Design Engineering DEI 50502 Floor & Tunnel Shield II Heat Barrier 21" x 48"

The Design Engineering Floor & Tunnel Shield II is a high-performance thermal barrier designed to protect vehicle interiors, components, and electronics from extreme heat intrusion. This versatile heat shield provides superior thermal protection in areas where high temperatures are constantly present and problematic.

Construction & Performance:

• Embossed 10 mil aluminum face bonded to 1/8" composite glass-fiber core
• High-temperature pressure-sensitive adhesive backing holds past 450°F
• Withstands direct temperatures up to 1,750°F
• Only 3/16" thick for minimal clearance applications
• Measures 21 inches x 48 inches (7 square feet of coverage)

Key Features:

• Blocks heat transfer on firewalls, transmission tunnels, floor pans, and fuel cells
• Reduces unwanted road noise by up to 50 percent for improved sound deadening
• Acts as a protective guard against track and road debris
• Lightweight thermal protection with patented finely woven glass-fiber backing
• Can be easily cut with tin snips and shaped for custom fit
• Aluminum side must face the heat source for optimal performance

Applications: Ideal for firewalls, under hoods, transmission tunnels, floor pans, fuel cells, and exterior under-vehicle locations. Can be applied to metal, aluminum, carbon fiber, plastic, and other surfaces. Do not apply directly to exhaust components.
