Firstly, this is definitely a related question: How to install window screen without screen track
But the window from in that question is a bit different, and I don't quite see how the answer can be applied to my window.
I recently bought an older home (1920's) with a glass-windowed porch. These windows are not affixed with any sort of track; They are simply on hinges and swing inward.
They aren't great windows, but whatever, I don't intend to replace them anytime soon. Many bigger fish to fry and whatnot.
However, I do want to get some airflow through the porch, without pets escaping (or letting bugs in).
So far, I was planning to assemble and install a screen frame kit to each window like this one:
The big question here is, how can I mount this thing to my weird, simplistic, trackless porch frame? I don't care if the screen isn't generally able to be opened (apart from repair/cleaning of course). If I mount it into that inner area just outside of the red window (which seems best? It's a tad over 3/4" deep), I don't have any room for a bottom loop latch. Kinda seems like I need a "hacky" solution, which is probably fine, as long as it doesn't look terrible.
