Thermo-Tec: The Original in Automotive Heat & Sound Management
Since 1987, Thermo-Tec has been proud to offer customers the latest in exhaust insulating and heat protection technology. Headquartered in Greenwich, Ohio, the brand was built on a single focused mission: conquering the destructive nature of radiant heat in performance and everyday vehicles alike. Decades later, that focus has made Thermo-Tec a household name among builders, racers, and wrenchers worldwide.
A Legacy Built on Innovation
Thermo-Tec is the original manufacturer of high-performance exhaust insulating and heat control products. Since 1987, the company has offered the latest in heat protection technology and has continued to raise the bar for effective, quality heat control products. Through extensive research and new innovations, Thermo-Tec now offers over 130 products that enhance performance by reflecting or dissipating heat. Each product goes through a rigorous testing program to ensure it meets the brand's exacting quality standards before it ever reaches a customer.
In most cases, Thermo-Tec's products are easy to install. In all cases, their products are recyclable, environmentally friendly, and made in the USA. That combination of performance-driven engineering and responsible manufacturing is a core part of what sets the brand apart.
Who Uses Thermo-Tec?
Thermo-Tec products are used to gain an edge in every form of motorsports, including NASCAR, NHRA, IHRA, oval track, and off-road racing. They're also utilized by the military, OEM industrial, aircraft, and marine sectors. Whether you're building a weekend track car, restoring a classic, or simply protecting your daily driver's underhood components, Thermo-Tec has a heat management solution for the job.
The Full Spectrum of Heat Control
Thermo-Tec's catalog covers virtually every heat-related challenge a vehicle can present. Their exhaust heat shields clamp directly onto pipes and mufflers to prevent radiated heat from damaging nearby components. Exhaust system wrap is a go-to solution for reducing underhood temperatures and keeping exhaust gases moving efficiently. For the header and manifold area specifically, exhaust manifold heat shields — including their well-known header manifold blankets — provide a snug, targeted barrier exactly where heat buildup is most intense.
Beyond wraps and shields, Thermo-Tec offers heat reflective tape for sealing, bonding, and securing insulation materials, ensuring a complete and durable installation. Rounding out the lineup, thermal acoustic insulation products address both heat and noise simultaneously — engineered to block out unwanted noise and insulate against extreme temperatures, offering a quieter, more enjoyable ride while also protecting a vehicle's interior from heat.
Why Enthusiasts Trust Thermo-Tec
Extreme heat conditions and the destructive nature of radiant heat continue to be a major problem for vehicle owners. Thermo-Tec products provide logical, easy-to-use solutions that don't require specialized tools or professional installation. From a first-time DIYer wrapping their headers to a professional race team managing underhood temperatures on a competition engine, the brand's depth of product options makes it a trusted resource across all skill levels.
