This glass is useful in urban areas, where noise levels
exceed 70 dB.
When the noise level is 70 dB, the WHO recommends 
35 dB  of insulation on the facade. However, in our experience, the insulation provided by an older facade
with standard windows is only between 23 and 25 dB. 

One way to improve noise control is to increase the thickness of the glass used.

For better results and guaranteed performance, 
use our single and double pane acoustic glass:
