I'm surprised glass can support the weight of those things.

Window shakers sit on the sill and that carries most of the weight,
The window frame keeps it from falling out. The new ones are really
pretty light and they don't actually "shake" much. Some of those old
ones took two people to pick up and they rattled the pictures on the
wall when the compressor shut down.
