A solar control window film having high visible light transmission and low transmission of near infrared heat energy is comprised of a transparent substrate bearing a thin, optically transparent layer of metal, an optically transparent layer of near infrared energy absorbing material and a transparent layer of protective material overlying and protecting the near infrared energy absorbing material and the metal. The near infrared reflecting properties and the near infrared absorbing properties of the respective layers are balanced to provide selective solar heat rejection without excessive transfer of heat into the window glass or glazing material.

[ What is claimed is:] [1.] A solar control window film consisting essentially of a substantially transparent substrate bearing thereon an optically transparent metal coating having selected transmission of visible light and selected reflection of visible light and near infrared energy, and an optically transparent layer comprising near infrared energy absorbing material,said window film on clear glass having visible light transmission of from about 50% to about 80%, near infrared energy reflectance of from about 40% to about 60%, near infrared energy absorptance from about 5% to about 35%, and near infrared energy transmission of from about 5% to about 35%.
