Fogging between glass panes

[tduffett60]

We had Imperial windows installed in our home about twenty years ago. Several of them seem to be clouding on the inside between the sheets of glass. My question is, is this repairable or is the only solution to replace the windows?

It is repairable but most often times, when you reach the 20 year mark it makes more sense to replace the windows.

You mentioned Imperial windows. Is that the manufacturer or the model? Are they still under warranty? That would be best to figure out first.

The Imperial name is stamped on the window closer, I can only guess that this is the manufacture. There is no info on the installer so I doubt if there is any warranty. Thank you for your reply.

The installer would have nothing to do with fogging between the panes of glass and he would have nothing to do whatsoever with any fogging.
The manufacturer is one that i never heard of and i doubt they are still in business . if they are, i highly doubt they would replace the window after 20 years.
Today, some of the higher end manufacturers offer much better warranties and actually honor them.
You can try contacting a window repair company or glazer, perhaps they can install new panes.
That said, at this juncture, it may make more sense to replace the whole window.

Imperial is probably International Windows. They are still in business but have been purchased a few times and I know there is no warranty. If you are otherwise happy with the windows, you can have a local glass company replace the IG units.

get a price on replacing the IGU.
Then decide which path to choose.
