Manual sliding wall systems offer you "mobile" flexibility for room partitioning. To open the glass partition walls, the glass elements are simply pushed together and elegantly stacked on the side. If the glass partition walls are not to be opened completely, then passage doors in the partition system are your solution. This means that your partitioned rooms can be reached separately even when the sliding wall leaves are closed. The passage doors are then user-friendly single-action or double-action doors.
