Product Details

What you get with this DEI Floor and Tunnel Shield II kit is one 21-inch by 48-inch sheet, totaling 7 square feet of material. This shield is designed to block heat from entering your vehicle's interior or damaging nearby components. It's especially useful for areas where high temperatures are a constant issue, like firewalls, transmission tunnels, and floor pans. It also helps guard against road debris and cuts down on noise.

This shield is well-built with a 10-mil embossed aluminum face bonded to a 1/8-inch composite glass-fiber core. It’s backed with a strong, high-temperature pressure-sensitive adhesive that holds up to 450°F, and the shield itself can handle direct heat up to 1750°F. The improved aluminum surface offers better reflection and rigidity, making it easier to shape and trim for a custom fit, even in tight spots. It’s only 3/16 of an inch thick, so it fits well in areas with minimal clearance. The aluminum side should always face the heat source.

This shield can stick to a variety of surfaces, including metal, aluminum, carbon fiber, and plastic. It’s a straightforward way to manage heat transfer and protect both your vehicle's components and its occupants from extreme heat and sound.
