Abstract: The present invention relates to a heat shield for pipes and tubes that is flexible, has an interior insulating layer, and has an exterior reflective layer. A shield may include a flap extending from the shield body for covering a portion of the component not already covered by the shield body. The interior layer faces the exhaust pipe, is made of woven silica, and may include a conductive coating. The exterior layer is an aluminum finish. The heat shield may be secured with stainless steel clamps or a lace and installed on an installed pipe or tube. The heat shield may be installed with an air gap between the pipe and the heat shield.
