There are three fundamental approaches to improving the energy performance of glazing products (two or more of these approaches may be combined). The first approach is to alter the glazing material itself by changing its chemical composition or physical characteristics. An example of this is tinted glazing. The second approach is to apply a coating to the glazing material surface. Reflective coatings and films were developed to reduce heat gain and glare, and more recently, low-emittance coatings have been developed to improve both heating and cooling season performance. The third approach is to assemble various layers of glazing and control the properties of the spaces between the layers. These strategies include the use of two or more panes or films, low-conductance gas fills between the layers, and thermally improved edge spacers.
