This increase in input per unit area due to the strengthening of energy design standards appears to accelerate the growth of insulation market. Therefore, in Korea, the construction of low radiation thin film composite insulation has been increasing in order to improve the thermal resistance of the air cavity and to reduce the thickness of the insulation. As building energy-saving designs become more popular in Korea (notification of Ministry of Land, Infrastructure and Transport), test reports of insulation tests on windows and walls must be approved for new construction. However, it is difficult to measure the thermal insulation performance of low-emissivity insulation only, and the insulation performance of low-emissivity insulation only is not satisfied because it does not satisfy the indices required for thermal insulation performance such as the energy performance index of the energy saving plan. Therefore, in order to derive reference data of low emissivity insulation, this study analyzed and measured the change of insulation performance according to the design factor of low emissivity insulation wall through numerical analysis and model test.
