ACOUSTIC GLASS UNITS

The acoustic insulation of insulating glass units depends primarily on their layered structure and the types of glass used. Effective sound reduction is achieved through:

• the use of laminated glass with acoustic PVB interlayers,
• increasing the mass of the glass, which improves attenuation of low-frequency sounds,
• asymmetrical construction, where the panes differ in thickness.

Each of these solutions helps reduce different types of noise—from high-frequency street noise to low-frequency sounds generated by aircraft take-off or passing trains.

In practice, acoustic glass is indispensable in buildings located in city centers, near busy roads, or close to airports. A properly selected sound-insulating glass unit not only enhances occupant comfort but also positively affects health and well-being. Sound-absorbing glazing also reduces reverberation inside rooms, providing quiet, comfort, and a sense of privacy.

Acoustic glass is a key—though not the only—component of effective sound insulation. The final acoustic performance of a window system is also influenced by:

• the type and construction of the window frame,
• the quality of the fittings,
• the installation method.

For this reason, choosing the right sound-insulating glass should be based on an analysis of the specific case, taking into account the noise characteristics and project requirements. Our technical team supports clients already at the design stage, offering configurations tailored not only to acoustic parameters but also to additional needs such as thermal insulation, safety, or solar control.

Vitroterm-Murów supplies sound-absorbing glass for residential, office, hotel, educational, and industrial applications—always with full documentation and technical support.

Acoustic glazing is used in modern residential construction as well as in office, hotel, and medical environments. It is an investment in comfort, health, and quiet living. Acoustic glass effectively reduces noise while combining functionality with modern design. It transforms any room into a peaceful, quiet space—regardless of external noise levels.

Vitroterm-Murów acoustic glass provides high levels of sound insulation, measured in accordance with the European standard EN 12354.

Noise Reduction Indicators:

• Rw [dB] – the basic index of airborne sound insulation.
• Rw + C [dB] – correction factor for medium- and high-frequency noise, such as speech or office sounds.
• Rw + Ctr [dB] – correction factor for low-frequency noise, e.g., road traffic or aircraft noise.

Acoustic Performance Range for Vitroterm-Murów Glass:
Rw = 28 to 53 dB – depending on the configuration of the glass unit.

Solutions Compliant with U.S. Standards:

For projects requiring American standards, we also offer glass with the following ratings:

• STC (Sound Transmission Class) – indicates the effectiveness of reducing typical indoor sounds, such as conversations or office equipment.
• OITC (Outdoor-Indoor Transmission Class) – considers low-frequency external noise, such as urban transportation.
