1/14/2023 Product Update: ResoNix Fiber Mat now comes with press sealed edges all around.

 

ResoNix Fiber Mat 25 is a 25mm (+/- 1mm) hydrophobic polypropylene fibrous mat featuring an automotive-grade peel-and-stick adhesive on one side, 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?

Fiber Mat 25 Installation Suggestions: 
Note: Fiber Mat 45 is always better to use if it can fit. 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 if the suggested locations have a tighter tolerance than normal, it is suggested to use Fiber Mat 25 will fit properly.  
 
  • Doors – In between door panels and the inner door skin as a decoupler, replacing commonly used closed cell foam to eliminate pesky rattles from the doors. It also acts as an absorber here for outside wind/tire/road noise, as well as astray midbass frequencies from door-mounted speakers. If Fiber Mat 45 Fits here in your vehicle, use that instead.
  •  
  • Rear Decks – In between rear deck panels and the metal underneath. This serves as an excellent decoupler here to eliminate rattles which cause muddy and distracting bass from trunk-installed subwoofers. If Fiber Mat 45 Fits here in your vehicle, use that instead.
 
Pillars A, B, and C Pillars can all benefit from the installation of ResoNix Fiber Mat. These are very common areas that not only have a ton of rattles that need to be decoupled, but are also very common areas that are the source of audible wind noise that Fiber Mat will absorb. 
  •  

Floors – If applicable, the Fiber Mat 25 can be an excellent choice to use an absorber on the floor since it is able to be compressed thin enough to fit underneath most vehicles carpets to absorb outside noise entering through the floor. It is also an EXCELLENT decoupler/air gap for a noise barrier. If you can fit it, using this between the floor and a noise barrier such as ResoNix Barrier will greatly improve the barriers ability to block outside noise.  

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. 

 
 
 Things to note.
 
  • . Hydrophobic and mold/mildew resistant. Water is of no concern for this product.
  •  
  • . Cutting the product with heavy duty scissors and will usually create a sealed edge. Open edges are fine, but if agitated, this can cause fibers to pull out of the opening. Do NOT cut with a razor blade or box cutter. It will not cut cleanly. Scissors only. 
  •  
  • . Use INSIDE of doors on outer door skins at your own risk. 
 
. This product absorbs sound best when left uncompressed. Having it compressed in certain tight areas is fine, but do not try to stuff areas as tight as possible. It wastes product and decreases the overall performance.
