Be aware of the changes when building in a bushfire prone area
After the Royal Commission into the 2009 Victoria Black Saturday bushfires, the Australian Standard AS3959-2009 Construction of Buildings in Bushfire Prone Areas was updated. Research showed over 85% of homes burn down due to ember attack during a bushfire. This is where houses ignite and burn due to wind borne embers as opposed to direct flame contact by the bushfire front.
The Standard is primarily concerned with improving the ability of buildings in designated bushfire-prone areas to better withstand attack from bushfire.
In 2011 an amendment (AS3959-2009/Amdt2011) was made specific to ember guards. It requires that any gaps around the house greater than 3mm need to be sealed; an option is a mesh or perforated sheet with a maximum aperture of 2mm.
An ember guard is not specifically designed to act as a gutter guard, but Blue Mountain Mesh 2mm Super Fine Gutter Mesh is not only a high quality steel gutter guard custom-made in COLORBOND® colours to suit any roof type, but also meets the Standard to act as an ember guard for gutters.
Blue Mountain Mesh 2mm ember guard
Blue Mountain 2mm Superfine All Steel Mesh has been specifically designed to meet the Australian Standard for the ember guard protection of sheet roofs for all Bushfire Attack Levels (BAL-12.5 clause 5.6.3; BAL-19 clause 6.6.3; BAL-29 clause 7.6.3; BAL-40 clause 8.6.3; BAL-FZ clause 9.6.3-2011); and the product has also undergone rigorous, independent testing by the CSIRO to certify that the materials used meet the definition of non-combustible prescribed in the Building Code of Australia.
