If you are looking for a glass office partition to achieve an acoustic performance the guide below gives indicative levels of what can be achieved using configurations of glass thicknesses in single or double glazed applications.
There are many factors that can affect the performance of a partition wall including flanking sound travelling above a suspended ceiling, air grills, conditioning ductwork and transition details between walls. Most tested systems will tend to perform up to 5dB better in a test environment than in an installation. Please contact our experienced staff who will be pleased to provide assistance.
