Out on the homestead, every project seems to start the same way — standing in the lumber aisle staring at stacks of wood and wondering, “Which one should I use?” 😊 Two of the most common options you’ll see are OSB (Oriented Strand Board) and plywood. They may look similar at first glance, but they’re actually made quite differently and each one shines in its own way.

We were looking for something to go down as flooring in the attic portion of our house where we could store a few things. We were debating between plywood and OSB.

OSB is made from compressed wood strands that are layered in different directions and bonded with resin and pressure. It has a more textured, patchwork appearance compared to plywood’s smooth layers. One of the biggest advantages of OSB is cost. It’s usually more affordable, which can really add up when you’re covering large areas like wall sheathing, roofing, or subfloors. OSB is also very consistent — it doesn’t have knots or voids, which can sometimes appear in plywood.

Plywood, on the other hand, is made from thin sheets of wood veneer that are stacked with the grain running in alternating directions. This gives plywood excellent strength and durability, especially around edges and fasteners. It also tends to handle moisture a little better than OSB, which is why many builders prefer it for projects where water exposure could happen.

We don’t expect any water in the attic. It’s not going to be walked on. It’s not even going to be accessed that often. It is literally just to sit some things on for storage. So since we found OSB to be half the cost of plywood, we opted for the OSB and it looks great.

At the end of the day, it’s not about which one is better — it’s about choosing the right tool for the job. Just like so many things in homesteading, a little wisdom, a little planning, and the right materials can make all the difference.

And there’s something satisfying about learning these small lessons along the way. Each project teaches us a bit more — not just about building, but about patience, stewardship, and making the most of what the Lord has provided. 

Lord bless, Kyle.
