  • Patent number: 11841519
    Abstract: A window unit is designed to prevent or reduce bird collisions therewith. The window unit may include first and second substrates (e.g., glass substrates) spaced apart from one another, wherein at least one of the substrates supports an ultraviolet (UV) reflecting coating for reflecting UV radiation so that birds are capable of more easily seeing the window. The UV reflecting coating is preferably patterned so that it is not provided across the entirety of the window unit. By making the window more visible to birds, bird collisions and bird deaths can be reduced. The UV reflecting coating is designed to have high UV reflectance across a large range of viewing angles.

  • 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.

  • Patent number: 10556824
    Abstract: A low-emissivity (low-E) coating includes first and second infrared (IR) reflecting layers of or including a material such as silver. The coating includes a bottom dielectric portion including a layer of or including silicon zirconium oxynitride, and a center dielectric portion including a layer of or including zinc stannate. The coating is configured to realize a combination of desirable visible transmission, consistent and low emissivity values, thermal stability upon optional heat treatment such as thermal tempering, desirable U-value, desirable LSG value, and desirable coloration and/or reflectivity values to be achieved. In certain example embodiments, an absorber layer sandwiched between a pair of dielectric layers may be provided in. 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.

  • Patent number: 10227690
    Abstract: A coated article is provided so as to include a low-E (low emissivity) coating having an infrared (IR) reflecting layer sandwiched between at least a pair of dielectric layers. The IR reflecting layer may be of or include a material such as silver (Ag), and is provided between a pair of contact layers. The low-E coating includes an overcoat having a substantially metallic layer (e.g., NbZr or Zr) which has been found to improve the durability of the coating without significantly sacrificing desired optical characteristics. Such coated articles may be used in the context of windows.

  • Patent number: 9776915
    Abstract: An insulating glass (IG) window unit includes first and second substrates, and a low-emissivity (low-E) coating supported by one of the substrates. The low-E coating has two silver based infrared (IR) reflecting layers and allows the IG window unit to realize an increased SHGC to U-value ratio, and an increased thickness ratio of an upper silver based layer of the coating to a bottom silver based layer of the coating. The low-E coating is designed to have a low film-side reflectance, so that for example when the low-E coating is used on surface number three of an IG window unit the IG window unit can realize reduced visible reflectance as viewed from the outside of the building on which the IG window unit is mounted or is to be mounted.
