The highest quality reflective heat shield on the market. There is no better way to shield radiant heat away. We use a 1/4" thick ceramic inner pad sandwiched between heavy duty foil and bound together with a stainless steel mesh at the edges. By binding the edges with a stainless steel mesh, we create greater flexibility and a more rugged product. This heat shield withstands 1000°F continuous radiant heat and 400°F of direct contact. As with any aluminum insulation product, it is not designed for direct contact with exhaust systems. this heat shield is intended for wrapping around electrical boxes, air conditioning components, or used as a catalytic converter and muffler heat shield. All of these reflective heat shields may be fastened with Thermal-Tie, safety wire, screws, or rivets. Custom sizes are available.
