❓ What Is Air Tightness Testing?
Air tightness testing (also known as air leakage testing or blower door testing) measures the uncontrolled flow of air through gaps and cracks in the fabric of a building. It’s a key component of ensuring energy efficiency and compliance with SAP Calculations and Part L regulations.
Buildings with poor air tightness lose up to 40% of heat, leading to increased energy bills and carbon emissions.
