BAL Flash

Bushfire Attack Level (BAL) assesses a building’s risk from ember attacks, radiant heat, and direct flame during a bushfire. Measured in kilowatts per square meter (kW/m²), these ratings are essential for ensuring structures in fire-prone areas can endure extreme conditions.

Three years ago, Aztec set out to create a BAL-rated roof kit for bushfire-prone areas. After extensive testing and improvements, we now offer a Roof Flashing System that meets requirements up to BAL 40, ensuring a secure, watertight roof in high-risk zones.
