5mm constrained layer damping material uses mass loading to lower panel resonance and absorb structural vibrations, converting them into low level heat. Stop those nasty rattles, eliminate road and outside noise, insulate your vehicle and dramatically improve the sound of your car audio stereo system. Our vibration damping products are a polymeric based damping material with a supercharged adhesive. With an Aluminum surface and a unique military-grade composition, it has been proven to be extremely efficient at the conversion of vibration to thermal energy. Vibro Solution is very flexible which is very important to the installer, as it allows it to properly adhere to a contoured panel. This 5MM product is made for the top of the firewall down and around the transmission tunnel. Vibro Solution sound and vibration damping are already the choice of many car audio companies.
