The present invention relates to a rail hidden type window and door system, including a lower window (or door) frame having a rail cover attached on a main window (or door) frame, a rail hidden by the rail cover and formed on a concave portion of a window (or door) of the main window (or door) frame of an inside of an inlet, and inlet gaskets mounted on a surface member and the rail cover; and a lower window (or door) member having a lower portion enhanced by a supporting portion, an extending portion having a roller supporting member on which a roller groove is formed, and a roller device mounted in the roller groove. Accordingly, the window (or door) is not removed from the rail and is stably opened and closed, while keeping the sealing state to minimize heat loss and preventing water from infiltrating into the interior. |
