Double Pane Windows Fogging On Outside

The reason water condenses on the outside surface of the glass is the temperature of the glass drops below the external dew point temperature.

The new double or triple glazing units tend to have inner panes made up of low emissivity glass and this prevents the movement of heat across the glazing unit so the outer pane never gets warm.
