From PracticaMMC , MasterWall is the first external wall cladding system in Australia to demonstrate compliance with the performance requirements of the Building Code of Australia.

"When selecting an external wall cladding system it is important to ensure that appraisals and technical reports cover all relevant BCA Performance Requirements of the cladding system proposed to be used, and that the appraisal is current where it is being utilised to assist with the preparation of the alternative solution," says a spokesperson at PracticaMMC.

"Architects and Registered Building Practitioners, especially building designers, should take care in selecting and specifying polystyrene or other external wall cladding systems that they have at least been assessed by an appraisal body in order to assist the RBS in determining whether this form of construction is an acceptable alternative solution."
