## 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 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.
Review: Worth the money if you need the protection - This practically holds itself in place. seems to work great.

### ⭐⭐⭐⭐⭐ 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.

### ⭐⭐⭐⭐⭐ Worth the money if you need the protection

This practically holds itself in place. seems to work great.

### ⭐⭐⭐⭐⭐ Good initial quality
*by Z***R on April 18, 2014*

I will re-edit this when I've put some heat to it and seen the miles it holds up to. As far as the product itself though, initial impressions are very good. I had the engine and transmission out of my miata so I could hopefully do this job the right way. There is a video out there of a gentleman putting one of these in with it installed and I can't imagine it would hold up as well. Reasons are numerous but I think the most important being there's no way you could get the tunnel clean enough for proper adhesion. Yes this product is extremely sticky, but like anything adhesive once you clog that surface up with contaminants it's going to lift off the surface and not provide the kind of bond intended. If you've come here, your car is too hot due to tunnel heat most likely. Though I suppose this product would work for lots of places. The aluminum side of this shield resembles the sort of thing I've seen on lots of new oem shields. It's got a cratered surface, it's somewhat reflective in nature. It is fairly stiff as a result, though it bends fairly easily. My application is for a race car (miata) and I've always found the tunnel gets just too hot from exhaust especially during the summer months (I usually don't have carpet either). So hopefully this helps this season. I've attached an image that shows how mine went in. I made sure to thoroughly clean the surface before-hand and started with the driver's side. Working it down and peeling back the adhesive protection layer of the product I was able to get it to finally adhere the way I wanted. Note, I cut my product with tin snips at the folds of the body to help ensure I didn't have any bubbles in where it applied. I don't believe there is any real way to not do this at least on a miata's tunnel. We'll see how well it works but I'm real hopeful it solves or at least helps to mitigate the heat issue. Hoping cutting it the way I did doesn't somehow ruin it's overall effectiveness or make it less long-lived. Will update with how it holds up. [...]
