Sound reduction window for natural ventilation while reducing noise from outside

The Schüco OpenSilent AWS 90 AC.SI window system is a new system solution for reducing noise while providing ventilation.

In the tilt position, this single-skin window solution has the outdoor air flow in through pre-assembled ventilation cassettes inserted in the upper outer frame. This significantly reduces the noise levels. This results in sound reduction of up to 34 dB while providing natural ventilation. Moreover, the acoustic window offers optimised thermal insulation with thermal transmission of 1.2 W/(m²K), with a face width of just 117 mm. In comparison with the production of a standard window, the Schüco AWS 90 AC.SI requires just a few extra working steps, and the system can be easily combined with fixed lights.

Whether it is the loud droan of a landing plane, the rumble of engines from passing road traffic or the constant rattling of train tracks, ambient noise can be made up of a wide range of noise sources. The effects of noise should not be underestimated, in particular for home and office routines. For instance, guidelines from the World Health Organisation (WHO) warn that ambient noise negatively impacts on a person's quality of life, their general sense of well-being and their mental and physical health. However, the need for housing in integrated urban locations is growing and, as the volume of traffic increases, so too does urban noise pollution. As a result, there is an ever more apparent need to find better ways to reduce sound when planning new buildings in urban spaces. A synergy of sound-reducing measures in the building is needed in order to prevent the impacts of noise pollution on our health.

In a survey of more than 2000 architects and developers, the Schüco AWS 90 AC.SI sound reduction window impressed across the board. The system took bronze in the category "Best product innovation – Finishing" at the ARCHITECTS‘ DARLING® Award ceremony.
