Abstract
A split sleeve for insulation of heat generating components, such as an exhaust gas recirculation device, comprises an outer layer of knitted woven or braided glass fiber yarn. A first metal wire skeleton or frame in the form of a continuous wire support for the outer layer is bent in a first step with a series of reverse bends to form a comb-like structure and in a second step to a C-shaped cross-sectional configuration in which the wire defines a cavity and the wire bends define an opening extending lengthwise of the cavity. A layer of heat insulating mineral paper is spaced from the cover layer by the metal wire skeleton. The heat insulating mineral paper is provided with a metal foil layer on the side away from the metal wire skeleton. A second metal wire layer configured like the first extends lengthwise of the sleeve and spaces the reflective surface of the foil from the heat generating component. The various layers of the sleeve are secured together to form an axially extending opening which fits over the component requiring insulation.
