ABSTRACT:
A modular, self-contained window insert made up of two panes of glass or impact resistant plastic which are secured within a frame which is sealed to prevent the entry of dust into the interior of the window unit. A shade in the form of a double accordian, collapsible sheet is placed within the window unit between the two panes of glass and can be moved upward or downward by use of a perimeter control mechanism secured to the frame.
