Insulate your interior from unwanted heat and noise with a Boom Mat thermal and acoustic interior kit. These versatile 3-step packages include plenty of Boom Mat material to cover flat sheet metal and/or door skins, eliminating most structural vibrations, rattles, and squeaks. Next, the can of Boom Mat Spray-On lets you dampen the noise in hard-to-reach areas, like fender wells, the trunk interior, undercarriage, and other body panels. Finally, you can apply the Under Carpet Lite insulating fabric over firewalls and floor boards to resist nearly 85 percent of the heat transferred from engine and exhaust components—while providing additional sound deadening. Boom Mat thermal and acoustic interior kits are economical, easy to install, and work with any vehicle. Choose the coverage size needed for your application.
