Smart glass and window is made up of special glass which changes light transmittance properties across a spectrum. The characteristics of these glasses can be varied depending on the ambient conditions with the help of heat voltage or light applied as per needs of the occupants. With increasing technological advancement, these glasses ensure user comfort, energy effectiveness, proper fuel consumption and blockage of harmful radiation among others. The smart glass and window market is composed of two technology types which include active and passive. The active segment is further subdivided into polymer dispersed liquid crystals (PDLC), suspended particle device (SPD), electrochromic and others. Moreover, the passive segment is classified into passive photochromic and passive thermochromic. Active smart glass and window market held the largest market share in 2014, owing to dynamic light transmission adjustment property using a single switch. By application, the smart glass and window market is segmented into automotive, aircraft, construction and marine. The automotive sector accounted for the largest market share in 2014, primarily due to increasing demand for eco friendly solutions, fuel efficacy and passenger safety among others. The market is classified into four geographic regions - North America, Europe, Asia Pacific, and Rest of the World.
