we have a fixed glass facade in the living room, not openable or tiltable in any way.
Stains have formed between the panes, especially when the sun shines on them, and it looks quite unattractive, as if they haven’t been cleaned for a very long time. In fact, I last cleaned them yesterday.
Picture 1 shows large stains, like water spots on the inside of the outer pane,
and in picture 2 you can see very small speckles on the inside of the inner pane.
If you stand very close to the window at the side, you can clearly see that these stains are inside the window, meaning on the respective inner surfaces of both panes and not on the outside. Cleaning on the outside therefore does nothing.
The windows are a bit older, from the 2000s, but I don’t know the exact date. This is the only window in the house where no date is indicated on the frame.
Since these spots are only noticeable up close or when the sun shines directly on them, it’s not a huge problem but not very nice either. It would be frustrating if this meant the insulation had failed (?).
Does anyone have an idea what this could be?
Thanks

Did you notice this last winter as well? Did you see moisture/condensation/fog between the panes?
If so, the seal around the edges of the two glass panes is defective. This obviously reduces the insulation performance significantly.
If not, wait until this winter to see if anything appears there. If it does: replace the glass, not the entire window. This is much more cost-effective. Unless the frame is already damaged on the outside.

I believe the stains were already there last winter, but if so, they were definitely not as severe as they are now. Since the sun is much higher in the sky during summer and never shines directly on the window, the stains are hardly visible in summer, which is why I hadn’t thought much about them for a long time. I will provide an update once the window installer has been there.
