<p>A system for filling double-glazed panels such as large windows and double layered greenhouse walls with preferably granular material for insulation, shading and/or privacy. This system is characterized by filling the interspace without blowing the conveying gas in the latter thereby avoiding the occurrence of damaging gas pressure in the interspace and allowing the use of relatively thinner glazing sheets of glass, plastic, or the like. This system also allows to sequentially and/or selectively fill any number of panel sections connected to the bottom side of a common header which fills the pane} panel by settling of the granular material therein and in the panel sections through apertures in the bottom of the header. The panel sections are sequentially and/or selectively evacuated by an evacuation duct underlying the lower edge portion of the panel sections.</p> |
