A laminated glazing includes two transparent substrates which are separated by a lamination interlayer, and intended for fitting out buildings or vehicles. One of the transparent substrates is coated with a functional coating capable of acting on solar radiation and/or infrared radiation, and a low emissivity (so-called “low E”) coating is provided on one of the faces of the second substrate.

The invention relates to a glass substrate including a stack of coating layers having control properties, in which stack comprises at least one niobium metal layer located between a layer of a dielectric material selected from Si.sub.3N.sub.4 or TiOx and a layer of a protective metal material selected from TIN or Ni—Cr, conferring solar control and heat resistance properties on the glass substrate.

A composite pane includes an outer pane, an inner pane, and a thermoplastic intermediate layer. The composite pane has, between the outer and inner panes, a solar protection coating that substantially reflects or absorbs rays outside the visible spectrum of solar radiation. The solar protection coating includes starting from the outer pane, a layer sequence of first dielectric module (M1), first silver layer (Ag1), second dielectric module (M2), second silver layer (Ag2), third dielectric module (M3), third dielectric module (M3), third silver layer (Ag3), fourth dielectric module (M4), wherein the silver layers (Ag1, Ag2, Ag3) have a layer thickness relative to one another of Ag1/Ag2>1 and Ag1/Ag3>1, and the dielectric modules (M1, M2, M3, M4) have a relative layer thickness of M2/M1>1, M2/M3>1, and M2/M4>1.

Multilayer metallo-dielectric energy control coatings are disclosed in which one or more layers are formed from a hydrogenated metal nitride dielectric, which may be hydrogenated during or after dielectric deposition. Properties of the multilayer coating may be configured by appropriately tuning the hydrogen concentration (and/or the spatial profile thereof) in one or more hydrogenated metal nitride dielectric layers. One or more metal layers of the multilayer coating may be formed on a hydrogenated nitride dielectric layer, thereby facilitating adhesion of the metal with a low percolation threshold and enabling the formation of thin metal layers that exhibit substantial transparency in the visible spectrum. Optical properties of the coating may be tuned through modulation of metal-dielectric interface roughness and dispersion of metal nanoparticles in the dielectric layer. Electrical busbars and micro-nano electrical grids may be integrated with one or more metal layers to provide functionality such as de-icing and defogging.

Certain example embodiments relate to electric, potentially-driven shades usable with insulating glass (IG) units, IG units including such shades, and/or associated methods. In such a unit, a dynamic shade is located between the substrates defining the IG unit, and is movable between retracted and extended positions. The dynamic shade includes on-glass layers including a transparent conductor and an insulator or dielectric film, as well as a shutter.
