Alucobond panels complied with all relevant laws and codes and it was only the decisions of consultants and contractors that resulted in them being used in ways that were dangerous and created risk of fire, the country's largest supplier of polyethylene-core panels says in its defence to a potentially devastating class action claim.

The 100 per cent PE-core aluminium composite cladding sheets "were capable of being used or fitted onto buildings by qualified professionals" in ways that met state and territory requirements as well as the National Construction Code, Sydney-based Halifax Vogel Group said in defence documents filed with the Federal Court.
