About

Aeroseal is a breakthrough duct sealing technology that seals leaks from inside the duct system using a patented non-toxic aerosol mist. Developed at Lawrence Berkeley National Laboratory with partial funding from the U.S. Department of Energy, the technology addresses problems associated with the energy waste caused by duct leakage. Because the process is done from the inside, it also eliminates the demolition typically required to find and seal leaks using traditional duct sealing methods. The Aeroseal process has proven to be the most effective, affordable and viable method for sealing leaky ductwork systems in commercial buildings. The computer-controlled system automatically measures duct leakage rates before, during and after the sealing process and generates a final report that documents the results. Once the leaks are sealed, fan speeds can be reduced dramatically – thereby reducing payback time and increasing energy savings for institutions such as hospitals, labs, universities, K-12 schools and military facilities.
