BAL Ratings Explained
How Stock Windows & Doors and CDK Screens Help Protect Your Home
Living in Australia means designing homes that can stand up to our harsh conditions — and for many, that includes the risk of bushfires. If your home is being built in a bushfire-prone area, you’ll need to meet BAL (Bushfire Attack Level) requirements. At Stock Windows & Doors, we partner with CDK Screens to ensure your windows and flyscreens not only look great but also help keep your home compliant and protected.
What is a BAL Rating?
BAL (Bushfire Attack Level) measures the severity of a building’s potential exposure to bushfire hazards such as ember attack, radiant heat, and flame contact. Ranging from BAL–Low to BAL–FZ (Flame Zone), your site’s rating is determined during an assessment and sets the standard for the types of windows, doors, and screens you’re required to use.
Why Windows Matter in Bushfire Compliance
Windows are one of the most vulnerable areas in a bushfire. Glass can shatter under heat, and frames can fail if not designed for higher BAL levels. That’s why we supply windows built for compliance:
– Durable aluminium frames — strong and low-maintenance.
– Toughened glass options — greater resistance to radiant heat.
– Customisation — we match the right style to your BAL rating without compromising on design.
The Role of CDK Screens
To meet BAL requirements, openable windows must be fitted with compliant screens — and that’s where CDK Screens come in:
– Made from stainless steel or aluminium mesh for strength and durability.
– 2mm aperture or less — preventing embers from entering your home.
– Modern finish — ensuring style without sacrificing safety.
– Everyday benefits — insect protection and improved airflow.
By combining our windows with CDK Screens, you get a solution that ensures compliance while enhancing comfort and functionality.
