PEACE and SAFETY
Since 1990, BELLMANN has been setting standards in metal construction on innovations → here the silenzio ® soundproof window.
Despite the wide-open interior windows, it achieves a noise reduction of up to 36 dB at full
Fall protection – ideal for noisy environments such as streets, flight paths or
Railway lines. When closed, silenzio ® even reduces noise by up to 53 dB, which brings street noise to the level of a whisper.
Assembled within 2 days – from the outside! Central ventilation/air conditioning and flue gas extraction
are replaced by the window. In summer, we guarantee the night-time cooling of the entire building.
