Due to Australia’s hot and dry climate bushfires can be a common occurrence.
Bushfire Attack Levels:
BAL – LOW: There is insufficient risk to warrant specific construction requirements
BAL – 12.5: Ember attack
BAL – 19: Increasing levels of ember attack and burning debris ignited by windborne embers together with increasing heat flux between 12.5 and 19 kW m2
BAL – 29: Increasing levels of ember attack and burning debris ignited by windborne embers together with increasing heat flux between 19 and 29 kW m2
BAL – 40: Increasing levels of ember attack and burning debris ignited by windborne embers together with increasing heat flux with the increased likelihood of exposure to flames
BAL – FZ: Direct exposure to flames from fire front in addition to heat flux and ember attack
The Glass Co Metro BAL40 aluminium range has been designed to withstand temperatures of up to 40kW without failure to the glazing system while complying with AS2047. Protection from ember attack and burning debris preventing internal ignition to the building prevents possible loss of homes from the start.
The BAL40 range successfully exceeded system test requirements outlined in AS1530.8.1 while remaining in operation after the test. Although there are no requirements set for operation after a test, having peace of mind in functioning allows for potential egress and access of the building by occupants or fire authorities. These results are possible through the extensive Research & Development adding to the high quality design and functionality of this product.
