My plans include hardware mesh across the entire opening of the window and plexiglass over the window frame itself. That way I can keep the windows open during summer and closed during rain or winter. I don't know if that made sense. But it will be kind of like a normal window for your home.
I did that at first. I put hinges on the plexiglass but then it started to crack. I should have framed the plexiglass in wood. Was happy to switch to a real window as it was much easier to see through. I found some porch or camp windows that switch out to screens in the summer.
