For your sister's Alcan window, I recommend our S380-37 side load balance with a spring strength option 3620. The white nylon top sash guide looks like our 18-161 and is screwed on the side of the sash. You might also need the 16-002 take out clip, if yours are broken. Carefully go over this hardware to confirm that they're the same as yours. We don't make screens, but if you take one to your local hardware store, they should be able to repair or make them for you.
