Airtightness of building envelope has become an important property of building envelope. The building envelope is locally sensitive to exfiltration airflow, as moisture convection could cause a remarkable increase in the moisture accumulation rate on the inner surface of the sheathing (Kalamees and Kurnitski, 2010). The objective of this research was to determine the effect of moisture dry-out from CLT panels and indoor humidity, as well as different insulation solutions and façade orientations to the air permeability properties of CLT external walls.
