Zero Clearance is a diamond faced 3-piece high-tech heat & sound barrier material used on the firewall engine side or under the vehicle on floor/tunnel or exhaust to stop heat. Stop heat before it enters the driver’s compartment. Great for race cars! The Zero Clearance material’s foil side is a 10-mil aluminum facing designed to reflect heat and it is bonded to a 3/16-inch layer of composite fiberglass insulation with a PSA glue added to underneath for faster installation.
