FSW is a movable glass wall system, visually and functionally similar to HSW. The door rails are connected to one another at the top and bottom by hinges, and its panels are suspended at the end of the top rails. The closed wall transforms effortlessly into a compact parked stack when required – without the need for a separate stacking track. Offset-hung panels allow stacked panels to hang entirely to one side or the other (for FSW-G) or centrally hung panels can be stacked taking up only half the space inside and out (FSW- C).
