Reflect-A-Gold Heat Barrier 1.5 x 30ft

The Reflect-A-Gold Heat Barrier 1.5 x 30ft from Design Engineering is a professional-grade thermal shield built specifically for automotive engine compartments, exhaust systems, and high-heat applications. Whether you're upgrading a street rod, tuning a performance car, or managing underhood temperatures in a tight engine bay, this reflective barrier protects critical components from radiant heat damage. Heat reflection is non-negotiable in modern performance builds—factory layouts weren't designed for upgraded headers, superchargers, or turbochargers that push temperatures well beyond stock specifications.

Constructed with a gold-faced reflective surface, the Reflect-A-Gold Heat Barrier uses proven metallurgical technology to reflect up to 96% of radiant heat away from fuel lines, wiring harnesses, plastic reservoirs, and air intake systems. The 1.5-inch width makes it ideal for wrapping exhaust manifolds, turbo housings, transmission cooler lines, and intake plenums where precision coverage matters. The 30-foot roll length provides ample material for comprehensive protection across multiple components without waste, and the flexible textile backing ensures conformability around curves, bends, and irregular engine bay geometry. Unlike bulky foam insulation, this barrier maintains a low profile while delivering measurable temperature reduction—typically 200–400°F surface temperature drop depending on application and heat source intensity.

Mechanics and enthusiasts rely on this product for both new builds and retrofit installations on turbocharged, supercharged, and naturally aspirated performance engines. The 1.5-inch roll width suits tight spaces where wider barriers prove impractical, making it perfect for wrapping individual headers, fuel lines running near hot surfaces, or custom intake manifolds. Installation requires only basic tools—scissors or a utility knife and high-temperature adhesive—and takes roughly 30 minutes per major component. Compatible with all gasoline and diesel engine types, the barrier withstands continuous exposure to temperatures exceeding 400°F and maintains its reflective properties indefinitely when properly installed and secured.
