How Aeroseal Works in a Retrofit Project | PBS Hometime Segment

PBS Hometime segment with Dean Johnson featuring Aeroseal Duct Sealing technology.

Aeroseal Duct Sealing is a patented breakthrough technology that tackles leaks from the inside out. Aeroseal software allows the technician to measure the duct leakage in residential homes and commercial buildings accurately. The Aeroseal process puts escaping air under pressure and causes polymer particles to stick first to the edges of a leak and then to each other until the leak is closed.

While energy savings resulting from reducing leakage vary based on climate, utility rates, and your heating and cooling system, the other goals of even temperatures in all rooms, improved indoor air quality, and reduction of odors and fumes will be achieved regardless of those conditions. In commercial building applications, Aeroseal also solves air flow and ventilation issues in addition to energy savings.

Aeroseal Duct and Aeroseal Envelope (also known as Aerobarrier) are cutting-edge technologies that deal with air loss in buildings using envelope and duct sealing. Envelope sealing technology addresses major risk management controls when constructing a home, including thermal control, airflow control, and vapor control. Duct sealing, in both homes and commercial properties, reduces one of the biggest contributors to energy waste in U.S. buildings today, leading to higher energy costs and environmental impacts. Aeroseal technology stops these invisible leaks within ducts and the buildings' envelope. Aeroseal improves the lives of people worldwide by delivering comfort, healthy air, and substantial energy savings.
