ABSTRACT:
An insulating window shade assembly includes a shade frame having a pair of vertical side channels open in a direction facing one another and designed to be mounted on the inside of the window to be insulated. A flexible insulating shade having inner and outer spaced apart parallel panels extends downwardly from the top of the channels, and the margins of the panels extend into the channels. Edge seals are provided in each channel made up of a pair of flexible polyester film strips with the adjacent sides of the strips being spring biased towards one another but being separable so that the margins of the shade panels may lie between them. The flexible character of the strips forms an effective insulating seal about the margins. A rerailer assembly is provided at the tops of the edge seals to guide the margins of the each panel between the strips of the edge seal should they become dislodged.
