How silenzio works

With silenzio, we offer a unique way to reduce noise and guarantee fresh air!
Ideal for Renovation & commercial new build or conversion

closed VS open window

When closed, the air (optionally with low-noise fans) circulates from top to bottom. This ensures a constant supply of fresh air with a noise reduction of 53 dB. The existing window is closed in this state.

When the existing window is open, a sound reduction of 36 dB (silenzio + double insulating glazing) is achieved.
