ABSTRACT:
An insulated glass window assembly including a cordless integral shade with level correction, a sliding follower, and an air permeable spacer assembly. Cords are eliminated by confining the window covering movement to one dimension. Level correction is achieved by pivotally connecting the shade bar to the supporting operator or shade support, so that the bar can be re-leveled by raising or lowering the bar against the IG spacer. The follower slides in a track on one side of the IG. The spacer includes an air passageway between the desiccant chamber and the space between IG space, and the hole is covered by an air-permeable patch to prevent unwanted leakage of desiccant into the viewable area.
