Combining aesthetics and functionality, to optimise the use of the living space, was the aim of ADL in designing the bifold system: the opening of the pair of doors is almost complete to minimise the overall dimensions.
The practicality lies in the two rails: one on the ceiling, which also includes the rotating hinge for the first door. The second, optional, is integrated with the floor to open two or three pairs of doors.
The built-in or recessed handle, like the X5 model, ensures the complete neatness of the architectural system, making the bi-folding sliding doors fluid.
