We have a bedroom with 30-inch x 7-ft opening that takes me to a bathroom and a closet. This opening is ideal for a door, but it's solid concrete and very difficult to drill.
So I was thinking of putting something that would cover this hole, but is easy to install. I was thinking of an accordion door or something very simple, but I don't know if these exist for this type of application. I prefer not having to drill a frame into the concrete.
This connects to a bathroom, so there's no need for something as sophisticated as a door. The only reason I wanted to cover it is because the bedroom has an A/C so the air escapes to the bathroom and closet, and it becomes very inefficient.
Any suggestions are appreciated.
