Manufactured by bonding or laminating together smaller pieces of wood, engineered lumber is stronger than traditional lumber and does not shrink, warp or twist. Because of its strength, engineered wood is typically used as structural load-bearing "I" joists for framing roofs, ceilings and floors.
Glue Laminated Timber is a type of engineered wood that is made by bonding together lumber pieces with thicknesses of less than 2 inches. The ends of individual pieces are joined together to make longer laminations that are face-bonded to form the finished products. Another engineered wood called laminated veneer lumber is formed from thin wood veneers that are bonded together in large billets with veneer grains parallel to the long direction.Learn more about Building Materials
