ABSTRACT:
A thermal Shutter Shield (R) device comprised of an outer periphery support frame which supports an outer glass area means and an inner glass area means in a parallel mode, the glass area means are normally called windows, glass sliding doors or glass walls including a glass peripheral frame and a glass panel installed therein, the device is further comprised of a Shutter Shield unit spaced between the glass areas, having one or more sets of horizontal and parallel extending tracks which are vertically spaced a distance at least equal to the height dimension of the glass area units, the tracks extend parallel to the plane of the glass area and beyond at least one side of the side edges of the glass area unit, a laminate insulative Shutter Shield is mounted in the track for movement between positions at the side of the glass area unit and in front thereof to block off the entirety of the glass area, the laminate insulative shield includes a frame movably supported on the track and has an imperforate surface layer and an insulation layer material mounted side by side in the frame, the imperforate surface provides a rigidifying support for the rather fragile insulation material, and a seal structure is provided for effecting a seal around the periphery of the glass panel and between the window unit and the insulative Shutter Shield, the Shutter Shield device including the inner and outer glass areas can be pre-assembled at the factory, installed in the outer periphery device support frame with the thermal shutters installed therebetween, the shutters can be manually traversed by actually reaching between the glass areas and pulling and/or pushing the thermal shutters to an opened or closed mode, or a mechanical manually cranked drive device can be used to traverse the shutters to an opened or closed mode, still further the thermal shutters can be automated by using a motorized method for driving the drive unit which will traverse the shutters to a opened or closed mode, the device being totally pre-assembled at the factory will actually reduce cost at the building site.
