What is glue laminated timber used for?
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.
What is glue laminated timber called?
Glulam
Glulam (glued-laminated timber) is an engineered structural wood product that consists of multiple individual layers of dimension lumber that are glued together under controlled conditions.
What is the difference between glulam and LVL?
LVL refers to a manufactured timber product made from thin veneers (often 3mm) glued together to form large structural members, often known as Hyspan or similiar. Glulam is made from thicker sections of timber, generally 15-45mm thick, glued together to form a large variety of products.
What is glued wood?
Glued Laminated Wood (Glulam) is a structural material manufactured through the union of individual wood segments. When glued with industrial adhesives (usually Melamine or Polyurethane resin adhesives), this type of wood is highly durable and moisture resistant, capable of generating large pieces and unique shapes.
What are the advantages of laminated timber?
Laminated timber is far superior to solid timber due to its high strength and dimensional stability. Where solid timber posts and beams will crack and twist, a glulam member in the same size (and often smaller) will remain stable for many years as well as retaining its aesthetic appeal.
What is structural glued laminated timber?
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. In North America, the material providing the laminations is termed laminating stock or lamstock.

What are the disadvantages of wood glue?
Disadvantages of Wood Glue
- Weak end grain connections in wood.
- Can only be used on wood and wood products.
- Certain varieties cannot be used outdoors or in wet conditions.
Is glued wood strong?
Wood glue strength ranges from roughly 3,600 to 4,000 psi—that is they can withstand pressures of between 3,600 and 4,000 pounds per square inch. The adhesive bonds of wood glues—as well as epoxies and polyurethane adhesives, both of which can also be used to join wood—are stronger than most woods.
What are the disadvantages of laminated timber?
THE DISADVANTAGES OF LAMINATE FLOORING
- Cannot be refinished. One popular function of natural timber flooring is that it can be sanded back and refinished to renew its appearance over the years.
- Not moisture-proof. Being made of wood, laminate flooring is not impervious to the effects of moisture.
What are glulam timbers and how they are used?
Glue-laminated timber (glulam) is a structural engineered wood product commonly used for beams and columns in residential and commercial applications. It is a highly visible form of mass timber in contemporary projects, with long spans framing signature designs left exposed to take advantage of wood’s natural aesthetic.
What is a cross laminated timber?
Cross-laminated timber. Cross-laminated timber (CLT) (a sub-category of engineered wood) is a wood panel product made from gluing layers of solid-sawn lumber together.
What are glulam beams?
The term glulam is an abbreviated term that stands for glue-laminated timber. A glulam is made with multiple layers of solid wood lumber bonded together with high-strength adhesive to form a single structural unit. Builders often refer collectively to all types of laminated beams or other laminated structural wood materials as glulams.
