ristkihtliimpuit

Ristkihtliimpuit, also known as cross-laminated timber (CLT), is an engineered wood panel produced by stacking several boards in alternating grain directions and bonding them with structural adhesive. Common configurations use three to seven layers, oriented at right angles to each other, and the resulting panels are pressed under heat and pressure to create a rigid, stable sheet.

The cross-lamination gives CLT high strength and stiffness in both directions, enabling its use for walls, floors, and roofs. Panels can be produced in large formats with varying thicknesses and sizes to suit different structural and architectural needs. Manufacturing relies on high-quality timber from responsibly managed forests and durable adhesives, yielding a prefabricated element that can be shipped to construction sites for rapid assembly.

Applications include residential, commercial, and industrial buildings, particularly where a timber primary structure is desired or required. CLT panels are favored for rapid erection, reduced on-site waste, and the possibility of prefabrication, which can improve construction timelines and accuracy. They also offer favorable thermal performance and can contribute to lower overall embodied carbon compared with concrete and steel when sourced and produced responsibly.

Sustainability and standards: CLT is considered a renewable, low-embodied-carbon option when wood is harvested from certified forests. It is covered by regional standards and building codes that address mechanical performance, fire safety, and durability. Designers note that CLT requires attention to moisture management and protective detailing for exterior applications to ensure long-term performance.
