General awareness of noise hazards is low. However, excessive noise exposure causes severe health effects. Nowadays, when people spend most of their time indoors, it is worth considering noise protection using acoustic glazed units in civil engineering.
The perception of noise indoors is subject to the following rule – if the noise level in a room is reduced by 10 dB against the noise outdoors, it seems to be reduced by a half. When choosing the right sound insulation, one shall always identify the source and level of noise so that a glass set with relevant sound attenuating parameters could be selected.
PRESS GLASS constantly develops its range of acoustic glazed units. Our portfolio has gained another 6 glazed units with certificates confirming the values of Rw coefficients at 41-51 dB. The list of new panes is presented below.
