Overview:

The DEI Floor and Tunnel Shield II is a high-performance heat control barrier designed to protect your vehicle’s interior and critical components from excessive heat. Featuring a proprietary high temperature black coating and a durable construction, this shield effectively blocks heat transfer from firewalls, transmission tunnels, floors, and other areas prone to heat exposure. Ideal for daily drivers, performance enthusiasts, and restoration projects, it helps maintain cabin comfort and safeguard sensitive parts from heat damage.

With its flexible design and aggressive adhesive backing, installation is straightforward and adaptable to a wide range of vehicle models and configurations. This product is engineered to withstand extreme temperatures, making it a reliable solution for heat management in automotive applications.

Key Features:

The DEI Floor and Tunnel Shield II combines advanced materials and thoughtful design to deliver superior heat protection and ease of installation. Key features include:

• Embossed 10 mil aluminum face bonded to a 1/8" composite glass-fiber core for excellent heat resistance and durability.
• Proprietary high temperature black coating that withstands temperatures up to 1750°F, providing effective heat shielding.
• Peel-and-stick adhesive backing with aggressive, high-temperature pressure sensitive adhesive that holds past 450°F for secure mounting.
• Flexible and easily shaped to conform to firewalls, transmission tunnels, floors, and other complex surfaces.
• Minimal thickness of only 3/16” ensures it fits in tight spaces without compromising clearance.
• Wind and water resistant adhesive backing ensures long-lasting adhesion even in harsh environments.
• Can be trimmed and shaped on-site for custom fitment without special tools.
• Designed to protect interiors and components from heat damage without adding significant weight or bulk.

Construction & Design:

The Floor and Tunnel Shield II is constructed with a layered design that maximizes heat resistance and durability. The embossed aluminum face provides a reflective barrier that deflects radiant heat, while the composite glass-fiber core offers insulation to reduce heat transfer. The high temperature black coating adds an extra layer of protection and a clean, professional appearance.

The adhesive backing is a high-temperature, pressure-sensitive material engineered to maintain a strong bond even under extreme heat conditions. This ensures the shield stays securely in place without the need for mechanical fasteners or additional adhesives.

Its flexible construction allows it to be bent and shaped to fit complex contours such as firewalls and transmission tunnels. While sharp bends may crack the black coating, this does not affect the shield’s performance.

Installation & Fitment:

Installation of the DEI Floor and Tunnel Shield II is simple and user-friendly. The peel-and-stick adhesive backing eliminates the need for drilling, cutting, or special mounting hardware. This makes it an excellent choice for both professional installers and DIY enthusiasts.

Before applying, surfaces should be clean and dry to ensure maximum adhesion. The shield can be trimmed with scissors or a utility knife to fit specific areas precisely. It is important to note that this product should not be applied directly to exhaust components.

• Peel and stick application with aggressive adhesive backing.
• No cutting, drilling, or special tuning required.
• Flexible material conforms to complex shapes for universal fitment.
• Suitable for firewalls, transmission tunnels, floors, and other heat-prone areas.
