Which lumber term refers to a product that can be used for structural purposes and is made by laminating layers with adhesive?

• A. Glue-laminated
• B. Engineered wood
• C. Plywood
• D. Solid lumber

Answer: (A)

Laminate layers bonded with adhesive to make a single structural member. Glue-laminated timber, often called glulam, is built by stacking and gluing layers of wood to form a strong beam or column that can span long distances or be curved. The key idea is using multiple wood layers bonded together to create a product that acts as one solid structural piece, which is why this term is the right fit for a structural lumber product made by laminating layers with adhesive. Plywood also uses laminated layers, but it’s typically used as panels or sheathing rather than primarily as a structural beam. Engineered wood is the broad category that includes glulam and plywood, among others, and solid lumber is just a single piece of wood with no lamination.
