What your double pane windows are up against in New Orleans

The typical IGU uses a spacer to hold two panes apart, a perimeter seal, and sometimes an argon fill to slow heat transfer.

When that seal is intact, the cavity stays dry and clear, and low-E coatings do their job to cut solar heat.

In New Orleans, the edge seal works harder than in many markets due to high ambient humidity, big temperature swings between cooled interiors and 95-degree air, and occasional negative pressure during tropical storms.

Fogging vs normal sweat: how to tell the difference
