The invention provides methods of producing and servicing insulating glass units. Methods are provided for reducing the pressure differential on an IG unit, for changing the interior pressure within an IG unit, and for changing the gaseous interior composition within an IG. These methods can be practiced by forming a hole through at least one of the panes of an IG unit, and flowing gas through the hole. One method includes forming a hole through one of the panes of an IG unit, flowing gas through the hole, and sealing the hole with an optically clear sealant (e.g., a transparent resin). A number of methods for producing IG units are also provided. Further, several kits are provided for servicing IG units. There is also provided a method for detecting leaks in an IG unit by flowing an opaque gas into the unit and observing the unit to detect leaks of the opaque gas therefrom.
A method of servicing an insulating glass unit, wherein the insulating glass unit includes a pair of spaced-apart panes and a spacer joining peripheral confronting inner surfaces of the panes, the spacer and the confronting inner surfaces of the panes together defining a between-pane space containing a gaseous interior composition at an interior pressure that is different than the ambient exterior pressure outside the panes, such that a pressure differential exists between the interior pressure and the exterior pressure, the method comprising:
A method of servicing an insulating glass unit, wherein the insulating glass unit includes a pair of spaced-apart panes and a spacer joining peripheral confronting inner surfaces of the panes, the spacer and the confronting inner surfaces of the panes together defining a between-pane space containing a first gaseous interior composition, the method comprising:
A method of servicing an insulating glass unit, wherein the insulating glass unit includes a pair of spaced-apart panes and a spacer joining peripheral confronting inner surfaces of the panes, the spacer and the confronting inner surfaces of the panes together defining a between-pane space having a first gaseous interior pressure, the method comprising:
A method of servicing an insulating glass unit, wherein the insulating glass unit includes a pair of spaced-apart panes and a spacer joining peripheral confronting inner surfaces of the panes, the spacer and the confronting inner surfaces of the panes together defining a between-pane space, the method comprising:
A method of servicing an insulating glass unit, wherein the insulating glass unit includes a pair of spaced-apart panes and a spacer joining peripheral confronting inner surfaces of the panes, the spacer and the confronting inner surfaces of the panes together defining a between-pane space, at least one of the panes of the insulating glass unit having a hole formed therethrough, the method comprising sealing said hole by flowing sealant into said hole, wherein the sealant flowed into said hole is a substantially transparent resin, and wherein said resin is flowed into said hole while maintaining the resin at room temperature.
A method of servicing an insulating glass unit, wherein the insulating glass unit includes a pair of spaced-apart panes and a spacer joining peripheral confronting inner surfaces of the panes, the spacer and the confronting inner surfaces of the panes together defining a between-pane space, the method comprising:
