I'm most concerned about safety and framing these windows in properly so that they are secure. I'm mostly uncertain about how to frame around them so that even significant force won't risk breaking through the framing. These aren't cased like off the shelf windows I'm familiar with, and they're pretty old looking, so any keywords on what I might be able to search by would be extremely helpful.Thanks a ton in advance via /r/DIY https://ift.tt/31ehLQa
