Flamezone Stainless steel BAL FZ roller shutters have been in production since 2019. The need for Bushfire resistant Bal FZ roller shutter has been increasingly growing in Australia’s harsh climate & hill faces. Bushfires have been widespread and are a regular occurrence that have contributed significantly to shaping the nature of the continent over millions of years. New builds and renovations in bush fire prone areas are required to comply with the new BAL ratings. A certifier will usually be required to sign off and give the building final approval prior to occupation. It is strongly recommended for BAL 40 and BAL FZ roller shutter to discuss options with us prior to commencement of building.
Flamezone stainless steel Bal FZ roller shutters Bal FZ. BAL FZ Rating – Flame zone bushfire BALFZ-82 shutter are tested and proven with a standard window to comply with AS3959-2009 and AS1530.8.2 (2018) by CSIRO in 2019. Manufactured here in Australia. The FZ bushfire shutters are made from highly durable, roll formed Stainless Steel interlocking slats, which shield windows from embers and debris that are thrown from a bushfire front.
Bushfire Attack Level or BAL is a method for rating the intensity of a locations potential exposure to bushfire. Identifying the Bushfire Attack Level around your property can help you site a new structure or better manage an existing one.
BAL assessment – Bushfire best practice guide (csiro.au) is the link for the csiro that explains this in full.
While important, BAL (calculated using any method) should be thought of as a relative estimate of the potential exposure on your property, rather than a precise measurement. It’s important to understand that for development in the Bushfire Management Overlay (BMO) your council’s Planning Scheme in many instance will set minimum requirements for you BAL and defendable space which will need to be incorporated into you planning permit application.
| BAL-40 | 29 – 40 | Increasing levels of ember attack, burning debris and radiant heat up to a level of 40 kW/m2. Flames from the bushfire front may intermittently contact the house. |
| BAL-FZ | ≥ 40 | Increasing levels of ember attack, burning debris and radiant heat in excess of 40 kW/m2. Flames from the bushfire front are likely to engulf part or all of the house. |
