Which term best describes wood products such as Glulam beams and OSB?

• A. Engineered Wood
• B. I-Joists
• C. Solid Wood
• D. Laminates

Answer: (A)

Engineered wood describes wood products formed by bonding wood components with adhesives to create a finished material that has properties not possible with a single piece of solid wood. Glulam beams are glue-laminated, meaning multiple pieces of lumber are bonded together to form long, strong beams. OSB is made from wood strands laid in cross-oriented layers and pressed with resin adhesives into panels. This manufacturing approach gives predictable strength and stability, so these products are classified as engineered wood rather than solid wood. Laminates and I-joists refer to more specific or different forms, while solid wood would describe a single natural piece. So, engineered wood is the best umbrella term for both.
