A curtain wall having seismic resistance according to an aspect of the present invention includes a frame having a grid-shaped vertical bar and a horizontal bar to form a plurality of partition spaces, a glass provided in the partition space of the frame, and a pair of adjacent to each other A heat insulating member made of a plastic material that is located between the glass and is coupled with one surface of the outdoor side of the frame to increase thermal insulation performance, is fastened to both sides in the width direction of the heat insulating member, is coupled with one surface of the outdoor side of the frame, and has elasticity due to an earthquake A pair of elastic members made of a synthetic resin material for absorbing and reducing the generated waves to minimize the waves from being transmitted to the frame, wherein the elastic members are separated from the vertical bars and the horizontal bars forming the partition space. By individually absorbing the waves generated by the earthquake, it is possible to alleviate the torsional impact applied to the glass.
