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.
