ANTIVIBE sound deadening mat is an anti resonance material designed to stop panel rattle and absorb any structural Vibrations. This is designed to reduce road noise and make the vehicle a nicer environment to be in. The butyl construction of the sheet will not break down in high temperature applications and is extremely dense which adds weight to the sheet. The 0.1mm aluminum top panel of the sheet adds rigidity and ensures the sheet keeps its form while still retaining flexibility. The combination of high performance and flexibility makes ANTIVIBE the perfect choice for ease of installation and end results. Includes: 35 sheets of sound deadener 14.5" x 10.5"
