What is CLT?

CLT (Cross Laminated Timber) panels are large solid panels made by gluing together layers of wood in a crisscross pattern. These solid panels can be effectively used as structural walls, floors, and roofs.

Due to the cross-laminated bonding, these panels are structurally strong in all directions, enabling the realization of large spans and unique architectural designs, all with a natural aesthetic if desired.

Because of its natural character, structure, and beauty, finishing is not necessary. Additionally, this material positively affects the moisture balance and indoor climate, providing inhabitants with an entirely different experience compared to traditional concrete construction.


Circular construction

Compared to conventional building materials like concrete or steel, wood has the added advantage of being environmentally friendly. Wood serves as a natural carbon sink, with each tree actively absorbing a certain amount of CO2 from the air, contributing to the climate.

When a tree starts decomposing at the end of its lifespan, it releases the stored CO2 back into the atmosphere. If mature trees from sustainably managed European forests are harvested before this CO2 release occurs, and the wood is used in products like CLT, every solid wood building essentially becomes an additional “carbon storage.” In contrast, the production of concrete and steel consumes vast amounts of energy, involving heavy materials that require substantial transportation and emit significant pollutants.

The lower weight of CLT offers numerous advantages. There is reduced need for (heavy) CO2-emitting transportation, and the construction with CLT allows the use of increasingly common electric equipment.

The wooden revolution

Cross Laminated Timber (CLT) is the ultimate solution for making urban areas more sustainable. With CLT, you can achieve spans comparable to those with concrete but with a weight reduction of approximately 70-75%. This translates to a significant potential reduction in foundations and groundwork.

Another crucial advantage of CLT is its suitability for prefabrication. CLT is incredibly dimensionally stable, allowing all electrical conduits and openings to be precisely routed in the factory beforehand. With the rise of Building Information Modeling (BIM) software and the digital pre-construction of homes, known as the digital twin, it is entirely feasible to prepare the entire structure in a 3D model. Subsequently, computer-controlled (CNC) saws can accurately and flawlessly prepare the panels before they are transported to the construction site.

Considering the possible spans, load-bearing capacity, fire safety, and extensive prefabrication capabilities, CLT stands as an excellent substitute for concrete and steel, offering unparalleled sustainability and complete circularity.
