Glued Laminated Timber (Glulam)

Laminated Timber is a manufactured product that consists of at least three layers of dried wooden boards that are glued together. Usually, Laminated Timber is manufactured from conifers, such as spruce, pine or larch. As individual pieces of lumber are glued together in horizontal layers, it is possible to manufacture large structural members of Laminated Timber in a wide variety of shapes and sizes.

Laminated Timber can be defined as a product which has been manufactured from selected and prepared pieces of wood, and can be supplied in straight, curved and even twisted forms.

Manufacturing Process:

During the manufacturing process the wooden boards are dried until a moisture content of approximately 12% is reached. Then the material is machine graded and evaluated by visual grading. After that the wooden boards are connected by finger-joints. The finger-joined products are manufactured by taking the dried wooden boards, machining a finger profile in each of the pieces, adding the appropriate adhesive and then squeezing the pieces together.

Thanks to material properties such as straightness and stability, Laminated Timber is a very popular product in the timber construction industry and it is often used for supporting structures. When compared with other structural materials, Laminated Timber has several distinct advantages in size capability, variation of cross sections and architectural effects. And the size of Laminated Timber structural members is limited only by the capabilities of the manufacturing plant and the transportation system.
