Up to now, sliding windows have only rarely been used in high-rise buildings. The sealing of sliding windows was considered problematic. The reason for this is the lack of contact pressure of the seal.
The conventional lift-and-slide or parallel sliding systems are also unsatisfactory in terms of tightness, ease of operation or appearance. Our sealing concept represents an innovation. Instead of moving the heavy sliding element to generate the required contact pressure, we move the seal.
Constant performance of the air seal
Sliding windows in high-rise buildings are exposed to extreme conditions: The higher the building, the higher the wind loads. Absolute tightness against driving rain is required. Conventional sealing systems such as brush seals or rubber sealing lips sometimes wear out considerably after a short time. This wear is caused by the enormous interaction of pressure and suction to which the seals are constantly exposed.
Since the air-lux sealing concept does without complex fitting mechanisms, our system is virtually maintenance-free.
air-lux seal with diaphragm function
Due to the interactive wind loads on the facade (pressure / suction), the sliding wings and the fixed elements bend through. With a 3 meter high slider and a maximum permitted deflection of one L150, this results in a deflection of up to 20 millimeters.
Due to its membrane-like character, the air-lux air seal adapts to these movements, and the sliding window always remains 100% impermeable, regardless of pressure or suction loads. Sealing with air - the ingenious solution for high-rise buildings
Our advantages at a glance:
- 100% impermeability against driving rain, wind and noise - on every floor
- air-lux air seal with membrane function Consistent air seal performance without wear and tear
- Low maintenance costs and good ROI (Return on Investment)
