A process for manufacturing a laminated glazing unit so that it withstands a predetermined load, in which the unit includes at least one substrate having a glass function and at least one layer of polymeric interlayer. The process: obtains viscoelastic behavior of constituent material of the interlayer; calculates maximum value of at least one quantity representative of the loading resistance of the laminated glazing unit subjected to the predetermined load; adjusts dimensions of the unit such that the calculated maximum value of the quantity representative of the loading resistance of the unit is less than or equal to a permissible maximum value; and the or each substrate and the or each layer of interlayer are prepared and assembled to the adjusted dimensions.
