Abstract
A low emissivity, low shading coefficient window consisting of two panes of glass. The first pane having a low wave infrared reflecting and a visible light and shortwave infrared absorbing section of coatings on its inside surface. A second pane spaced about one half inch from the inside surface of the first pane to protect the coatings on the first pane and to insulate the coating. The infrared reflecting section consists of six layers of metals and metal oxides with the stainless steel being used for the absorption of the visible light and shortwave. The first layer consists of a metal oxide selected from the group consisting of tin oxide, zinc oxide, or a combination of zinc and tin oxide. The second layer is of silver or sterling silver. The third layer is stainless steel. The fourth layer is a barrier metal consisting of aluminum titanium, zinc, tin, nickel, chrome or its alloy. The fifth layer is selected from the same group as the first layer. The sixth layer is of titanium oxide.
