INTERLOCKING CROSS-LAMINATED TIMBER: alternative use of waste wood in design and construction

Abstract

This paper presents the research and development of an Interlocking Cross Laminated Timber (ICLT) prefabricated solid wall and roof panel system. Unlike other solid wood panel systems, however, ICLT utilizes no fasteners and no adhesives. Cross-laminated timber (CLT) for North American markets has historically not been feasible due to relative high cost of fabrication, however, developments in CNC technology and sourcing waste and beetle kill standing dead pine from the intermountain region presents a viable option for creating solid wood technology. With growth projections claiming a 100 % increase in building stock before 2030, ICLT is a cost competitive technology for the 3-9 story commercial structures replacing concrete and steel construction, reducing ecological footprint, and increasing indoor air quality of future buildings. This paper presents the research progress of a collaborative team of university researchers and industry partners in developing ICLT for the North American construction market.
