DEI Floor and Tunnel Shield II 21in x 48in - High-Temperature Heat Barrier for Automotive Applications

The DEI Floor and Tunnel Shield II provides an effective solution for blocking engine and exhaust heat transfer into vehicle interiors while offering a sleek black finish. Designed with a proprietary high-temperature black coating, this shield effectively controls radiant and convective heat, helping to maintain a cooler cabin environment and protect sensitive components from heat damage. Its versatile design allows for easy shaping and trimming to fit a variety of applications such as firewalls, trans tunnels, floor pans, and oil tank boxes, making it suitable for a broad range of automotive projects. Constructed with an embossed 10 mil aluminum face bonded to a 1/8-inch composite glass-fiber core, the shield combines durability with thermal resistance, withstanding direct temperatures up to 1750°F. The high-strength pressure-sensitive adhesive backing remains effective at temperatures over 450°F, ensuring a secure installation even in high-heat conditions. The shield’s low profile, requiring only 3/16 inches of clearance, facilitates installation in tight spaces without sacrificing performance. Its flexible design allows it to conform to complex contours, ensuring comprehensive coverage and effective heat blocking. The black coating is resistant to wind and water, maintaining its integrity in various environmental conditions. This product is suitable for multiple vehicle components, including firewalls, undercarriages, and floor pans, and helps reduce unwanted road, tire, and engine noise. It is important to avoid applying the shield directly to exhaust components, as sharp bends or bending in a metal break may crack the black coating, although this does not impact its thermal performance. The shield is easy to install—simply trim, peel, and stick—making it an efficient upgrade for any automotive heat management system. Prioritize safety and durability with the DEI Floor and Tunnel Shield II, a reliable barrier designed to enhance vehicle comfort and component longevity without the need for additional complex mounting hardware.
