What does BAL-FZ mean?
This is the highest danger rating that a property can be given regarding bushfires. It also means that the property is likely to be exposed directly to flames from the fire front and is susceptible to attack from embers. Additionally, a heat flux of more than 40kW/m2 can be expected.
Installing flame zone bushfire shutters is the only way to meet the BAL-FZ standards on a property with standard windows.
BAL ratings can vary from house to house and even vary depending on different sides of your home.
BAL ratings vary and are rated depending on the following criteria:
- Where you live
- The type and density of the vegetation around your home
- The distance from the vegetation to your home
- The slope of the ground beneath the vegetation
