| Advantech OSB will outlast conventional plywood by a mile in the rain. I exposed it, flat (the worst way possible) as subfloor, to rains for 1+ year while building my house with only maybe 1mm of fiber degrading on the surface a few places. Many modern OSBs use hydrophobic glues impermeable to water. |

| Marine ply would be my choice |

| ▲ | BizarroLand a day ago | parent [-] | | If it were going to be exposed to the elements, I would pick a pine and waterseal it or a marine ply and waterseal it. It would fail eventually anyway, but either of those two options, depending on price, would be good and cheap enough to last. |
