Do you see condensation between your panes?
Before planning to replace your entire windows, it is important to know this: in many cases, only the sealed glass unit needs to be replaced.
On Montreal’s South Shore, we regularly receive calls from homeowners who believe they need to replace their entire windows… when the problem actually comes only from the sealed glass unit.
Here’s how to tell the difference.
What is a fogged-up sealed glass unit?
A sealed glass unit consists of two panes of glass hermetically sealed together with an insulating space between them.
Over time, the seal can lose its airtightness.
Result:
- Condensation between the panes
- Persistent condensation
- Cloudy appearance
- Reduced energy efficiency
This phenomenon is common in Quebec, particularly in winter.
Replace the window or just the sealed glass unit?
The question comes up often:
Do you need to replace the entire window?
In most cases:
If the frame is in good condition
If the structure is stable
If the problem is purely visual or related to insulation
It is possible to replace only the sealed glass unit.
This allows you to:
- Keep your existing frame
- Reduce costs
- Avoid major work
- Extend the lifespan of your windows
