Why is airtightness in buildings important?
Airtightness is the measure of how much air leakage there is from a building. This is determined by carrying out an airtightness test and the figure obtained from the testing is the air permeability value. Airtightness is important for reducing heat loss, improving comfort and protecting a building.
