HST windows and doors

Types of sills in HST windows


Ultraglide monorail - the so-called low sill allows for immersing it in the concrete floor down to 36mm (on the inside). Like the ultraglide monorail, it is a single running rail sill. What distinguishes them from each other, is that in the low sill the fixed part is the sash, not the frame. As a result, the glazing area is smaller.


An important feature of the Ultraglide monorail sill is that the fixed part of the glazing is in the frame, not in the sash. Such a solution makes the surface of the glass larger, so there is even more light available in the room.
