If your double glazed window looks cloudy or foggy and the moisture cannot be wiped away, it may be trapped between the two panes of glass.
How does double glazing work?
Double glazing consists of two panes of glass separated by a sealed space. This space contains dry air or an insulating gas, which helps reduce heat transfer through the window. A spacer and seal around the edges keep moisture out of the space between the panes.
What causes the foggy appearance?
Fogging between the panes usually means the seal around the double glazed unit has failed. Once the seal is no longer airtight, moisture can enter the space between the panes.
As the temperature changes, this moisture condenses on the glass. It may initially appear as light misting during colder weather, but the window can become increasingly cloudy over time.
Seals can deteriorate through natural ageing, repeated temperature changes, movement within the window frame, prolonged exposure to moisture or installation issues.
Can foggy double glazing be repaired?
The most reliable solution is usually to replace the failed double glazing glass unit. In many cases, the existing window frame can remain in place if it is still in good condition.
