I'm looking for opinions on what to do with an old, sliding glass patio door in what will be the right wall (back of the room) in my basement home theater. You should know that the door does not work well, and we rarely use it. I don't see us using it at all once the theater is finished. I guess my options are: use a curtain, and hope the light leak isn't too bad; blackout (paint?) the glass somehow; close off the opening with drywall; replace with a new door or doors (haven't seen any solid doors that fit in this 72"x80" opening); or use some kind of combination (blackout the glass and hide behind a curtain). I guess I could also have building code issues if I interfere with door function. Anyone have experience with this problem?
