ABSTRACT:
An improved insulating shade device is provided for increasing thermal resistance and minimizing convective drafts at windows. The device includes a multiplicity of insulating members proportioned for covering a section of the window pane. The insulating members in one embodiment are joined by a suitable cover such that abutting edges of adjacent insulating members pivot with respect to each other. The device is mounted by attaching a support unit to the lintel or upper portion of the window frame. This support unit carries the shade and, in this connection, the upper end portion of the shade is joined with the support unit. Means are provided for drawing the shade to its folded position such that it is stored in a compact manner below the support unit.
