Electrochromic glasses have a different function than switchable glasses. The term electrochromism refers to the ability of molecules and crystals to change their optical properties through an external local electric field that affects the electronic states. Electrochromic layers consist of materials that change the light transmission depending on the applied DC voltage.

The microscopically thin coating (mostly tungsten oxide, polyaniline) is activated by weak current and thus changes the color. If the polarity of the voltage is changed, the layer becomes colorless again.

Electrochromic glasses also change the surface structure or color by electrical impulses. Here, the protection against solar radiation and noise is in the foreground. Electrochromic glass is a dimmable glass.
The glass is darkened or lit by a current regulation. The special blue can be controlled as needed by a circuit dark and bright. The regulation can be automated by intelligent solar sensors as needed. In addition, there is the option to control the noise transmission with a dimming control. Electrochromic glass is not a plastic film but a nanostructured glass concept.

It turns blue: This is how switchable glass works
Electrochromism is the ability of particles to change their optics by applying voltage. This means that electrochromic glass changes its color through electrical impulses – from transparent to deep blue. Electrochromic glass, as well as thermochromic or LC glass, is one of the smart glasses. These are glazings that regulate their translucency themselves. How much light is transmitted is dependent on the heating of the glazing or the present electrical voltage.

Compared to true solar thermal energy, which acts on the glass after a certain temperature effect, however, this change in electrochromic glass must be effected by a low current supply of approximately 3 volts.

The electric field then changes the optical properties of the glass: The voltage causes electrical charges to be released to the microscopically thin oxide coating. As a result, the molecules and crystals turn bluish.

Once the tension is removed, the glass returns to its original color – usually transparent. The current is needed only during the process of coloring and decolorizing the glass. The voltage can be controlled manually or automatically, eg by sensors for measuring brightness.

What is the advantage of electrochromic glass?
Due to its dimming function, you no longer need any blinds, roller blinds or similar.

The biggest advantage of electrochromic glass is that you can dispense with blinds, roller blinds or other shading and sun protection systems. Since the operation is often done at the touch of a button, you save time and effort, also the field of vision is not limited.

The rooms, whether in the office or privately, need not be additionally cooled: this saves air conditioning costs. In addition to a pleasant indoor climate, the transparency of the sunshade glazing also remains completely intact in every coloration stage.

Furthermore, electrochromic glasses are very energy efficient, since heat and light control eliminates the cost of air conditioning, fans and other cooling systems.

The glass also requires no special maintenance and can be cleaned just like normal glass. We therefore hold as advantages:

-Optimum use of daylight
-Permanent, unrestricted view to the outside
-Energy efficiency and thus cost savings (in the long run)
-Light transmission window

Electrochromic glass is made up of two discs that lie on top of each other like a sandwich: between the two glasses, which are connected to each other by a nanostructured foil, lies an oxide coating. If voltage is applied here, the glazing is colored. A power supply is not permanently necessary, but only during the coloring phase or in the return of transparency.

The technology of switchable glasses makes it possible to control the amount of light and sunshine in rooms – in response to changing weather conditions of the day and season.

The degree of MHDT dimming can be individually selected by pressing a button in several stages; Alternatively, the regulation of smart windows can also be set up automatically. This is done either via wall switch, remote control, touch or voice sensors.
