1. An automotive glazing having a vision area when installed as a window in a vehicle, the automotive glazing comprising:
an outer glass layer which is strengthened having at least one hole configured to receive mounting means for holding the automotive glazing on the vehicle;
an inner glass layer which is strengthened having a lower edge which extends below the vision area of the automotive glazing, said lower edge does not overlap the area captured by mounting means;
at least one plastic bonding layer disposed between the inner and outer glass layers, wherein the plastic bonding layer has substantially the same shape as the inner glass layer such that the inner glass layer and said at least one plastic bonding layer define a laminated section of the automotive glazing; and
a retention system comprising at least one adhesive layer and at least one reinforcement layer which overlaps the lower part of the laminated section and extends below such that it is captured by mounting means, wherein:
each adhesive layer of said at least one adhesive layer attaches a reinforcement layer of said at least one reinforcement layer to at least one surface of the outer or/and inner glass layer,
the thickness of the said at least one reinforcement layer is less than that of the at least plastic bonding layer,
said at least one reinforcement layer has a tensile strength at break greater than that of the at least one plastic bonding layer strength,
said at least one reinforcement layer is more thermally stable and less compressible than the at least one plastic bonding layer, and
the reinforcement layer is comprised of at least one of the following materials: polyimide, polyamide, carbon fiber composite, and titanium.
