DEI Floor and Tunnel Shield II DEI50501 High-Temperature Heat Barrier

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 annd 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 in. composite glass-fiber core and backed with a high temp super strong pressure sensitive backing, Floor and Tunnel Shield II withstands up to 1750F. The adhesive side holds past 450F. 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 in. 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 and 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 and Tunnel Shield II can be used on any number of surfaces including, metal, aluminum, carbon fiber, plastic, and more. 10 mil dimpled aluminum face Protection for engine compartments Protection for painted body parts Comfortable interior at any temperature Hi-temp adhesive for a do-it-once install Extreme heat barrier - aluminum side should face the heat Only 3/16 in. thick Use as barrier to reflect and insulate from any heat source Great for exterior applications DO NOT apply directly to exhaust components.

The DEI Floor and Tunnel Shield II is a lightweight, self-adhesive heat barrier designed to reflect and insulate against extreme radiant heat in automotive applications. Part number DEI50501 helps protect vehicle interiors, electronics, painted body panels, fuel cells, and other components from heat intrusion while also reducing unwanted road, tire, and engine noise. Its versatile construction is suitable for firewalls, transmission tunnels, floor pans, under-vehicle areas, oil tank boxes, and other locations where heat control is essential.

Constructed with an embossed 10 mil aluminum face bonded to a composite glass-fiber core, the shield withstands direct temperatures up to 1,750 degrees F. The aggressive pressure-sensitive adhesive backing remains effective beyond 450 degrees F for a durable, do-it-once installation. The aluminum surface must face the heat source to provide proper radiant heat reflection. The material can be trimmed and formed around contours, making it well suited for tight-clearance areas and custom installations on metal, aluminum, carbon fiber, plastic, fiberglass, and other compatible surfaces.

DEI Floor and Tunnel Shield II provides thermal protection, sound deadening, and resistance against track and road debris in a single flexible barrier. Installation is straightforward: measure, trim, peel, and stick the shield into place using a clean, properly prepared surface. For safe and effective use, do not apply the product directly to exhaust components. This product is intended for universal automotive applications where additional protection from radiant heat is required.
