Air leakage is the uncontrolled movement of air through the unintentional cracks and gaps in the roof, walls and floor of a building. Air tightness testing enables you to do three important things:
1. Quantify air leakage by scoring a building and enabling comparisons to national and international benchmarks
2. Provide important qualitative information about air leakage pathways within a building and
3. Inform your ventilation strategy and mitigate mould and condensation risks.
