Effective
noise protection

Acoustic glass

Acoustic glass effectively reduce the penetration of outside noise into building interiors, providing acoustic comfort. Properly selected insulated glass units can reduce sound levels by up to several dozen of decibels.

Acoustic comfort

Ensuring adequate acoustic comfort requires effective noise protection. It is assumed that reducing the noise level by 10 dB inside the building compared to the surroundings gives the impression that it is reduced by half. Where it is not possible to eliminate the noise source, soundproof glass is used.

Determination
of sound insulation

Acoustic insulated glass units are constructed on the basis of the asymmetry of the glass, their flexible bonding and the use of attenuation gases in the space between the panes. Insulated glass units - depending on the type of unit - achieve acoustic insulation within the limits of Rw=28-53 dB.

In defining the sound characteristics of building partitions, a acoustic insulation coefficient (Rw) and correction factors (C) and (Ctr) are used. They provide the average number of decibels attenuated by the partition in the range from 100 to 3150 Hz, without specifying the exact attenuation level in subsequent bands within the given frequency range. PRESS GLASS possesses certification for soundproof glass with an acoustic insulation factor ranging between 31 dB and 52 dB.
