Finger Joint Laminated Timber (FJLT) is a wood product made by combining several pieces of wood using finger joints. The production process involves joining two or more logs using a special adhesive and high pressure. The selected wood usually consists of smaller pieces or production waste that will be processed again into a stronger and bigger material.
Advantages, Characteristics, and Weaknesses of Finger Joint Laminated Timber
Production process Finger Joint Laminated Timber making use of wood scraps that are often discarded, thereby reducing waste and over-cutting of trees. In addition, the use of environmentally friendly adhesives and wood from sustainably managed forests forest wood makes this wood type a better choice from an environmental point of view than solid wood or other construction materials.
This type of wood has a uniform and stable structure due to the production process involving splicing the finger joints. This reduces the risk of splitting or shrinking that often occurs in solid wood. It’s good resistance to changes in temperature and humidity, makes it strong against deformation or cracking.
Thanks to its stability and environmental resilience, FJLT has a long lifespan, making it a valuable investment in long-term construction projects. It can also be processed and treated like regular solid wood, simplifying the finishing, coloring, and protection processes against wood-destroying organisms such as termites and fungi.
This type of timber has an attractive appearance with a unique pattern derived from the natural wood touch. Finger joint patterns add an aesthetic touch and artistic value to the building structure.

Finger Joint Laminated Timber still contains wood, making it susceptible to attacks from wood-destroying organisms such as termites and fungi. Therefore, protection with chemicals or other treatment methods is often necessary. Additionally, its production cost is higher than regular solid wood due to the use of specialized adhesives and high pressure.
FJLT offers an attractive and sustainable alternative in the construction industry. Its sustainability, stability, larger sizes, and natural aesthetics make it increasingly popular and sought after by architects, engineers, and developers. Despite having some drawbacks, advancements in technology and improvements in the production process will further enhance the potential of Finger Joint Laminated Timber as a future construction material that is more environmentally friendly and highly durable.
