Key contribution

Saint-Gobain Glass offers solutions, born of sustainable materials, with excellent levels of sound insulation without the need for heavy glass. Thanks to our acoustic glazing, external noise can be reduced by up to 50 dB.


To ensure the building's acoustic performance, including sound insulation meets the appropriate standards for its purpose.

Requirement summary

All unoccupied spaces must comply with defined indoor ambient noise level (either national regulation, or good practice standards, or BREEAM levels). The ambient noise is measured on site by a suitably qualified acoustician to ensure that the relevant spaces achieve the required levels. The sound insulation between “acoustically sensitive rooms” (offices, meeting rooms, rooms used for public speaking or seminars …) and other occupied areas comply with the privacy index.

For rooms/areas used for speech, a reverberation time level has to be respected

Our contribution

The acoustic performance of glazing is defined by the Rw value, meaning weighted noise reduction. Noise pollution is a serious issue and Saint-Gobain’s high-performance acoustic glazing for facades and windows can create a lot of comfort by reducing this exterior noise by up to 50 dB (Rw).

To optimize acoustic performance, there are several options, such as having: 

  • Thicker glass to increase 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. 

Here is our selection of glazing to reduce surrounding noise:

Acoustic performance

Since noise can spread through any available air passage, this strong acoustic performance relies on a good quality integration into an airtight frame.
