Abstract
An improved process for fabrication of laminated glazings incorporating conductors such as heating elements is described. During assembly of the glazing, a solution comprising the same polymer material as the interlayer is applied to the conductors and allowed to dry prior to fitting a glazing sheet on top. This gives rise to a thin coating of polymer around the conductors and subsequent heat treatment causes the this coating and the main polymer interlayer to soften and fuse. The resulting structure shows improved encapsulation of the conductors (wires and busbars) with greater resistance to water ingress at the edge of the glazing.
