“…Various research on wood heat treatment as an environmental-friendly preservative and insect-proof process since the early 2000s has been conducted mainly in Europe. It has been reported that the color of heat-treated wood turns darker, its dimensional stability improves as the hydrophobic property increases, and its weatherproof performance increases (Repellin and Guyonnet, 2005;Esteves et al, 2008;Yoon et al, 2008;Park et al, 2012;2014;2015;. Thanks to such property changes, heat-treated wood is considered to be widely used for garden furniture, fences, pillars, wood storage closets, window frames, doors, furniture, deck materials, outdoor wall materials and flooring materials where dimensional stability or weatherproof performance is required (Esteves and Fereira, 2009;Kim, 2016).…”
