Abstract: A spandrel panel is provided which has at least one low visible light transmittance pane having a composition such that the low visible light transmittance pane exhibits, when measured utilizing Illuminant D65, a visible light transmittance (Tvis) of 15% or less. In the past, spandrel panels were typically constructed with a film or coating, for example a frit, disposed on at least one surface of one of the panes or with a sheet of opaque material positioned within or next to the spandrel panel. In the present invention, obtaining low visible light transmittance through the spandrel panel is achieved via the chemical composition of at least one of the panes. This results in a lower cost spandrel panel.
