Cecil, My husbands shop has 3 doors that align in a row. The front door, door to a back room and the rear door to the outside. I have read that a "screen" should be put behind the middle door. Can this "screen" be open work like lattice, or should it be solid? If solid, can it have a window or opening so someone in the back room can see a customer entering the front door? Would an opening be OK if it was a one way mirror? Also the bathroom (toilet & sink) are in the SE corner. Anyway to "fix" this short of moving it? Thank you for your help Judy
