DEI Form-A-Shield Heat Barrier Sheet

Fits Most Models

50519

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 protect sensitive components and improves overall engine bay conditions while retaining more heat within the exhaust system for enhanced performance.

Its pliable construction allows it to conform to a wide variety of shapes and configurations, making it suitable for most vehicle models. Whether you are upgrading your performance setup or seeking to manage heat in a daily driver, the Form-A-Shield offers durable, chemical-resistant protection that stands up to demanding environments.

Key Features:

The DEI Form-A-Shield combines advanced materials and thoughtful design to deliver superior heat management. Key features include:

• Withstands direct heat exposure up to 1400°F and beyond, providing robust thermal protection.
• Constructed from 10 mil dimpled aluminum bonded to a high-temperature rated basalt thermal barrier material for excellent insulation.
• Extremely pliable design allows easy shaping and application to complex exhaust components and tight spaces.
• Durable and resistant to oil, chemical spills, and environmental contaminants for long-lasting performance.
• Can be applied directly to hot surfaces, effectively lowering under hood temperatures and protecting nearby components.
• Fastening options include straps, clamps, or DEI Locking Ties—no adhesive backing required for high-heat areas.
• Can be combined with DEI Adhesive Spray for application on cooler surfaces to serve as a heat barrier or reflector.
• Designed to insulate anywhere near the path of exhaust pipes, reducing radiant heat transfer efficiently.

Construction & Design:

The Form-A-Shield features a layered construction with a 10 mil thick dimpled aluminum outer layer bonded to a basalt thermal barrier core. This combination provides a lightweight yet highly effective heat shield that reflects radiant heat while resisting damage from oils and chemicals commonly found in engine bays. The dimpled aluminum surface enhances durability and flexibility, allowing the sheet to conform tightly to irregular shapes such as turbo housings and exhaust bends.

Unlike heat wraps or coatings, this sheet can be applied directly to hot surfaces without adhesive backing, ensuring reliable performance in extreme temperatures. The design prioritizes ease of installation and adaptability, making it a practical choice for a wide range of automotive applications.

Installation & Fitment:

The DEI Form-A-Shield is designed to fit most vehicle models and exhaust configurations. Its pliable nature allows it to be shaped and trimmed to suit specific applications such as headers, manifolds, turbo housings, and downpipes. Installation is straightforward and does not require adhesives on hot surfaces; instead, secure the shield using straps, clamps, or DEI Locking Ties for a firm hold.

For non-hot areas, DEI Adhesive Spray can be used to attach the shield as a heat reflector or barrier. This flexibility ensures you can customize heat management throughout your engine bay without permanent modifications.

• No cutting, drilling, or special tuning is required for installation.
• Can be fastened with common automotive clamps or DEI’s proprietary locking ties.
• Installation instructions are included to guide proper application and maximize heat protection.
