Filmbase,Make Glass do more. A smart glass or switchable glass (also called smart window or switchable window in those applications) is a glass or glazing whose light transmission properties are altered when voltage, light, or heat is applied. In general, the glass changes from transparent to translucent and vice versa, changing from letting light pass through to blocking some (or all) wavelengths of light and vice versa. Smart glass can be constructed by lamination with a smart film or switchable film, often using either glass, acrylic or polycarbonate laminates. Some types of smart films can also be used to convert regular windows into smart glass either using a self-adhesive smart film or special glue. Smart glass technologies include electrochromic, photochromic, thermochromic, suspended-particle, micro-blind, and polymer-dispersed liquid-crystal devices.[1] When installed in the envelope of buildings, smart glass creates climate adaptive building shells. Some advantages of smart windows is that they can eliminate the need for blinds, shades or window treatments. Smart glass can combine many functions, such as natural light adjustment, UV and infrared blocking, advertising and security.
