EVALUATION OF THERMAL INSULATION PERFORMANCE OF WOODEN CLADDING BUILDING USING HEAT TREATED WOOD BY MODEL STRUCTURE

Abstract

In this study, thermal insulation performance of a building covered with a heat-treatment wood was evaluated with four kinds of building models with concrete. The conductive heat flux was smaller than the concrete surface without the cladding through a day. When thickness of the cladding increased, heat transmission coefficient was decreased and transfer of heat was more suppressed through a day. On the other hand, when concrete and a gap of the cladding disappeared, heat transmission coefficient was increased and transfer of heat increased through a day.
