Bushfire

Capral bushfire-rated window and door systems are rigorously and comprehensively tested to meet and exceed relevant Australian standards up to BAL-40. They are fully backed by our technical and engineering support.

Many Australians choose to live amongst the beauty and tranquillity of our unique bushland; however, protecting buildings in bushfire-prone areas presents challenges in building and renovating. Homes today must meet the requirements of building regulations and standards, with Australian Standard AS3959 being updated and republished in response to devastating bushfires.

Construction of Buildings in Bushfire Prone Areas

Australian Standard AS 3959 specifies requirements for the construction of buildings in bushfire-prone areas to improve their resistance to bushfire attacks from burning embers, radiant heat, flame contact and combinations of the three attack forms.

The critical factors for building in bushfire-prone areas are improving the ability of buildings to withstand the initial fire attack better and hence providing the building occupants with a high level of protection.

Understanding Bushfire Attack Levels

Your bushfire risk level influences your development requirements; the higher the risk, the more protection you require. To measure this risk, the term ‘bush fire attack level,’ or BAL, is used.

BAL – LOW: Lowest risk from a potential fire.
BAL – 12.5: Risk is primarily from potential embers during a fire.
BAL – 19: Moderate risk, particularly from embers and burning debris.
BAL – 29: High risk, particularly from embers, debris and heat.
BAL – 40: Very high risk. Likely to be impacted by embers, debris, heat and potentially flames.
BAL – FZ: Extreme risk. Directly exposed to the flames of a potential firefront.

BAL-40 Windows, Doors & Framing Systems

Capral’s comprehensive range of window, door, framing systems and security screens have been developed and tested to meet and exceed NCC requirements for compliance under Australian Standard AS3959-2009 in areas rated up to BAL-40.

Capral products are engineered, tested and certified to withstand the conditions likely to occur in BAL-40 zones. They are designed to help you protect your home without compromising style, choice, efficiency and functionality.
