In busy city centres, near transport hubs, or in high-traffic areas, controlling external noise is essential for occupant comfort.

Key considerations:

• Noise attenuation – measured in R_w.
• Balanced design – combine acoustics with thermal and solar performance.
• Customised solutions – different areas of a façade may need different noise reduction levels.

Recommended glass types:

• Laminated acoustic glass with PVB or special sound-control interlayers
• IGUs combining laminated acoustic glass panes with insulated cavities
• Asymmetrical glazing thicknesses to dampen different sound frequencies
