Aeroseal, a climate-tech startup with a system to reduce energy leaks to almost zero in some buildings, is receiving a $67 million Series B funding round led by Breakthrough Energy Ventures and Climate Investment.
“Buildings are a critical, yet hard to decarbonize, sector, and Aeroseal’s technology is quickly making an immediate impact on emissions,” said Carmichael Roberts of Breakthrough Energy Ventures. “The company’s solution will make it easier to electrify both new and existing buildings by significantly reducing HVAC demand and mitigating wasted energy from conventional heating and cooling systems.”
With support from several top U.S. home builders and a network of specialized HVAC dealers in the U.S. and Canada, Aeroseal has sealed 260,000 buildings (residential and commercial) since its inception. Company CEO Amit Gupta says that with the new funding, Aeroseal hopes to secure that many buildings annually within three years.
“We expect our momentum to continue with the world’s increased demand for healthier energy-efficient spaces, tighter regulations, and greater incentives tied to adopting newer codes,” Gupta said. “This is just the beginning.”
Aeroseal’s technology delivers sticky polymers into a building’s air ducts and envelopes to create seals where manual sealing methods can’t.
“Aeroseal’s approach to reducing energy consumption in buildings by addressing air leakage is truly innovative and industry-leading,” said Marc Van Den Berg, Global Managing Director for Ventures at Climate Investment. “Its products have been proven to reduce energy consumption by an average of 30%, significantly impacting the environment and building operations. We are proud to have Aeroseal as a valued member of our Climate Investment portfolio.”
