A laminated glazing that selectively controls the transmittance of light through the glass in response to control signals, said glazing made from an assembly comprising: at least one layer of clear glass having first and second oppositely disposed major faces; an IR-reflective layer that reflects light in the infrared spectrum; a first interlayer that absorbs light in the ultraviolet spectrum and in the visible light spectrum, said interlayer having first and second oppositely disposed major faces, wherein said first interlayer comprises a layer of thermoplastic material with enhanced ultraviolet light absorption for the light spectrum with wavelength below 410 nanometers and autoclaving temperatures less than 100°C; wherein the thermoplastic material is not polyvinyl butyral; a switchable film having first and second major faces that are oppositely disposed from each other, the transmittance of visible light between said first and second major faces of said switchable film being variable in response to control signals applied to said switchable film, the first major face of said switchable film facing the second major face of said interlayer, said IR-reflective layer being between said second oppositely disposed major face of said layer of clear glass and said switchable film, and said first interlayer also being between said second oppositely disposed major face of said layer of clear glass and said switchable film; a second interlayer having first and second oppositely disposed major faces with the first major face of said second interlayer facing the second major face of said switchable film; and a second glass layer having first and second oppositely disposed major faces with the first major face of said second glass layer facing the second major face of said second interlayer, wherein said laminated glazing defines an outside edge, said laminated glazing further comprising a border layer that is located between the perimeter of said switchable film and the outside edge of said laminated glazing, wherein said switchable film having an edge surface that is disposed between the first and second major faces of said switchable film, said laminated glazing further comprising a polyimide barrier that is secured to the edge of said switchable film, said barrier material having low permeability to said interlayers (16, 20). at least one layer of clear glass having first and second oppositely disposed major faces; an IR-reflective layer that reflects light in the infrared spectrum; a first interlayer that absorbs light in the ultraviolet spectrum and in the visible light spectrum, said interlayer having first and second oppositely disposed major faces, wherein said first interlayer comprises a layer of thermoplastic material with enhanced ultraviolet light absorption for the light spectrum with wavelength below 410 nanometers and autoclaving temperatures less than 100°C; wherein the thermoplastic material is not polyvinyl butyral; a switchable film having first and second major faces that are oppositely disposed from each other, the transmittance of visible light between said first and second major faces of said switchable film being variable in response to control signals applied to said switchable film, the first major face of said switchable film facing the second major face of said interlayer, said IR-reflective layer being between said second oppositely disposed major face of said layer of clear glass and said switchable film, and said first interlayer also being between said second oppositely disposed major face of said layer of clear glass and said switchable film; a second interlayer having first and second oppositely disposed major faces with the first major face of said second interlayer facing the second major face of said switchable film; and a second glass layer having first and second oppositely disposed major faces with the first major face of said second glass layer facing the second major face of said second interlayer, wherein said laminated glazing defines an outside edge, said laminated glazing further comprising a border layer that is located between the perimeter of said switchable film and the outside edge of said laminated glazing, wherein said switchable film having an edge surface that is disposed between the first and second major faces of said switchable film, said laminated glazing further comprising a polyimide barrier that is secured to the edge of said switchable film, said barrier material having low permeability to said interlayers (16, 20).
