ABSTRACT:
A heat protective sleeve for the protection of elongated members is disclosed, the sleeve having a first sheet of insulative material with an outer reflective layer. Oppositely disposed edges of the first sheet have means for joining the edges to a portion of the first sheet in overlapping relationship to form a tubular sleeve. A second insulative sheet is attached to the outer surface of the first sheet inward from the edges. The second sheet also has a reflective layer on its outer surface and is attached to the first sheet along its edges, parallel to the edges of the first sheet, thus, forming an air pocket between the sheets. A stiff monofilament wire bent into a spiral or other shape is disposed within the air pocket to maintain the pocket shape. In use, the air pocket is positioned facing a heat source and the sleeve interposes a reflective layer, an insulating layer, an air pocket, a second reflective layer and a second insulating layer between the elongated members and the heat source.
