The “Gigacorn” Blueprint: Inside AeroSeal’s Global Push to Cut Building Waste

What if climate impact didn’t require behavior change — just better building practices?

In this episode of Green Disruptors, Megan sits down with Ross MacPherson of AeroSeal to talk about the power of air sealing. From ductwork to entire building envelopes, AeroSeal’s technology is transforming energy efficiency in both residential and commercial construction.

Ross shares how the company is scaling across 90+ countries, why energy codes are the biggest marketing lever no one talks about, and how AeroSeal’s “gigacorn” ambition (yep, that’s a billion tons of CO₂ reduced per year) is surprisingly achievable. Builders save money. Occupants gain comfort. And emissions go down — all without needing anyone to remember their reusable grocery bags.
