ResoNix CCF Decoupler Sound Deadening Foam Sheets – 13.5 Square Feet


ResoNix CCF Decouplers are closed cell sound deadening foam with a peel-and-stick automotive grade adhesive backing. This is the perfect product to use for very small and tight tolerance areas with little room for resistance that still need decoupling, cushion, or gasketing to prevent rattles or air leaks.

Self Adhering Sound Deadening Foam

       ResoNix CCF Decoupler products are thin, soft Closed Cell Foams, often referred to as CCF, or sound deadening foam, coming in at 6.5mm (+/- 0.25mm) thick for the 7S, and 3.5mm thick for 3S & 3F. It is used to decouple tighter tolerance panels from one another and act as a decoupler for a noise barrier, 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 CCF7S/CCF3S from CCF3F is its firmness. 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 to eliminate panel-on-panel vibration noise in areas such as doors/door panels, rear decks, and 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.

       We have designed our multiple offerings of closed-cell foam to have the ideal properties to provide the best decoupling layers in the industry. We have found the perfect balance of providing a thick enough, yet soft or firm enough material to properly decouple panels, while also being easy to work with due to their natural compliance, and longevity in automotive environments. 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.

       Note: Since the release of our Fiber Mat product line, we only recommend using CCF Decoupler products for decoupling small and/or very tight tolerance areas where the Fiber Mat products cannot fit. For areas where you can fit Fiber Mat, it will be better than any of our other CCF products.
