A fair question after the cladding fires. Here is the honest, precise answer about substrate, systems and compliance.
The substrate is non-combustible
Solid aluminium is non-combustible to AS 1530.1. Unlike polyethylene-cored composite panel, there is no combustible core - it is solid metal with a baked finish.
But compliance is system-wide
Honesty matters here: a building's external-wall compliance is assessed on the complete wall build-up, not one product. A non-combustible substrate is a strong starting point, not a blanket guarantee for every wall it goes into.
