polycarbonate (Lexan) to replace windows?

Some of the shops that repair dual pane windows are now offering a thicker single pane window for replacement. The cost are about the same. The advantage is..........no more fogging, and the insulation value is about the same. Even though I have them, I think dual panes are ridiculous in a motor home. Any honest shop will tell you they eventually will leak. Besides, we all have a huge window across the front that is NOT dual pane.

I found that totally separating double pane windows was not necessary. I'd cut the spacer out of the top and bottom, leaving the sides to maintain the 'structural integrity' of the glass 'sandwich'. I'd pull a small rag back and forth inside the window (with a pull wire) until clean then replace the top and bottom spacer and reseal. Much easier and faster. I used a polishing compound as a cleaner. Double pane are so much better than single. Even more so than in a house..in a house you usually are not sleeping with your head 12" from a window....

Yours are probably using plexiglas or it is not out in the sun very often.
Yellowing of Lexan is a well known issue and has been for years. I doubt if you are the one in a million exception.
I used to own a sign company and in Florida we could figure a 5-7 year life for Lexan before yellowing and cloudiness.

There are several repair videos available. It may be easier and cheaper to repair the windows.

I agree with garyemunson. Having repaired some fogged windows in my RV, I believe it is much more effective to clean and reseal the dual pane windows properly.

Search the forums. If your double pane windows are just foggy and you are thinking/capable of replacing them yourself, you can fix what you have and get rid of the fogging.

Lexan (polycarbonate) doesn't do well in direct sunlight. As was previously posted it yellows. Look around for a company that repairs dual pane windows. there is one in Hudson, FL, somewhere in Arkansas (I forget), and several others around the country.

It is legal to replace your side windows with Lexan BUT, this is the same material that turns yellow and gets cloudy on the headlight covers on most automobiles. The more it is out in the sun, the sooner it will turn yellow.

there are a dozen other places the first responders can break in. but you evidently have double pain windows and do you want to replace them with single pane? and yes, I would guess that a single pane of lexan would be much more expensive than a pane of glass. I would guess that making double pain windows out of lexan et.al. would be cost prohibitive. I don't know the law on non-shatterable glass windows in a motor vehicle however.
