General
Hollow walls up to 3 metres high x 12
metres long and thicknesses of 120mm and 150mm are produced.
These are cut to specific height and length with door and window
openings. |
| |
|
|
| |
 |
Structural
Walls are concrete filled with a minimum
32 MPa to achieve acoustic, structural and fire performance.
Walls are designed using the unreinforced concrete design provisions
of AS3600 section 11.4. |

|
|
| |
 |
Fire
Concrete filled load bearing 120mm Ozwall
achieves a minimum FRL of 120/120/120. |
| |
|
|
| |
 |
Acoustic
Concrete filled 120mm/150mm Ozwall achieves
an STC of 45. BCA compliance is achieved by the addition of
a plasterboard lining system to one side only. |
| |
|
|
| |
 |
Services
Electrical conduits are placed within
the cavities prior to concrete filling. Plumbing is hidden within
localised linings attached to the Ozwall. |

 |
Construction
Ozwall pre-cut walls offer most of the
benefits of concrete pre-cast but without the weight and craneage
requirements. A typical Ozwall wall weighs less than 700kilos
and is easily craned into place. Typically, 200m2 of wall installation
in a day is easily achieved with a small erection crew. |
