Here is the future of construction with cross-laminated timber: a remarkable innovation offering stability, versatility and good looks. Explore its varied applications and dive into a world where durability and creativity come together harmoniously.
The cross-laminated timber machine: innovations, advantages and applications
Cross-laminated timber, also known as CLT (Cross Laminated Timber) or X-Lam, embodies a major advance in the field of timber construction. This versatile and innovative material offers a fascinating alternative to traditional building methods.
The fundamental concept of cross-laminated timber
An ingenious multi-layer assembly
Cross-laminated timber stands out for its ingenious design in several layers of timber laminations. Each layer is made up of laminations laid in a specific direction, and these layers are then crossed at an angle of 90 degrees. This crossing method gives the panels exceptional stability in all directions, which helps to prevent cracks from spreading. What is more, the mechanical properties of this material are considerably improved compared with traditional solid timber.
Manufacture and choice of materials
The manufacture of cross-laminated timber involves the use of specific adhesives, such as phenol-resorcinol-formaldehyde (PRF), polyurethane (PUR) or emulsion polymer isocyanate (EPI). The timber laminations are joined, by a process called finger jointing, to create elements of great length. This material can be made from various types of wood, such as fir, spruce, maritime pine, Scots pine or Douglas fir.
The exceptional advantages of cross-laminated timber
Increased stability and rigidity
One of the major assets of cross-laminated timber lies in its dimensional stability and its rigidity. Thanks to the crossing of the layers of laminations, this material offers superior mechanical performance, which makes it a favoured choice for applications requiring increased strength and durability.
Versatility of application
Cross-laminated timber is used successfully in a variety of applications. From floors to load-bearing walls and roofs, this material adapts perfectly to modern building challenges. Emblematic projects, such as the Stadthaus apartment complex in London, demonstrate the ability of cross-laminated timber to support large-scale structures.
Implications for the construction industry
A promising future
The rise of cross-laminated timber in the construction industry is undeniable. Continuing advances in research and development aim to maximise performance while reducing production costs. Although the material may raise concerns because of the use of adhesives and the question of recycling, projects such as hybrid CLT bear witness to a commitment to innovation and sustainability.
Towards an architectural revolution: cross-laminated timber at the heart of innovation
Cross-laminated timber is positioning itself as a revolution in the construction sector, offering a unique combination of stability, versatility and durability. Its cross-layered design gives it exceptional mechanical properties, making this material a choice option for large-scale projects. The construction industry continues to explore the possibilities of cross-laminated timber, thereby paving the way for a promising and sustainable future.

Load-bearing structures and main frames
Long-span load-bearing elements
One of the most striking applications of cross-laminated timber is in the creation of load-bearing elements with long spans. CLT panels are used to make floors, load-bearing walls and roofs in various types of building. Thanks to its dimensional stability and its high strength, cross-laminated timber makes it possible to design durable and reliable structures.
Multi-storey buildings
Cross-laminated timber has also paved the way for the construction of buildings with several storeys in timber. From residential complexes to commercial buildings, this material offers an environmentally friendly and solid alternative to conventional building methods. Examples such as the Stadthaus in London and the Sensations building in Strasbourg demonstrate the ability of cross-laminated timber to support tall structures.
Appearance and finishes
Façade cladding
Cross-laminated timber is not limited to the structure alone. It is also used to create attractive and durable façade cladding. This cladding adds a visual dimension to buildings, while offering protection against the elements. CLT panels can be carved and shaped to give façades a distinctive appearance.
Modern and sustainable interiors
In interior spaces, cross-laminated timber brings a warm and modern atmosphere. The panels can be used for partitions, ceilings and floor coverings, thereby creating visual consistency across the spaces. What is more, cross-laminated timber meets environmental standards thanks to its durability and its ability to store carbon.
