Acoustic Performance and Privacy Considerations

Acoustic performance and privacy are core considerations of anyone designing an office, and glass walls aren’t without limitations in this area. However, a deeper understanding can help you make informed choices, ensuring you’ve selected the best glass wall product for your desired application.

Understanding STC Ratings

Sound Transmission Class (STC) ratings measure how effectively glass walls reduce sound transmission. Each 10-point STC increase represents roughly a 50% reduction in perceived sound transmission.

Addressing Common Acoustic Challenges of Office Glass Walls

Glass walls inherently provide less acoustic isolation than traditional construction, making proper system selection crucial for an effective space. 

How To Improve Acoustic Performance of Office Glass Walls:

1. Specify double-glazed systems for private areas
2. Use proper gasket and seal installation techniques
3. Consider ceiling-to-deck installations for maximum isolation
4. Integrate acoustic ceiling treatments above glass wall areas

Privacy Solutions Beyond Acoustics

Visual privacy concerns often drive decisions regarding glass wall specifications. Beyond acoustic considerations, visual privacy impacts employee comfort and space functionality.

How To Improve Visual Privacy of Office Glass Walls:

1. Electrochromic smart glass for on-demand privacy
2. Gradient frosting for selective visual screening
3. Adjustable lever systems within glazed cavities
4. Strategic placement of furniture and screens
