The DEI Reflect-A-GOLD 12 inch by 24 inch sheet is an advanced adhesive heat shield designed to protect vital automotive components from extreme temperatures. Constructed from a metalized polyimide laminated to lightweight glass fiber cloth, it offers exceptional heat resistance and durability for applications such as firewalls, transmission tunnels, engine covers, and seat bottoms. Its minimal thickness of just 0.0065 inches ensures it fits into tight spaces without requiring significant clearance. The high-temperature pressure-sensitive adhesive bonds securely to surfaces, providing a reliable thermal barrier that won't lift off over time. This product is suitable for environments where continuous temperatures can reach up to 800°F and resists UV degradation for long-term performance, making it ideal for underhood and interior heat protection.
