An exhaust heat shield works much like an exhaust wrap. Both retain thermal energy inside your exhaust system. The construction and installation of an exhaust heat shield is far different compared to an exhaust heat wrap. All of the Armor Series™ exhaust heat shield insulation by Heatshield Products feature our exclusive BioCool™ technology. BioCool™ is a non-caustic, non-flammable insulator made from a bio-soluble silica. It does not cause itching and has limited smoke or smell the first time it is heat-cycled. Capable of withstanding 1,800-degrees Fahrenheit continuous and 2,200-degress Fahrenheit intermittent. Our Armor series exhaust insulation can reduce as much as 70 percent of heat radiating up from the exhaust system.

From the original fiberglass wrap, to the industry’s first lava rock exhaust wrap, to the extreme Inferno header wrap, no one has lead the way like Heatshield Products. In our true pioneering spirit we have introduced our Armor series of exhaust heat shield featuring our exclusive BioCool technology. It takes high temperatures and can be installed in a header warranty friendly way.

Heatshield Products® is a family owned and operated business and has been since 1985. They take great care to give you accurate information and bring you the best heat shields, exhaust wraps, heat protective sleeves and thermal insulation around. Thermal management is all about improving the efficiency and performance of your vehicle, vessel, manufacturing processes, or facility. From bulk heat shield textiles, biological and Eco-friendly insulation products, fabricated jackets, and heat shield barriers, we will not be out performed!
