Engineered wood products, glued building products "engineered" for application-specific performance requirements, are often used in construction and industrial applications. Glued engineered wood products are manufactured by bonding together wood strands, veneers, lumber or other forms of wood fiber with glue to form a larger, more efficient composite structural unit.<ref name="apawood">{{cite web|url=http://www.apawood.org/pdfs/download_pdf.cfm?PDFFilename=managed/E30.pdf|title=APA – The Engineered Wood Association|work=apawood.org|url-status=live|archive-url=https://web.archive.org/web/20060627045932/http://www.apawood.org/pdfs/download_pdf.cfm?PDFFilename=managed%2FE30.pdf|archive-date=June 27, 2006|df=mdy-all}}</ref>

These products include [[glued laminated timber]] (glulam), wood structural panels (including [[plywood]], [[oriented strand board]] and composite panels), [[laminated veneer lumber]] (LVL) and other structural composite lumber (SCL) products, [[parallel strand lumber]], and I-joists.<ref name="apawood" /> Approximately 100 million cubic meters of wood was consumed for this purpose in 1991.<ref name="Horst-2005"/> The trends suggest that particle board and fiber board will overtake plywood.

Wood unsuitable for construction in its native form may be broken down mechanically (into fibers or chips) or chemically (into cellulose) and used as a raw material for other building materials, such as engineered wood, as well as [[particle board|chipboard]], [[hardboard]], and [[medium-density fiberboard]] (MDF). Such wood derivatives are widely used: wood fibers are an important component of most paper, and cellulose is used as a component of some [[Organic compound#Synthetic compounds|synthetic materials]]. Wood derivatives can be used for kinds of flooring, for example [[laminate flooring]].
