Glued Laminated Timber GlulamIntroductionA type of structuraltimberproduct comprising a number of layers ofdimensioned timber bonded together with durable, moisture-resistant structural adhesives.These structural members are used as verticalcolumns, horizontalbeams and curved, arched shapes and is available in a range of species to meet varied end use requirements.Connections are usually made with bolts or plain steel dowels andsteel plates.

Glulam Forms and Sizes available

Available in both custom and stock sizes. Stock beams manufactured in commonly used dimensions and cut to length as ordered and needed.Typical stock beam widths used in residential construction include 3-1/8, 3-1/2, 5-1/8, 5-1/2, and 6-3/4 inches.For spaces where long spans, unusually heavy loads, or other circumstances control the design; custom members are typically specified. Common custom shapes include straight beams, curved beams, pitched members, radial arches, and tudor arches.

Typical Connection Details

Advantages over Traditional Sawn WoodOptimizes the structural values of a renewable resource-Wood. Large glulam members can be manufactured from a variety of smaller trees harvested from second and third-growth forests and plantations. Provides the strength and versatility of large wood members without relying on the old growth-dependent solid-sawn timbers. Reduces the overall amount of wood used when compared to solid sawn timbers by diminishing the negative impact of knots and other small defects in each component board.High strength and stiffness of laminated timbers enable beams and arches to span larger distances without intermediate columns, than the traditional timber construction. The size is limited only by transportation and handling constraints.Advantages over Other MaterialsGlulam has much lowerembodied energythan reinforced concrete and steel (1/6) ;however it entails more energy than solid timber.Glulam is 2/3 the weight of steel and 1/6 that of concrete.It can be manufactured in a variety of straight and curved configurations and hence offers freedom and flexibility without sacrificing structural requirements. Has a greater tensile strength relative to steel ( 2 times on a strength-to-weight basis) and has a greater compressive resistance strength than concrete.
