Glulam timber

Types of glulam timber

Glulam timber is a type of engineered wood product that consists of multiple layers of dimensioned lumber glued together with strong, durable adhesive. This gluing process creates a timber beam that is much stronger and more stable than a solid piece of wood, making it an excellent choice for large structural projects. Here are some types of glulam timber:

• Standard Glulam:

  This is the most commonly used type of glulam. It is made of straight laminations and is used in applications where aesthetics are not crucial. It is commonly used in residential construction, such as beams and headers, as well as in barns and workshops. It is also used in commercial buildings and warehouses.

• Curved Glulam:

  This type of glulam consists of curved laminations. It is used in applications where an arched or curved structure is required. This includes the roofs of auditoriums, gymnasiums, and churches, as well as bridges and canopies.

• Post and Beam Glulam:

  This type of glulam consists of a large beam with one or more smaller beams. It is designed for a post-and-beam construction style, where posts and beams support the structure. This type of glulam is popular for use in homes and buildings where a post-and-beam design is desired.

• Architectural Glulam:

  This type of glulam is designed for applications where the appearance is essential. It is made of high-quality, visually appealing laminations. It is used in applications such as exposed beams and architectural features. It is also used in high-end residential and commercial construction.

• Heavy Timber Glulam:

  This type of glulam is made of thick laminations. It is used in applications where a large, heavy-duty beam is required. This includes the roofs of warehouses, industrial buildings, and ski resorts, as well as large-span structures like arenas and exhibition halls.

• Glulam with Tapered Flanges:

  This type of glulam has tapered flanges (the top and bottom parts of the beam). It is used in applications where a lightweight structure is required without sacrificing strength. This includes the roofs of theatres and concert halls, as well as bridges and lightweight roofs.

Features and Functions of Glulam Timber

Glulam timber is engineered wood used in construction projects. It has several features and functions, including:

• High Strength and Load-Bearing Capacity

  Glulam beams are constructed to carry heavy loads. They are used in areas that need support, such as roofs, bridges, and large building ceilings. Glulam beams are strong, making them ideal for supporting structures. They are reliable in preventing collapsing or sagging.

• Long Spans Without Support

  Glulam beams can be used in constructions where wood laminates are glued together. This allows the beams to extend over long distances without support columns in between. This feature creates open spaces or floor plans that enhance the aesthetic appearance of a building.

• Design Versatility

  These beams are flexible in design. Various types of wood can be used to make them, like pine, fir, or cedar. This allows Glulam beams to be tailored to fit different construction needs and designs. Glulam beams can be curved or straight, depending on the architectural design of a building. Their versatility improves the aesthetic function of a building.

• Dimensional Stability

  Glulam beams maintain their shape over time. They are less likely to bend, twist, or shrink compared to regular solid wood beams. This stability is important for the structural integrity and appearance of a building. For instance, stable beams maintain alignment and support even as temperatures and humidity levels change.

• Resistance to Cracking and Splitting

  Glulam beams can resist cracking and splitting. This is because of the way they are constructed, which distributes stress evenly. The beams provide a consistent look and feel. This resistance enhances their durability and reduces the need for repairs.

• Improved Aesthetic Appearance

  Glulam beams offer numerous aesthetic advantages. They can be exposed to highlight the natural beauty of wood with architectural designs. This enhances the warm and rustic appeal of a building. Additionally, the beams can be finished with stains or left natural to improve visual appeal.

• Sustainability and Environmental Benefits

  Glulam timber is made from wood, a renewable resource. This makes Glulam beams more sustainable. They offer environmental benefits compared to other construction materials like steel or concrete. As mentioned, these beams can be made from different types of wood, which promotes the sustainable use of forest resources.

How to choose glulam timber

When choosing glulam beams for sale, buyers should consider several factors to ensure they select glulam timber products that meet their project needs. Here are some of the factors that buyers should consider.

• Load-bearing capacity

  Timber glue lamination creates an opportunity for engineers to design and specify load-bearing capacities. This means that different glulam beams can be manufactured with different load-bearing capacities based on the spacing, support conditions, and span lengths specified by the engineers. As a result, it is important for buyers to consider the load-bearing capacity before choosing glulam beams.

• Moisture content and preservation

  The moisture content of timber affects its strength and durability. A high moisture content means that the timber is still green and has not been dried properly, while a low moisture content means that the timber is too dry. Buyers should purchase glulam timber with a moisture content of 12% or less. In addition, buyers should consider the preservation of the timber. Some glulam timber is preserved to prevent fungi and insect attacks.
