DEI Form-A-Shield Heat Barrier Sheet
Universal Fitment – Fits Most Models
10516
Overview:
The DEI Form-A-Shield Heat Barrier Sheet is a versatile thermal protection solution designed to withstand direct heat exposure up to 1400°F. Ideal for automotive enthusiasts and professionals alike, this heat shield can be applied to exhaust headers, manifolds, turbo housings, and downpipes to significantly reduce radiant exhaust temperatures. By lowering under hood heat, it helps improve overall engine bay conditions while retaining more heat within the exhaust system for enhanced performance.
Its pliable design allows it to conform to various shapes and configurations, making it suitable for a wide range of vehicles and applications. Whether you are a daily driver looking to protect sensitive components or a performance enthusiast aiming to optimize thermal management, Form-A-Shield offers durable, reliable heat insulation.
Key Features:
Form-A-Shield combines advanced materials and thoughtful design to deliver superior heat protection. Key features include:
- Constructed from 10 mil dimpled aluminum bonded to a high-temperature rated basalt thermal barrier material for excellent heat resistance.
- Capable of withstanding direct heat exposure exceeding 1400°F, making it suitable for extreme exhaust system temperatures.
- Extremely pliable and flexible, allowing it to form tightly around complex shapes such as headers, manifolds, and turbo housings.
- Durable and resistant to oil, chemical spills, and environmental contaminants commonly found in engine bays.
- Effective at reducing radiant heat transfer, lowering under hood temperatures and protecting nearby components.
- Can be applied directly to hot surfaces without degradation or loss of insulating properties.
- Installation is simple using straps, clamps, or DEI Locking Ties; no adhesive backing is included for direct high-heat applications.
- Compatible with DEI Adhesive Spray for use on cooler surfaces as a heat barrier or reflector.
Construction & Design:
The Form-A-Shield sheet features a layered construction combining a 10 mil dimpled aluminum outer layer with a basalt-based thermal barrier core. The dimpled aluminum surface reflects radiant heat, while the basalt material provides excellent insulation against conductive and convective heat transfer. This combination ensures maximum heat resistance and durability in harsh automotive environments.
The sheet’s flexibility allows it to conform to irregular shapes and tight spaces, making it ideal for wrapping exhaust components and other high-temperature areas. Its chemical and oil resistance ensures long-lasting performance even in demanding under hood conditions.
Installation & Fitment:
Form-A-Shield is designed for universal fitment and can be applied to most vehicle models and exhaust configurations. It installs easily without the need for adhesives on hot surfaces, using straps, clamps, or DEI Locking Ties to secure it in place. For non-hot areas, DEI Adhesive Spray can be used to attach the sheet as a heat reflector or barrier.
No cutting, drilling, or special tuning is required to install Form-A-Shield, making it a straightforward upgrade for improved thermal management.
- Apply directly to exhaust headers, manifolds, turbo housings, and downpipes.
- Secure with straps, clamps, or DEI Locking Ties (included separately).
- Use DEI Adhesive Spray for cooler surfaces if needed.
