Our honest verdict
Choose timber if you want real wood that silvers and patinas and you will commit to oiling it. Choose woodgrain aluminium if you want that look to stay put with almost no upkeep, or you are building on bushfire-prone land.
The honest case for timber
Real timber has depth that no print fully matches up close, and it ages with character. If you actively want a facade that weathers and silvers, a species like blackbutt or spotted gum delivers that in a way aluminium cannot - aluminium holds the day-one look and will not change.
Timber is also a renewable material with a low embodied-energy story when sourced responsibly, which matters on some projects.
Where aluminium pulls ahead
Maintenance is the big one. Oiled or stained timber cladding needs recoating roughly every one to three years depending on aspect and exposure, plus repairs to cupped or split boards. Woodgrain aluminium needs an occasional wash and nothing else.
Aluminium is non-combustible to AS 1530.1, so it is viable on bushfire-prone land and on buildings where the NCC restricts combustible external walls - situations where many timbers are ruled out or heavily detailed.
It is dimensionally stable too: it will not swell, cup or pull off fixings through wet-dry cycles, which is why it suits humid and coastal sites better than solid wood.
The trade-offs to weigh
Aluminium is a fixed look - if patina is the point, it is the wrong product. Up extremely close, a trained eye can tell a sublimated grain from real wood. And there is no re-sanding back to bare material; a damaged board is replaced rather than refinished.
The two contenders
Woodgrain aluminium
Solid marine-grade aluminium with a sublimated woodgrain coat. Non-combustible substrate, holds its day-one colour, and needs only an occasional wash - no oiling, no recoating.
Natural timber
The look is close; the lifecycle is not. Here is where each material genuinely wins.
At a glance
Side by side on the points that decide most projects.
| Factor | Woodgrain aluminium | Natural timber |
|---|---|---|
| Combustibility | Non-combustible substrate (AS 1530.1) | Combustible; restricted on BAL-rated land |
| Maintenance | Occasional wash | Oil/stain every 1-3 years |
| Stability | Will not cup, swell or split | Moves with moisture and heat |
| Ageing | Holds day-one colour | Silvers and patinas over time |
| Repairs | Replace the board | Sand and recoat |
| Coastal | Marine-grade alloy suits salt air | Greys and weathers fast by the sea |
The Woodonali product
Architectural cladding that reads as natural timber but is engineered from non-combustible aluminium - the warmth of a hardwood facade without the rot, the repainting or the bushfire worry.
