Vehicle roof made of glass comprising localized zones of compressive stress

An automotive vehicle equipped with a roof that includes two longitudinal edges and two transverse edges and that is symmetrical with respect to a median longitudinal plane, said roof consisting of a glazing unit comprising at least one mineral glass sheet, said sheet comprising a border of compressive edge stresses and at least two localized zones of compressive stress inside said border, said zones being placed symmetrically relative to said plane of symmetry and each localized zone of compressive stress being less than 30 cm from a longitudinal edge, wherein the two localized zones of compressive stress each surround an orifice, said roof being equipped with roof rails equipped with fastening elements that pass through said orifices.
