A Guide to Window and Door Design and Compliance in Bushfire Prone Areas

Australia’s bushfire-prone environment presents unique challenges for building design, particularly when it comes to windows and doors. These elements play a critical role in protecting structures from ember attack, radiant heat, and direct flame exposure. Compliance with bushfire construction standards is not just a regulatory requirement—it is essential for enhancing resilience and safeguarding lives and property.

Building on this, we’ll take a closer look at the specific requirements outlined in AS 3959:2018 – Construction of Buildings in Bushfire-Prone Areas, including how Bushfire Attack Levels influence material selection and design choices. From fire-resistant glazing solutions to ember-proof seals, we’ll explore the key components that enhance protection against bushfire threats.

Learning objectives 

At the end of this presentation, you should be able to:

• Explain how buildings come under attack in a bushfire.
• Provide an overview of AS 3959 and its role in the design and construction of buildings in bushfire-prone areas. 
• Explain how Bushfire Attack Level (BAL) is determined under the relevant Australian Standard (AS 3959).
• Describe how different BALs affect the specification of windows and door systems including the requirements for compliant design.
