Movable sound-proof partition walls are characterized by modular elements having high acoustic insulation up to an Rw index of 58 dB certified by an accredited laboratory. They are easily stored and slide quietly along guide rails fixed only into the ceiling. Designed to harmonize with the existing architectural style they can reach any length and up to 12 m. in height with covering in a choice of materials and finish. High-level technology guarantees quality and reliability while offering the ideal solution for a rapid, physical and acoustic division of areas destined to host large events, meetings, workshops, videoconferences and training sessions.
