Bushfires in Australia are almost a common occurrence during the hotter months due to Australia’s hot and dry climate. Bushfire events in New South Wales, South Australia, Canberra and Victoria have been the most tragic bushfire events to occur in Australia’s history.

The Alspec 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.
Our range has successfully exceeded the 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 to the building by occupants or fire authorities.
A range of window and door handles, including vent locks, security and fall prevention screens along with double glaze glass options for energy requirements or acoustic barriers are some of the additional features available to the complete Alspec BAL40 product range in catering for all requirements beyond bushfire.
All Alspec BAL40 windows are identified with a label to ensure the quality and compliance of the product to assist with certification onsite.
