Fresh air and hardly any noise pollution. This is achieved by the well thought-out tilting function of the GEALAN Hafen-City window®. With tilted windows, the system achieves sound insulation of up to 34 dB, achieving the best values in the certification by the ift Rosenheim.
The "GEALAN Hafen-City-Fenster" achieves a sound insulation value of up to 63 dB when closed – better than the sound insulation levels attainable with traditional windows and sound insulation glass, which only go up to 48 dB. Even when the window is partially open, the GEALAN system still achieves sound insulation of up to 34 dB, which has earned it the best ift Rosenheim certification rating.
The "GEALAN Hafen-City-Fenster" is a combination of the GEALAN-KUBUS® and GEALAN S 9000 systems. Both individual elements have been brought together to form a single unit, using an assembly frame developed in-house. Rotary opening to the inside makes the windows easy and straightforward to clean; essentially, the tried-and-tested principle of the box window has been applied to a modern window design. So now, developers and contractors have a solution available that enables them to combine modern architecture with the highest standards in soundproofing and natural ventilation.
Another advantage of the "GEALAN Hafen-City-Fenster" is the fact it can be easily cleaned from inside the room; essentially, the tried-and-tested principle of the box window has been applied to a modern window design.
The "GEALAN Hafen-City-Fenster" maintains a quiet environment even more effectively when it is closed, achieving a proven sound insulation value of 63 dB and so keeping offices and apartments free of transport noise.
