The Espero Sonico consists of individual panels that are suspended from, and slide along, an overhead track. The panels can be pushed together and can interlock to form a wall. The panels are held by a self-supporting aluminium frame reinforced with steel and high-quality particle boards on both sides.

Acoustic integrity is achieved by the use of extendable pressure seals running along the top and bottom of the panels as well as with acoustic rubber seals running along the vertical sides and high-performance sound-absorbent materials that are used internally. The quality of the acoustic insulation is further enhanced by a sound-break between the frame and outer boards. A telescopic end-panel enables the wall to be locked vertically into position, completing the acoustic seal. The Sonico range is available with laboratory tested acoustic insulation with values from Rw = 37dB to 58 dB.

The patented Espero Quick system ensures that the pressure seals are extended and retracted with a single 90°-turn by using a removable operating handle. Once retracted, the panels can be moved effortlessly and quietly along the especially designed aluminium overhead track system. The flexible track-and-carrier system is easy to operate and allows walls to be positioned or parked in countless configurations. The Espero Sonico has been tested for sound reduction by internationally recognised test laboratories and has been awarded TUV Approval.
