Rice-hull bagwall construction is a system of building,[1] with results aesthetically similar to the use of earthbag or cob construction.[2] Woven polypropylene bags (or tubes) are tightly filled with raw rice-hulls, and these are stacked up, layer upon layer, with strands of four-pronged barbed wire between. A surrounding "cage" composed of mats of welded or woven steel mesh (remesh or "poultry wire") on both sides (wired together between bag layers with, for example, rebar tie-wire) and then stuccoed, to form building walls.

Fireproofing

Mixing rice-hulls in boric acid and borax solution results in fireproofing. A similar result can be achieved if placed on top of poured ingot, which applies direct heat until turned into ash. In addition, its ash form does not appeal to vermin.[3]
