My living room and dining room are connected and I wanted to know if anyone have any ideas for closing bad the living room to use the ac. I've considered a large curtain but not sure if that will do the career. The opening is 8 ft loftiness by 6 ft width. I would prefer something that wont cost alot since I dont reckon I will be making this a permanent residence.
Answers:    Would custom bi-fold doors work? You could bring back them in the size you involve and then paint them to meeting anything.
Maybe a curtain or drape that is for omission heat and or wispy.
