# DEI Floor and Tunnel Shield II 12in x 21in

Floor & Tunnel Shield II(TM) solves the problem of needing a high heat barrier to block heat from any source intruding into interiors and damaging components and electronics. Use as a barrier to reflect and insulate from any heat source. Designed to provide the best possible heat protection in areas where high temperatures are always present and problematic, Floor & Tunnel Shield II limits heat transfer on fire walls, transmission tunnels, floor boards, fuel cells and other areas where heat is an issue. Floor & Tunnel Shield II provides excellent light weight 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, Floor & Tunnel Shield II withstands up to 1750F. Its improved multifaceted modern aluminum surface offers improved reflection and rigidity and allows for ease of installation - aluminum side must face the heat source. 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. This version of Floor and Tunnel II does not include the adhesive backing the Original Floor and Tunnel Shield II has.
