Introduction to Glulam  \nGlulam is manufactured from laminations (lamina) or small sections of timber.  \nDefects such as large knots or cracks are removed, and the grain direction is aligned nearly parallel. The laminations are then bonded together in thickness, width, and length to form a strong engineered wood material.  \nBy drying the timber to a moisture content of 15% or less, and by eliminating inherent weaknesses of solid wood, Glulam minimizes deformation, warping, and cracking while ensuring consistent strength and stability.  \nUnlike synthetic materials, Glulam retains the natural advantages of wood. It can be produced in a wide range of shapes and lengths, making it suitable for diverse applications—from residential houses to large-scale buildings such as Olympic facilities—while maintaining reliable quality.  \nHistory of Glulam  \nIn traditional Japanese architecture, such as temples and castles, multiple vertical timbers were bound together with iron bands or planed joints to form single columns or beams. An example can be seen in the Great Buddha Hall ofTōdai-ji (reconstructed in 1709), where wooden columns reaching 49 meters in height employed a similar joining method.
