ABSTRACT:
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 parapet base, the moisture-proof 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 wind pressure acting on the curtain wall. The moisture-proof sheet serves to prevent the thermally insulating material from absorbing moisture 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.
