When Silence Is a Spec—And a Selling Point
Acoustic performance isn’t just an architectural concern. In industrial environments—labs, manufacturing cleanrooms, medical facilities, transportation cabins—sound control is a critical function of glass and ceramic materials.
Key Acoustic Metrics
STC (Sound Transmission Class): How well a material blocks airborne sound.
OITC (Outdoor-Indoor Transmission Class): Measures lower-frequency sounds like traffic or HVAC systems.
Damping Capacity: How well the material dissipates vibration.
Material Performance Ranges
Laminated glass: Top performer for sound isolation, especially with PVB or acoustic interlayers.
Thicker monolithic glass: Improved mass, moderate improvement in STC.
Ceramic-glass panels: Useful in high-durability, moderate-STC applications (e.g., correctional or lab settings).
Applications Where This Matters
Server rooms and cleanrooms (prevent vibration interference).
Hospitals and clinics (patient comfort and confidentiality).
Transportation and aerospace (engine and vibration noise).
Procurement Strategy
Ask vendors for tested STC/OITC ratings—don’t assume based on thickness alone.
Evaluate multi-layer vs. single-layer systems.
Balance acoustic benefit with fire rating, impact resistance, and weight.
Conclusion
Acoustic performance is a high-value property that’s often overlooked in early specs. Buyers who integrate sound control into sourcing can help clients meet performance benchmarks—and win complex contracts.
