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.

The invention claimed is: 1. A heat shield for conduit comprising: a flexible, single, continuous shield body sheet consisting of a conduit-facing interior layer and an exterior layer adjacent the interior layer, the sheet having first and second ends and first and second side edges and being capable of adapting to various conduit cross-sectional shapes and sizes and directional changes of the conduit longitudinal axis and not substantially adhering to the conduit, and the exterior layer being reflective; and a means for coupling the side edges of the shield body to each other about the conduit such that a substantially longitudinal gap exists between the first side edge and the second side edge or the shield body sheet, such that the shield body is attached to the conduit without removal of the conduit from its installation. 2. A heat shield as stated in claim 1, further comprising a shield flap extending from a shield body side edge and capable of extending into a gap between first and second side edges. 3. A heat shield as stated in claim 1, wherein the interior layer has a conductive coating. 4. A heat shield as stated in claim 1, wherein the body sheet further comprises an accessible, insulation-receiving pocket capable of receiving insulating or heat dissipating material. 5. A heat shield as stated in claim 1, wherein the interior layer is woven silica. 6. A heat shield as stated in claim 5, wherein the exterior layer is a polyester film having a reflective aluminum finish. 7. A heat shield as stated in claim 6, wherein the coupling means includes at least one lace and at least one pair of eyelets, one eyelet located along the first side edge and the other located substantially opposite the other along the second side edge. 8. A heat shield as stated in claim 6, wherein the shield body sheet circumscribes the conduit less than one revolution. 9. A heat shield as stated in claim 6, further comprising an air gap between the conduit and the shield body sheet, wherein the gap is between 쩌 inch to 쩐 inch deep and the coupling means is a clamp. 10. A heat shield for conduit comprising: a flexible, single, continuous shield body sheet consisting of a conduit-facing interior layer and an exposed exterior layer adjacent the interior layer, the sheet having first and second ends and first and second side edges and being capable of adapting to various conduit cross-sectional shapes and sizes and directional changes of the conduit longitudinal axis and not substantially adhering to the conduit, and the exterior layer being reflective; and a plurality of conduit-mounting clamps, each clamp passing through a pair of apertures and a portion of each clamp being adjacent a portion of the interior surface of the body sheet. 11. A heat shield as stated in claim 10, further comprising a shield flap extending from a shield body side edge and capable of extending into a gap between first and second side edges. 12. A heat shield as stated in claim 10, wherein the body sheet further comprises an accessible, insulation-receiving pocket capable of receiving insulating or heat dissipating material. 13. A heat shield as stated in claim 10, further comprising an air gap between the conduit and the shield body sheet, the gap being between 쩌 inch to 쩐 inch deep. 14. A flexible, single, continuous shield body sheet consisting of a conduit-facing interior layer and an exterior layer adjacent the interior layer, the sheet having first and second ends and first and second side edges and being capable of adapting to various conduit cross-sectional shapes and sizes and directional changes of the conduit longitudinal axis and not substantially adhering to the conduit, and the exterior layer being reflective; and a plurality of conduit-mounting clamps capable of operably securing the body sheet to a conduit, where each clamp passes through a pair of apertures and a portion of the clamp is adjacent both a portion of the body sheet and the conduit. 15. A heat shield as stated in claim 14, wherein the body sheet further comprises an accessible, insulation-receiving pocket capable of receiving insulating or heat dissipating material. 16. A heat shield as stated in claim 14, further comprising an air gap between the conduit and the shield body sheet, the gap being between 쩌 inch to 쩐 inch deep. 17. A method of protecting a conduit from a heat source comprising the steps of: wrapping a portion of a conduit with a flexible, single, continuous sheet so that the sheet is placed between the conduit and a heat source, the sheet consisting of a conduit-facing interior layer and an exterior layer adjacent the interior layer, the sheet having first and second ends and first and second side edges and being capable of adapting to various conduit cross-sectional shapes and sizes and directional changes of the conduit longitudinal axis; and securing the sheet to the conduit via a plurality of clamps, where each clamp passes through a pair of apertures in the sheet and a portion of the clamp is adjacent both a portion of the body sheet and the conduit. 18. A method of protecting a conduit as stated in claim 17, further comprising the step of placing insulating or heat dissipating material within an accessible, insulation-receiving pocket of the sheet. 19. A method of protecting a conduit as stated in claim 17, wherein the step of securing provides an air gap between the conduit and the shield body sheet, the gap being between 쩌 inch to 쩐 inch deep. 20. A method of protecting a conduit as stated in claim 17, wherein the conduit is an automotive exhaust pipe.
