Zusammenfassung:The present invention relates to a complex insulation hinged door provided on a doorway or an entrance of a building, which is characterized by comprising: a main door frame unit having an inner door frame of a synthetic resin material and an outer door frame of a metal material joined to each other; and a main door unit which is rotationally installed on the inside of a main body unit via a hinge, and the inner door frame of a synthetic resin material and the outer door frame of a metal material are coupled to each other. Accordingly, the present invention provides an effect of improving heat insulation performance of the door frame and the door, and increasing strength of a support and reducing the weight, based on a fact which the door frame and the door of the hinged door are composed of a composite material by combining a metal frame and a plastic frame together. 본 발명은 건물의 현관이나 출입구에 설치되는 복합단열 여닫이 도어에 관한 것으로서, 합성수지재의 내부 문틀프레임과 금속재의 외부 문틀프레임이 서로 결합되어 이루어진 메인문틀부와, 이 메인문틀부의 내측에 경첩을 개재해서 회전가능하게 설치되며, 합성수지재의 내부 문짝프레임과 금속재의 외부 문틀프레임이 서로 결합되어 이루어진 메인문짝부를 포함하는 것을 특징으로 한다. 따라서 본 발명은 여닫이 도어의 문틀과 문짝을 금속재의 프레임과 합성수지재의 프레임을 서로 결합하여 복합소재로 구성함으로써, 도어의 문틀과 문짝에 대한 단열성능을 향상시키는 동시에 지지강도를 증가시키고 경량화 할 수 있는 효과를 제공한다.
