Acoustic insulated units
Protection against noise
Protection against noise is one of the most important issues in our lives.
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 situations the use of acoustic insulated units can offer a way to reduce the noise coming into a building, making it more comfortable for the occupants.
Acoustic insulated units are constructed based 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 insulated units can achieve the acoustic insulation factor STC, 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 STC and outdoor-indoor sound transfer coefficient OITC. The coefficients states the number of decibels suppressed by the glass and does not describe the frequency band but gives an average suppression value within the 125 (STC) or 80 (OITC) and 4000 Hz band. PRESS GLASS possesses North America certification for sound absorbing glass with an acoustic insulation factor STC ranging between 33 dB and 52 dB.

SOUNDPROOF GLASS CONFIGURATOR
Easy to use configuration tool:
- selecting acoustic glass units by acoustic parameters,
- saving selected parameters and units to PDF file for future reference
NOISE DAMPING SIMULATOR
An intuitive-to-use simulator enables:
- simulation of noise reduction through the use of acoustic glazed units in relation to the noise heard without any sound barrier,
- quick comparison of auditory effects between all offered acoustic glazed units,
- limiting a comparison to single glazed glass, double or triple glazed units,
- selection of six characteristic types of noise.
