Key contribution

Saint-Gobain Glass offers a range of solutions, born of sustainable materials, that provide excellent levels of sound insulation by reducing external noise by up to 50 dB.


To provide workspace that promotes occupant’s well-being, productivity, and communication through effective acoustic design.

Detailed requirement

For all occupied spaces, the project has to meet specific requirements for:

  • Heating, ventilating and airconditioning (HVAC) background noise
  • Sound isolation
  • Reverberation time
  • Sound reinforcement and masking

Our contribution

For acoustic performance, we need to consider the glass-weighted noise reduction (Rw) that is the acoustic rating of the glazing. Saint-Gobain’s high-performance acoustic glazing can bring a lot of comfort by reducing this exterior noise by up to 50 dB (Rw).

To improve the acoustic performance of the glass, there are several options such as having:

  • Thicker glass to increase the acoustic performance;
  • Different thicknesses for the two panels of a double glazing unit; and
  • A single pane and a special laminated glass made of two sheets of glass bonded together with a plastic sheet specifically designed to enhance sound insulation.

The glazing solution has to be integrated into a good quality, airtight frame as noise can spread through any available air passage.
