Condensation and Water Vapour Control

On 1 May 2019, the National Construction Code introduced new requirements for condensation management in Class 1 buildings, Class 2 buildings and Class 4 parts of buildings where buildings must be designed to mitigate the risks associated with the amount of moisture that accumulates internally.

The new condensation management provisions aim to limit the amount of condensation that can accumulate within a building by requiring that water vapour be extracted to a point external to the building.

To prepare builders and designers, Council has prepared a document to advise of the new requirements as well as the relevant parts of Volumne 2 of BCA 2019 as well as some extracts from Australian Standards (AS4200.1 and AS4200.2).
