"Put these up across a double set of sliding doors. ( 4 windows) Took a while to figure out the installation, and then everything went up as planned. We mounted to the ceiling, so it was like an inside mount. It took us two afternoons to get them up, but they look nice and function as we expected. if you want the floor to ceiling look follow the inside mount directions and hang from the ceiling instead of the inside of the window frame or the wall."
