When we had ours done they did not take the window apart. Cut out the slider in the same manner that you cut out the fixed portion. Good luck…BTW, make sure that you press the rubber strip seals in place well, and check them both (inside & outside) often. They are made of unobtanium (see other posts on the forum about sourcing them), and will work out of the channel because of the difference in thickness between the old double pane and your new single pane glass until they adjust their “memory”.

I had the door and the driver window on my H replaced by Tradewinds. Kyle had the windows in stock. Professionally done, looks original. Been 9 months or so and no problems so far. (386) 848-4466

Prevost has had an issue with double pane window fogging for a long time and the problem does not go away. If you catch the fogging early you can separate the panes, clean the glass and reseal them. The last time I did that I got the glass as hot as I could so when I pushed the two panes together and the seal was complete, as it cooled there would be a slight vacuum between the two. My Mickey Mouse self repair outlasted the factory replacements I bought previously.

Jon: Was it a permanent solution?

Define permanent. It lasted longer than the new Prevost windows I previously bought, but how long it lasted I do not know because I sold the coach.

The reason the windows fog is because if there is any air or gas in them instead of a perfect vacuum, as the window gets hot the inside pressure increases and as it cools the inside pressure decreases. As long as it is hermetically sealed it will not fog. But as soon as the seal allows even the slightest leakage the window begins to “breathe” with temperature changes. Each time it inhales it draws in the same humid air the aux compressor does. The dry gas or air originally in the window is ultimately replaced with humid air and the result is condensation when the window cools.
