ABSTRACT:
The invention comprises a double glazing construction having foldable insulating louvers attached to and located between the glazing panels. The louvers include internal insulating means and dual hingeing means permitting the louvers to be closed and opened as one of the glazing panels is moved relative to the other. The specific configuration of the louvers and the means for attaching the louvers to the glazing permit the louvers, the hingeing means and the glazing to be manufactured from extruded plastic components. The louvers may be coated with a heat and light reflective material to further improve the insulating effectiveness when the louvers are closed and to direct sunlight deeper within a building interior when the louvers are opened.
