Abstract
An insulated glass unit (IGU) comprises impact resistant safety films on the inner surfaces of the glass panes, providing an impact resistant, energy-saving IGU for use in windows and doors. A layer of the safety film providing energy savings may be trimmed from the edges of a glass pane; witch may be sealed within the interior of the IGU, preventing corrosion while providing no loss in impact resistance. A scratch-resistant, chemical vapor deposited coating may be added to an interior glass surface (i.e. facing the building interior) in order to prevent heat loss from the building. An IGU may have an Energy Star rating for both summer and winter use.
