ABSTRACT OF THE DISCLOSURE A rooftop parapet, for a thermally-insulated curtain-walled building, comprises: a parapet base; a thermally-insulated curtain wall having an upper part spaced apart from the parapet base with a gap therebetween; a moisture-proof sheet covering the gap; a thermally insulating material laid over an upper edge of the paraet base, the moisture roof sheet, and an upper edge of the curtain wall; a waterproof sheet superposed over the insulating material; and a coping plate superposed over the waterproof sheet. Either the moisture-proof sheet or the waterproof sheet has a sagged portion so that the coping plate can follow the deflection of the curtain wall's upper part due to loading of wind pressure effected on the curtain wall. The moisture-proof sheet serves to prevent the thermally insulating material from absorbing moisure inside the building, while the waterproof sheet serves to prevent dewdrops on an inner face of the coping plate from coming down to the insulating material.
