A well installed vapour barrier may also be required in some cold climates and/or high humidity buildings. Proctor Group Australia recommends that a condensation risk analysis is undertaken to determine if required.
There are a large number of factors that need to be considered in assessing and managing condensation risk. Such factors include the local climate, building use, position, thickness and type of insulation, position and integrity of vapour barriers, and the degree and location of mechanical or passive ventilation. It is highly recommended that designers undertake a condensation risk analysis.
