Acoustic glazed units

Protection against noise

Protection against noise is one of the most important issues in our lives. The condition of assuring appropriate comfort and sometimes living in a given place is the assurance of a low level of noise.

Our subjective perception of noise is subject to the following principle: if the level of noise in a room is reduced by 10 decibels with relation to that outside, we get the impression that it is reduced by half. Noise protection must be applied everywhere where noise cannot be completely eliminated. In such applications we are faced with acoustic double glazed units.

Acoustic double glazed units are constructed basing on the asymmetry of the assembled panes of glass, flexible bonding of the panes, and the use of attenuation gases in the space between the panes. Acoustic double glazed units can achieve the acoustic insulation factor Rw = 30 – 53 dB, depending on the type of unit. Before choosing a suitable unit, the source of noise should always be specified and other influential factors should be identified. Therefore, in all cases customers should contact us during an early planning stage, so that all specific requirements for the glass can be taken into consideration by our well qualified staff.

When defining the source of noise we use the so-called acoustic insulation coefficient Rw and corrective coefficients C and Ctr. Rw states the number of decibels suppressed by the glass and does not describe the frequency band but gives an average suppression value within the 100 and 3150 Hz band. PRESS GLASS possesses certification for sound absorbing glass with an acoustic insulation factor ranging between 31 dB and 52 dB.
