Acoustic Privacy: How to Choose the Right Glass for Your Conference Rooms

In the age of open-plan offices, conference rooms are the last bastions of privacy. However, a glass wall is only as effective as its acoustic rating. Here is how to achieve silence without sacrificing light.

Understanding STC Ratings

Sound Transmission Class (STC) is an integer rating of how well a building partition attenuates airborne sound. For a standard conversation to be muffled, you need an STC of at least 35. For full confidentiality in boardrooms, Meaven Designs recommends systems reaching STC 42 or higher.

Single vs. Double Glazing

While single-glazed 12mm toughened glass is beautiful and slim, it typically tops out at STC 32-34. For sensitive areas, double-glazed systems with an air gap are essential. The air gap acts as a buffer, significantly reducing high-frequency noise from the office floor.

The Role of Laminated Glass

Laminated glass contains an acoustic interlayer (PVB) that damps vibrations. This is the "secret sauce" for high-performance partitions. At Meaven Designs, we often specify acoustic-grade laminated glass for coworking focus rooms to ensure zero sound leakage.

Don't Forget the Seals

Acoustics is like a water tankeven a tiny hole will leak. Drop seals on doors and high-quality perimeter gaskets are non-negotiable. We ensure that every joint in our installation is hermetically sealed with premium silicone and specialized acoustic extrusions.
