Living in Australia offers a lifestyle beyond compare. But the threat of bushfires is never far from your doorstep and needs to be considered when building or renovating. Australian Standards outline different construction practices and building materials for five bushfire hazard levels, known as Bushfire Attack Levels (BALs).
> BAL 12.5: Low
> BAL 19: Moderate
> BAL 29: High
> BAL 40: Very high
> BAL FZ: Flame zone
Stegbar aluminium double hung windows can be constructed to meet a rating of up to BAL 40. To determine your home’s BAL rating, and any special requirements for building in your area, consult your local council, government, or local fire authority.
