A low emissivity, low shading coefficient, low reflectance window consisting of two panes of glass. The first pane having a low wave infrared reflecting and a visible light and short wave 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 room form the heat generated on the light and heat absorbing coating of the first pane. The infrared reflecting section consisting of four layers of metals and metal oxides. The first layer of metal oxides selected from the group consisting of tin oxide, zinc oxide and a combination of zinc and tin oxide. The second layer is silver. The third layer consisting of a metal selected from the group consisting of aluminum, titanium, zinc and tin. The fourth layer selected from the same group as the first layer. The visible light and short wave infrared absorbing section consists of a coating of titanium nitride.
