Glued laminated timber, also abbreviated glulam, is a type of structural engineered wood product constituted by layers of dimensional lumber bonded together with durable, moisture-resistant structural adhesives.
A glue-laminated timber is an engineered wood product, meaning it is made from wood but is machined and assembled to precise specifications to create a predictable, dimensionally stable building material. Other common engineered wood products include plywood, oriented strandboard (OSB), and laminated veneer lumber (LVL). A glulam beam looks like a stack of 2 x 4s (or larger lumber) glued together on their broadsides. This contrasts with other engineered members, such as LVL (laminated veneer lumber) and Microlam beams, which look like very thick plywood, with very thin layers of wood glued together to form a thicker mass.
Glulam members are sold in several standard widths and lengths and can be custom fabricated to meet almost any design specifications. They are commonly used for large curved or arching members to build vaulted roofs, domes, and even bridges. Glulam construction offers superior strength and stiffness over dimensional lumber, and pound-for-pound it is stronger than steel. Connections for glulam beams are typically made with bolts or steel dowels and steel plates.
Unique dimensions: Thanks to its high load capacity and low weight, Glulam allows you to cover large areas with small components. It can cover sections of up to 100 meters without intermediate support.
Resistance: Successfully resists various chemicals. It also resists transformations caused by moisture, such as deformations and/or torsions.
Flexibility: Curved, arched, and folded shapes are reproduced quite easily. Pieces also don’t necessarily need to follow the geometry of the tree trunk.
High fire resistance: Structures made of glued laminated wood are safer than unprotected steel in fire. This is because a carbonized layer forms around the Glulam’s core, decreasing oxygen consumption and retarding combustion.
Dimensional stability: Glulam has a humidity of 12%, which corresponds to an equilibrium humidity of 20°C and 65% relative humidity. Contraction and swelling behavior is therefore minimized.
Less need for connections: These structures may require a smaller number of joints when covering large openings without intermediate supports.
Lightness: This feature eases maintenance and assembly/disassembly. Studies show that a Glulam beam has the same strength as a concrete beam of the same volume, yet the weight of the piece of wood is approximately five times less.
