Though the pace of adoption remains slow compared to conventional materials, engineered lumber is starting to make make headway for use in taller wooden buildings, sometimes called “plyscrapers.” Recent developments have helped to shine a light on mass timber use in taller buildings. Engineered lumber is typically made from layers of small pieces of wood joined with adhesive to produce cross-laminated timber (CLT) panels, glulam beams, and laminated veneer lumber. Sometimes called “mass-timber,” the products are not intended to replace typical lightweight stick-frame construction. Instead, architects have been starting to use mass timber to replace concrete and steel in non-residential construction.
