  • Patent number: 12240205
    Abstract: A composite pane includes an outer pane having an exterior-side surface and an interior-side surface, an inner pane having an exterior-side surface and an interior-side surface, and a thermoplastic intermediate layer joining the interior-side surface of the outer pane to the exterior-side surface of the inner pane. The composite pane has a sun shading coating between the outer and inner panes. the sun shading coating includes, starting from the outer pane toward the inner pane, a layer sequence first dielectric module M1, first silver layer Ag1, second dielectric module M2, second silver layer Ag2, third dielectric module M3, third silver layer Ag3, fourth dielectric module M4, wherein the silver layers have, relative to one another, a geometrical layer thickness of 0.4<Ag1/Ag3<1.7, and Ag3 or Ag2 is the thickest silver layer, and wherein the dielectric modules have, relative to one another, an optical layer thickness of M2/M1?1.9, M2/M3?0.8, and M2/M4?1.6.

  • Publication number: 20250019297
    Abstract: A material includes a transparent substrate coated with a functional coating including only two functional metal layers based on silver which are called, starting from the substrate, the first and second functional layers, and three dielectric coatings which are called, starting from the substrate, Di1, Di2 and Di3, each dielectric coating including at least one dielectric layer, such that each functional metal layer is arranged between two dielectric coatings, wherein the first dielectric coating Di1 includes a layer based on silicon zirconium nitride with a high refractive index, SixZryNz, and with an atomic ratio of Zr to the sum of Si+Zr, y/(x+y), higher than 0.20.
