With a durable 10 mil embossed aluminum face bonded to a 1/8" composite fiberglass core, it withstands continuous heat up to 1750°F and adhesive temperatures beyond 450°F. Its flexible 3/16" thickness allows custom fitting in tight vehicle spaces, making it ideal for automotive restoration, racing, and everyday thermal management. ## Description Designed to provide the best possible heat protection in areas where high temperatures are always present and problematic, the Design Engineering 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. Review: Excellent product. Takes patience to install if you want an excellent result. - This is a very high quality product but there are things you need to know. First, it is not like working with that rubberized sound deadening material that goes under your carpet. This uses a much thicker aluminum foil over a fiberglass material with a very aggressive adhesive. To give the adhesive its best chance, I started by cleaning my 140k mile floor pan multiple times with mineral spirits, prepped it with scotch bright pads and sand paper, then and gave it a fresh rattle can paint job. I let the paint cure for a week before installing the tunnel shield. It took a 42x48 and 21x48 sheet to do the entire tunnel area from frame rail to frame rail of my '04 Miata. Once the adhesive makes anything more than the lightest contact, its difficult to remove without separating the fiberglass layer so get it right the first time. I created a template with paper bags and masking tape. then cut the template in such a way that it would lay flat. I then layed out the template pieces on the tunnel shield material to plan my cuts. I bought an inexpensive pair of scissors (ASIN B00LSWLAA8) and they made it through the job... I needed to stop periodically to clean the adhesive and fiberglass off them. The cut edges are sharp so wear some gloves! I roughly contoured the tunnel shield to my project BEFORE removing the paper backing. I then carefully positioned my work and gradually removed the paper backing while rolling it in. Work slowly and deliberately. The foil is flexible enough to roll into and around contours but it does have its limits. The roller I used: (ASIN B07X5SV5FD), its a good quality product that should last through many projects. You'll need to seal the edges since water could get into the fiberglass layer. DEI recommends their tape for this purpose but several people had negative things to say about the tape. On the recommendation of another enthusiast, I sealed the edges with RTV. I used loctite grey #5699 ASIN B0794BYCZ2. The pressurized container works in any orientation and made it easy to apply a consistent bead. Mask along your seams so you get straight, tidy edges. Again if you work slowly and deliberately, you can get good results. I worked in the silicone with a finger and wore heavy Venom Steel nitrile gloves to keep the chemicals off/out of my body (ASIN B00Y2OFGMW). Good Luck! Review: Excellent heat barrier and VERY GOOD ADHESIVE. - Excellent heat shields. Use them in the engine compartment of my rv. They REALLY stick once they are pressed on. Well made and VERY good adhesive. Good luck if you want to want to remove it. ## Features - Premium Adhesive-Backed Insulation: 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 - Durable Construction with Aluminum Layer: 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 - Strong Adhesive Backing for Easy Installation: 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 - Enhanced Thermal Management: Enhances thermal management for automotive restoration, racing, or everyday use by lowering cabin temperatures and reducing driver fatigue caused by heat and noise intrusion - Multiple Size Options Available: 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 - Extreme Heat Resistance: Withstands up to 1750 degrees Fahrenheit of direct continuous heat with its embossed 10 mil aluminum face bonded to 1/8 inch composite glass-fiber core, while the adhesive backing holds past 450 degrees Fahrenheit - Compact and Flexible Design: At only 3/16 inch thick, this product can be shaped and trimmed for a custom fit, making it suitable for minimal clearance areas and tight spaces in various vehicle applications ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B000CEO5W8 | | Best Sellers Rank | #43,530 in Automotive ( See Top 100 in Automotive ) #76 in Automobile Insulation | | Brand | Design Engineering | | Brand Name | Design Engineering | | Coverage | 14 square feet | | Customer Reviews | 4.8 out of 5 stars 436 Reviews | | Global Trade Identification Number | 00607078505033 | | Included Components | Design Engineering 50503 | | Item Dimensions L x W | 48"L x 6"W | | Item Thickness | 0.19 inches | | Item Type Name | AUTO_PART | | Item Weight | 2.49 kg | | Manufacturer | Design Engineering | | Manufacturer Part Number | 50503 | | Manufacturer Warranty Description | Manufacturer Warranty | | Material | Aluminum | | Material Type | Aluminum | | Model Number | 50503 | | Number of Items | 1 | | Number of Packs | 1 | | Part Interchange Info | 050503 | | Product Dimensions | 48"L x 6"W | | Recommended Uses For Product | auto racing | | UPC | 099998581271 607078505033 799916897650 | | Unit Count | 14 Square Feet | ## Product Details - **Brand:** Design Engineering - **Item Thickness:** 1 Inches - **Material:** Aluminum - **Product Dimensions:** 48"L x 6"W - **Recommended Uses For Product:** auto racing ## Images ![Floor & Tunnel Shield II 42" x 48" | Exhaust Heat Shield Cover Reduces Radiant Engine Heat Direct-Fit Corvette/Muffler Part High-Temp Reflective Barrier - Image 1](https://m.media-amazon.com/images/I/71YWQu11VlL.jpg) ## Available Options This product comes in different **Size, Style** options. ## Customer Reviews ### ⭐⭐⭐⭐⭐ Excellent product.
