FLAMEfixx dFx® achieves BAL-40 fire safety rating for treated pine

Back to news

In response to the devastating 2009 Black Saturday bushfires, the Australian Government introduced Bushfire Attack Levels (BAL). While the rating system strives to make homes more robust in the face of bushfires, it can present challenges for builders and homeowners alike. 

Budget blowouts, building materials compromises and changes to the desired style of the project are all common when building in high BAL-rated areas.  Up until recently, material choices for external enclosed substructures have been limited. For projects requiring BAL-29 and above ratings, the favoured choice of treated pine has not met conditions. 


That was until FLAMEfixx dFx®, the world’s first BAL-40 rated treated pine and a complete game-changer, came on the market. Extensively tested to meet the requirements of BAL-40, FLAMEfixx is impregnated with industry-leading dFx® technology that combines a globally approved, durable wood preservative and a proprietary fire-retardant. 

How it works 

When exposed to fire, FLAMEfixx dFx self-extinguishes the flame leaving a slightly blackened surface and the structural integrity of the timber intact.
