The first sliding window system for high-rise buildings: air-lux passes impermeability tests in the USA

News Corporate

air-lux sliding windows have recently undergone specific tightness and earthquake tests in the USA, to test the use of sliding windows in high-rise buildings. We are pleased to report that the air-lux sliding windows have passed all these high-rise tests with flying colors! This makes them the first sliding windows ever to be suitable for high-rise buildings with their enormous wind loads!

Sliding windows not yet suitable for high-rise buildings

High rise experts have so far expressed the opinion that sliding windows are not suitable for high-rise buildings because of the high demands on tightness and the limited possibility of absorbing building movements. The conventional sealing systems known to date for sliding doors are not suitable for this type of application and have often led to sealing problems in the past. Although the installed systems fulfilled the tightness requirements according to their test results, they failed in practice because construction movements, building subsidence and tolerances were not taken into account.

However, the air-lux air sealing system sets new standards in terms of tightness / impermeability. Thanks to the high contact pressure of the air seal and the absence of labyrinth seals, all requirements for tightness and structural recesses can be met without any problems.

Toughest tests for sliding windows in high-rise buildings

The USA is considered to be the country with the highest requirements and toughest tests regarding tightness requirements for high-rise buildings. To ensure that the air-lux sliding windows meet the high requirements of the USA, the well-known air and water tightness tests as well as life cycle and earthquake tests were carried out. In the latter, the window elements are diagonally warped up and down. The tightness must be guaranteed at all times.

The best sliding window system for high-rise buildings

It is no surprise - air-lux passed all tests with flying colors! The required 12 psf pressure (12 pounds per square foot is 574,563 Pascal) for driving rain tightness was not only passed by air-lux, but with 20 psf (957,605 Pascal) even exceeded by far. air-lux is thus the first sliding window system worldwide to pass these tightness and earthquake tests. The general expert opinion that sliding windows are not suitable for high-rise buildings has now been refuted once and for all. Now we can proudly say that air-lux is the best sliding window system for high-rise buildings!

The high-rise building at 150 Seaport Boulevard

This unique building directly on the Boston harbor impresses at first by its architectural design. The famous architect Howard F. Elkus of Elkus Manfredi Architects was inspired by the sea and designed a tower that resembles billowing sails. The magnificent glass sails rise 76 meters into the air and fan out towards the water. The owner of the residential tower is the luxury hotel chain St. Regis. It is having 114 high-quality residences built on 22 floors, all with private balconies and a wide view of Boston and its harbor.
