Abstract
A double-pane window containing a dry atmosphere is produced by placing two panes of transparent material in a spaced-apart relationship; a sealing means is placed about the periphery of the adjacent faces of the panes of transparent material to enclose a sealed area which is then evacuated and filled with a dry gas. The window is then mounted in a suitable frame to maintain the panes of transparent material in a suitable spaced apart relationship.
