Hebel AAC (autoclaved aerated concrete)
Hebel autoclaved aerated concrete (AAC) is renowned for its fire resistant properties and is a non-combustible building material. As a result, all Hebel cladding and blocks meet or exceed the requirements for all six Bushfire Attack Level (BAL) categories, making them a logical choice when building in a bushfire zone.

Bushfire zone requirements
It also provides construction and building material provisions for the use in buildings to resist bushfire attacks resulting from burning embers, radiant heat, flame contact and combinations of the three.
A building certifier or surveyor will use the designated BAL rating to check compliance with the construction requirements of the standard and / or any other local legislative requirements. It is the responsibility of the building designer to ensure compliance to AS 3959 and / or any other local legislative requirements are met in accordance with the requirements of the National Construction Code (NCC) 2022.
