Abstract (en)

[origin: WO2006048897A1] A material that provides a different degree of screening in the two directions of sight according to the intensity of the light that illuminates the two sides of a pane (P1) is obtained through a calibrated opacification of a portion of the surface of at least one of the sides so as to leave a plurality of transparent regions (R). In particular, the working of said surface is such that the total area of said transparent regions (R) is from 10% to 45% of the area of the pane (P1), the area of the single transparent region (R) is from 0,5 mm<SUP>2</SUP> to 5 mm<SUP>2</SUP> and the light transmission factor of the opacified region is from 75% to 90%, so as to obtain a global light transmission factor of the whole pane (P1) between 80% and 95%.
