[Current]Exterior insulation and finish cladding systems
AS 5346:2023 specifies the requirements for exterior insulation and finish systems (EIFS) as an exterior wall cladding system either in combination with a drained air space or directly fixed to a structural supporting element. It also specifies the requirements for water resistive barrier systems that are to be used with EIFS.
