Separated functional layer stack and titanium nitride layer for achieving solar control

摘要

A solar control member (50; 62; 70; and 90) for determining solar control for a window (52) includes an optically massive layer (58; 66; and 80) between an optically functional layer stack (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 constructive and destructive interference of reflected light. The optically massive layer may be an adhesive, but also may be one or more polymeric substrates. The layer stack may be a Fabry-Perot interference filter. Also in the preferred embodiment, the titanium nitride layer is closer to the window (e.g., glass) than the layer stack.
