Dynamat SuperLite is a high-efficiency sound damping material used to stop noise and vibration in your automobile. It is the same sticky butyl rubber Constrain Layer Damper (CLD) as Dynamat Xtreme in a 30% thinner, and lighter form. Use Dynamat SuperLite when you need to quiet your car without adding too much weight. The thin butyl rubber layer is bonded to a gleaming blue, 2 mils thick aluminum alloy. As CLDs work better the thicker they are, Dynamat SuperLite is not as effective a sound damper as Dynamat Xtreme, but using patented VECTOR™ Chemistry, SuperLite is still able to outperform other brands of damping material.
