Why are My Double Pane Windows Fogged up in Minnesota?
As windows age, one of the problems that often shows up is moisture between
the panes of glass (sometimes it even shows up as ice in MN). The space
between the 2 panes of glass in your thermopane window should be free of
moisture and completely clear. When the seal fails, moisture enters the space
between the panes and the window “fogs up” (or “ices up”).
The window then becomes less energy efficient and unsightly. It may be time for
new windows. Many beautiful, energy efficient windows are available and
will make your home more comfortable to live in.
