## Description

Designed to provide the best possible heat protection in areas where high temperatures are always present and problematic, the Design Engineering Floor & Tunnel Shield II limits heat transfer on fire walls, transmission tunnels, floor boards, fuel cells and other areas where heat is an issue. It provides excellent lightweight thermal protection, acts as a guard against track and road debris, and provides sound deadening as well. Constructed with an embossed 10 mil aluminum face bonded to 1/8" composite glass-fiber core and backed with a high temp super strong pressure sensitive backing, Floor & Tunnel Shield II withstands up to 1750 degrees Fahrenheit of direct continuous heat. The adhesive side holds past 450 degrees Fahrenheit. Its improved multifaceted modern aluminum surface offers improved reflectivity and rigidity and allows for ease of installation. At only 3/16" thick, this product can be shaped and trimmed for a custom fit and is ideal for minimal clearance areas. With a unique and patented finely woven glass-fiber backing, Floor & Tunnel Shield II is the easiest, most cost effective way to control thermal transfer while protecting expensive components and vehicle occupants from extreme heat situations and sound. Floor & Tunnel Shield II can be used on any number of surfaces including, metal, aluminum, carbon fiber, plastic, and more. Multiple uses include: fire walls, under hoods, transmission tunnels, floor pans, fuel cells, and exterior under vehicle locations - anywhere to reflect damaging heat.

Review: quality product - Fantastic product. Easy to form and trim to fit. Without the fiberglass issue like some products. Needed to protect wiring from exhaust heat. Would also work for noise reduction. Made well perfect thickness. very durable. Will be buying again to finish my project. Definitely recommend. Pricey but you get what you pay for.
Review: Excellent heat barrier and VERY GOOD ADHESIVE. - Excellent heat shields. Use them in the engine compartment of my rv. They REALLY stick once they are pressed on. Well made and VERY good adhesive. Good luck if you want to want to remove it.
