Glulam - Glued Laminated Timber

Glulam, or Glued Laminated Timber, is a structural wood product consisting of several layers of dimensioned lumber bonded with durable, moisture-resistant adhesive. Appreciated for its high strength-to-weight ratio and dimensional stability, Glulam provides a more durable and versatile alternative to traditional timber. Its ability to be manufactured into virtually any length, shape, or curvature and its pleasing aesthetic appeal make it suitable for various applications in heavy timber construction. As a renewable resource with excellent insulation properties, Glulam supports sustainable and energy-efficient building designs. Despite these advantages, Glulam can be costlier than traditional lumber and requires careful protection and maintenance, particularly when used in exterior applications.

Glulam, short for Glued Laminated Timber, is a type of structural wood product composed of several layers of dimensioned lumber bonded together with durable, moisture-resistant adhesive. Here's why it's used in heavy timber construction:

  • Strength & Durability:
    Glulam has high strength-to-weight ratio, and it's engineered to be stronger and more durable than traditional timber.
  • Versatility:
    Because it's an engineered product, glulam can be manufactured to almost any length, shape, or curvature, making it versatile and suitable for a wide range of applications in construction.
  • Aesthetic Appeal:
    Glulam offers architectural attractiveness with its clean lines and the ability to be finished in a variety of ways.
  • Dimensional Stability:
    Glulam is manufactured to be dimensionally stable, meaning it's less likely to twist, warp, or shrink compared to traditional timber.
  • Sustainability:
    Glulam is a renewable resource and produces less waste during its production than steel or concrete.
  • Thermal Efficiency:
    Glulam has natural insulation properties and, therefore, can contribute to energy-efficient building designs.

However, it's worth noting that glulam may be more expensive than traditional lumber due to the processes involved in its production. Additionally, it must be properly protected and maintained to ensure longevity, especially when used in exterior applications.
