CLT solid wood technology is the most advanced wood construction technology
CLT Production involves state-of-the-art computer-controlled factory machinery.
Boards of kiln-dried, finger-jointed spruce are sorted and cut into sheets of up to 10.5m by 2,95m. These sheets are then stacked and glued in press with microwave fixation in perpendicular layers. The panels are available in 3, 4 or 5 board layers.
CLT can be used in all load-bearing and visual structures of the house - base floor, intermediate floor, roof, exterior walls, interior walls, terraces and balconies.
The benefits of
Sustainable and fast grown wood species are used in the manufacturing of the elements. CLT is manufactured conforming to the European quality standards and the whole production process is certified.The CLT-element forms both the finished interior surface and load bearing structure, reducing finishing time significantly.
