ᐅ Moisture has formed between the window panes.

Hello,

Today, after a night with temperatures around minus 3 degrees Celsius (27°F), we noticed condensation between the window panes.

The window installer said this is not a defect. However, he wasn’t able to explain why it happens...

What are your thoughts?

Thank you.

Formed – well, I would say that humidity condensed into droplets.

He should be able to if he claims it’s not a defect. I suspect a tiny leak in the seal of the insulated glass unit. Then the gas inside exchanges with the outside air and all its components. I don’t see this resolving itself on its own.

I agree with what 11ant said:

An inert gas is filled between the panes for insulation. If this gas is not properly sealed in, it can mix with more humid outside air. This then condenses on the glass at low temperatures.

We experienced this several times in our rental apartment. Compared to the windows without moisture inside, those affected were noticeably colder during the colder months.

This was reported to the landlord as a defect and the windows were replaced each time...
