Design Engineering Reflect-A-Gold high-temp adhesive heat shield panel 12 x 24 in — reflective, flexible to 850°F

Reflect-A-Gold 12" x 24" is an adhesive-backed, metalized high-temperature heat shield panel engineered to reflect radiant heat and resist continuous exposure up to 850°F.

Built from a metalized polyamide polymer laminated to glass cloth with a high-temperature pressure-sensitive adhesive, this 12" x 24" panel from Design Engineering delivers a lightweight, flexible barrier for hot zones where protection matters. The sheet is designed for easy trimming and bonding to metal, plastic, and composite substrates, and it ships with a release liner rated for 325°F to simplify handling during installation. Suitable for automotive, motorsports, marine and industrial use, Reflect-A-Gold offers professional-grade reflectivity and durability in demanding thermal environments.

How does Reflect-A-Gold reduce radiant heat in tight spaces?

The metalized surface reflects radiant energy away from components, lowering the heat load on sensitive parts without adding significant bulk. Because the product is flexible and conforms to contours, it makes close-contact installation on awkward shapes easier than rigid shields.

• Metalized polyamide surface reflects radiant heat effectively.
• Laminated glass cloth adds tear resistance and structural stability.
• Thin profile preserves clearance in confined engine bays and compartments.

Can it stay in place under extreme temperatures and outdoor exposure?

Yes: the high-temperature pressure-sensitive adhesive is formulated to adhere securely at elevated temperatures and to resist UV-driven degradation so the bond and appearance remain stable over time. The release liner is rated to 325°F to protect the adhesive during handling and initial heat exposure.

• Adhesive rated for high-temp continuous exposure and strong bond strength.
• UV-resistant facing retains reflective performance outdoors.
• Release liner simplifies peel-and-stick installation and heat endurance.

What parts and applications are best suited for this 12" x 24" panel?

The sheet is sized to cover medium areas or to be cut into custom shapes for specific components. Typical uses include firewall patches, seat bottoms, engine covers, bulkheads, and local patches on fuel cells or under-hood surfaces where radiant heat is concentrated.

• Firewalls and bulkheads for driver/passenger protection.
• Under-hood zones: manifolds, turbo housings, and engine covers.
• Marine engine compartments and other confined hot areas.

How do you install and maintain Reflect-A-Gold panels?

Installation is straightforward: clean the surface, trim the sheet to fit, remove the release liner, and apply with firm pressure. For long-term performance, inspect the edges and re-seat or replace panels if adhesive fails or the facing becomes compromised.

• Clean substrate of oil, dirt, and loose paint before bonding.
• Trim with scissors or a utility knife for a custom fit.
• Apply firm pressure and allow time for adhesive set under ambient heat cycles.

Who is this for: Reflect-A-Gold 12" x 24" is aimed at professionals and serious enthusiasts—automotive technicians, race teams, marine mechanics, and industrial maintenance crews—who need a thin, adhesive-backed radiant barrier that endures very high temperatures. If you require a field-trimmable, durable reflective shield for firewalls, engine bays, fuel cell areas, or any compact hot spot, this panel offers a practical balance of reflectivity, adhesion, and flexibility backed by Design Engineering quality.
