The purpose of the present invention to solve a problem of a heat insulation property of an existing window utilized for a sliding window installed on a wall surface of a building. Especially, the existing sliding window has many problems of the heat insulation property, watertightness, and airthightness such as problems which rainwater, air, and harmful insects enter via an exposed drain. To solve those problems, the present invention maximizes the heat insulation property, watertightness, and the airthightness by blocking rainwater, air, and harmful insects entered to the inside via the drain of the existing window exposed to the outside by arranging the drain inside and blocking air discharged from the inside to the outside. Additionally, the present invention blocks air sent via the upper part and lateral parts of the sliding window. |
