04248 Zero Clearance / PSA - Heat and Sound Barrier

42″ x 48″ – Foil/PSA (Pressure-Sensitive Adhesive)

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 the floor/tunnel or exhaust to stop heat. Stop the heat before it enters the driver’s compartment. Great for racecars!

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 underneath for faster installation. Material is rolled for easy shipping. Seal edges for outside weather with silicone….

Some products work well together like a Buddy system. Using Koolmat on the interior floor, firewall, tunnel, and Zero Clearance on the inside of the sides of the tunnel, under the tunnel top, will prevent heat from entering the interior, stopping heat.
