@pyrrhula Thanks. This is a double paned window. We took down the storm window so I could take better pictures. That is okay during the mild winters, but I think we made a mistake this winter. In addition, the nearby humidifier really puts a lot of moisture on this window. I think we may have to turn the humidifier knob down a notch or two.
Hpw many glasses have you in you windows? Remeber winters in Sweden they had three .
