The Hemp Build Podcast Ep. 9 presents an interview with Hempitecture’s Tommy Gibbons discussing the building science 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 Jean Lotus is joined by Tommy Gibbons, co-founder of Hempitecture for a deep dive into hemp-based insulation and low-carbon building envelopes.
You'll learn why hemp insulation holds heat longer and keeps indoor temperatures steadier, how it absorbs and releases moisture to help keep walls dry and mold-free, and how it's treated and tested for fire safety. You'll also hear why hemp stores more carbon than it takes to make. Tommy shares stories from real job sites, talks honestly about cost, and explains what to ask for if you're planning to build or renovate with natural materials.
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 co-host Ray Kaderli.
