CROSS-LAMINATED TIMBER (CLT)

CLT is a wood panel product made from gluing layers of solid-sawn lumber together. Each layer of boards is usually oriented vertical to adjacent layers and glued on the wide faces of each board, usually in a symmetric way so that the outer layers have the same orientation. Regular timber is an anisotropic material, meaning that the physical features change depending on the direction at which the force is applied. By gluing layers of wood at right angles, the panel is able to achieve better structural rigidity in both directions. It is comparable to plywood but with characteristically  thicker laminations.

CLT has some advantages as a building material, including:

• Design flexibility – CLT has many applications. It can be used in walls, roofs or ceilings. The thickness of the panels can easily be increased by adding more layers and the length of the panels can be increased by joining panels together.
• Eco-friendly – CLT is a renewable, green and sustainable materialsince it is made out of wood and does not require the burning of fossil fuels during production.
• Prefabrication – Floors or walls made from CLT can be fully manufactured before reaching the job site, which decreases lead times and could potentially lower overall construction costs.^[
• Thermal insulation – Being made out of multiple layers of wood, the thermal insulation of CLT can be high depending on the thickness of the panel.
• CLT is a relatively light building material – Foundations do not need to be as large and the machinery required on-site are smaller than those needed to lift heavier buildings materials.

Production

• The production process includes the following phases:
• Analysis of the construction project.
• Adaptation of the project to the CLT solid wood system.
• Production of CLT panels
• Checking the execution of the elements
• Specification of the assembly procedure
• Protection of panels against atmospheric conditions during transport
• Loading
• Preparation of production documentation
  Transport of elements to the place of assembly.

Buildings are erected in approximetly 1 week from delivery on the spot.
