  • Publication number: 20210122145
    Abstract: A laminated glazing comprising first and second sheets of glass joined together by an interlayer structure comprising at least a first layer of adhesive interlayer material is disclosed. The surface compressive stress in a central region of a first major surface of the first sheet of glass is dependent upon the thickness of the first sheet of glass. For a thickness t of the first sheet of glass between 1.4 mm and 2.6 mm the minimum surface compressive stress CSmin (in MPa) in the central region of the first major surface of the first sheet of glass is given by CSmin(MPa)=21.0×t3?118.6×t2+236.9×t?a1, wherein a1 is between 135 MPa and 140 MPa. The second sheet of glass may be a sheet of chemically strengthened glass having a thickness between 0.3 mm and 1.0 mm. The laminated glazing may be fixed or movable in an aperture in a vehicle.

  • Publication number: 20210114354
    Abstract: A laminated glazing comprising first and second sheets of glass joined together by an interlayer structure comprising at least first and second layers of adhesive interlayer material with a support sheet therebetween is disclosed. The laminated glazing is arranged such that the first layer of adhesive interlayer material is between the first sheet of glass and the support sheet, the second layer of adhesive interlayer material is between the second sheet of glass and the support sheet support material and at least a portion of the second major surface of the first sheet of glazing material faces the first major surface of the second sheet of glazing material. In the event of breakage of the first sheet of glass, the second layer of adhesive interlayer material remains attached to the support sheet thereby keeping the second glass sheet from becoming detached from the laminated glazing.

  • Patent number: 10919800
    Abstract: Methods are disclosed for planarisation of a coated glass substrate by deposition of a silazane based layer thereon. Coated substrates according to the invention exhibit improved properties in terms of reduced roughness, lower haze and higher visible light transmission and the coated surface may be exposed to the external environment, for example as surface 1 or surface 4 of a double glazing unit. The resulting smooth surface is less susceptible to marking and scratch damage, and offers enhanced surface energy (improved hydrophobicity).

  • Patent number: 10882780
    Abstract: A glazing comprises a glass substrate having an enamel layer adhered to at least a first surface portion, the enamel comprising 20 to 80 wt % frit and 10 to 50 wt % inorganic pigment. The thickness of the enamel layer is 2 ?m to 50 ?m, and the inorganic pigment has an infra-red reflectance such that the infra-red reflectance of the first portion of the glass substrate surface is 37% or higher over a region in the wavelength range 800 nm to 2250 nm. The glazing may be laminated, and may be a vehicle windscreen. A process for producing the glazing involves applying ink to a glass substrate, curing the ink thereby producing an enamel adhered to the glass substrate, and shaping the glass substrate by heating to a temperature above 570° C. The preferred inorganic pigments are of the Fe and/or Cr type in spinel, haematite or corundum crystal form.
