Fits Most Models
50501
Overview:
The DEI Floor and Tunnel Shield II is a high-performance thermal barrier designed to reflect and insulate against extreme heat sources in your vehicle. Ideal for areas where heat buildup is a concern—such as firewalls, transmission tunnels, floorboards, and fuel cells—this shield helps protect critical components and vehicle occupants from damaging temperatures.
Whether you are a daily driver, a track enthusiast, or someone who frequently encounters high-heat environments, this lightweight and durable shield offers reliable thermal protection while also reducing noise and guarding against road debris. Its adhesive-backed design ensures a secure, long-lasting installation for a comfortable interior at any temperature.
Key Features:
The Floor and Tunnel Shield II combines advanced materials and thoughtful engineering to deliver superior heat management and sound deadening benefits:
- Embossed 10 mil dimpled aluminum face for enhanced heat reflection and rigidity
- 1/8" composite glass-fiber core provides excellent thermal insulation and durability
- High-temperature pressure-sensitive adhesive backing holds securely up to 450°F for a reliable "do-it-once" installation
- Withstands temperatures up to 1750°F on the aluminum face, making it suitable for extreme heat zones
- Only 3/16" thick, allowing for easy shaping and trimming to fit tight or minimal clearance areas
- Multifaceted aluminum surface improves reflection and simplifies installation—aluminum side must face the heat source
- Patented finely woven glass-fiber backing enhances strength and sound deadening properties
- Protects engine compartments, painted body parts, and other sensitive areas from heat damage
- Acts as a guard against track and road debris while providing sound insulation
- Suitable for use on a variety of surfaces including metal, aluminum, carbon fiber, and plastic
Construction & Design:
The Floor and Tunnel Shield II features a robust construction combining a 10 mil embossed aluminum face bonded to a 1/8" composite glass-fiber core. This layered design provides a lightweight yet highly effective thermal barrier. The aluminum surface is engineered to reflect radiant heat efficiently, while the composite core insulates against conductive heat transfer.
The shield’s adhesive backing is formulated to withstand high temperatures, ensuring a secure bond that resists peeling or failure even in demanding environments. Its thin 3/16" profile allows for installation in tight spaces without compromising fitment or clearance.
Installation & Fitment:
This adhesive-backed sheet is designed for straightforward installation on most vehicle models. Simply peel and stick the shield with the aluminum side facing the heat source to maximize heat reflection. The product can be easily cut and shaped to fit custom areas such as firewalls, transmission tunnels, floor pans, and fuel cells.
No cutting, drilling, or special tuning is required, making it an efficient and cost-effective solution for heat management in a wide range of automotive applications.
- Peel-and-stick application for quick and secure mounting
- Customizable size and shape for precise fitment
- Compatible with metal, aluminum, carbon fiber, plastic, and other surfaces
Ideal For:
- Protecting engine bays and transmission tunnels from excessive heat
- Reducing heat transfer on firewalls and floorboards
- Shielding fuel cells and exterior under-vehicle components
- Enhancing occupant comfort by lowering interior temperatures
- Providing sound deadening and debris protection in high-heat environments
