TEXTURED GLASS SHEET WITH RECTILINEAR FEATURES

摘要

The invention relates to a transparent glass sheet comprising a first face provided with a texturing 1 via a plurality of relief features that are convex, rectilinear and parallel to one another extending all along said face and distributed over the whole of said face, and a second face provided with a texturing 2 via a plurality of relief features that are concave, rectilinear and parallel to one another extending all along said face and distributed over the whole of said face, the features of the texturing 2 being such that: (i) the ratio of the height h2 of the features of the texturing 2 to the dimension b2 of the base thereof is such that 0.05 ≤ h2/b2 ≤ 2; (ii) the ratio of the height h2 of the features of the texturing 2 to the height h1 of the features of the texturing 1 is such that: 0.2 ≤ h2/h1 ≤ 4; and (iii) the ratio of the number n2 of features of the texturing 2 to the number n1 of features of the texturing 1 is such that: n2/n1 ≥ 0.03 and n2/n1 < 1. Such a glass sheet has good light trapping properties, a low fouling tendency and is toughenable. It is furthermore easy to handle and cut.
