This universal, flexible heat shield is rugged enough to be used for almost any radiant heat application. If used with a 1-inch air gap between the heat source and Thermaflect Shield, and good air flow and this heat shield can reflect over 90% of radiant heat. We use a 1/4-inch thick version of our BioCool inner pad sandwiched between heavy duty foil and bound and sewn together with a stainless steel mesh at the edges. By binding the edges with this mesh, we create greater flexibility and a more rugged product. This heat shield withstands 1100-degrees Fahrenheit continuous radiant heat and 500-degrees Fahrenheit of direct contact. Thermaflect Shield is intended for wrapping around air boxes, electrical boxes, air conditioning components, or used to shield radiant heat shield from catalytic converter, muffler, DPF, on the bottom of the floor pan. Thermaflect Shield may be fastened with Thermal-Tie, safety wire, screws, or rivets. This heat shield is not recommended for direct contact with heat source, such as an exhaust system, it is used to deflect heat away.
