New building regulations to ensure safe use of combustible cladding


The WA Government has recently introduced building regulations to regulate the use of combustible material on building facades of high-risk buildings.

The new building regulations will stop the use of performance solutions by restricting the use of combustible cladding to those that can demonstrate compliance under the Building Code of Australia’s (BCA) new verification method. The method also includes the requirements for sprinklers in high-risk buildings.

The BCA has been updated early this year to omit any ambiguity around the use of combustible cladding in buildings.

“The McGowan Government is taking the issue of cladding very seriously,” said Acting Commerce and Industrial Relations Minister Francis Logan.

“Amendments to the building regulations have been introduced to close any opportunity for developers to get around the non-combustibility requirement for cladding in the BCA.”

Any combustible cladding being proposed to be used on buildings need to demonstrate it has passed the large-scale fire test required under Australian Standard AS 5113 or receive approval from the Building Commissioner.

The update to the BCA and introduction of new building regulations will prevent the use of dangerous polyethylene (PE) cladding or an expanded polystyrene cladding in a building façade.

“The changes will give Western Australians confidence and peace of mind that the cladding of the buildings they occupy is safe,” said Minister Logan.
