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.
Claims24
A window assembly comprising an exterior glazing pane, an interior glazing pane spaced from said exterior pane and movable relative to said exterior pane, a plurality of louvers positioned between said exterior pane and said interior pane, a plurality of opposed parallel mullions extending from said exterior and interior panes, said mullions being parallel with said louvers, said louvers being longitudinally attached to pairs of said opposed parallel mullions and including longitudinal hinge means to permit the movement of the interior pane relative to the exterior pane.
A louver for use with a window or skylight comprising a generally longitudinal central portion, slideable longitudinal attachment means and hinge means, said hinge means joining said longitudinal attachment means to the central portion, and said slideable attachment means comprising an extruded section adapted for slideable assembly or disassembly with complementary longitudinal attachment mean to form a continuous air tight seal.
A window assembly comprising a glazing pane, a plurality of parallel louvers, each of said louvers having at least one longitudinal hinge extending the length of the louver, a first plurality of mullions parallel to said louvers and extending from said pane, said mullions longitudinally engageable with said louvers, a second plurality of parallel mullions longitudinally engageable with said louvers opposite said first plurality of mullions, said second plurality of mullions including means for affixation to a second glazing pane.
