Customer Story: Music Studio

Our customer, a drummer in a music group, has soundproofed his entire recording studio with the R'Acoustic 20. The result is indisputable: despite the power of the drums played at full force, absolutely no sound escapes outside the building.

construction

Quick installation on the ceiling

Watch an insulation professional fix R'Acoustic directly to a solid concrete ceiling using a compressed air nailer. The installer uses an ingenious adaptation on his plate lifter to easily roll out the insulation from his ladder. A simple and effective installation, ideal for blocking noise between two floors.
