Which engineered wood product is the most prolifically used?

• A. OSB
• B. Plywood
• C. Particle board
• D. MDF

Answer: (A)

Oriented strand board is the most widely used engineered wood panel in modern construction. It’s made from thin wood strands laid in cross layers and bonded with resin, which lets producers use fast-growing, lower-cost wood and create large, uniform sheets. That combination delivers enough strength and stiffness for structural sheathing in walls, roofs, and subfloors at a lower cost than many alternatives, making it the default choice in many building projects. Plywood is strong and versatile but typically more expensive to produce, so OSB often secures the dominant market share in most framing applications. Particle board and MDF are denser and more moisture-sensitive, so they’re favored for furniture, cabinetry, or interior applications rather than structural exterior uses.
