Descending window – the window that disappears into the ground

At the touch of a button, the entire window front magically sinks into the ground, merging the interior with the exterior. The air-lux descending window is not just a glass front, but a highlight all year round. It is not without reason that the descending window was awarded the German Design Award 2020 in the category "Excellent Product Design - Building and Elements".

The original descending window turns an air-conditioned building with transparent walls into a covered pool terrace at the touch of a button

Convenient operation, maximum security

The descending window is operated by means of a dead man’s control, i.e. by constantly pressing a pushbutton. On request, fully automatic control is also possible, in which case safety is ensured by radar or infrared.

Dimensions

Big is good – bigger is better! There are almost no limits to the size of descending windows. The size of a drop front is only limited by the maximum possible glass sizes. These are:

Standard glass: 3 × 6m
Special glass: 3.5 × 20m

The larger a descending window can be realized, the more impressive the effect is when it is open. At present, we are installing the largest drop window system ever built, a full 16 meters long and 3.15 meters high, for a residence in the Gulf region. The special glass is installed as a laminated pane without mullions in the lowering frame and allows a 60 m² view of the sea.

Various glass thicknesses can be installed, and safety glass with bullet resistance is also possible.

Perfectly balanced

The descending window stands on a stable framework, which is connected to a counterweight. Due to the counterweight, the descending window is perfectly balanced and can be moved up and down silently with the help of an electric drive.

Technical room

Since the descending window completely disappears into the floor, enough space is needed underneath the glazing.

Space for all technical equipment (control system, motor, drive shaft, counterweight)
