Heatshield Armor 1/2 thk x 18 in W x 4 ft L

The HeatShield Armor 1/2 inch thick x 18 inch wide x 4 foot long heat shield from HeatShield Products is a multi-layer aluminized cloth radiant barrier rated for continuous exposure up to 1800 degrees Fahrenheit. Designed for thermal protection in high-heat environments, this flexible heat shield reflects radiant energy away from sensitive components, equipment, and personnel in industrial, automotive, and tactical applications where engine heat, exhaust systems, or radiant heat sources pose operational or safety risks.

At half-inch thickness, this HeatShield Armor product delivers robust thermal protection while remaining flexible enough to wrap around pipes, headers, or irregular shapes without cracking or losing integrity. The aluminized multi-layer construction reflects heat rather than absorbing it, which keeps surrounding materials cooler and reduces heat soak into adjacent systems. The 18-inch width and 4-foot length provide 6 square feet of coverage per unit, allowing users to protect extended runs of exhaust piping, radiator hoses, or engine bay components. Weighing just 2.78 lbs, the material is lightweight enough for vehicle installations without adding significant mass.

This heat shield is used in automotive engine bays to isolate exhaust manifolds and headers, in off-road and tactical vehicle builds to protect fuel lines and electrical systems from underbody heat, and in industrial equipment where radiant barriers prevent heat transfer to adjacent machinery or work areas. The 1800-degree rating makes it suitable for contact with hot exhaust systems without degradation. Users installing HeatShield Armor typically secure it with high-temperature fasteners or adhesive-backed spacers to maintain an air gap between the shield and the heat source, maximizing reflective performance.

HeatShield Products is recognized for manufacturing thermal barriers that meet OEM and aftermarket standards. The aluminized cloth construction is durable against vibration, moisture, and thermal cycling, making it reliable for both street and off-road vehicles, as well as stationary industrial applications. For operators, mechanics, and technicians specifying heat protection, HeatShield Armor delivers verified thermal control at a straightforward price point.
