DEI Floor & Tunnel Shield II (Non-Adhesive) - 42in x 48in

DEI is known for making parts that help manage heat in vehicles, and their Floor & Tunnel Shield II is a prime example of that expertise. If you're working on a custom build, restoring a classic, or just trying to keep the cabin cooler in a hot rod, this shield is designed to block unwanted heat from reaching your interior or sensitive components. It works by reflecting and insulating against heat sources, making a big difference in comfort and protecting electronics.

This version of the shield is constructed with a 10-mil embossed aluminum face bonded to a 1/8-inch composite glass-fiber core, giving it a total thickness of just 3/16 of an inch. This slim profile means it can fit into tight spaces where other heat barriers won't. The aluminum side is what you'll want facing the heat source to get the best reflection, and the unique glass-fiber backing not only adds to the insulation but also helps with sound deadening. It's built to handle temperatures up to 1750°F, so it's ready for serious heat, but remember it's not meant to be applied directly to exhaust components. Because this is the non-adhesive version, you'll need to secure it using mechanical fasteners like rivets or screws, which are sold separately.

This sheet measures 42 inches by 48 inches, giving you a good amount of material to work with for firewalls, transmission tunnels, floor pans, or fuel cells. You can easily trim and shape it to fit the contours of your specific application, making it a versatile solution for controlling thermal transfer and reducing noise.
