In the past, double pane windows comprised two pieces of glass that were separated with an air spacer. They were then filled with air or an insulation gas. In recent years, manufacturers have switched to insulated glass units (IGs) that are much more efficient in energy use and are resistant to seal failure. In a window with a failed IG moisture from the air outside seeps through the gap and condenses inside the glass. This cycle eventually breaks the insulating properties of the IG and leaves an odourless residue on the glass.
