Tall wood is an industry term to identify mass timber buildings that exceed the height limit for wood buildings set by the current International Building Code. Mass timber includes any product currently permitted for use in Type IV construction, such as Cross Laminated Timber, Structural Composite Lumber, glued-laminated timber, and large section sawn lumber.
