Abstract
A laminated automotive glazing unit including two glass sheets joined by a thermoplastic interlayer sheet, a system of conductive layers applied to one of the sheets, and including on an edge of the same sheet a substantially opaque masking strip, making contact with the glass sheet, the system of conductive layers covering at least partially the masking strip. The glazing unit further includes busbars for supplying electrical power, the busbars making contact with the layer system in the portion covering the masking strip. The masking strip includes a set of layers that absorb visible radiation, the layers being formed by cathodic sputtering.
