Abstract: Cross-laminated timber (CLT) is a wood panel made of several layers of dried lumber boards stacked in alternating directions, glued and pressed to form rectangular panels. CLT structural panels have exceptional strength and stability and can be used as floors, walls and roofs in building construction.

Because of its high strength, dimensional stability and design flexibility, CLT is proving to be a highly advantageous alternative to traditional building materials, such as concrete, masonry and steel, in many building types. CLT offers low environmental impacts compared to traditional building materials. Additionally, wood as a building material generally has lower economic and environmental costs but still delivers exceptional beauty, versatility and performance.

CLT panels consist of an odd number of layers of wood (usually, three, five or seven). Panels are customized for each project and each cut to a precise design. Then, the panels are shipped to the construction site for assembly, where panels are fastened together. Because CLT panels are prefabricated and assembled on-site, the length of construction time can be reduced and use of CLT panels generates almost no waste onsite.
