01
Own it for less
One material family. No lifetime of stacked replacements.
Lower cost to own.
Storm-ready. Quick recovery.
A hemp-based building system for coastal work — built to cost less over time, stand up to weather, and get back in service fast after an event.
Chapter 0 · The Paradigm
We don't sell panels.
We create one structure.
Most buildings fail as assemblies — five products, five trades, five insurance events.
Conventional envelopes are a sandwich: sheathing, insulation, wraps, and finishes stacked by different crews. Phyto-Board is the opposite premise — one reactive chemistry, graded by density, packed into a binder-coated timber skeleton so floor, wall, and ceiling — one chemistry, one family of hemp-based products. OSB4 is how the market keeps score; we take share by retiring the sandwich, not by joining the wall.
Chapter I · The Pillars
Five reasons the envelope is the asset.
02
Run it for less
Mass and continuity cut the energy to heat, cool, and keep dry.
03
Insure it for less
Repair is pack-and-recast in the same binder.
04
Recover faster
Designed for wind, impact, and fire. Time-to-use is cure, not rebuild.
05
Keep the value open
Hemp first. Open technology. A certified system — not corporate lock-in.
Chapter · The Pathway
Crawl. Walk. Prove.
Crawl
Baseline we hold
We have a baseline formulation — validated through internal testing and work experience with the chemistry and build process.
Walk
Regional qualification
We are evaluating regional materials so they can be qualified against a global building reference (Americhanvre as the comparison standard).
Prove
How we prove the system
We will be testing to ASTM standards as a system, against our FMEA-guided IP testing procedures. We use ISO 9001 guidelines for tracking and DOE experiments to produce useful results.
Three Densities · One Chemistry
Not three boards for a lumberyard aisle.
HD armor, MD face, LT infill react around a binder-coated timber skeleton. One chemistry. One family of hemp-based products.
- HD — Exterior armor
- MD — Interior face
- LT — Frame infill
8′ × 16′ field kit · Precut frame. Pretreated hurd. Measured binder. Add water. Pack. It cures to one shelter.

OSB4 GRADE
Water-soak target on the exterior armor
We generate data against OSB4-class benchmarks because that is where code and insurers already keep score. The product on the scoreboard is the whole envelope.
One kit. Precut, numbered,
ready for the field.
Portable monolithic hemp-geopolymer shelter — timber skeleton, reactive infill, HD/MD skins. Ships as a shell.

For NGOs, disaster relief, and rebuild programs. Add water. Pack. It cures to one shelter.

Chapter IV · The Studio
Built to change how we own a building — not who owns the category.
Phyto-Board is led by a polymer scientist whose career runs through coatings chemistry and wood-panel manufacturing — PPG, Sherwin-Williams, Valspar, Willamette Valley. That bench is the foundation of the hemp-mineral binder.
- 01 Low cost of ownership
- 02 Low energy cost to maintain
- 03 Low insurance, because repair is cheap
- 04 Weather-event designed. Fast recovery
- 05 Open technology. Certified system. Hemp first.
