3003 Glass curtain, 1994

Jurgen Bey

The curtain is integrated in a double glass window. The system is based on breaking the light. Glass is transparent , unless it has a texture which makes it opaque. One or both layers of glass are giving a texture by applying a coating on the inside of the glass curtain. By filling the space between the glass panels with fluid the texture making the glass opaque is counteracted. With a raising fluid level, the window becomes transparent from the bottom up.
