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.
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.
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.
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)
- Access required for service work
- Dimensioning of the technical room by air-lux
When open, no threshold is visible. Whether parquet, slabs or stone: the materiality of the floor can be adopted.
The unique air-lux sealing concept with all-round inflatable ring seals guarantees 100% tightness against driving rain, wind and noise.
Air is pumped into the seal by pressing the button. The gap between the slider and the fixed frame is closed absolutely tight.
By pressing the button, the air escapes. The seal returns to its original, rolled-up position, and the window opens quietly.
