Sound Barrier

Most road noise originates under a vehicle by the wheels coming into the contact with the pavement. Ziebart’s Sound Barrier creates an insulated layer of protection under your vehicle to help reduce road noise while protecting your vehicles underbody from moisture, dirt, grime, and salt, which can lead to rust.


  • + Reduce road noise originating from under the vehicle
  • + Four times thicker than undercoating to help dampen vibration
  • + Covers critical areas to prevent moisture, chemicals, and salt from reaching the metal, causing rust to form
  • + Professionally applied and will not affect any areas that should not be treated, such as brakes, exhaust, and drive shafts
  • + Abrasion resistant and self-sealing to protect against small road debris
