Advise on Insect Screens In Bushfire Areas

Living in a Bushfire Prone area and working your way around the BAL (Bushfire Attack Level) building regulations can be a little daunting.

As soon as summer season hits, one of the most regular questions we get asked is “can you help me with screening my home? It’s in a bushfire zone”. The answer is often; “yes!”. However, it all comes comes back to 2 questions. What kind of opening or area are you screening? and what is the BAL of the area you live in?

So let’s simplify this whole BAL business.

BAL classifications are designed to improve building codes around properties in areas which are prone to bushfires. The higher the BAL number the higher the risk of ember and bushfre attack all the way up to BAL- FZ (Flame Zone) which is direct exposure to fames. Once you the BAL status for your area you can better assess your requirements. If you are unsure of the BAL for your area contact your local council and they will be able to give you details and advice you need.
