A gas monitor for detecting the presence of absence of a noble gas in the space between two window glazing panels. The monitor is preferably non-reactive with the noble gas, but reactive in a visible way with ambient air. When the noble gas leaks out of the space between the glazing panels and ambient air infiltrates, the monitor provides a visual indicator of the occurrence.

In combination, a window including two or more space glazing panels defining a space therebetween, said glazing panels secured to a window frame so as to seal said space against intrusion of outside air, an inert gas substantially filling the space between said glazing panels, and a gas monitor positioned in said space, said monitor comprising a member which is chemically non-reactive with said inert gas and assumes a first state when positioned in said space, said member chemically reactive with at least major element of outside air wherein leakage of said inert gas and corresponding displacement by said outside air causes said member to virtually immediately assume a second state visibly distinct from said first state whereby leakage of the inert gas from said space is readily detectable.
