How smart glass windows work

Smart glass windows utilise SPD technology. With SPDs, suspended particle devices, a thin laminate of nano-scale particles is suspended in a liquid and placed between two pieces of glass.

When voltage is not applied, the suspended particles are randomly organized, blocking and absorbing light from passing through the window (opaque mode).

When voltage is applied, the suspended particles align and allow light to pass through the window (transparent mode).

By varying the voltage, the direction of the suspended particles changes, controlling the tint of the windows and the amount of light transmitted.

SPD smart glass windows can essentially be manually or automatically “tuned” to precisely control the amount of light, glare and heat passing through.
