PURPOSE: A producing method of vacuum glass for a sash is provided to form a vacuum condition among glass panels using a simple pressurizing process after ventilating a chamber, and improving a yield by removing an air-suction process through an exhaust pipe. CONSTITUTION: A producing method of vacuum glass for a sash comprises the following steps: preparing a first glass panel(10) and a second glass panel(20); forming pillars(30) on the upper side of the second glass panel; coating hot-melt around the upper edge of the second glass panel to form a hot-melt coating layer(40) with an opening; laminating the first glass panel on the upper side of the second glass panel; inserting the laminated first and second glass panels into a vacuum chamber, and conducting a chamber ventilation; pressurizing the first and second glass panels; cooling the pressurized glass panels at room temperature; and spreading thiocol on the hot-melt coating layer to form a thiokol sealant layer(50).
