Condensation between the panes of a double-glazed or insulated window or door often indicates an issue with the seal that separates the two glass panes. Continue reading to find out why this happens and how to address it.
Windows and doors either have a sealant or rubber that keeps the airspace between the panes dry and prevents moisture from getting in. When the seal fails, moisture from outside air enters the space between the panes. Finally, when temperatures drop, the moisture condenses and leads to foggy or cloudy windows. There are several reasons why the seal of a window may fail.
1. Poor Manufacturing/Installation
Substandard materials, shoddy development, or poor installation can lead to a much shorter lifespan of your windows. Even reputable manufacturers may sometimes produce a batch of windows with a defect.
Suggestion: Be sure to check if your windows are under warranty before you schedule any repairs. You may be entitled to a replacement, so don't risk voiding that warranty.
2. Age/Natural Wear and Tear
The seals of windows and doors under heavy use naturally leads to faster wear and tear. After the seals are worn out, they can no longer keep air and moisture from slipping inbetween panes. The same comes with age, the seals on older windows often degrade faster than the glass panes.
Suggestion: Frequent and proper maintenance will prolong the lifespan of your windows. Such things as frequent cleaning and wiping the frames will prevent the build up of grime that will erode the seals of your windows and doors.
Additionally, practice general care not to physically damage the window and door seals when performing routine activies (opening and closing, cleaning, moving furniture in and out of the home, etc).
3. Temperature Changes
Frequent and significant changes in temperature can severely impact window and door seals. For example, extreme cold can cause the sealant to contract, while extreme heat can cause it to expand. These temperature fluctuations can cause seals to crack or become less efficient in maintaining their barrier against moisture.
If you notice condensation or fogging between the panes of your windows or doors, check if they are still under warranty and consult a professional to ascertain the condition of the seal and determine the best course of action for repair or replacement.
