What is Aerosol Duct Sealing?

A sealing method in which the system is pressurised and an aerosolised sealant is introduced, depositing at leak edges until they close. It reaches leaks behind drywall and buried in insulation that no one can physically access. It is measured — the system is pressure-tested before and after — so the result is a number rather than an assurance.
