Design Engineering Reflect-A-Gold heat reflective adhesive sheet 12" x 24" — high-temp, UV-resistant thermal barrier

Reflect-A-Gold is a 12" x 24" adhesive-backed, high-temperature reflective sheet engineered to reflect radiant heat and provide a durable thermal barrier for extreme environments.

Made in the USA by Design Engineering, Reflect-A-Gold combines a metalized polyamide film laminated to glass cloth with a high-temperature pressure-sensitive adhesive to protect components exposed to intense heat. This lightweight, flexible sheet resists UV, handles continuous temperatures up to 850°F, and installs quickly on metal, plastic, and composite surfaces. It’s supplied as a 12" x 24" sheet (also available in rolls) for use in automotive, motorsports, marine and industrial applications where radiant heat control and surface protection matter.

How does Reflect-A-Gold cut down radiant heat on hot components?

The metalized face reflects a large portion of radiant energy away from the protected surface, reducing heat transfer by radiation rather than relying solely on thickness. Its glass-cloth backing adds mechanical strength and tear resistance so the reflective layer stays intact under vibration and flexing.

• Metalized polyamide surface for high emissivity reduction.
• Glass-cloth lamination resists abrasion and tearing.
• Works where space limits the use of bulky insulation.

Will the adhesive hold up on engine bays and hot panels?

The pressure-sensitive adhesive is formulated for prolonged adhesion at elevated temperatures and bonds well to common substrates found in engine compartments and marine installations. For easier handling, the adhesive is protected by a release liner rated up to 325°F, allowing positioning before exposing the adhesive for final placement.

• High-temp pressure-sensitive adhesive for long-term grip.
• Release liner rated to 325°F for safer installation handling.
• Adheres to metal, composites, and many plastics when surfaces are clean.

How durable is the sheet against weather, UV, and mechanical wear?

Reflect-A-Gold is UV resistant to slow degradation from sunlight exposure and engineered to resist the abrasion and flexing common in automotive and marine settings. The combination of a metalized film and reinforced cloth backing produces a lightweight yet rugged barrier that retains reflective performance over time.

• UV-resistant face to preserve reflective properties outdoors.
• Glass-cloth core provides tear and puncture resistance.
• Lightweight construction minimizes added mass where weight matters.

How do I apply and remove the 12" x 24" sheet safely?

Clean the surface of oil, dirt, and loose coatings before applying; position the sheet while the release liner is in place, then peel and press firmly to activate the adhesive. Removal is straightforward—heat and steady peeling reduce residue, and any remaining adhesive can be cleaned with appropriate solvent or cleaner.

• Surface prep: degrease and dry for best adhesion.
• Install: align with release liner in place, then peel and press.
• Remove: apply moderate heat and peel; clean residue with solvent if needed.

Who is this for? Reflect-A-Gold 12" x 24" is aimed at mechanics, fabricators, motorsports teams, marine technicians, and industrial maintenance pros who need a compact, professional-grade thermal barrier. If you’re protecting firewall sections, fuel cells, engine covers, under-hood panels, seat bottoms, or floor areas where radiant heat is an issue, this sheet offers a high-temperature, adhesive-backed solution that balances ease of installation with long-term durability.
