Aeroseal

Aeroseal, LLC is a climate-tech company dedicated to reducing carbon emissions from residential and commercial buildings through advanced air sealing technologies. The company's core innovation originated from research conducted at the Lawrence Berkeley National Laboratory in the early 1990s, funded by the U.S. Department of Energy. This research led to the development of a patented process that seals leaks in air ducts and building envelopes from the inside out, using a precise, computer-controlled injection of aerosolized sealant particles. This technology addresses a critical inefficiency in the built environment, where duct leakage can account for significant energy waste and compromised indoor air quality.

Headquartered in Miamisburg, Ohio, Aeroseal has expanded its operations globally, with a presence in over 27 countries. The company's portfolio includes its flagship duct sealing solution as well as AeroBarrier, a breakthrough technology designed to seal building envelopes in new construction and retrofits. By effectively eliminating air leaks, Aeroseal's solutions enable builders and homeowners to meet rigorous energy codes, improve thermal comfort, and enhance the health of indoor environments. The company continues to innovate within the clean technology sector, driving towards a mission of reducing global carbon emissions by one gigaton annually.
