Commonly called “smart film” uses electro chromic technology to allow users to manually switch glass from a transparent to an opaque state. Switchable glass film is often applied to interior glass walls, windows and doors, as it provides a dynamic layer of privacy when needed. It can also be used as a backdrop for projectors and other means of collaboration. the biggest drawbacks in certain “smart film” solutions is the inability to reduce solar heat gain and protect against UV transmission through glass. Similarly, most switchable films are battery operated, thereby requiring added maintenance over time. Most projects involving switchable film are interior glass applications, such as commercial office buildings, governmental agencies, and educational facilities. While these unique films provide transformational qualities required for privacy, they often lack the sun and temperature control capabilities that transitional film delivers.
