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 1750°F.
