Abstract: A vacuum insulating glass panel is provided that includes two sheets of glass spaced apart by a predetermined distance, a structured pillar unit disposed between the two sheets of glass where the predetermined distance is a height of the structured pillar unit, and a wall interconnecting edges of the two sheets of glass, wherein space enclosed by the two sheets of glass and the wall is vacuumed to a predetermined pressure level. Vacuum compressive pressure from outer surface of two sheets of glass toward internal vacuum space provides semi-permanent life time. The structure pillar unit may be made of glass or engineering plastic, enabling mass production at affordable price with better quality compared to conventional products.

Abstract: Vacuum insulated glass (VIG) units having ring shaped pillars. The VIG unit comprises two sheets of glass, an edge spacer and multilayer sealants for hermetic sealing of peripheral edge with a high vacuum gap between two sheets of glass. A plurality of pillars is located between two sheets of glass to support vacuum compressive pressure. The ring shaped pillar is made of transparent engineering plastic or glass and can support a compressive strength of 400 MPa or more.
