FS-In folding doors

This folding systems allow sashes to be folded and pushed together on one or both sides toward the center of the room.

The FS-In folding system – when opened – provides unrestricted space without construction posts. Standardly installed rails with carriages at the top and bottom of the window frame along with specially designed hinges, ensure smooth and effortless operation. Folded sashes are held in place by special system holders. The FS-In system allows creating of very large (non-standard) glazings.
With the folding system, you can choose between a standard window threshold or a low threshold.
