How to Test for Combustible Cladding in Queensland

Sampling and Combustibility Testing

We can determine the chemical composition and indicative fire performance for any cladding materials used on a building’s external facade. This process involves identifying and collecting cladding material samples, followed by combustibility testing.

Test results are used to assess if the fire performance of the external facade will negatively impact the buildings fire strategy, and for making appropriate recommendations in the building fire safety risk assessment report.

Review As-Constructed Documentation

We review as-constructed drawings, manufacturer’s data sheets, facade specifications and fire engineering reports which may be available. These documents will provide a background of specified cladding products and insulation materials which will assist with on-site visual inspection and identification of possible product substitution.

Collect Cladding Material Samples

The external facades of modern buildings can have complex cladding systems which are generally constructed from numerous component parts. So prior to taking samples, buildings are visually surveyed to identify suitable locations for where selected cladding material samples will be collected.

Once sample locations are identified and agreed with building owners, work plans and risk assessments for the removal of samples are completed. Small core samples are then taken for the cladding surface panel, plus backing insulation and/or sarking material.

The required number of samples will be a factor of visual variations between panels, the extent of coverage, and if the building was constructed over different stages. This is defined by the building grouping assignment guide below:

Sampling work is carefully performed so that minimal damage is made to the surrounding facade, and the resultant core hole is plugged and sealed to maintain weatherproofing of the facade

Perform Testing and Analysis

We organise for cladding material samples to undergo testing in our state-of-the-art laboratory using advanced equipment and analytical techniques, and in alignment with how Government buildings are being tested. This is a relatively non-invasive and cost-effective process which involves a set of tests to identify the cladding materials chemical composition and to assess its thermal degradation.
