Their aluminium side frames are less than 2cm wide, barely disrupting views when the doors are closed. When the doors are fully open, they rest at the edge of the opening, enabling maximum walk-through width.
This is achieved by opening the first door (or window!) as usual, then sliding susequent doors across the open space and opening each of them outwards or inwards, depending on your installation.
