Design Engineering Floor & Tunnel Shield II 21" x 24" Adhesive Heat and Sound Insulation (3.5 sq. ft.)

Designed to provide the best possible heat protection in areas where high temperatures are always present and problematic, the DEI 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.

• Design Engineering Floor & Tunnel Shield is a premium adhesive-backed insulation designed to reduce heat transfer and dampen noise in vehicle floors and tunnels, improving overall cabin comfort and protecting interior components from heat damage.
• Constructed with a durable aluminum outer layer bonded to a dense sound-deadening core, this shield effectively blocks radiant heat and reduces vibrations from road and engine noise for a quieter driving experience.
• The strong adhesive backing ensures easy, secure installation on metal, plastic, fiberglass, and various other surfaces, conforming well to contours, bends, and tight spaces without cracking or peeling.
• Ideal for automotive restoration, racing, or everyday use, this insulation enhances thermal management by lowering cabin temperatures and reducing driver fatigue caused by heat and noise intrusion.
• Available in multiple sizes, the Floor & Tunnel Shield offers a cost-effective solution for targeted heat and sound insulation, providing professional-grade performance and durability for all vehicle types.
