열교차단재 적용에 따른 단열문 열성능 비교 분석

Currently, Exterior wall's U-value about building envelope is 0.29∼0.47W/㎡ K(Central Region), but window's one is 3.3W/㎡K according to air gap of glazing, filling gas, coating and type of windows. The door's one is 1.6∼5.5W/㎡?K depending on material and configuration of door. As such, energy loss per unit of door is considerably larger like windows. The door for the recognition was relatively low because energy loss through the door is relatively small compared to window area. In this paper, thermal performance was analyzed through simulation and experiment the door which has thermal break that can improve the insulation performance and doesn't have one.
