Design and operation

The Espero Sonico consists of a number of individual sandwich panels that are suspended from and move along an overhead track. The panels are pushed together and interlock to form a wall. The panels are composed of a self-supporting aluminium frame reinforced with steel and high quality particle boards on both sides.

Acoustic integrity is achieved as follows: along the top and bottom of the panels by means of extendable pressure seals, along the vertical sides by acoustic rubber seals and internally with high performance sound absorbing materials. The sound insulation quality is further enhanced by a sound-break between the frame and outer boards. A telescopic end-panel enables the wall to be vertically locked into position completing the acoustic seal. The Sonico range is available with laboratory tested sound insulation values from Rw = 37dB to 53 dB.

The patented Espero Quick system ensures that the pressure seals are extended and retracted by a single 180° turn of a removable operating handle. Once retracted the panels can be moved effortlessly and quietly along the especially designed aluminium overhead track system. The track and carrier system provides ease of operation and flexibility allowing walls to be positioned or parked in countless configurations. The Sonico has been tested for sound reduction by internationally recognised test laboratories. In addition the Espero Sonico is TUV approved.

Options and possibilities

This brochure shows the Espero Sonico wall with single and double doors and walls with glass openings. Espero has completed many challenging and interested projects such as walls in excess of 12 metres height and walls with a special horizontal telescopic function to accommodate a snow bearing construction. If a design requirement falls outside of Espero´s comprehensive range and vast experience the R&D department will create the product to suit the client's specification.
