I have not seen an RV window with shades between the panes EXCEPT for entry door windows, but they don't open. I do know Lippert has dual pane, but they don't make them, and Pelland has dual pane from multiple manufacturers. RecPro has windows, but I think they are single pane. All will come with screens. I used RecPro to replace the half fixed, half tilt out window on my pop up camper. All of the RV windows I have seen are tempered, I think that might be some sort of law when it comes to vehicle glass and crashes
