foggy double pane windows on class A- help

Thanks for the update. Your method worked, it was quick, and inexpensive. I'm sure it will help others.

well I ended up doing a DIY fix that worked out well. I removed the window from the rv and placed it on sawhorses. Then i taped up the inside pane completely with duct tape, and took a center punch and tapped it a couple times, hard enough to shatter the tempered glass. It pulled out with the tape leaving just a few pieces to vacuum up with the shop vac. It apparently had been fogged quite awhile as the outer glass was etched and would not defog with just window cleaner. I took some very fine grit sandpaper (1500 grit) and wet sanded the glass lightly. Followed up with turtle wax rubbing compound applied in a straight line motion instead of circular. Wiped clean with a damp paper towel and it looks great. Finished by removing the worthless rubber gasket around the frame and applied pro flex sealer instead.

Hope my experience helps someone else

If your dual pane window is just held in place with a rubber gasket, you're very lucky. I think you will have to remove the window, remove the plate and screws holding the ends of the window frame together, pull the frame apart slightly, and then you can get the dual pane glass out of the frame. At this point, you've done 30% of the work of fixing the window. If you want to see what is involved, look at my download file on IRV2 in the files - exterior section. There are some pictures of getting the window out of the frame.

You could do a temp fix by removing the window, cutting them apart, cleaning them (if they are not etched), and reusing the original spacer and gluing them back together. This will last for a while, but without new spacer and the proper sealant, the fogging will return. The file reference above on IRV2 has a source for the supplies also.

Good luck with your fix.

Maybe you waited to long. Not much time for repair or replacement.

You can but you are going to have to come up with a way to hold the other pane in. They are set in a mastic and getting them apart is not going to be easy but it can be done.

There is a place in New York State that will do the same but since you are keeping your location a secret I am keeping the places location a secret

This doesn't answer your immediate question, but if you're in the Washington area, Windows in Motion of Vancouver, WA will build and install new windows for you. They can also build new frames and screens right there in their shop. We had them replace all of our frames, glass & screens and there was a lifetime warranty if they should fog up again. I understand there's a similar shop in Florida, but I don't know their name.

Since you don't say where you are, there is a place in Hudson, Florida that will let you camp at their location, free of charge, while your windows are repaired. For two windows it can usually be done in one day.
