The present invention relates to a door for an apartment house capable of reducing impact noise generated between a door and a door frame when the door is opened or closed and minimizing the inflow and the outflow of living noise through the top, the bottom, and the two lateral sides of the door when the door is closed, by installing a gap blocking unit inside the door frame and on the floor where the door frame is installed and also installing a finishing material capable of being closely attached to the gap blocking unit around the four edges of the door. The present invention includes: a door of which the edges are rounded and around the four edges of which a material having a semi-arc groove at the center is installed; a door frame to which the door is installed using a hinge in a way the door can be opened or closed; and a gap blocking unit which is installed while being inserted into an insertion groove formed on the inner top part and the two lateral sides of the door frame and on the floor where the door frame is installed and blocks the gap around the four edges of the door by being closely attached inside the semi-arc groove of the material which is installed around the four edges of the door. |
