Second Skin Thermal Block Automotive Heat Shield - 1 Sheet 12” x 24” — Open-Box, 6% Off

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.

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.
