Heat Screen Radiant Mat w/Adhesive 36 x 40

The Heat Screen Radiant Mat with Adhesive 36 x 40 from Design Engineering is a professional-grade thermal barrier designed to protect vehicle components from radiant engine heat and exhaust system temperatures. As a mechanic, you know that underhood heat management is critical for preserving fuel lines, wiring harnesses, battery components, and custom modifications—especially in high-performance builds where engine bay temperatures exceed factory specs. This self-adhesive heat screen solves the problem by reflecting harmful radiant energy away from sensitive areas, extending component lifespan and improving reliability in aggressive driving conditions.

Constructed from 0.060-inch thick aluminized plastic and fiberglass composite, the Heat Screen Radiant Mat operates on proven reflective principles—the aluminized surface bounces radiant heat rather than absorbing it, maintaining cooler underhood temperatures without adding bulk or weight. The self-adhesive backing eliminates fasteners and provides quick, permanent installation on any clean surface, making it ideal for wrapping intake manifolds, turbocharger housings, fuel injector rails, and firewall protection. At 36 x 40 inches, this single mat covers substantial surface area, allowing you to protect multiple critical zones or create custom-fitted barriers tailored to your specific engine bay layout and modification strategy.

This heat barrier is essential for turbocharged and supercharged engine builds, fuel-injected performance cars, and any vehicle with relocated or upgraded exhaust components where OEM heat shielding falls short. Custom fabricators, motorsports enthusiasts, and shop technicians rely on Design Engineering's Heat Screen to maintain factory component tolerances while maximizing horsepower gains—without sacrificing durability. Installation is straightforward: clean the target surface, peel and apply the adhesive mat, and trim excess material with a utility knife. The flexible fiberglass construction conforms to curved surfaces and complex geometries, making it compatible with virtually any underhood application where thermal management matters.
