1. Glass Thickness & Density | Thicker Panels (10mm+) provide better mass law sound insulation,
reducing mid-to-high frequency noise. |
Laminated Glass (PVB interlayer) dampens vibrations better than
tempered glass alone. |
Weight vs. Performance Balance: While thicker glass improves
acoustics, consider structural load capacity and cost. |
2. Double Glazing for Superior Soundproofing | Air/Gas-Filled Cavity: A 12mm–16mm gap between panes disrupts sound
waves effectively. |
Asymmetrical Glass Thickness (e.g., 6mm + 8mm) further reduces
resonance. |
Acoustic Interlayers: Some systems use specialized films for
enhanced noise reduction. |
3. Airtight Seals & Gaskets | High-Quality Edge Seals: Prevent flanking noise leaks (critical for
achieving stated dB ratings). |
Compression Gaskets: Ensure a snug fit between glass and frame. |
Magnetic or Rubber Seals: Ideal for sliding doors to maintain
acoustic integrity. |
4. Decoupled or Staggered Wall Designs | Air Gaps in Double Walls: A 50mm–100mm cavity with insulation
(mineral wool, acoustic cotton) boosts low-frequency noise
blocking. |
Resilient Channels: Isolate the partition from building structures
to minimize vibration transfer. |
5. Frame Construction & Materials | Aluminum Frames: Opt for heavy-duty profiles (90mm–108mm) with
thermal breaks to reduce sound bridging. |
Rubberized Frame Inserts: Further dampen vibrations. |
6. Acoustic Performance Ratings | Target dB Reduction: 35–40dB: Standard offices (speech privacy). 45–50dB+: Meeting rooms, studios (confidential discussions). |
Certified Testing: Request lab-tested sound transmission class
(STC/Rw) ratings for accuracy. |
7. Aesthetic & Functional Integration | Frosted/Tinted Glass: Balances privacy with natural light. |
Smart Glass: Switchable opacity for dynamic spaces. |
Frame Finishes: Match corporate branding (e.g., matte black,
woodgrain). |
