Air tightness is often shown as m³/h/m², but what does that figure actually tell you about a building? Our plain-English guide explains how the measurement is calculated, what the result means for Building Regulations, and why a lower figure generally indicates a more airtight, energy-efficient home. Understanding the result can help you spot issues early, avoid costly delays and make informed decisions when a property fails its air test.
