Cladding

Aluminium Cladding.

Aluminium cladding is a non-combustible exterior wall system used across residential facades, commercial buildings, and everything in between - valued for its durability, low maintenance, and design flexibility in the Australian climate. But Knotwood's aluminium cladding goes further than covering up. With crisp lines and architectural confidence, it adds texture, depth and a certain timelessness to any façade. Whether you're working on a bold commercial build or a refined residential project, it brings a level of design intent that's hard to ignore.

Lightweight yet tough against the elements, it offers the kind of low-maintenance durability that's as practical as it is good-looking. No warping, no rotting, no ongoing upkeep - just a façade that holds its look year after year. And with a range of profiles and finishes to choose from, Knotwood aluminium cladding can be tailored to suit almost any architectural vision.

FAQs

Why choose aluminium cladding?

Knotwood’s aluminium cladding is tough, weather-resistant and won’t rot or rust. It’s fire-safe, low-maintenance and built to last. Lightweight yet durable, it’s easy-to-install and available in a wide range of colours and finishes to suit any design.

Can I use Knotwood in C4-C5 coastal or industrial zones?

Yes. Knotwood aluminium cladding is suitable for coastal and industrial environments when installed with the correct fastener specification. Use 316 grade stainless steel fasteners in C4-C5 zones rather than 304 grade or hot-dip galvanised. The non-chromate pre-treatment and VOC-free powder coat finish provide additional protection against salt-laden air and industrial pollutants.

What lengths is Knotwood cladding available in?

Knotwood cladding is available in 6.5m and 5.65m lengths.

Can aluminium cladding be retrofitted?

Knotwood aluminium cladding can be installed over various existing materials, such as wood, brick or concrete, as long as the underlying structure is sound and properly prepared.

Can I use Knotwood in BAL-FZ (Flame Zone) areas?

Knotwood is non-combustible (AS 1530.1), but for BAL-FZ compliance, the whole wall system – cladding, framing, sarking, insulation, fixings and cavity barriers – must be tested or assessed together as BAL-FZ compliant.

Does aluminium cladding make a building hot inside?

No – aluminium actually reflects heat instead of absorbing it. When paired with the right insulation and ventilation, it helps keep indoor temperatures stable, even in hot climates.

How does Knotwood aluminium cladding compare to fibre cement cladding?

Knotwood aluminium cladding is non-combustible, 100% recyclable, and will not absorb moisture, crack, or require repainting. Fibre cement is heavier, requires periodic repainting, and can be vulnerable to moisture ingress at cut edges. Knotwood also offers sublimated timber grain finishes that fibre cement cannot replicate with the same depth of grain definition.

Is there an aluminium alternative to traditional timber weatherboard cladding in Australia?

Yes. Knotwood Tab-Lock Boards are designed specifically as a modern aluminium alternative to traditional weatherboard cladding. They replicate the horizontal weatherboard profile in a non-combustible, zero-maintenance aluminium system rated to BAL40, available in sublimated timber grain or solid powder coat finishes. No painting, sanding, or sealing is ever required.

Is Knotwood cladding compliant with the NCC for multi-storey or Type A and Type B construction?

Knotwood Interlocking Boards are tested to AS 4284:2008 for NCC weatherproofing requirements (FV1.1 and V2.2.1) and carry an AS 5637.1 Group One fire classification, supporting their use in Type A and Type B construction. Project-specific compliance assessment by a qualified building professional is required to confirm suitability for your specific building classification and location.

Is aluminium cladding a sustainable choice for an Australian building project?

Knotwood aluminium cladding is made from 100% recyclable aluminium with a non-chromate pre-treatment and VOC-free powder coat finish. Aluminium can be recycled repeatedly without loss of quality, and its long service life means no replacement waste from rot, warping, or fire damage. For projects targeting green building ratings, consult your certifier on aluminium’s embodied energy profile versus its lifecycle advantages.

Is Knotwood cladding suitable for use in a ventilated facade or rainscreen assembly?

Yes. Knotwood aluminium cladding profiles are well-suited to ventilated facade and rainscreen assemblies. The clip-fixed installation system creates a cavity between the cladding and the building envelope, allowing moisture drainage and air circulation behind the boards. This makes Knotwood appropriate for moisture-prone climates and high-rainfall Australian regions when installed over a compliant building membrane.
