By using the thermal conductivity and temperature gradient for each type of structural wood materials using larches, this study calculated the heat conduction (Qc). Through this, the potential insulation improvement of structural material was verified. Furthermore, by fabricating a cross-laminated timber (CLT) using conventional insulators such as gypsum board and sound-absorbing board, the insulation performance improvement effect was investigated based on the heat conduction, and the optimal ratio of cross lamination was derived. In the result of measuring the temperature gradient of upper and lower parts of structural wood materials, the plywood-core CLT showed about 10°C higher temperature gradient than the laminated wood and CLT under a same condition. This means that the plywood-core CLT has better efficiency of using energy than other wood materials. Through this, it is determined that effect of economic efficiency improvement can be expected with respect to heating and cooling if plywood-core CLT is used as a wall. Six types of plywood-core CLT with high-insulation property, in which the gypsum and sound-absorbing insulators were cross-laminated in a certain ratio, showed lower heat conduction than the laminated wood, CLT, and plywood-core CLT. Particularly, the gypsum board-inserted plywood-core CLT (27.6% gypsum) showed the lowest heat conduction of about 0.6 W. This result was 35.8% lower thanthat of larch-laminated wood, 36.4% lower than that of CLT, and about 40% lower than that of plywood-core CLT. Through these results, it is determined that the insulator-inserted wood material can be used as a substitute for conventional walls of internal insulation structure.
