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.
