Product description

Sliding sashes have rarely been used in high-rise buildings because sealing sliding windows has always been considered problematic due to the lack of contact pressure of the gasket. The lift-slide or parallel sliding systems used today are also often unsatisfactory in terms of tightness, ease of operation or appearance. air-lux is breaking new ground with its sealing concept and simply moves the seal instead of the heavy sliding element to achieve the contact pressure. This new and patented sealing concept offers a number of advantages.

Concept

Sliding sashes have rarely been used in high-rise buildings because sealing sliding windows has always been considered problematic due to the lack of contact pressure of the gasket. The lift-slide or parallel sliding systems used today are also often unsatisfactory in terms of tightness, ease of operation or appearance. air-lux is breaking new ground with its sealing concept and simply moves the seal instead of the heavy sliding element to achieve the contact pressure. This new and patented sealing concept offers a number of advantages.

The requirements for a sliding window system in high-rise buildings are enormous. The higher the building, the greater the wind loads and the more important is the watertightness against driving rain. Conventional sealing systems such as brush seals or rubber sealing lips sometimes show strong signs of wear after only a short time. This wear is caused by the enormous interaction of pressure and suction to which the seals are constantly exposed.

Highest demands on the seal
Wind loads on the ground floor:
The wind loads of a non-exposed high-rise in Europe on the ground floor are approx. 100 kg/m² pressure (+) and 85 kg/m² suction (-).

Wind loads on the 17th floor:
On the 17th floor, the load on the façade is already twice as high at over 200 kg/m² (+) and 170 kg/m² (-).

Sliding element load:
With a sliding element on the 17th floor of 3 × 3 m, loads of 1900 kg of pressure and 1530 kg of suction arise with the wind loads mentioned.
Since the air-lux sealing concept eliminates the need for complex hardware mechanisms, the system is virtually maintenance-free. This leads to low maintenance costs and an improvement of the ROI (Return on Investment).

air-lux seal with membrane function
Due to the interacting wind loads on the facade (pressure/suction), the sliding wings and the fixed elements bend. With a 3 m high slider and a maximum permitted deflection of one L150, this results in a deflection of up to 20 mm.
Due to its membrane-like character, the air seal adapts to these movements, and the sliding window always remains 100 % tight, regardless of whether it is subjected to pressure or suction loads. In addition, impact noises from the profiles in strong winds are a thing of the past. The constant contact pressure of the air seal eliminates any clearance in the slide.

Sealing with air - the ingenious solution for high-rise buildings
- 100 % tightness against driving rain, wind and noise - on every floor
- air-lux air seal with membrane function
- Constant performance of the air seal without signs of wear
- Low maintenance costs and good ROI (Return on Investment)
