Sash windows

Sash windows, unlike normal windows, do not turn or tilt, they just slide up offering many advantages and different possibilities of uses.

Operation can be either manual or with electric drive.

Maximum utilization of space No need to clear up the window sill before opening the window; there are other window models that feature wide possibilities of openings, but they always require space for opening in front of the window; this space is not usable for seating accommodation or decoration
Very wide openings are possible
"Inside" and "Outside" - no defined spatial separation. Who doesn't appreciate the unique ambience of a side-walk café?
Safety: the counter as a barrier and protection from open access
Selling "in the street" - attracts occasional customers
No need to rent large premises
Efficient ventilation possible - catchword "batch-ventilation"
