Description

Low-E films for application to windows have been in use since 1978. The most extensive use throughout the world has been for retrofit application to windows in existing buildings. The low emittance, high infrared reflectance of these films provide a significant reduction in the window U-value. Additionally, when combined with the solar control features of conventional sun control window films, the low-E results in improved shading coefficient values. The key to the design of low-E films for retrofit application is the protective cover layer for the low emittance, thin metallic coatings. Infrared transparent materials, which provide good physical and chemical protection, have been incorporated yielding a minimum of five years life expectancy in retrofit environments. Window manufacturers are also using low-E films in the construction of new high performance windows.
