The SL 23 sliding system provides comprehensive comfort, even in challenging conditions, thanks to its expanded installation capacity of up to 17 mm glass thickness. For example, it is perfect for use in balcony and facade design, and is just as suitable for use as a partition for high storey heights. Like the SL 20, it can also be installed in a glass house for flexible wind and weather protection. The sliding panels of the all-glass system run along a multi-track, flat floor track. This guarantees an accessible transition to the outdoors.
