Ten years after the invention of a "Lego-style" interlocking hempcrete block captured the imagination of the hemp building world, the technology is making a comeback under a new name and a revamped business model.

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.

In Episode 5 of the Hemp Build Podcast, host Ray Kaderli goes inside the Cleburne, Texas facility of CannaVision with CEO David Russell to show how industrial hemp is processed into consistent, construction-ready materials. You’ll see hemp bales fresh from the field, how fiber and woody core are separated, how materials are sized and refined, and how precision processing makes hemp suitable for real-world building applications—from hemp-lime (hempcrete) walls to plasters, insulation, and bio-composites.
