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.

A window insulation system for selectively covering and insulating a window having a window pane, said window having a pane supporting structure including an upper cross member, a lower cross member and a pair of upright members, said pane and pane supporting structure covering the opening in the wall bounding the supporting structure, said window insulation system comprising: a valance carried by said pane supporting structure and having a pivotal portion which is pivotally mounted with respect to said pane supporting structure; a shade rod supported at its opposite ends by said pane supporting structure; and an insulated shade mounted on said shade rod, the width of said shade being such that its marginal edges overlap a portion of the upright window pane supporting structure when the shade is drawn, wherein said insulating shade includes an insulating material sheet sandwiched between front and back cover sheets and wherein the insulating material sheet is of a length less than the length of the cover sheets such that one edge of the insulating material is spaced from one edge of said shade secured to said shade rod by a preselected distance to reduce the effective diameter of said shade when rolled upon said shade rod.
