We have a room with old aluminum windows. I’ve included a picture of the windows.
We have an A/C in this room, but these old windows never close tight, so most of the cool air escapes through those windows.
I’m looking for a roll-up curtain or something insulated that will prevent the cool A/C air from leaking through the windows. But this something should be easy to open and close since I open these windows daily.
What would you suggest?
