Window Glass Coatings

Abstract

Thin film coatings modulate optical and thermal and other properties of window glass. Coated window glasses influence indoor climate and energy efficiency in buildings. They can be classified into groups of spectrally selective glazings, chromogenic glazed systems for switchable smart window technologies and light-enhancing transparent materials. Low-emissivity glazings are typical of spectrally selective window glasses. Chromogenics have applications in light control and switching technologies that are optically, thermally, chemically or electrically activated. Transparent materials with micro-structured or holographic films and antireflective coatings serve to direct light and control light functions. An overview of several types of window glazings and coatings will be presented.
