 SPD Glass incorporates suspended particle device
(SPD) technology.
Light absorbing microscopic particles are dispersed within a specially formulated emulsion, which is suspended, between layers of film. This film, in turn, can be enclosed within a variety of transparent materials, ranging from glass to plastic.
The particles within the film are activated by applying a low voltage, which forces them to align at various angles, resulting in a range of transparencies to control the amount of heat and light passing through the material. |
