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.
