Laminated glazing unit

A method of fabrication of a laminated glazing unit, comprising

• a first and a second glass sheet, the first glass sheet being equipped with a first through-hole;
• a spacer film of thermoplastic polymer disposed between the first and second glass sheets, and
• one or more conducting wires buried within the spacer film or disposed between the spacer film and the first glass sheet or disposed between the spacer film and the second glass sheet, each conducting wire having a first end and a second end that is opposite the first end, each conducting wire extending continuously from the first end to the second end and having a portion that extends along a depth of the first through-hole so that each second end of the conducting wire exits from the laminated glazing unit via the first through-hole in the first glass sheet and the second end is located outside said first through-hole,
• wherein a connector is arranged at the second end of the conducting wire,
• the method comprising:
• supplying the first and the second glass sheet;
• cutting out the first through-hole in the first glass sheet;
• where necessary, forming the first and second glass sheets;
• supplying the one or more conducting wires and the film of thermoplastic polymer optionally equipped with a through-hole, and attaching the one or more conducting wires onto the film of thermoplastic polymer;
• installing the film of thermoplastic polymer carrying the one or more conducting wires between the first and second glass sheets, and feeding out an end of the one or more conducting wires via the first through-hole;
• degassing under vacuum an assembly formed by the first and second glass sheets and the installed film of thermoplastic polymer, with use of a peripheral seal or of a vacuum bag, together with an adhesive for blocking the first through-hole in the first glass sheet, or of a sucker for sucking out the air via the first through-hole in the first glass sheet;
• heat sealing edges of the laminated glazing unit and edges of the first through-hole, and
• autoclaving the assembly.
