Abstract

Further conservation of energy continues to be a major priority, even with the advances that have been made in reducing our present consumption. For while energy use has gone down, costs continue to grow. Homeowners continue to look for ways to keep their fuel costs down. Buyers of new homes expect new construction to feature the latest in energy-efficient products such as insulated windows. Many insulated glass units (IGU's) have a thin film coating on one or two of the inner surfaces (#2 and #3) of the unit. Figure 1 illustrates such a unit.
