I love my bi-fold doors which run the width of the house at the back but if you want air in the living room you have to open the door at one end. The bi-folds are 5 panels with 3 glass panes in each one - would it be possible to have the top pane on one of them replaced with an opening window - there is enough room for them to fold with a window catch not getting in the way?
Anyone had this done retrospectively?? Would it work or be mega expensive? Frames are white UPVC
Thx
