ELECTROCHROMIC

Electrochromic materials are used to control the amount of light and heat. They have found use in the transport sector to automatically tint rear-view mirrors.

Electrochromic materials can change colour upon application of an electrical current and can be composed of various materials and structures.

Low-voltage electrical charges are passed across a microscopically-thin coating on the glass surface, activating the electrochromic layer.

The electric current can be activated manually or triggered by light sensors to reduce solar heat gain into the building.

The stacked electrochromic layers act like a battery, the electrodes and electrolyte of which constitute thin layers of transparent minerals which change with the electrical charge.

In the absence of any voltage, the glass retains its previous colouration. The glass draws current only during the colouring and clearing phases.
