Certain example embodiments of this invention relate to evacuation and sealing techniques for VIG units, and / or multi-chamber vacuum ovens for accomplishing the same. In certain example embodiments, a VIG assembly is inserted into a multi-chamber apparatus to successively reduce the chamber pressure and thus the pressure between substrates comprising the VIG assembly until a final evacuation pressure is reached. Once the final evacuation pressure is reached, a pump-out port or tube of the VIG assembly is sealed forming a VIG unit while the VIG assembly is still in the vacuum chamber. After sealing, chamber pressures are gradually increased to atmospheric while the gap between the substrates of the VIG unit remains at a pressure less than atmospheric which is close to the final evacuation pressure.

Vacuum-insulated glass (VIG) windows (10) that employ glass-bump spacers (50) and two or more glass panes (20) are disclosed. The glass-bump spacers are formed in the surface (24) of one of the glass panes (20) and consist of the glass material from the body portion (23) of the glass pane. Thus, the glass-bump spacers are integrally formed in the glass pane, as opposed to being discrete spacer elements that need to be added and fixed to the glass pane. Methods of forming VIG windows are also disclosed. The methods include forming the glass-bump spacers by irradiating a glass pane with a focused beam (112F) from a laser (110). Heating effects in the glass cause the glass to locally expand, thereby forming a glass-bump spacer. The process is repeated at different locations in the glass pane to form an array of glass-bump spacers. A second glass pane is brought into contact with the glass-bump spacers, and the edges (28F, 28B) sealed. The resulting sealed interior region (40) is then evacuated to a vacuum pressure of less than one atmosphere.

A method of producing a vacuum between two glass sheets to form an insulating glazing. One of the sheets has a hole drilled in its thickness. Spacers are placed between the two glass sheets with the sealing joint being placed around the periphery of the sheets. A vacuum is created between the sheets through the hole which is then closed. The spacers are fixed on one of the sheets by bonding with a mineral compound covering at least the bonding zones on the glass sheet. The second sheet is placed on the spacers and on the peripheral sealing joint. The peripheral sealing and the bonding with the spacers are simultaneously effected by raising the temperature.

In certain example embodiments of this invention, a window unit may include a vacuum IG (VIG) unit as an inboard lite and a monolithic lite (e.g., with an optional low-E coating thereon) as an outboard lite. A dead air space may separate the inboard and outboard lites. A highly insulated frame may be used to support the inner and outer lites. The VIG unit may be partially embedded or supported in the insulative frame, so that the insulating frame separates the VIG unit inboard lite from the outboard lite thereby reducing conductivity around the edges of the window unit so that R-value can be increased (and U-value decreased). In certain example embodiments, the total R-value of the window unit is at least about R-8, and more preferably at least about R-10 (compared to the much lower R-values of conventional IG units).

Certain example embodiments of this invention relate to edge sealing techniques for vacuum insulating glass (VIG) units.

In certain example embodiments, infrared (IR) heating elements are controllable to emit IR radiation at a peak wavelength in the near infrared (NIR) and / or short wave infrared (SWIR) band(s), and the peak wavelength may be varied by adjusting the voltage applied to the IR heating elements. The peak wavelength may be selected so as to preferentially heat the frit material used to form a VIG edge seal while reducing the amount of heat provided to substrates of the VIG unit. In certain example embodiments, the substrates of the VIG unit do not reach a temperature of 325 degrees C. for more than 1 minute.

Certain example embodiments of this invention relate to articles including anticondensation and / or low-E coatings that are exposed to an external environment, and / or methods of making the same.

The articles of certain example embodiments may be, for example, skylights, vehicle windows or windshields, IG units, VIG units, refrigerator / freezer doors, and / or the like.
