We have a 2+ garage. It is standard width and the extra is in front of the cars. In front of one stall is a permanent closet and bathroom and nothing in front of the other stall. We currently have a curtain from the closet to the opposite wall. There is a small window a/c and small heater in that end and the idea was to be able to work comfortably in that area year round. However, even with weights in the bottom of the curtain, it blows around when the a/c is on and is horrible on really windy days.

Any ideas on a more fixed, yet movable wall? Movable so when the whole garage is needed as shop, the wall can be opened, or when a smaller area is needed to keep a project clean or cooler, it can be closed.

The width of the opening is about 14 feet.
