Why Are Your Windows Foggy


In recent years, double-glazed windows have become very popular. A double-glazed window is one that is made with two panes of glass. These panes of glass are kept airtight in the frame. They are separated by a cushion of air. The cushion of air helps to prevent the flow of heat from outside to inside or vice versa; however, your windows might not maintain their airtight seal. If the airtight seal is compromised, you will start to see fog in your windows.

Foggy Windows

Double-glazed windows that no longer have a tight seal will begin to allow outside air between the panes of glass. Canterbury glaziers can repair or replace your double-glazed windows.

  • When outside air is allowed to get between the panes of glass, most of it will still be trapped. That will cause the temperature and humidity between the panes of glass to change.
  • When the temperature and humidity change, they will form condensation that makes your windows foggy.
  • Foggy windows are a sign that they are not sealing properly.

Improper Sealing

If the double-glazed windows are not sealed properly, then you need to make sure that they are repaired as quickly as possible. When they are not sealed properly, they are not insulating your windows properly. The windows are designed to prevent the flow of heat from inside to outside and vice versa. This means that if they are allowing air to pass and condensation to form, they will not be preventing the flow of heat. A good glazier can fix this for you or replace windows that can’t be fixed.
