Solid timber, solid construction performance

Forte_Credited

Solid timber construction, sometimes called ‘mass timber,’ is an emerging set of engineered wood products—massive planar or frame elements used for walls, floors, roofs, partitions, and core elements of a building. As shown in Figure 1, examples include both glued configurations liked glued-laminated timber (glulam), structural composite lumber (SCL), and cross-laminated timber (CLT), as well as non-glued products like dowel-laminated timber (DLT); nail-laminated timber (NLT), cross-nail-laminated timber (CNLT), and interlocking cross-laminated timber (ICLT).
