Why Acoustic Performance Matters

In today’s high-density urban environments, unwanted noise from traffic, construction, and city life can disrupt sleep, productivity, and well-being. Hospitals, schools, hotels, and luxury residences demand higher acoustic comfort to support healing, focus, and privacy. Our advanced window systems offer real sound protection.

Multi-Layer Insulated Glass (IGU)

  • Dual or triple IGU structures scatter sound waves.
  • Finite Element Analysis (FEM) ensures durability under wind pressure and impact.
  • Configurable thickness options: 6+12A+6mm, 6+12A+4+12A+6mm.
  • Achieves Rw values of 38–45 dB in lab tests.

PVB Laminated Acoustic Glass

  • Sandwiches PVB film for high mid-frequency sound absorption.
  • Especially effective for voices, music, and traffic sounds.
  • Thickness options: 6.38mm, 8.76mm, 10.76mm.
  • Bonus: Shatter-resistance and UV protection.
Customize your acoustic glass

Sound-Resistant Profile System

  • Multi-chamber aluminum profile reduces resonance.
  • Paired with EPDM or foam seals for leak-proof design.
  • ≤0.5 mm air gaps stop sound leakage.
  • Thermal break design adds insulation benefits.

Multi-Layer Sealing System

  • Triple or quadruple seals: foam + wool + hard rubber.
  • Each seal targets a specific frequency band.
  • Closed frame creates “quiet chamber” inside.
  • STC ratings up to 45.
Build your quiet space

Certified Acoustic Performance

  • Tested by independent acoustic labs.
  • Complies with EN ISO 10140, EN ISO 717, GB/T 8485.
  • Rw/STC data available for projects.
  • On-site mockup and lab results available.
