I have a 3m wide aperture to the back garden. I would like to have folding doors across the whole width but not the usual sort of thing you see, for example, here: http://www.sunflexuk.co.uk/folding/timber.php
I want four doors in total. The middle two doors are to open outwards (like french doors) and fold back against the outer two doors. Then I want the outer two doors (when unbolted), to open outwards with the inner doors still folded back against them,to leave the whole width open. This means the inner door hinges will be fixed onto moving edge of the outer doors.
I can't find anyone who supplies these. Maybe they are not safe becuase they would whip about too much. I could design/make it myself, but I'd rather have a comercial system that does the job properly.
