Altair Louvre Windows in a Bushfire Prone Area

How to use Altair Louvres in the different Bushfire Attack Levels

The following requirements for using Altair Louvre Windows in bushfire prone areas are based on:

  • Our interpretation of AS 3959-2018 “Construction of Buildings in Bushfire Prone Areas”,
  • BAL-29 bushfire testing by the CSIRO of the Easyscreen Altair Louvre Window System with CrimSafe screens to AS1530.8.1-2007 (CSIRO Report number FSZ1572), and
  • A CSIRO Infrastructure Technologies report assessing alternative steel mesh screens (CSIRO Report number FCO-3026).

    (Warrington Fire Report number FRT200407), and
  • A Warrington Fire report assessing alternative steel mesh screens (Warrington Fire Report number FAS200470).

We recommend that you receive independent advice from both an engineer and your local council authority to determine your level of construction and to ensure that you comply with the correct protection measures for your individual circumstance.
