SL 45 bi-folding door

A special feature of the SL 45 bi-folding door is its wide range of opening options: some of the panels can be opened inwards; others outwards. For convenient ventilation, a turn-and-tilt panel can be incorporated. Two sealing systems ensure optimum impermeability to wind and rain.
