of the butyl layer rather than an emphasis on lightweight applications. While they are more affordable, it’s important to note that, all else being equal, the CLD Squares and Mega CLD Squares are more effective per unit of weight compared to the Lite CLD Rectangles.

Determining how much CLD material you need is a more complex topic than most hobbyists realize. There is no one-size-fits-all answer, as it depends on several factors, including your goals and the specific characteristics of your vehicle or application. For a deeper understanding of how to effectively determine coverage for an automotive application, we recommend reading our ResoNix Buyers Guide Article, where we provide detailed information on this topic. For industrial, commercial, and marine applications, it is best to contact us directly so we can help determine what is best for you.

At minimum, there is no application where I would recommend anything less than 35% coverage. But remember, there is no hard/fast rule on what amount of coverage you should do, and there is absolutely no rule of thumb like many hobbyists seem to think.

Yes, you can mix and match different ResoNix CLD products in one installation. For exact recommendations specific to automotive applications, refer to our ResoNix Buyers Guide.

To properly install ResoNix CLD products for optimal performance, begin by thoroughly cleaning the application surface with isopropyl alcohol to remove any dirt, oil, or contaminants. This ensures proper adhesion of the CLD material. Apply the CLD product firmly to the surface, making sure it fully contacts the panel without air bubbles or gaps. Finish the installation by using the ResoNix Roller to press down the material evenly. It is not necessary to put too much pressure, just enough to make sure there is full contact of the butyl to the panels surface.

If you need to cut the ResoNix CLD Squares, it is best to use shears as it is much safer. But a box cutter is usable when needing to cut out specific patterns. In my experience, I haven’t found a box cutter or razor blade that can cut the Mega CLD Squares. Use shears only for Mega CLD Squares.

For installing ResoNix CLD products, you will need a few basic tools. The ResoNix Roller is provided free of charge with most packages (except for the 5-pack of CLD Squares) to ensure proper adhesion. You will also need shears for cutting the material to size and to cut the extra wax paper provided to create templates for precise fitting. Additionally, it is advised to have isopropyl alcohol and clean rags on hand to thoroughly prepare the surfaces by removing any dirt or contaminants before installation.

You can apply ResoNix CLD materials to virtually any surface in your vehicle that resonates, such as metal body panels, plastic trim, aluminum, or steel. The key is to avoid placing the material in areas that could interfere with any moving parts of the vehicle. To learn more about where and how you can apply this to various parts of our car, see our ResoNix Buyers Guide.

ResoNix Guardian is an adhesive-backed, hydrophobic sound-absorbing pad made of melamine foam and Mass Loaded Vinyl (MLV). It is primarily used to improve midbass performance in car audio systems by absorbing and taking the major brunt of the rear wave in door-mounted midbass driver applications, reducing resonance, and lowering distortion. It also serves as a noise barrier and sound absorber to block external sounds and as a thermal insulator. It is suitable for automotive, marine, industrial, aviation, aerospace, and various commercial applications, thanks to its unique properties that include being fully hydrophobic, durable, heat and fire resistant, and easy to install.

ResoNix Guardian improves midbass performance in car audio systems by addressing two critical aspects of sound control. First, its hydrophobic melamine foam layers absorb the rear wave produced by door-mounted midbass drivers. This absorption reduces the acoustic energy present in the door cavity, minimizing the amount of sound energy that gets converted into mechanical resonance of the door (heard as distortion), and the amount of sound energy that could resonate within the volume of air (remember, volumes of air can resonate on their own separately from the enclosure), which otherwise contributes to distortion. Second, the Mass Loaded Vinyl (MLV) layer takes the brunt of the rear wave’s impact. Instead of allowing this energy to hit the outer door skin directly, which would lead to resonance and audible distortion, the MLV acts as a free-floating, decoupled barrier. This prevents the transmission of sound energy that otherwise would get converted into mechanical resonance of the door structure, effectively reducing unwanted vibrations and improving overall midbass accuracy and clarity.

Yes, it is well-suited for marine applications, including use in engine compartments. Its hydrophobic properties make it fully resistant to moisture, ensuring it can handle the challenging environment without any issues. It effectively reduces engine noise, providing a quieter experience in marine vessels.

Yes, Guardian is the ultimate all-in-one sound absorber, noise barrier, and thermal insulator for camper van conversions or build-outs. Since it provides excellent sound absorption, noise blocking, and thermal insulation, it makes the living space more comfortable and reducing both noise and temperature fluctuations.

     To install ResoNix Guardian inside your car doors, follow these steps:

  1. Clean the Surface:
    Start by thoroughly cleaning the outer door skin using isopropyl alcohol to remove any dirt, dust, or grease. This ensures the adhesive backing sticks properly.
  2. Measure and Cut:
    Measure the area where you want to install ResoNix Guardian, then cut the sheet to the appropriate size to fit your application.
  3. Peel and Stick:
    Peel off the backing from the adhesive. Carefully position it on the cleaned surface of the outer door skin, ensuring the melamine foam layer faces the interior.
  4. Apply Firm Pressure: Press down firmly across the entire panel to ensure proper adhesion. Make sure there are no air pockets or gaps.
  5. Layer Application:
    If you are using ResoNix CLD Squares, apply those first to the metal surfaces before installing ResoNix Guardian for optimal performance.

 
     This process helps absorb the rear wave from midbass drivers and reduces resonance, enhancing your car audio system’s performance.

ResoNix Guardian is hydrophobic, meaning it naturally repels water in its resting state. Water will simply fall off without being absorbed under normal conditions. However, of course if you squeeze it and provoke it to absorb water in say a sink, of course it can absorb water.
