Design Engineering Reflect-A-Gold 12x24 High-Temp Heat Shield Adhesive-Backed Reflective Sheet Made in USA

Premium Heat Reflection for Demanding Applications

Reflect-A-Gold by Design Engineering, Inc. is a high-performance heat reflective sheet engineered to endure extreme temperature environments. It combines a metalized polyamide polymer laminated glass cloth with a high-temperature pressure-sensitive adhesive, delivering a durable, flexible solution for thermal protection in demanding settings.

Capable of withstanding continuous temperatures up to 850°F, Reflect-A-Gold remains lightweight and pliable enough to conform to uneven surfaces. This makes it suitable for automotive components such as firewalls, engine covers, under-hood areas, bulkheads, floors, and even seat bottoms, where radiant heat can impact performance or comfort. The reflective surface helps redirect heat away from critical areas, offering a practical option to reduce heat soak and maintain cooler surroundings in challenging environments.

The adhesive-backed design simplifies installation and removal, enabling a clean, professional finish without specialized fasteners. This feature, paired with UV resistance, supports durability in sunlit environments and extended service in outdoor or marine settings. When you need a reliable barrier that can be trimmed to fit and repositioned during maintenance, Reflect-A-Gold offers practical flexibility for automotive, motorsports, marine, and industrial applications.

Key benefits

• VERSATILE HEAT REFLECTION — Reflects radiant heat away from critical surfaces, helping protect components and nearby materials.
• HIGH-TEMPERATURE PERFORMANCE — Performs in continuous temperatures up to 850°F, helping reduce heat-related wear on substrates.
• STRONG ADHESIVE BACKING — Pressure-sensitive adhesive provides a secure, long-lasting bond to metal, plastic, and composites.
• UV RESISTANCE — Durable in sunlight to maintain appearance and performance in exposed installations.
• RELEASE LINER PROTECTION — Liner rated up to 325°F supports easy handling during installation.

Real-world applications

Consider Reflect-A-Gold for protecting heat-prone zones across industries. In automotive builds, it can shield firewalls, engine covers, and under-hood compartments. In marine and industrial settings, bulkheads, floors, and equipment housings may benefit from a lightweight, reflective barrier. The sheet or roll format lets you tailor coverage for each project without excessive bulk.

Material science and construction

The core construction uses a metalized polyamide barrier laminated to a glass cloth substrate, balancing strength with lightness. The surface is engineered to reflect heat while resisting UV degradation, helping maintain reflective performance after handling. The high-temperature adhesive bonds to metal, plastic, and composite surfaces, reducing the need for mechanical fastening in many installations.

Installation tips

• Prepare surfaces: clean, dry, and free of oils before application.
• Peel away the release liner gradually while pressing firmly to ensure full contact.
• For curved or complex shapes, trim edges and smooth folds to maintain a clean seal.
• Store away from extreme heat or direct solvents to preserve adhesive performance.
