You need to meet strict regulations when building in a bushfire-prone area. These regulations are in place to protect lives and property, and they leave little room for error. Choosing the right cladding in a bushfire zone is critical as it must meet compliance rules, support insurance eligibility, withstand extreme heat, and provide a measurable return on investment (ROI) over time.
Timber cladding is a common choice for its appearance; however, it cannot meet the requirements in high-risk zones. Fortunately, aluminium cladding does. It’s a non-combustible alternative, approved for the highest Bushfire Attack Level (BAL) ratings, and often preferred by insurers. Plus, timber-look aluminium cladding variants give you the best of both worlds, keeping your build compliant without sacrificing aesthetics.
Contact us to talk about how aluminium cladding can support your project in a BAL-rated zone. If you’re still not sure if aluminium cladding is the right choice for your project, there are two key reasons why you should consider this as an alternative:
- Timber is not suitable for high-risk bushfire areas
Australia uses BAL ratings to assess the risk of fire exposure on buildings. Higher BAL ratings indicate greater fire risk and, in BAL-40 and BAL-FZ zones, external walls must be built with non-combustible materials. This is a legal requirement under AS 3959:2018 and enforced through the National Construction Code (NCC).
Timber is a combustible material, and even treated timber does not pass the fire-resistance tests required for BAL-40 and BAL-FZ zones. Using timber cladding in these zones would fail compliance checks and could prevent your build from being approved.
AliWood’s aluminium cladding is non-combustible, passes all required tests, and is approved for use in all BAL zones, including the highest risk level, BAL-FZ.
- Insurers consider your materials when setting premiums
The Insurance Council of Australia has stated that combustible cladding increases the risk of fire and raises insurance premiums. Buildings clad in timber may face higher premiums or even be denied coverage in bushfire zones.
Aluminium, by contrast, is a solid, non-combustible material. Using aluminium cladding can reduce your fire risk rating and make it easier to get insurance. It also helps you secure more competitive premiums and broader policy coverage.
This makes aluminium more than a compliant option; it’s also a smarter investment.
Making a smarter choice with aluminium cladding
Choosing cladding is about more than meeting code; it’s about delivering a project that is fire-safe, insurable, visually appealing, and built to last. Aluminium cladding offers distinct advantages that make it a practical choice for bushfire-prone areas. There are five ways it delivers more value at every stage of the build and beyond:
- Simpler compliance and faster approvals
AliWood’s aluminium cladding supports faster design approval and smoother handovers. It meets AS 1530.1 and AS 1530.3 requirements for combustibility and fire spread, complies with AS 3959:2018 and the NCC, and is approved for use in BAL-40 and BAL-FZ zones. This gives councils and certifiers greater confidence, reduces the risk of design changes or delays, and keeps your project moving forward with clear, complete documentation.

- Fire performance you can prove
Aluminium cladding has passed the AS 1530.1 non-combustibility test and the AS 1530.3 fire hazard properties test. That means it doesn’t ignite, burn, or produce significant smoke or heat when exposed to fire. This level of performance slows the spread of flames in real bushfire scenarios and protects the building structure long enough for safe evacuation and emergency response, delivering measurable, life-saving benefits.
- A realistic timber alternative
Timber-look aluminium cladding replicates the appearance of natural wood without the fire risk, warping, or rot, and its powder-coated finish resists fading without the need for repainting or resealing. This lets architects achieve a warm, textured look that complies with BAL-FZ requirements, removing the need to compromise between design intent and safety regulations.
- Lower lifetime insurance costs
Using aluminium cladding can help you reduce your insurance premium at the outset; however, the real value comes over time. Non-combustible materials like aluminium can reduce policy exclusions, increase claim eligibility, simplify renewals, and result in reduced financial risk and thousands of dollars saved over the building’s lifespan.
- Better performance in extreme environments
Australia’s climate can be brutal, though aluminium cladding won’t crack in the heat, swell in the rain, or attract termites. It’s also highly resistant to corrosion, especially when powder-coated or anodised. This reduces the need for ongoing repairs, replacements, or inspections, especially in rural and coastal areas where weather exposure and pests are common.
Achieving better outcomes long after the build
Building in a bushfire zone comes with strict regulations, insurance challenges, and limits on using materials like timber. Choosing a compliant, high-performing option such as aluminium cladding helps meet approval requirements, supports insurance eligibility, and provides a durable solution that withstands harsh conditions. It also delivers long-term value through lower insurance premiums, fewer maintenance requirements, and reduced risk of costly delays or redesigns. Over time, these benefits contribute to a stronger ROI, whether you’re building to own, sell, or lease.
AliWood’s timber-look aluminium cladding system delivers the natural look of timber with the strength and fire safety of aluminium. It resists rot, mould, and pests; stays low-maintenance; and meets non-combustible requirements for lasting performance. The lightweight panels come in a range of realistic wood-look finishes and profiles and are installed easily with concealed fixings for a clean, modern finish.
