The present invention relates to a door assembly for door fixation and insulation. The door assembly comprises: a door (10) which has a receiving space (11) in the lower side in the longitudinal direction and an installation unit (12) connected to the receiving space (11) by a side; a locking unit (20) which is installed in the installation unit (12) to allow a lever to be operated up and down; and a barrier (30) which is accommodated in the receiving space (11) to be moved up and down by the locking unit (20). Therefore, the door assembly prevents the door from being easily closed by wind or the like when the door without a door frame is opened and prevents the loss of thermal energy for the air conditioning of a room while the door is closed. |
