NLT WG Upgraded to a Technical Committee
In fiscal 2017, the Japan 2×4 Home Builders Association conducted the char margin fire tests under the Nail Laminated Timber (NLT) Working Group. With increasing interest in the market potential of NLT, the Association decided that the Working Group be upgraded to an NLT Technical Committee in fiscal 2018. The number of committee members are anticipated to increase from 8 to 15. This increased emphasis is an indication that the Association foresees NLT as more reasonable and efficient structural element than other wood-based diaphragms such as CLT. The committee will be chaired by Dr. Masahiro Inayama, a professor and an architect, The University of Tokyo. The members also include Yosuke Komiyama, an active architect in Kyoto University. The illustration here is the part of his exhibition at Architectural Institute of Japan, where he proposes a temporary working shelter for fabricating NLT at building sites. In fiscal 2018, it is planned that the NLT technical committee will be actively involved in the publication of an NLT design & installation guide, an NLT demonstration building at Forestry Research and Management Organization in Tsukuba, Ibaraki Prefecture and proposing the building code amendment to allow NLT in PFC structures. COFI Japan will serve as an active member of this NLT Technical Committee.
