We are in a bit of a dilemma... We have added a wall to our Lounge to close off and create a Theatre Room. Problem is to retain the 5 star rating we've been told there needs to be a 2100mm wide space in the wall to allow natural light to enter the room. After handover, we were originally going to put a sliding door in to close off - but now believe it is too wide, so bi-folds are the only option... Any ideas?
Also, how difficult is it to install a sliding door into an existing wall/space?
Thanks.
