During the entire silencing of your vehicle, three different types of material can be applied, to help you achieve the best possible results. The products can be layered, where each one has different properties and operates in different frequency ranges.
(It is important to remember that all of these layers may not be practical for all users and installation projects, however with these steps in mind you should be able to plan the best solution for your needs.)
- STEP 1: Damping Mats
For the first layer, you can use butyl-aluminium mats, which eliminate noise created by metal body elements. It absorbs vibrations and low frequency noise.
- STEP 2: Closed Cell Foam
For the second layer we advise closed cell foam. Materials such as rubber foam and PPE ECO foam, block the passage of medium and high frequency road noise and improve thermal insulation, this way adding even more comfort to your vehicle.
- STEP 3: Acoustic Foam or Felt
