What are the key considerations for bushfire-resistant construction standards for new homes in Australian BAL-29 zones?

For new homes in BAL-29 zones, key considerations for bushfire-resistant construction standards revolve around mitigating radiant heat flux. This involves specifying non-combustible or fire-resistant materials for external walls, roofs, windows, and subfloor areas. Gaps and openings must be effectively sealed to prevent ember entry. Window glazing requires toughened glass, and appropriate screening for vents and weep holes is essential. Additionally, ensuring compliant external attachments like decks and carports are designed to resist ember ignition and radiant heat exposure is critical for overall property protection and occupant safety.
