Cladding: Fire Safety and Remediation

About this course.

Combustible external wall cladding has become a significant safety issue because certain cladding products, when used on the outside of a building, can catch fire and help a fire spread rapidly up the external face of the building — bypassing many of the internal fire-safety measures that a building relies on. A fire that starts in one apartment or on a balcony would normally be contained for a time by internal walls, floors and compartmentation, giving occupants time to escape and firefighters time to respond. Where a combustible cladding system is present, a fire can instead run up the outside of the building and re-enter at higher levels, defeating that containment. This external fire-spread pathway, and the risk it poses to life safety in taller and higher-occupancy buildings, is the heart of the concern.

The issue rose to prominence internationally and in Australia after a number of high-profile fires involving external cladding demonstrated how quickly fire can travel up an affected façade. This course does not describe any specific fire — it does not name buildings, give dates, or state casualty figures, because inventing or mis-stating such details would be inappropriate and unnecessary. The general point that matters for practitioners is simply that real-world fires showed the external fire-spread risk to be genuine rather than theoretical, and that this evidence prompted governments, regulators and the building industry across Australia to treat combustible cladding as a serious, systemic problem requiring investigation and, in many cases, rectification.
