double pane window

Double pane windows are fine. But, as with house windows especially in the sunbelt states, Low E is very important. That is where Argon Gas is located in between the panes and stops the majority of the heat entering due to the extreme sun. I am wondering if double pane Low E windows are made for RV's?

Not that I'm aware of. Problem with that idea is that the gas would quickly leak out as an RV is a house getting banged around while driving. The windows would leak because of the racking that goes on almost continuously while on the road. I imagine all the gas would be gone within a few weeks. Double paned windows don't really need to be fully sealed to do a good job, they just need a dead air space to accomplish their purpose. So a leak or two in a common RV type dbl paned window is no big deal.
