Dual Pain Windows

[214skier]

How important are these?

We bought a 2014 Outdoors RV / Timber Ridge that does not have them. We like to snow camp and noticed that the windows sweat a lot.

I also get that single = less insulation and therefor the air conditioning is less effective.

Welcome your feedback.

They can be a pain when they fail, but sound like a good idea to me.

I installed triple pane residential sliders in place of my outdated windows. They not only do a good job with thermal transfer but the elimination of outside noise is astonishing.
If you want an inexpensive way to insulate the window openings, carefully cut 1"->2" extruded polystyrene (blue board foam) to friction fit the openings. Put a strip of tape on an edge for easy removal. You can at least put the foam board in the openings at night and easily remove them in the day. It will make a big difference.

On our DP with dual pane windows, down to 18*, only the single paned windshield sweats. I wouldn't buy an RV without them.

Nothing you can really do about it now without a lot of expense.
