A vehicle glazing assembly, e.g. a sunroof, comprising a glazing panel 11 with a variable transmission layer, e.g. a liquid crystal film (see Figure 2), the optical transparency of which is temperature dependent such that the layer is optically transparent above a switching temperature. A covering 13 moves relative to the glazing panel 11 between a first position in which at least a portion of the glazing panel 11 is exposed, and a second position in which a smaller portion is exposed or the glazing panel is covered. A sensor 14, in electrical communication with the covering 13, senses when a temperature below or equal to the switching temperature has been reached and subsequently provides a signal to either: a) initiate automatic movement of the covering 13 from the first position to the second position, or b) prevent manual movement of the covering 13 from the second position. Also disclosed is a glazing panel, preferably a laminate, comprising a variable transmission layer, e.g. a liquid crystal film, for use in such an assembly. |
