<p>A multi-paned insulated light, such as a window, incorporates an interior panel spacer/seal that includes a thermal insulating layer of cardboard. The cardboard serves as a low cost insulating layer and may be used in conjunction with rolled or extruded metal spacer forms, so as to vastly diminish the thermal bridging effect normally present with such metallic sections. The cardboard spacer can be used adjoining either the "cold" pane or the "hot" pane of the multi-paned unit, or may be interposed between adjacent metallic sections, as a thermal break therebetween. The cardboard is preferably sealed with a surface sealing layer such as polyvinyl alcohol, to effectively preclude gas percolation therepast. Alternatively, an effective gas seal such as polyvinyl alcohol may be incorporated into the cardboard at its time of manufacture. <IMAGE></p> |
