DEI Floor and Tunnel Shield II Adhesive Backed Sheet
Fits Most Models
50502
Overview:
The DEI Floor and Tunnel Shield II is a high-performance thermal barrier designed to reflect and insulate against intense heat sources commonly found in automotive environments. Ideal for enthusiasts, racers, and daily drivers alike, this shield protects critical vehicle areas such as firewalls, transmission tunnels, floorboards, and fuel cells from excessive heat transfer. By limiting heat exposure, it helps safeguard expensive components and enhances occupant comfort inside the vehicle.
Lightweight and versatile, the Floor and Tunnel Shield II also provides sound deadening and guards against track and road debris. Its adhesive-backed design ensures a secure, long-lasting installation, making it a practical solution for heat management in a wide range of applications.
Key Features:
Engineered for superior heat protection and ease of use, the Floor and Tunnel Shield II offers the following benefits:
- Embossed 10 mil dimpled aluminum face for excellent heat reflection and increased rigidity
- 1/8" composite glass-fiber core providing lightweight thermal insulation
- High-temperature pressure-sensitive adhesive backing that withstands temperatures past 450°F for reliable adhesion
- Overall thickness of only 3/16" allowing for installation in tight clearance areas
- Withstands heat up to 1750°F on the aluminum face, making it suitable for extreme heat zones
- Multi-surface compatibility including metal, aluminum, carbon fiber, and plastic
- Acts as a sound deadener and barrier against track and road debris
- Peel-and-stick application for quick, secure installation with no special tools required
- Aluminum side must face the heat source for optimal performance
- Durable, patented finely woven glass-fiber backing enhances strength and longevity
Construction & Design:
The Floor and Tunnel Shield II features a robust construction combining a dimpled aluminum surface bonded to a composite glass-fiber core. This design delivers exceptional thermal insulation while maintaining a lightweight profile. The embossed aluminum face improves heat reflection and structural rigidity, ensuring the shield holds its shape and effectiveness over time.
The adhesive backing is formulated to resist high temperatures and maintain a strong bond even in demanding environments. At just 3/16" thick, the shield can be easily trimmed and shaped to fit custom applications, making it ideal for use in confined spaces such as transmission tunnels and floor pans.
Installation & Fitment:
The DEI Floor and Tunnel Shield II is designed for universal fitment and can be applied to most vehicle models. Its peel-and-stick adhesive backing simplifies installation, allowing you to apply it directly to clean, dry surfaces without the need for drilling, cutting, or special tools. For best results, ensure the aluminum side faces the heat source to maximize reflective properties.
- Fits most automotive models and applications
- Can be trimmed to fit custom shapes and tight spaces
- No cutting, drilling, or special tuning required
- Suitable for use on firewalls, transmission tunnels, floorboards, fuel cells, and exterior under-vehicle areas
What's Included:
- One 21" x 48" sheet of DEI Floor and Tunnel Shield II with adhesive backing
- Installation instructions for optimal application
Ideal For:
- Automotive enthusiasts seeking effective heat management solutions

What does the ETA date mean?
ETA stands for Estimated Time of Arrival. The date shown is calculated using our Available-to-Promise (ATP) system, which tracks real-time supplier commitments to determine when a product is expected to be available for delivery. Specifically, the date is calculated by adding 9 business days from the date a supplier has committed to ship the product, representing a worst-case scenario for when we can expect to receive inventory.
Please note: The ETA is an estimate, not a guarantee. While we work closely with our suppliers to keep dates as accurate as possible, delays due to shipping carriers, weather, customs, or supplier-side issues may occasionally push the actual arrival beyond the date shown. Likewise, inventory may arrive sooner than the ETA in many cases. If you would like to be notified for when this item arrives, sign up for our back in stock notifications!
