Combustible Cladding Investigation & Reports

What is Aluminium Composite Cladding and Expanded Polystyrene?

  • Aluminium Composite Panels (ACP) are a lightweight material primarily used as a cladding for buildings and in signage. 
  • Each panel is made up of an inner and outer aluminium sheet and a plastic or mineral core.
  • Polyethylene and Polyurethane are frequently used for the panel core and each can be highly combustible if not treated correctly.
  • The panels can be used as a decorative application, often spanning multiple floors in medium and high-rise buildings. 

  • Expanded Polystyrene (EPS) is a lightweight construction method where Polystyrene is attached to a framework and the EPS is then rendered.

  • EPS burns readily, is hard to extinguisher and produces a noxious smoke.

Which Codes Affect Aluminium Composite Cladding?

The Building Code of Australia (BCA) requires that all materials used in the construction industry meet certain minimum safety standards. The use of ACP or EPS as an external wall cladding may not meet the BCA requirements.

There is a potential fire risk where ACP or EPS is used extensively in a building. That risk is increased where it is exposed to an ignition source, where it spans several floors or where it is used in balconies.

Combustible Cladding Investigation Report


AESG has developed a staged Combustible Cladding investigation methodology designed to identify potential problems with a building and then to gather enough information that can be used in an expert Fire Engineering report.

Each investigation begins with a screening assessment that determines if any potential ACP or EPS is present on the building. In many cases the investigation stops at this point and the report states that no problem is apparent. Where a potential problem exists, AESG will pursue plans if they are available or conduct a series of more detailed inspections and tests.

Our final report will cover all the details that can be used to definitively determine a building's cladding risk.
