ResoNix CCF Decoupler Sheet - Soft CCF with Adhesive Backing (13.5 Square Feet)

ResoNix CCF Decoupler 3S is a 3mm thick closed cell foam with an automotive-grade peel-and-stick backing. It’s perfect for tight-tolerance areas that need decoupling, cushioning, or gasketing to eliminate rattles or seal air gaps without adding bulk. Ideal for clean, low-profile installs where space is limited. Sheet size: 36″ x 54″ (13.5 sq ft).

What Sound Deadening Materials Should I Use?

Product Description

       ResoNix CCF Decoupler is a thin, soft Closed Cell Foam, often referred to as CCF, or sound deadening foam, coming in at 3.2mm thick for the 3S, and 6.5mm for the 7S. These are used to decouple tighter tolerance panels from one another and act as a decoupler for noise barriers, such as Mass Loaded Vinyl or lead sheet. CCF Decoupler products feature an automotive-grade adhesive that makes it easy to install and ensures a lifetime-lasting hold.

       The primary purpose of CCF Decouplers are to prevent audible rattles caused by two panels vibrating against each other. It also reduces the amount of energy transferred from the body of the vehicle to your noise barrier, making the noise barrier more effective. This works by providing a soft, compliant substrate for the panels to transfer their energy into, rather than vibrating against a hard surface. 

       Essentially, the closed-cell foam provides a cushion of support between vibrating panels. What separates our closed cell foam products from the rest is primarily how soft and compressible it is while still maintaining high resilience to the automotive environment.

       Info regarding some older models that we used to offer: The S in 7S/3S stands for Soft, while the F in 3F stands for Firm. 7S is to be used where tolerances are relatively tight, yet you need decoupling. CCF3S and CCF3F is for where you have a tighter tolerances. CCF3F is still softer than most other foams on the automotive sound treatment market, but is just firmer than our CCF3S and CCF7S. CCF 3S is extremely soft and very thin and is for the areas that are of tightest tolerances in a vehicle.

       CCF sound deadening foam should be used as a spot treatment to eliminate panel-on-panel vibration noise in areas such as doors/door panels, rear decks, C, B, and C Pillars, and other various interior panels, as they are the main offenders of this type of noise. When doing aftermarket speaker installs, constrained layer damping alone may not be sufficient to achieve the desired results, as it does not decouple panels. This is where our CCF, Fiber Mat, Guardian, and other products come into play.

Compliant for a Reason

Most people don’t realize this type of product needs to be compliant enough to actually decouple panels.

Details

Compliant for a Reason

       The job of a decoupling foam is to isolate panels and allow energy to dissipate rather than transfer from one surface to another. To do this correctly, the foam must be compliant. The problem is, many installers and even brands don’t understand this. They assume stiffer foam is better, when in reality, stiffness defeats the purpose of a decoupler. Our ResoNix CCF 3S and 7S are specifically tuned to offer very low compression deflection, which is exactly what’s required for proper vibration isolation. This is based on real-world performance and proper material science.

Made for Automotive Sound Treatment

Designed specifically for isolating trim and supporting noise barriers in real vehicles.

Made for Automotive Sound Treatment

       Most generic foams used in the sound deadening market are not designed for cars. They are pulled from unrelated industries where mechanical or thermal insulation is the primary goal, not acoustic decoupling. ResoNix CCF products are purpose-built for this application. They are optimized for panel fitment, vibration behavior, and environmental exposure seen in real automotive use. Whether you are eliminating door panel buzz or improving the performance of a noise barrier like MLV or lead sheet, our CCF is actually engineered to perform that task, not just rebranded from some cheap supplier catalog.

Tuned for the Right Mechanical Behavior

Formulated with the proper density, rebound, and flexibility for its job.

Details

Tuned for the Right Mechanical Behavior

       ResoNix CCF Decoupler foams are not just picked for thickness and feel. They are tuned for performance. Density, rebound speed, and flexibility are carefully chosen so the foam compresses under light panel pressure but springs back into shape without permanent deformation. This balance ensures consistent decoupling performance, reliable fitment, and minimal long-term change. Poor-quality foams often either compress and stay flattened, or are so stiff that they pass vibration straight through. Ours are engineered to land squarely in the sweet spot.

Dialed-In Compression Characteristics

Compresses and rebounds correctly for reliable decoupling performance.

Details

Dialed-In Compression Characteristics

       Compression deflection describes how much force is needed to compress the foam. For a decoupler to work properly, it must compress easily enough to form a seal between panels without adding stress, but not collapse completely and stop functioning. ResoNix CCF foams are tested to ensure they hit the ideal values. Most competing foams are way too stiff, or they compress once and never return to shape. Ours retain their behavior over time and continue to function exactly as intended.
