The aim of the vapour control layer is to control where water vapour travels within the building and to try to minimise the risk of condensation occurring within the building or within the interstitial spaces of building elements. The session will cover: fundamentals of humidity and water vapour; vapour permeability of materials; ventilation within the […]

The aim of Air control in a building in a cool climate is primarily to control heat loss through unwanted infiltration of outside air. This session will cover; building sealing strategies; air control membranes; air leakage standards and testing; and the importance of introduced mechanical ventilation in well-sealed buildings.
