Operable wall shall be Bildspec Series 100/ Series 100R.  Note: The manufacturer shall guarantee that the operable walls are of like construction to those laboratory tested to AS 1276 by an independent Australian Acoustic Laboratory. installed by an authorized representative of the manufacturer and shall consist of top supported, manually operated panels that can be linked together to form a sound retardant closure.

Panels shall be 100mm thick and constructed with two outer skins of particle board or MDF board, separated by appropriate acoustic insulation contained in an extruded aluminium perimeter frame with interlocking vertical stiles. Panel faces shall be replaceable in the field.

Series 100 - acoustic seals at track and floor shall be dual, triple finger extruded vinyl. 

Series 100R - acoustic seals at track shall be dual, triple finger extruded vinyl and at floor shall be mechanically operated retractable type. Variations in the retractable top and bottom seals are available on request.

There are three main configurations by which operable wall panels can stack to the side of the opening: 

Centre Stack: Every panel hangs from a central trolley and typically hinged in pairs, perpendicular to and through the centre of a single overhead track. 

Side Stack: Panels are hung from two carriers at the top end of each panel. When stacking, one carrier stays on the main track and the other in the side track. 

Remote Stack: Panels have Omni-directional carriers to negotiate L or T junctions and panels are stacked entirely away from the main track.

One or two point according to stacking system required operating in extruded aluminium track. 

Bildspec, in conjunction with a testing lab, performed a variety of pull tests on their complete systems to ascertain the maximum failure load of their track and trolley systems when installed. 

Using a 200kN testing machine, we loaded the systems up at 5mm/min to produce analytical graphs for our consulting engineers to calculate the SWL for our complete installed system. 

The engineers calculated the SWL using factors of safety and in conjunction with AS/NZS 1170.0 - 2002/ Amdt 2011 Structural Design Actions - Part: 0 general principles, and AS/NZS 1170.1 - 2002/ Amdt 2011 Structural Design Actions - Part: 1, permanent, imposed, and other actions. 

Bildspec completed this certification to make sure our systems were fit for purpose and will perform correctly every day of the year. 

There are two methods by which an operable wall can be opened and closed, while still accommodating for the wall's acoustic properties. 

1. An Expanding Panel is expanded sideways to lock the wall in place via a removable handle at the stacking end of the wall.
2. Door Panels can be used on walls up to 3000mm high. The last panel (end of the wall) can be hinged off the end jamb or second to last panel. Standard width is 900mm.

Bildspec 100 Series Operable Walls have been tested for their acoustic performance at CSIRO’s acoustic testing facilities in Clayton, Victoria. We can provide walls that are rated 45Rw, 47Rw, 49Rw, and 52Rw, in accordance to AS1191.
