Separated gray metal and titanium nitride solar control members

摘要

A solar control member (50; 62; 70; and 90) for determining solar control for awindow (52) includes an optically massive layer (58; 66; and 80) between a graymetal layer (60; 64; 76; and 86) and a titanium nitride layer (56; 68; 78; and 88).The optically massive layer has sufficient thickness to retard or prevent constructiveand destructive interference of reflected light. The optically massive layermay be an adhesive, but also may be one or more polymeric substrates. The gray metallayer is preferably nickel chromium, but other gray metal materials providesuperior results as compared to the prior art. Also in the preferred embodiment,the titanium nitride layer is closer to the window (e.g., glass) than the graymetal layer.
