The key to acoustics is determining what your needs are. A sound rating should be chosen to suit the surrounding structure, the sizes of the partitioned areas and use of the space.
At Lotus, we conduct extensive research and testing of our full systems (not just our panels) to ensure that we manufacture walls that are BCA compliant and meet Australian Standard 1191-2002 for acoustical requirements.
See Opera brochure pages 4-5 for a detailed overview of acoustics.

A simple straight track. Each panel is suspended from the central trolley and typically hinged pairs.
Single panels are suspended from two carriers at the top corners of each panel. Panels stack with one carrier remaining on the main track and the other in the side track.
Panels have omni-directional carriers to negotiate L or T junctions and panels are stacked completely away from the main track, sometimes in a cupboard or recessed stacking bay.
An Opera acoustic glass operable wall needs a method of acoustically opening and closing the system. Interlocking panel edges mean that a gap needs to be created along the track to break and stack the panels. This can be achieved using the options below.
Solid expanding panel (not glass) – This panel is an over-sleeve that can be expanded sideways to lock the wall in place. This is operated by a removable handle in the face of the panel.
Suitable for most applications (3m high max). The last panel is a full height door hinges off the fixed jamb or the prior panel. Doors are normally located at one of the panel with typical width 900mm.
Seals are used at the top and bottom of panels to ensure an acoustic fit with the overhead track and the floor.
Two seal combinations can be used:

Lotus Opera Switch takes flexibility to a whole new level. At the push of a button the Opera Switch Wall is clear to allow maximum light transfer then transforms to opaque to ensure privacy when required. The glass can be customised by applying your own film coatings, signage, graphics, decals and digital prints after install.
