High interacting wind loads, movements of the building, driving rain and high levels of noise pollution pose major challenges for weathertightness and comfort when it comes to sliding systems in high-rise residential construction. The solution lies in the gasket.
air-lux have developed patented pneumatic sealing technology with a membrane-like function to guarantee consistently high performance. This technology is at the core of the new Schüco AS AL 75 sliding system (Aluminium Sliding air-lux, 75 mm basic depth), which was developed in collaboration with air-lux. The sliding system is intended for high-rise buildings in particular and features impressive weathertightness, design, smooth operation and sound reduction, winning the Red Dot Design Award 2022.
The high dead loads of high-rise buildings can lead to lintel and sill settlement, thereby causing building movement. This poses great challenges with regard to the weathertightness of the opening units. Wind and earth movements can also cause the building to vibrate. If the wind loads on the ground floor of a non-exposed apartment block in Europe have a positive wind load of approx. 100 kg/m² and a negative wind load of 85 kg/m², these are doubled to approx. 200 kg/m² positive and 170kg/m² negative wind load on the façade of the 17th floor. The patented sealing technology by air-lux was designed with these specific challenges in mind and functions using air, providing a 10-year guarantee.
Principles of the patented pneumatic sealing technology
When the sliding system is closed, air is pumped into the gasket at the touch of a button. The compressor required for this is concealed in the top outer frame. The gasket inflates with air to fill the gap between the sliding vent and outer frame, staying in place even if the sliding units move. The amount of air in the seal is automatically adjusted as required, ensuring that the Panorama Design sliding system is always 100% weathertight.
When the sliding system is open, pressing the button again releases the air from the gasket, which then becomes inactive and returns to its rolled-up starting position. The sliding system can now be smoothly opened and closed again. No additional tools are required for fabrication or installation.
Design, comfort and security – the Panorama Design sliding system
Elegant aluminium profiles in the Schüco AS AL 75 Panorama Design sliding system extend the living space by creating a fluid transition to the outside. The system can be installed flush with the floor and ceiling as well as at the side in the reveals, creating a level threshold for barrier-free access. Large units with heights of up to 6 metres and widths of up to 8 metres can be installed and operated via an optional, automated, concealed drive.
The sliding system also offers impressive sound reduction to 44 decibels, wind load resistance to Class C4/B4 (in accordance with EN 12210), weathertightness to Class E1500 (in accordance with EN 12208) and burglar resistance to RC 3. The Schüco AS AL 75 sliding system can be connected to all standard building management systems, making it highly convenient. The system can also be controlled via a mobile end device.
