Mass timber is a category of framing styles typically characterized by the use of large solid wood panels
used in wall, floor, and roof construction. Products in the mass timber family included Cross-Laminated
Timber (CLT), Glued-Laminated Timbers (glulam), Nail-Laminated Timber (NLT), and Structural
Composite Lumber (SCL) such as Laminated-Veneer Lumber (LVL), Laminated Strand Lumber (LSL), and
Mass Plywood Panels (MPP). Source: reThink Wood – Mass Timber in North America.
