Types of construction timber – what can we distinguish?
Wood is considered to be a material with exceptional durability, aesthetics and versatility. However, in order to use them for construction, it must meet certain requirements and parameters. It should be free of defects, have the right level of moisture (which affects the strength of the material), and be properly impregnated. What are the most important types of construction timber? Take a look at our overview and learn more about the characteristics and applications of the different types of structural timber.

Are you wondering what properties different types of construction timber have? Discover the most important information about each of them.
1. GLT Wood
Glulam, also known as glulam, is a material that consists of several layers of wood that are glued together under high pressure. These layers are laid so that the wood fibers run parallel to each other, which increases the strength and stability of the material.
GLT is widely used in structures where high strength and bending resistance are required. It is used in the construction of bridges, large sports halls, churches and other facilities where it is necessary to use long, free-standing structural elements.
2. CLT wood
CLT is a material consisting of several layers of wood laid crosswise and then glued together. This design provides high load capacity in different directions and dimensional stability.
CLT is ideal for the construction of multi-storey residential and commercial buildings. Its advantage is the possibility of prefabrication, which speeds up the construction process and minimizes waste on the construction site. CLT is also used in the construction of walls, ceilings and roofs.
3. LVL wood
LVL is a type of engineered wood made from thin layers of veneer that are glued under pressure in one direction. This design makes LVL characterized by high strength to bending, compression and torsion.
LVL is commonly used in structures that require high strength and stability, such as floor joists, lintels, columns and roof structures. Its advantage is the ability to produce large-sized elements and ease of processing.
4. OSB wood
OSB is a wood-based board that is made of wood chips laid in layers and glued under pressure. These layers are laid alternately, which ensures high strength and dimensional stability.
OSB is often used in construction as a material for the construction of walls, ceilings and roofs. It is also used for the production of prefabricated elements, as well as a material for temporary structures such as formwork or temporary fencing.
5. LSL Wood
LSL is a material consisting of long wood chips glued under pressure. It has high compressive and flexural strength, as well as good dimensional stability.
LSL is used in structures that require high strength, such as floor beams, columns, and roof structure elements. Its advantage is the ability to produce large-sized and uniform quality components.
Types of construction timber. What do you need to pay attention to when choosing?
When choosing the right type of construction timber such as GLT, CLT, LVL, OSB, plywood, and LSL, you need to consider several essential factors. Consider technical parameters such as load capacity, dimensional stability and weather resistance. Be sure to analyze the cost of the material and its availability in the local market. When choosing a material, also look at the specific design and environmental requirements to ensure compliance with building standards and minimize environmental impact.
