Re. “Mysterious rooftop figure a reminder to lock up,” August 17.
Windows should have a lock that holds them partially open.
On a typical cheap sliding window that’s another slot in the sill, same as the one for the closed position. (Keeping the window closed won’t help if that lock is not in place. A wooden or metal bar in the sill track can also be used to stop the window from being opened far. I use both the lock and bar.)
A trap few people know about is that a typical sliding aluminum window has to be blocked at the tip after the sliding part is inserted into the frame. The ones I’ve seen have metal u-clips that have to be slid into position. Otherwise the window can be removed by lifting, the reverse of how it was installed.
I don’t know what “security screen” means, I presume a heavy duty screen that is screwed to the frame from the inside.
