The present invention relates to a curtain wall. The curtain wall prevents the flow of cold air or hot air transferred to internal and external frames with an internal insulating material by installing the internal insulating material between the internal and external frames and a window insulating material along an edge of a window facing the internal insulating material, and prevents outdoor cold air or hot air from being inserted into a room or indoor cold air or hot air from being discharged to the outside by preventing the cold air or hot air transferred to the window surface from being inserted into a space between the internal insulating material and the window through the edge of the window. According to the present invention, the cold air or hot air is prevented from being discharged to an exterior space or is inserted into an interior space by a division wall of the internal insulating material and the efficiency of maintaining the temperature is improved since cold air and hot air of adjacent space units push each other in opposite directions based on the division wall of the internal insulating material. Moreover, cold air or hot air transferred to the window surface by the window insulating material is prevented from being inserted into the space between the internal insulating material and the window through the edge of the window and the efficiency of maintaining the temperature is improved since cold air and hot air push each other in opposite directions within an adjacent space based on a gasket to divide the internal insulating material and the window. Therefore, the indoor temperature can be improved and the reliability of a product can be improved. |
