Design Engineering Reflect-A-Gold heat-reflective adhesive panel 12x24, peel-and-stick, 850°F continuous

Reflect-A-Gold is a 12" x 24" adhesive-backed, metalized heat-reflective panel designed to block radiant heat and withstand continuous temperatures up to 850°F.

This lightweight, flexible panel from Design Engineering combines a metalized polyamide surface laminated to glass cloth with a high-temperature pressure-sensitive adhesive. It’s engineered for demanding thermal environments where radiant heat protection and an easy-to-install adhesive solution are needed. The product’s construction delivers a durable heat shield that resists UV and stays effective across automotive, marine, motorsports, and industrial applications.

How does Reflect-A-Gold protect surfaces from radiant heat?

The metalized face reflects a large portion of radiant energy away from the protected surface while the glass-cloth layer provides mechanical strength and thermal stability. Together they form a barrier that reduces heat transfer from hot sources to sensitive components.

• High-reflectivity metalized polyamide top layer reflects radiant heat.
• Glass-cloth laminate resists heat conduction and abrasion.
• Designed for continuous exposure up to 850°F (radiant heat environments).

What surfaces and applications is this adhesive sheet best for?

The panel sticks to a wide range of substrates, making it suitable for firewalls, engine covers, bulkheads, seat bottoms, floors and fuel-cell areas. Use it wherever a slim, conformable thermal barrier is preferred over bulky insulation.

• Adheres to metal, painted surfaces, plastic, and composites.
• Good for automotive engine bays, racing cockpits, and marine engine rooms.
• Useful for spot shielding on exhaust tunnels, fuel tanks, and firewall penetrations.

How easy is installation and removal?

The pressure-sensitive adhesive backing is protected by a release liner for clean handling and alignment. It applies smoothly to curved or flat areas and can be trimmed to fit irregular shapes; removal is straightforward without heavy residue when done properly.

• Release liner rated to 325°F simplifies placement and prevents contamination.
• Trim with standard cutting tools for custom fitment.
• Designed for peel-and-stick application; removes cleanly in most cases.

What durability and environmental resistance can I expect?

Reflect-A-Gold is built to maintain performance under long-term exposure to heat and sunlight. The material resists UV degradation and preserves both appearance and reflectivity in harsh service conditions.

• UV-resistant metalized surface for extended outdoor use.
• Adhesive chosen for high-temperature holding power and longevity.
• Fabric-reinforced structure resists tearing, vibration, and abrasion.

Who is this product for? Installers, mechanics, fabricators, race teams, boat owners and maintenance crews who need a compact, adhesive thermal barrier will find Reflect-A-Gold especially useful. It’s ideal when space is limited, when a conformable protective layer is required, or when quick, reliable adhesion to varied substrates is necessary. Because it’s made in the USA and available as a 12" x 24" panel, it suits both one-off repairs and professional installations where predictable heat-management performance is critical.
