ABSTRACT:
A device for use in combination with a window unit including a window frame and glass panels mounted in the window frame. The device is comprised of a shutter unit having one or more sets of horizontally and parallel extending tracks which are vertically spaced a distance at least equal to the height dimension of the window unit. The tracks extend parallel to the plane of the glass panel and beyond at least one of the side edges of the window unit. A laminate insulative shield is mounted in the track for movement between positions at the side of the window unit and in front thereof to block off the entirety of the glass panel. The laminate insulative shield includes a frame movably supported on the track and has an imperforate surface layer and an insulation material layer mounted side-by-side in the frame. The imperforate surface provides a rigidifying support for the rather fragile insulation material. A seal structure is provided for effecting a seal around the periphery of the glass panel and between the window unit and the insulative shield.
