“Will you be able to hear conversations from the next room through the glass partition?” – it’s one of the most common questions we hear from clients planning an open-plan office. The answer: it depends on the construction. Here’s what actually affects the acoustics of a glass partition and what to expect.
What affects a partition’s sound insulation?
The level of sound reduction a glass partition provides depends on several factors combined, not just “thick glass” alone:
- Glass type and thickness: a single pane of tempered ESG glass gives basic insulation; laminated VSG glass with an appropriate acoustic film reduces noise more effectively.
- Number of panes: a double-glazed system (two panes with an air gap between them) provides noticeably better sound reduction than a single pane – that’s exactly why, for higher acoustic requirements, we recommend a double-glazed system instead of a frameless one.
- Profiles and seals: even the best glass won’t help if the aluminium profiles and seals around the pane aren’t airtight – that’s the main “escape route” for sound.
- Doors in the partition: if the partition has a door, it’s often the door – specifically the threshold and panel seal – that determines the real sound reduction of the whole construction.
What to expect in practice?
A frameless partition made from a single glass pane provides visual privacy and reduces noise to a level similar to a standard drywall partition – enough to muffle a lowered-tone conversation, but not eliminate sound entirely. A double-glazed system, with a properly selected acoustic pane, approaches the sound reduction of a full masonry wall – important for meeting rooms or offices where confidential matters are discussed.
When is it worth investing in a double-glazed system?
- Meeting rooms and offices where confidential conversations take place;
- Open-plan offices with many workstations, where background noise levels are high;
- Rooms near busy corridors or lifts.
In other cases – e.g. dividing work zones without high confidentiality requirements – a frameless system is usually fully sufficient, offering a better visual effect and lower cost as well.
