Aeroseal Llc

Aeroseal is a climate tech company with a mission to shrink carbon emissions from buildings — as much as 1 gigaton of CO2 annually. The buildings we work and live in generate more than one third of the world’s carbon emissions. Our flagship products, HomeSeal Connect and AeroBarrier Connect, are used to seal the small leaks throughout building walls and HVAC ducts. Manual construction and installation processes once made these leaks an accepted issue. But Aeroseal pressurizes these spaces, injects non-toxic sealant particles into them, and physics brings the particles to all of the often inaccessible and imperceptible leaks. As these leaks are closed off, software monitors the entire process and allows contractors to dial in tightness. We’ve already sealed nearly 200,000 projects, saving billions in wasted energy. It’s why Bill Gates’ Breakthrough Energy Ventures has invested in us. And our global network of more than 600 contractors uses our technology across the globe.
