Key Takeaways
Jacob's company prefabricates structural straw-panel SIPs in factory conditions, bringing a centuries-old material into a modern high-performance building system.
Straw bale delivers very high insulation value in thick (~14-inch) walls, and its tubular fibers trap air much like an insulated cup.
Straw is among the most moisture-resilient building materials Jacob has tested, absorbing and releasing more moisture safely within a 24-hour drying window than many alternatives.
Modern straw construction 'breaks the bale' into panels rather than stacking whole bales, unlocking design flexibility and the popular modern farmhouse look.
Service cavities inboard of the wall let trades run structure and utilities without ever clawing back into the insulation or the air barrier.
The team's guiding adage is 'a good hat and a good coat', meaning proper roof overhangs plus flashing and layering are the real keys to managing water risk.
Because straw is essentially open-source technology, Jacob's path to scale is a co-manufacturing network of regional fabricators rather than one giant plant, contrasted with Europe's robotic EcoCocon facility.
