GEALAN HAFEN-CITY-FENSTER NL

The window system for perfect sound insulation: GEALAN Hafen-City-Fenster NL achieves a sound insulation value of up to 53 dB when closed. These values are many times better than those of standard windows with soundproof glass. Fresh air and hardly any noise pollution. This is achieved by the ingenious tilt function of GEALAN Hafen-City-Fenster NL. When the tilt windows are open, the system achieves sound insulation of up to 34 dB and thus achieved the highest values in the ift Rosenheim certification. Especially for the Dutch market, this solution can also be used for the "deaf" facade, a reduction of 11.8 dB between the two frames. This is where GEALAN Hafen-City-Fenster NL is used: inner-city residential areas where people do not want to do without natural ventilation despite increased noise emissions. The window concept is therefore a response to the increasing building density in large cities. It offers excellent sound insulation with closed and partially open windows. Particularly interesting for building owners and architects: The facade appearance is retained and the highlight lies between the frames, a modern window system that combines natural ventilation and sound insulation.
