Glass Structure
8mm float + 12A + laminated glass (6mm float + 0.76mm acoustic PVB + 6mm float)
Features
Low-frequency noise reduction:
The 0.76mm acoustic PVB interlayer absorbs vibration through its damping properties, significantly reducing mid- to low-frequency noise from traffic, such as engine rumble and road noise.
High-frequency sound insulation:
The 12A air gap in the IGU effectively blocks high-frequency sound waves—such as conversation, speaker noise and other airborne sounds. Overall acoustic performance typically reaches 35–40 dB, outperforming standard IGUs that usually achieve around 25–30 dB (final values subject to lab testing).
Avoids the coincidence effect:
Laminated glass has a coincidence frequency around 3000 Hz, well above the typical traffic noise band (125–750 Hz), helping to eliminate resonance-based sound transmission.
Energy Efficiency & Thermal Comfort：
The low-conductivity air layer reduces heat transfer between indoors and outdoors, improving insulation performance and helping lower air-conditioning energy consumption.
Safety & Impact Protection
The PVB interlayer holds glass fragments in place if breakage occurs, preventing scattering and reducing injury risk. This meets safety requirements for high-rise and public buildings.
Applications
Residential:
Street-facing windows, bedrooms near arterial roads or elevated highways, and skylights or sunroom roofs.
Commercial:
Hotel façades facing busy streets, office buildings, hospitals and quiet rooms, and professional recording or audio rooms.
Special Environments:
Buildings near airports, rail-transit corridors, and acoustic barrier structures requiring enhanced noise control.
