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.
