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.

Abstract: An improved window insulation system is provided which serves to establish a static air panel between the shade and the window pane. The system includes a valance which supports the spring biased shade rod about which the shade is rolled. The valance has a pivoted portion which can be moved away from the shade to facilitate its rolling and to reduce wear on the shade during the rolling operation. When the pivotal portion of the shade is secured in position, it establishes the position of the upper portion of the shade while securing means seal the upright and lower marginal edges of the shade to define the static air panel. To facilitate the rolling operation of the insulated shade, the shade, in one embodiment, includes a plurality of cross seams spaced by preselected distances to increase the shades flexibility.
