Vario Sun is a thermochromic glass that automatically tints in the presence of heat. Due to its intuitive interlayer, Vario Sun reduces the amount of solar energy being transmitted through the glass.

 

This self tinting glass needs no electrical connections, because it generates its power from the sun itself. Unlike conventional blinds, Vario Sun keeps the natural light balance in the room is always pleasant, without sacrificing the outside view. And unlike traditional tinted glass, Vario Sun lets in the sun’s warming ray, when the temperatures plummet.
