Airplane window having infrared heat reflection capability

A window assembly particularly for use in a commercial airplane is provided. Many windows are provided on most commercial passenger airplanes. Solar radiation causes the passage of infrared heat radiation through each window assembly into the passenger cabin during daylight hours. The disclosure involves the window assemblies of airplanes and the use of a protective coating that is bonded to the outermost surface of an outermost window pane, with the outermost window pane bonded to an inner window pane of the airplane window assembly. The protective coating has a metallic element component that has the capability of reflecting an effective amount of infrared heat radiation from solar radiation away from passing through the window assembly and into the cabin of the airplane.
