The world's constructions that we use for anything from living to office spaces and production facilities have a huge impact on the world's carbon footprint. This is why it is important to make sure that not only do we build more sustainably, but also that we renovate our existing constructions.

ESG Today writes that 2010-founded Aeroseal uses an innovative process to insulate the ventilation systems of all buildings, in the form of non-toxic polymers. This means that no physical access is required to fix any potential leakage that would increase the cost of energy.

Aeroseal officials claim that their solution is 50% more efficient than others on the market and can reduce both labor costs and time by up to 70%. With 260.000 homes and thousands of commercial buildings sealed already across the globe, the Ohio-based company helped reducing 500.000 tons of the world's CO2 emissions.

Amit Gupta, CEO of Aeroseal, said that "the industry is taking notice of this ‘easy button,’ with several top U.S. builders already adopting Aeroseal’s duct and envelope sealing technologies. We expect momentum to continue with increased demand for healthier energy-efficient spaces, tighter regulations, and greater statewide incentives for adopting newer codes."

Bill Gates' Breakthrough Energy Ventures and Climate Investment were among the VCs that financed the 67 million USD round.
