## Overview

Second Skin Thermal Block is a 1/8-inch thick, peel-and-stick automotive heat shield sheet measuring 12” x 24”, designed to reflect up to 98% of radiant heat. Made in the USA with durable aluminum foil and PET fiber core, it withstands continuous temperatures up to 800°F, resists water, oil, solvents, and flame, and installs easily without tools. Ideal for protecting firewalls, exhaust areas, and under-hood zones, it reduces heat transfer by 100–200°F, enhancing vehicle comfort and component longevity.

## Description

The Thermal Block is a professional-grade automotive heat shield engineered to control extreme engine and exhaust temperatures in vehicles. Designed as a radiant heat barrier, it reflects up to 98% of radiant heat away from critical surfaces when installed with the reflective foil facing the heat source, helping protect vehicle interiors and sensitive components. Excessive engine and exhaust heat can transfer through firewalls, floor pans, and transmission tunnels, causing uncomfortable cabins and long-term damage to wiring, paint, and surrounding materials. Thermal Block provides an effective heat barrier automotive solution by redirecting radiant heat away from these hot zones, reducing heat intrusion, and improving overall driving comfort. Available in multiple pack options, each heat shield mat measures 12” x 24” (2 sq ft) and is 1/8” thick, featuring a reflective aluminum foil surface bonded to a durable PET fiber insulation core. Thermal Block is available in both flat and ridged foil formats to suit different handling and installation preferences. This advanced heat shield material withstands continuous temperatures up to 800°F while remaining flexible and easy to handle. The material resists water, oil, solvents, coolant, and flame, making it suitable for demanding under-hood shielding and underbody environments. Installation is fast and simple thanks to the peel-and-stick heat shield backing. Cut the sheet to size, clean the surface, peel the liner, and apply. The comfortable design allows installation on firewall heat shields, under hoods, floor pans above exhaust pipes, transmission tunnels, mufflers, catalytic converters, fuel tanks, and brake lines. For best results, always face the foil side toward the heat source and maintain a minimum 2-inch air gap. Proudly made in the USA, Thermal Block delivers reliable, OEM-grade car heat protection and automotive thermal protection for restoration projects, performance builds, and everyday vehicles.

Review: This product is unbelievable! - Item as described, honest seller, highly recommend,A+, fast shipping, great value, purchased for my wheeler, installed on my plastic covers and fuel tank to protect from heat from muffler and exhaust pipes. This stuff sticks and protects great. I have since purchased more and use it for many things. Check it out, you will be amazed!
Review: Works great - Applied to the bottom of motorcycle saddlebags. Was concerned about adhesive being strong enough to stick and hold to the material but it seems to be good so far. Blocks the heat well, just hope it last a very long time. I will recommend this to others

## Questions & Answers

**Q: Do we have to remove the black piece under the hood to install this ?**
A: This material should be used with the silver side facing a heat source. If you send us a picture of what you are trying to install it on, we may be able to answer the question better. There are videos of it being used on hoods on our website in the Video Library. You can also call us for further project assistance.

**Q: Gas furnace interior insulation. Yes?  Or No?**
A: Interior no, all of our materials must be kept 2" away from any heat source.

**Q: I am looking at this to place inside of a metal shed that I have in my back yard. Will it work or do I need to stick it to the outside?**
A: Thermal Block (and all thermal deflectors) are used on the hot sides of projects pointed directly at the heat source. Theya re used on engine side firewalls/hoods, undercarriages above exhausts and drive trains, etc. Sounds like your project needs a thermal insulator, like our Heat Wave Pro sheets for keeping the hot air outside and cool inside.

**Q: If used under the hood, does it really keep the top of the hood cooler so as to protect the paint or is a yute version better??**
A: Yes, this is a heat shield or thermal blocker. So, when used across the hood, it will keep the heat from getting to the hood metal, which in turn will keep the paint job on the paint safe from any high heat issues under the hood. Jute, the material we use in our Heat Wave Pro is a thermal insulator, which means it absorbs the heat to keep it from getting through, not block it. Both are exceptionally good options for hood undercarriage. Jute also offers some sound absorption, unlike heat shields, which just focus on the heat.

Nice quality, forms well. Super sticky too. Had to replace a failing shield above the exhaust system on a f150 raptor. This was the perfect size.
