Product description
EXTREME RADIANT HEAT PROTECTION: Thermal Block is a 1/8″ thick automotive heat shield and radiant heat barrier designed to reflect up to 98% of radiant heat. Available in multiple pack options, each sheet measuring 12” x 24” (2 sq ft). It is ideal for reducing engine and exhaust heat transfer through firewall heat shield, floor pans, and under-hood insulation areas to keep interiors cooler.
RATED FOR EXTREME TEMPERATURES: Built to withstand continuous exposure up to 800°F (427°C), this aluminum heat shield performs reliably near engines, exhaust pipes, mufflers, and catalytic converters. Designed as a heat barrier automotive solution that helps reduce surface temperatures by 100–200°F when installed with foil facing the heat source.
OEM-GRADE MATERIALS & DURABILITY: Constructed with a heat-resistant reflective aluminum foil and PET fiber insulating core, this heat shield material resists water, oil, solvents, coolant, and flame. This heat shield mat is engineered for long-term performance in harsh under-hood and underbody automotive environments.
FLEXIBLE & PEEL-AND-STICK INSTALLATION: Lightweight, self-adhesive heat shield design flexibly bends around curves and tight spaces. Cut-to-fit insulation sheet installs easily on clean surfaces with no special tools. Always face the foil side toward the heat source.
VERSATILE AUTOMOTIVE APPLICATIONS: Ideal for engine, firewall, transmission tunnels, turbochargers, hood liners, floor pans, mufflers, fuel tanks, brake lines, and under-hood insulation zones. Requires a minimum 2-inch air gap for optimal performance. Proudly Made in the USA.

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!

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

Solid product but pricey.
I use this on both my WRX track car and my home generators outdoor enclosure. I recommend it but dang is it expensive.. I use it to reduce direct heat and reduce noise.Adhesion is strong, cutting and placing is easy.

Great quality!
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.

Used on a rv generator hot air exhaust diversion
Used this to diver hot exhaust cooling air away from my rv generator and to protect my fiberglass compartment from the heat. Seem to work ok for heat insulation, and so far the adhesive is staying tight on the surfaces it stuck too. Time will tell.

Great for aux fuel tanks!
Purchased to insulate a Rade Garage aux fuel tank on my KTM to prevent fuel boiling. Thick, but not too thick. Molds well. Easy to cut.
