Abstract

A laminated glass pane is provided that includes a first glass sheet, a polymeric layer having a thickness between at least 0.5 mm and at most 1.7 mm, and a second inner glass sheet which has a thickness of at least 0.3 mm and at most 1.5 mm and is made of a lithium aluminum silicate glass. The polymeric layer is disposed between the at least two glass sheets. Furthermore, the glasses of the first and the second glass sheets are matched so that the temperatures at which the two glasses of the first and second glass sheets have the same viscosity in the viscosity range between 107 dPa·s and 1010 dPa·s differ from each other only by a maximum of 50° C.
