Barn door opening windows

[Thegirlwiththeyellowcoat]

Hello, sorry if this has been asked before but I can’t see it anywhere.
I know some people sleep with their barn doors open on hot evenings, we can’t otherwise the dub dog would scarper. Is there any reason there doesn’t seem to be opening windows on the rear barn doors available? I guess something that opened from the bottom on a tilt rather than a sliding window, although anything to get air in would be lovely!

I’ve seen brackets that clip inbetween the door and its normal latch to lock it open 50mm (ish). If you have a screen / front door blackout cover you can leave the front door windows slightly down aided if you have wind deflectors.
