Glass buildings and constructions are a commonplace in contemporary cities. They require new approaches in solar glare control. Smart glass perfectly handles this task. Below you can read about different types of switchable glass.
Glass technology is especially interested in 2 its functions: thermal performance and solar radiation protection. Their control can be passive and active.
Photochromic glass (Self-tinting glass)
One of glass types with passive control. Its light transmission depends on intensity of light exposure. This feature of photochromic light is widely used in glass units when it is necessary to glaze large space. Thermal insulation also depends on the level of light exposure. You can buy self-tinting glass in Saudi Arabia.
Thermochromic glass
Optical characteristics of this glass depend on the temperature. It becomes possible due to a special gel which is added to the glass structure. At a certain temperature glass turns into opaque.
Thermochromic glass also belongs to glasses with passive control of light transmission. It works automatically. It can be used for glazing of mansards and roofs.
Smart glass
Its light transmission properties change when voltage is applied. This type of glass is able to block electro-optic emission. Smart-film is the main component that does all work.
There are 3 types of smart glass glass
LC (PDLC) changes transparency of the glass but does not effect its light transmission. Glass turns opal but it does not change level of natural insolation. Window glass looks opaque both from outside and inside of the room.
SPD gives possibility to control the level of both light and solar transmission in the room. This type of glass is electronically tintable by voltage.
Electrochromic glass, same like spd smart glass, but with much longer time of switching.
EVA or PVB film is a usual part of triplex. It is also used in production of antibullet and shatterproof glass. This type of glass is applied not only for facades but also inside buildings. Partitions which divide the office into different zones are quite often made of this switchable glass. There is no need in curtains and sunblind.
Smart glass is cost effective. Smart technology allows to save energy and decrease peak ratings of the power lines. Having glazed windows with smart glass one can lessen air conditioning by 49%, and reduce the cost of room lighting by 51%.
