Moisture impact on dimensional changes and air leakage in wooden buildings
Paper i proceeding, 2019
This project investigates the air leakages that occur in wooden buildings from seasonal variations in climate and from finished construction (first airtightness measurement) to equilibrium (when inbuilt moisture has dried out). Measurements are made in real buildings (full scale) and in laboratory (climate chamber). The full-scale measurements on buildings with wooden construction have shown magnitudes of up to 10% increase in air leakage (at 50 Pa) for the seasonal variations and the increase for reaching equilibrium in a newly built construction is 20%.
