Glue-laminated Timber Advantages And Disadvantages

Glue-laminated timber is also known as glulam timber. Several small pieces of lumber are glued together under pressure and heat and make a large timber structure. These structures are used as vertical columns, horizontal beams, and arches. Glue-laminated wood can be easily bent into curve shapes and is available in a variety of species and appearances.

Glulam has been used extensively for decades for commercial and residential projects. Due to its specialty, every constructor likes it. It is perfect for long beam and curved designs that also provide strength with beauty. Laminated boards have better mechanical strength than other materials, resistance to rot and burn.

Advantage of Glulam timber


It is easily available in different sizes in the market. Glulam timber is available in the market in 45mm x 45mm up to 250mm x 1800mm x 30m sizes. 

To handle a roof, the minimum diameter of the column should be 9X9 inches and the length should be 10–12 feet. In such a situation it is difficult to find a complete piece of wood. Therefore glulam timber is useful material. Because glulam timber is made by joining many blocks of wood, it is easily available in large to small sizes.


Their use is mainly used to support the roof. Because we know that a strong pillar is required to reinforce a bulky roof.  It can be easily used anywhere in the roof structure, it is made from many timber layers, so they can be placed at different angles. It is easy to bend because the roof structure requires vertical as well as horizontal support.

Horizontal support used in the roof may be curved. When glulam timber is manufactured it can be easily bent into different angles based on requirements. When it is ready, a solid curved structure is formed which gives the roof a good strength. While using a woodblock, it takes a lot of hard work and time to make a curve.

Easy To Use

Glulam timber is easier to use than steel and concrete. Because it does not require much material and it makes the house feel warm and comfortable as well or gives wooden looks for which people are crazy nowadays.

The best advantage we get is that we can use different types of wood which gives us different colors, characters, and looks.


As we know that timber has very good stress and the ability to withstand weight. On increasing pressure and tension, the wood gets mood due to its flexibility and withstands stress without any damage. While steel and concrete crack.

If we talk about the durability of glulam, it is 2-3 times more durable than steel and concrete.

To increase the durability of our wooden project, it is necessary that we choose the right wood species of glulam. That is, we should choose the wood species according to our project.

Like if we are using glulam for house roof beams and pillars. So we should choose such a species of wood which has good strength to weight ratio. 

If we need wood for a swimming pool, then we should take such glulam which has high humidity and chlorine levels which can remain in contact with water for a long time and do not spoil.


There are some such species of wood, their fire resistance is quite good. The fire resistance of glulam timber is quite good as compared to normal wood as it is a solid structure.

Anti Termite

A common type of wood is likely to be hollow inside and rotten. Due to termites and ants, its structure is weak. And that structure becomes completely hollow and weak within a few years. But if we talk about glulam timber then it is completely solid because it is made by joining several layers together. So the possibility of termites is very less.

The disadvantage of Glulam timber


When we talk about the price, the price of glulam timber is always higher than that of normal timber. Because the cost of production of this timber is associated with the price.


The second disadvantage of glulam timber is its quality. Glulam Timber is made by joining several timber pieces. If defective timber is used in the middle of the timber block during production, this malfunctioning timber can cause the entire timber block to deteriorate. So that after a few years, slowly spoil Timber completely.
