DEI Floor and Tunnel Shield II 21 in x 4 ft High Heat Barrier for Automotive Applications

The DEI Floor and Tunnel Shield II is an advanced thermal barrier designed to provide superior heat protection in demanding automotive environments. Constructed with a 10 mil embossed aluminum face bonded to a high-temperature glass-fiber core, this shield effectively reflects and insulates against radiant heat sources up to 1750°F. Its lightweight and flexible design make it ideal for installation in tight spaces such as firewalls, transmission tunnels, floor pans, and fuel cells, helping to prevent heat transfer to sensitive components and interior areas.

Featuring a peel-and-stick high-temp adhesive backing that withstands temperatures over 450°F, the DEI Floor and Tunnel Shield II offers easy application on a variety of surfaces including metal, fiberglass, plastic, and carbon fiber. Its minimal thickness of only 3/16 inches allows for custom shaping and trimming, ensuring a precise fit around contours and tight clearances. The product also acts as a protective barrier against road debris and provides sound deadening benefits, contributing to a quieter, more comfortable interior environment.

Designed for durability and ease of use, this thermal shield is suitable for exterior and interior applications where high heat is a concern. It’s an effective solution for protecting engine compartments, painted body parts, and other critical areas from radiant and conductive heat. Please note, this product should only be applied to surfaces facing the heat source and not directly on exhaust components. With its modern aluminum surface offering enhanced reflection and rigidity, the DEI Floor and Tunnel Shield II simplifies installation while delivering reliable thermal protection in extreme conditions.
