Duo Pane

If you are in the Mesa, Az area, contact APR-RV. Contact Michael! We had quite a few repaired while we were at APR-RV for our roof work.

If there is moisture between the panes your window has failed. There is no DIY fix.

Time for either a new window or contact one of the few companies that can rebuild them. I think there is one in Florida that is popular, I don't remember the name.

Theory is to drill through the spacer and seal between the 2 panes. Not to drill through the glass itself. As a note, tempered glass is not that hard. Break a glass bottle then take a sharp piece of it and you can easily scratch tempered glass. Tempering the glass does not make it hard. It allows the glass to flex without shattering and if it does break it doesn't break into a bunch of long sharp shards of glass. It breaks into smaller pieces that create a mess but aren't nearly as dangerous as untampered glass.

Dehumidifier works wonders. Difference between inside and outside temps, people breathing and living in and cooking in such a small area creates a lot of moisture that has to go someplace. Drilling weap holes is not the best solution, dehunmidifying the air is the correct solution.

Humidity inside or out should not cause condensation between the panes of glass. The seal has failed allowing outside or inside air between the 2 panes. Drilling a hole requires removing the glass and it's not a cure. Cure is to remove the window, separate the two panes and replacing the spacer/seal. Been there, done that. It can be a DIY job, I did ours, but it's not a simple task. There are companies that repair them.

I'm not sure high humidity is the cause of moisture between panes of glass. ON the glass, yes.
