Rice Hull Loose-Fill

Fire: Naturally fire-resistant via silica-cellulose structure — resists sustained combustion

Moisture: Excellent — silica coating resists rot, fungus, insects

Not a WV byproduct — principle transfers but source is regional (rice-growing areas); WV equivalent (buckwheat hull, corn cob grit) unresearched

Verify: find true WV-local silica/lignin-rich ag byproduct equivalent
