- applying a first deposit to the inside face of the first pane;
- and
- applying a second deposit to the outside face of the first pane, wherein the first deposit and the second deposit are applied substantially simultaneously.
A method of fabricating a window assembly, comprising the steps of:
- providing an insulating glass unit including a first pane, a second pane, and a spacer interposed between the first pane and the second pane;
- the first pane having an inside face, and an outside face;
- the second pane having an inside face and an outside face;
- the inside face of the first pane, the inside face of the second pane, and a surface of the spacer defining a channel;
- positioning an applicator within the channel;
- biasing the applicator toward the spacer of the insulating glass unit with a preselected force;
