What Is Air Tightness Testing?
Measuring uncontrolled air leakage
Air tightness testing measures how much air escapes from a building through gaps, joints, and unintended openings. The test identifies air leakage that can affect energy efficiency, comfort, and compliance with building regulations.
It is a key requirement for many new builds, extensions, and refurbishments, and plays an important role in reducing heat loss and improving overall building performance.
