Abstract
A glazing includes a transparent polymer material sheet having a thickness of from 5 to 25 mm and a glass sheet having a thickness of between 0.5 and 1.5 mm, which are bonded to one another by an adhesive interlayer, the hardness of which at a temperature at least equal to −5° C. is at most equal to 70 Shore A and the thickness of which is a decreasing function of the thickness of the glass sheet, an adhesive interlayer thickness of 2.5 mm being sufficient for a glass sheet thickness of 0.55 mm and an adhesive interlayer thickness of 1.25 mm being sufficient for a glass sheet thickness of 1.25 mm.
