Abstract: A formed laminated glazing for a vehicle, includes two sheets of glass of different thicknesses separated by an interlayer made of polymer material, the thickness E1 of the thick glass V1 being such that 1.4 mm ≤E1≤3.9 mm, the thickness E2 of the thin glass V2 being such that 1.1 mm≤E2≤2.6 mm, the thickness E3 of the polymer material M being such that 0.3 mm≤E3≤1.2 mm, the total glass thickness EV being such that 2.5 mm≤EV≤5.7 mm, the ratio of the thicknesses E2/E1 being such that 0.34≤E2/E1≤0.9. This glazing combines rigidity, acoustic performance and ease of manufacture.
