  • Patent number: 10843440
    Abstract: A laminated glazing includes two sheets of glass and a polymer interlayer positioned between them. The first sheet of glass is thicker than the second sheet of glass the thickness of which is less than 1.2 mm. The edge of the second sheet of glass is recessed with respect to the edge of the first sheet of glass over all or part of the periphery of the glazing, thereby making it possible to protect the more fragile second sheet of glass from mechanical knocks against the edge face of the glazing.

  • Patent number: 10724292
    Abstract: A laminated includes two bent glass substrates, a polymer interlayer between the glass substrates, and a notch or orifice cut in an entire thickness of the glazing. The glazing includes a border of compressive edge stresses obtained by general controlled cooling of the substrates in a paired state so that compressive stresses are generated at the border, and a local compression zone, different from the border, and obtained by local controlled cooling of a local area of a main surface of the glazing so that compressive stresses are generated in theid local compression zone. The notch or orifice is located in the local compression zone and made in the substrates in a paired state after forming the local compression zone so that cut contours of the substrates in the notch or orifice have a perfect superposition. The compressive edge stresses of the cut contours are greater than 4 MPa.
