The inner sheet of the windscreen is of thickness in the range 0.5 mm to 3 mm and is toughened to a degree such that the central tensile stress in the glass is from 380 kg/cm.sup.2 to 1120 kg/cm.sup.2. The outer sheet may be an untoughened sheet of thickness 0.5 mm to 3.5 mm or a toughened sheet of thickness 0.5 mm to 3 mm and whose central tensile stress does not exceed 560 kg/cm.sup.2.
