Oriented strand board is almost always significantly cheaper than traditional softwood or hardwood plywood of equivalent thickness. OSB is manufactured using fast-growing, small-diameter wood strands compressed and bonded together under intense heat and pressure with waterproof resins, making the production process highly efficient and cost-effective. In contrast, plywood requires peeling large, high-quality timber logs into thin veneer sheets and layering them carefully, which demands more labor and premium raw materials. This manufacturing efficiency allows builders to save substantial amounts on large-scale framing projects by choosing OSB.
