At Indy Shed Co., we build our floors with treated 2x6 beams spaced 16in on center, not 2x4s like most builders. We use 3/4 inch Advantech weather-resistant plywood on top of those beams for a nice solid floor.
"There’s good reason to trust AdvanTech subflooring — a combination of long-lasting strength, moisture resistance and nail-holding power. Combined with the polyurethane bond of AdvanTech subfloor adhesive, the AdvanTech Subfloor Assembly offers a panel-to-joist connection so powerful you won’t hear a squeak, guaranteed."
