48in x 72in Thermo Guard FR Two Side Foil

The 48in x 72in Thermo Guard FR Two Side Foil is a professional-grade thermal barrier designed for serious engine builders and performance mechanics who require effective heat management in tight underhood spaces. This double-sided reflective shield addresses the critical challenge of controlling radiant heat from headers, exhaust manifolds, and turbocharger installations without compromising clearance or airflow.

Constructed with fire-resistant (FR) rated materials, the Thermo Guard Two Side Foil features reflective foil coating on both surfaces to maximize radiant heat rejection while maintaining a lightweight profile. This dual-sided design is essential for applications where heat sources surround the component, such as wrapping intake manifolds or isolating fuel lines from ceramic-coated headers. It is engineered to withstand ambient temperatures exceeding 300°F, ensuring durability and effectiveness in demanding environments.

Ideal for both naturally aspirated and boosted applications, this foil provides the thermal isolation that professional shops rely on. Whether you're building a street performance engine or protecting sensitive components from extreme underhood temperatures, the Thermo Guard FR Two Side Foil is a reliable choice for high-performance builds where weight is a critical factor.
