Premium Automotive Sound Treatment Solutions
Available on backorder
Announcement, September 16th, 2022 – ResoNix Fiber Mat products are finally available! Pre-orders are now open, and orders are expected to ship the second week of October. Pre-order sale pricing is only available until October 1st.
ResoNix Fiber Mat 25 is a 25mm (+/- 1mm) hydrophobic polypropylene fibrous mat and is used in aftermarket automotive installations to serve a few purposes. First, to absorb any incoming external noise, such as wind, tire, and road noise. Second, to decouple one panel from another. It can also act as a superior air gap/decoupling layer for a noise barrier such as ResoNix Barrier. And third, it is also an excellent heat insulator, with an R-value of 3.99. Due to the material it is comprised of, it is naturally hydrophobic and is completely mold/mildew resistant. This can be used anywhere in a vehicle without worry. ResoNix Fiber Mat features an automotive-grade adhesive to allow for an easy and lifetime-lasting install. ResoNix Fiber Mat is an absorber that works via the microscopic fibers that convert the passing acoustic energy into mechanical energy (the moving of the fibers) and thermal energy, from the friction of moving through the scattered fibers. It being so soft and plush also offers it to being an excellent decoupler which can be used in doors, rear decks, and anywhere else you can fit it. It is a better decoupler than any Closed Cell Foam on the market as it is extremely soft and compliant and is highly suggested to be used on any larger panels. Due to the nature of the product, we still offer our CCF7 to handle decoupling of small panels, and to spot treat certain areas.
How does it work? Here is an excerpt from our Reference & Information Guide..
First, sound absorption happens when you convert acoustic energy into another form of energy, such as mechanical or thermal. It only makes sense to use a soft, fibrous or porous absorber in a vehicle, so we will stick with how those work. The fibrous materials absorb sound by deforming randomly at a microscopic level as sound passes through. The porous materials absorb sound by creating friction against sound waves as they pass through.
Where should ResoNix Fiber Mat be used?
Transmission Tunnels – Fiber Mat 25 is perfect for absorbing noise that radiates through the transmission tunnel while still fitting behind panels/carpet without issue.
Interior Firewalls – Once again, due to it being able to fit in tight areas, Fiber Mat 25 is the perfect choice to fit on an interiors firewall to absorb noise and block heat from entering the cabin from the engine bay. If Fiber Mat 45 Fits here in your vehicle, use that instead.
Roofs/Headliners – Only if Fiber Mat 45 does not fit in your vehicles roof/headliner – This is going to be the most common area to use for Fiber Mat 45. Use here to absorb and eliminate the largest source of wind noise, the roof. This will also slightly help improve low-frequency transient response in vehicles being built for high-end sound systems.
Remember, every car and every application is different. This is only a list of suggestions based on our experience. What may work best for your situation may be different. It is up to you to figure out what can fit in your vehicles locations. Fiber Mat 45 is always a better choice if it can fit, but the above locations usually have tighter tolerances in which only Fiber Mat 25 will fit within.
