  • Patent number: 11498867
    Abstract: A coated article incudes a low-emissivity (low-E) coating having at least one infrared (IR) reflecting layer of or including a material such as silver or the like. The low-E coating is designed so that the coated article can realize a low U-value in combination with a high solar heat gain (g value). In the top dielectric portion of the coating above the silver, a high-low-high refractive index sequence is provided. This allows for a low U-value and a higher g value to be obtained for a given silver thickness. Coated articles herein may be used in the context of insulating glass (IG) window units, or in other suitable applications such as monolithic window applications, laminated windows, and/or the like.

  • Publication number: 20220259916
    Abstract: The subject matter of this invention is a polygonal heat-insulating glass panel with straight edges and a flat surface, in which the two parallel flat glass panes (1) enclosing the inner space of the glass panel are connected to each other, at least on one side, by a transparent, hermetically sealed spacer (2), forming a closed frame with the other sides. The transparent spacer (2) is composed of an adhesive mould incorporating a transparent adhesive body (5) and an adhesive flange (6) applied between an outer edge sealing glass strip (4.1) and an inner edge sealing glass strip (4.2), where the width of the outer edge sealing glass strip (4.1) matches that of the glass panel, while the width of the inner edge sealing glass strip (4.2) closing the inner space of the glass panel matches that of the inner space of the glass panel.

  • Patent number: 11236014
    Abstract: Certain example embodiments relate to ultra-fast laser treatment of silver-inclusive (low-emissivity) low-E coatings, coated articles including such coatings, and/or associated methods. The low-E coating is formed on a substrate (e.g., borosilicate or soda lime silica glass), with the low-E coating including at least one sputter-deposited silver-based layer, and with each said silver-based layer being sandwiched between one or more dielectric layers. The low-E coating is exposed to laser pulses having a duration of no more than 10?12 seconds, a wavelength of 355-500 nm, and an energy density of more than 30 kW/cm2. The exposing is performed so as to avoid increasing temperature of the low-E coating to more than 300 degrees C. while also reducing (a) grain boundaries with respect to, and vacancies in, each said silver-based layer, (b) each said silver-based layer's refractive index, and (c) emissivity of the low-E coating compared to its as-deposited form.

  • Patent number: 11112538
    Abstract: A first coating is provided on a first side of a glass substrate, and a second coating is provided on a second side of the glass substrate, directly or indirectly. The coatings are designed to reduce color change of the overall coated article, from the perspective of a viewer, upon heat treatment (e.g., thermal tempering and/or heat strengthening) and/or to have respective reflective coloration that substantially compensates for each other. For instance, from the perspective of a viewer of the coated article, the first coating may experience a positive a* color value shift due to heat treatment (HT), while the second coating experiences a negative a* color shift due to the HT. Thus, from the perspective of the viewer, color change due to HT (e.g., thermal tempering) can be reduced or minimized, so that non-heat-treated versions and heat treated versions of the coated article appear similar to the viewer.

  • Patent number: 10882997
    Abstract: A coated article is provided with a low-emissivity (low-E) coating on a glass substrate. The low-E coating includes an infrared (IR) reflecting layer between at least a pair of dielectric layers. The IR reflecting layer may be of silver or the like. The coating is designed so as to provide a highly transparent coated article that is thermally stable upon optional heat treatment and which can be made to have a low emissivity in a consistent manner. The coating is designed to have improved IR reflecting layer quality, and thus reduced tolerances with respect to manufacturability of desired emissivity values. The coated article may be used in monolithic window applications, IG window applications, or the like.

  • Patent number: 10766808
    Abstract: This invention relates to a coated article including a low-emissivity (low-E) coating. In certain example embodiments, the low-E coating is provided on a substrate (e.g., glass substrate) and includes at least first and second infrared (IR) reflecting layers (e.g., silver based layers) that are spaced apart by contact layers (e.g., NiCr based layers) and a dielectric layer of or including a material such as silicon nitride. The dielectric layer is split by a layer of or including zirconium oxide, in order to improve durability. In certain example embodiments, the coated article has a low visible transmission (e.g., no greater than 60%, more preferably no greater than about 55%, and most preferably no greater than about 50%).

  • Patent number: 10696584
    Abstract: A coated article includes a low emissivity (low-E) coating supported by a glass substrate. The low-E coating includes at least one silver (Ag) based infrared (IR) reflecting layer(s) that is provided adjacent to and contacting at least one contact layer of or including Ag, Ni and Cr. The provision of a contact layer(s) including at least Ag, Ni and Cr, directly over and contacting a silver-based IR reflecting layer, has been found to advantageously increase visible transmission (Tvis) of the low-E coating. Such low-E coating may be used in applications such as monolithic windows, insulated glass (IG) window units, and the like.

  • Patent number: 10611678
    Abstract: In certain example embodiments, a coated article includes a carbon-doped zirconium based layer before heat treatment (HT).

  • Patent number: 10586689
    Abstract: Certain example embodiments relate to sputtering apparatuses that include a plurality of targets such that a first one or ones of target(s) may be used for sputtering in a first mode, while a second one or ones of target(s) may be used for sputtering in a second mode. Modes may be switched in certain example embodiments by rotating the position of the targets, e.g., such that one or more target(s) to be used protrude into the main chamber of the apparatus, while one or more target(s) to be unused are recessed into a body portion of a cathode of (e.g., integrally formed with) the sputtering apparatus. The targets may be cylindrical magnetic targets or planar targets. At least one target location also may be made to accommodate an ion beam source.

  • Patent number: 10472274
    Abstract: Certain example embodiments relate to heating a ceramic paint applied to a portion of a coated article in order to at least partially “eat through” the underlying coating, with any remaining materials being removable by washing, and associated articles. In certain example embodiments, the coatings are multilayer sputter-deposited coatings formed on a glass or other substrate. The heat may be provided in connection with conventional heat treatment (e.g., thermal tempering) and/or heat bending processes that otherwise would be performed on the coated article.

  • Patent number: 10472880
    Abstract: Certain example embodiments of this invention relate to insulating glass (IG) units including three substantially parallel spaced apart glass substrates, wherein at least two of the surfaces include low-emissivity (low-E) coatings and at least some of the non-low E coated surfaces have antireflective (AR) coatings disposed thereon. In certain example embodiments, low-E coatings are provided on the second and fifth surfaces of the IG unit, and each internal surface of the IG unit that does not support a low-E coating does support an AR coating. Additional AR coatings may be provided on one or both of the outermost surfaces in certain example embodiments. In some cases, the center substrate need not be heat treated because of the reduced absorption enabled by providing the low-E coatings on the two outermost substrates, as well as the reduced heat accumulation in the center lite itself and in the two adjacent spacers.
