Large Sash Windows
The sliding door system can be designed to create large vertically sliding glass windows. These oversized vertical sash windows are impressive feats of glazing technology, pairing minimalist detailing with smooth action openings.

The large insulated glass units are available at sizes up to 29m2 that slide effortlessly upwards, creating a gravity defying elevation of glass.

The minimally framed opening system functions by connecting the vertically sliding glass units to an integrated and hidden pulley system. Through the engineering of counterweighting the glass panes can slide naturally upwards manually. Even with oversized glass units the system operation can be manual and smooth.

Vertical Sliding Window
With the use of ultra slim frames, these vertically sliding glass walls offer extremely minimal sightlines of only 20mm horizontally. All other surrounding framework is designed to be hidden by the building finishes for a modern yet beautifully simple window design.

These vertical sliding windows offer feelings of traditionalism with the smooth vertical sliding action of the opening. But the slim aluminium framing offers a modern design with sophisticated design and technological precision.

With panel sizes up to 29m2 per sliding pane architects can achieve impress widths of glass openings, allowing the use of minimally framed glazing as moveable glass walls.

As with all solutions from IQ's sliding range, the vertically sliding sash solution offers an architectural resolution that encompasses light and transparency, which is a key element of modern architecture.

 

Vertical Sash Windows at the Showroom
If you would like to see an oversized vertical sash window in a real-life situation, the newly renovated IQ showroom is now home to an automated vertical sash. 

Reaching a staggering height of 6.5m and a width of 3.4m, this impressive vertical sliding window solution is opened and closed at ease with just the push of a button. The motorised cantilever that is used for the automation moves these oversized glass panes slowly and smoothly with a dead man switch making it extremely easy to control. 

The vertical sash was installed alongside an oversized automated sliding door pane, also reaching 6.5m tall. Both systems were finished with a polyester powder coating in a colour known as Axalta Horizon.
