What is Aeroseal?

Patented Technology

A Breakthrough in Ductwork Sealing Technology

Aeroseal’s innovative aerosol duct sealing technology was invented in 1994 by researchers at the Energy Performance of Buildings Group at the University of California’s Lawrence Berkeley National Laboratory.

The technology works to internally seal leaks in ductworks by injecting an aerosolized fog of sealant particles into a pre-pressurized duct system. The particles remain suspended inside of a moving air stream until they reach leaks in the system, where they are deposited on the leak edges, build up and seal the leaks. And, best of all, Aeroseal is 98% effective.

Aeroseal’s patented injection machine contains the following essential components:
