Abstract

A vacuum panel includes a jacket having a bottom that is formed into a "pan" shape. A top is welded to the flanges of the bottom to create a hermetic seal therebetween. A dense glass fiber mat fills the jacket. A getter is strategically located in the panel to absorb residual gases in the panel and maintain the vacuum life. To create the vacuum in the panel, the panel is heated to a specified temperature and time, and evacuated through an opening. The opening is sealed with a braze seal that is melted over the opening.
