What is glulam?

Glue-laminated timber (glulam) is the name given to large solid wood members manufactured by gluing many smaller pieces together. Glulam is an engineered structural material consisting of a number of graded, kiln dried and selected full length laminations – usually 45 mm thick – bonded with proven adhesives, to form a solid member of practically any length, shape or size.
The main reason for laminating is to produce larger size members than possible in solid sawn timber. There is also an increase in strength. The strength of a single piece of timber is as strong as its weakest point, which is usually the largest knot.In laminating, the weakest point of one piece of timber is bonded to the higher strength of adjoining pieces, thus forming an homogeneous structural component of great efficiency.
