See below how Acoustic ceilings by Eurocoustic can contribute to BREEAM criteria: Acoustic performance .
Aim
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
Eurocoustic presents a wide range of products that combine acoustic absorption and lateral attenuation to improve the quality of listening and intelligibility of the exchanges inside the premises.
Eurocoustic ceilings are a suitable solution for the absorption of sounds, thus reducing the phenomenon of resonance.
The majority of our ceilings are class A, with a maximum absorption level. Hence, our ceilings contribute greatly to the control of the reverberation time.
