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 and backed with a high temp super strong pressure sensitive backing, Floor & Tunnel Shield II withstands up to 1750 Deg F of direct continuous heat. The adhesive side holds past 450 Deg F. 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.
