minimal Sash Window System

The minimal aluminium framing of the minimal windows® large sliding glass doors is also available as a large, contemporary vertical sash window. This vertical sliding window system creates large horizontal openings that are ideal for creating striking glass facades, including double-height glazing installations.

Specification Information

Vertical sash windows are the perfect addition to any contemporary architectural design as they are able to slide open at the centre, creating a unique opening. Due to the large sizes of these vertical sliding windows, it is the perfect system to create a full glass façade for double height spaces.

Thanks to the full thermal break within the frame and the high specification of glazing used, these vertical sliding windows have high levels of thermal insulation, solar protection and transparency. A number of different glass options are available to provide you with the performance you need.
