The invention discloses an electrically heated window having minimised hot spots. The window comprises at least two plies of a glazing material having a ply of an interlayer material laminated therebetween. An array of heating wires is carried by one of the plies, the heating wires extending between a first electrical connection means and a second electrical connection means for supplying current through the wires, the first and second electrical connection means being substantially parallel to each other. The first electrical connection means is shaped so as to define a wire-free area to allow a data signal to be transmitted through the window to a device positioned in the vicinity of the wire-free area. The second electrical connection means is shaped to correspond to the first electrical connection means, such that the heating wires in the array have a substantially constant length.
