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.

A double-pane window having a dry atmosphere comprising:
- a first pane of transparent material;
- a second pane of transparent material essentially parallel with the first pane;
- a strip of flexible adhesive material disposed along the periphery of the adjacent sides of the panes of transparent material in sealing engagement with the panes enclosing a sealed area between the panes;
- a dry gas within the sealed area between the panes;
- a plurality of rigid spacers each having a stem portion inserted in the flexible adhesive material and having a head portion larger than the stem portion, which head portion is in contact with both panes of transparent material and maintains the panes of transparent material in spaced apart relationship;
- and framing means along the edges and the periphery of the outer sides of the panes of transparent material for holding the panes stationary relative to one another and in contact with the flexible adhesive material.
