Hemp Build Podcast Ep. 7: Is Natural Fiber Insulation Ready for Mainstream Buildings?
By Hemp Build School
The Hemp Build Podcast Ep. 7 presents an interview with Hempitecture’s Mattie Mead and Annie Ball discussing the history of hemp batt fiber insulation and how specifiers can achieve lower embodied carbon and more healthy spaces with a natural plant fiber instead of spray foam or mineral wool insulation.
The series spotlights leaders in the hemp building industry and is tailored to architects seeking continuing education (CE) credits.
In this episode of the HempBuild Podcast, host Ray Kaderli is joined by Mattie Mead, co-founder of Hempitecture, and Annie Ball, LEED AP BD+C and material researcher, for a deep dive into hemp-based insulation and low-carbon building envelopes.
They break down how natural fiber insulation compares to conventional materials, why embodied carbon matters more than ever, and how hemp insulation performs when it comes to fire safety, indoor air quality, moisture control, and thermal comfort. The conversation also explores real-world adoption challenges—from contractor hesitation to code compliance—and how “drop-in” insulation products are helping builders and designers reduce climate impact without reinventing their workflows.
Whether you’re a builder, architect, homeowner, or sustainability enthusiast, this episode offers a practical look at how insulation choices affect health, safety, comfort, and climate performance—and why the building envelope is one of the biggest levers for change.
“Architects are looking to renew their continuing ed credits, and we want to give them something in a new format new to acquire their credits,” said Kaderli.
