Abstract
A laminated glazing comprising, a first ply of a glazing material, a second ply of a glazing material, a film having an electrically conductive coating, the film being located between the first ply and the second ply, and a first busbar in electrical contact with the electrically conductive coating, the first busbar comprising an expansion portion, the expansion portion comprising a bridging busbar portion or a gap in the first busbar. Methods for producing the laminated glazing are also described.
Claims15
A laminated glazing comprising,
- a first ply of a glazing material,
- a second ply of a glazing material,
- a film having an electrically conductive coating, the film being located between the first ply and the second ply, wherein the film comprises polyethylene terephthalate (PET) and
- a first busbar in electrical contact with the electrically conductive coating, the first busbar comprising an expansion portion, the expansion portion comprising a bridging busbar portion not in direct contact with the film or a gap in the first busbar, the first busbar being a split busbar with the gap occurring at the expansion portion,
- wherein the film includes a cut-out portion located at the expansion portion, the cut-out portion comprising a portion of the PET substantially coextensive with the expansion portion that is cut-out.
A method for manufacturing a laminated glazing, the method comprising
- a) providing a first ply of a glazing material,
- b) providing a second ply of a glazing material,
- c) providing a film having an electrically conductive coating, the film being located between the first ply and the second ply, wherein the film comprises polyethylene terephthalate (PET),
- d) providing a first busbar in electrical contact with the electrically conductive coating, and
- e) laminating the glazing,
- the first busbar comprising an expansion portion, the expansion portion comprising a bridging busbar portion not in direct contact with the film or a gap in the first busbar, the first busbar being a split busbar with the gap occurring at the expansion portion,
- wherein the film comprises a cut-out portion located at the expansion portion, the cut-out portion comprising a portion of the PET substantially coextensive with the expansion portion that is cut-out.
