Cross Laminated Timber (CLT) is a structural engineered wood panel, which can be used to construct walls, floors, and roofs. CLT panels are prefabricated and are constructed to specific building requirements, making them available in a variety of sizes and configurations. CLT panels are constructed in directional alternating layers using kiln-dried lumber boards. Typically three to seven boards are used, bound with structural adhesives such as polyurethane, emulsion polymer isocyanate (EPI), melamine-formaldehyde, or phenol-resorcinol-formaldehyde adhesives. Formaldehyde-free adhesives, such as polyurethane, were found to be most common. When CLT is specified beyond typical lumber sizes, lumber is finger-jointed and bound with an adhesive. Adhesives used for finger-jointing and between layers may be the same within a product or may be different. This CP assumes the same adhesive for both applications.
