An asymmetric glazing laminate (34) that includes an outer transparency (36) and an inner transparency (50) that are maintained together by an interlayer (44). Outer transparency (36) has a nominal thickness (42) of 2.1 mm and inner transparency (50) has a nominal thickness of 1.2 mm. The asymmetric glazing has greater stone impact resistance and lower per unit weight than symmetric glazing laminate (10) in which the outer and inner transparencies (12 and 26) each have nominal thickness of 2.1.

A process for making a symmetrical glazing that has the same nominal weight as an asymmetrical glazing that has been determined to afford enhanced glazing strength, glazing rigidity, or stone impact resistance wherein the symmetric glazing has improved acoustic attenuation over coincidence frequencies of the asymmetric glazing design.

A roof glazing includes at least one first pane having a first primary surface and a second primary surface, at least one light source adapted to emit light, at least one light coupling system, wherein the at least one light source is optically connected to the first primary surface of the first pane via the at least one light coupling system such that light from the at least one light source is to be coupled into the first pane, and at least one light outcoupling system for outcoupling light from the first pane via at least one of the first and second primary surfaces, wherein the roof glazing is a vehicle roof glazing.

The present invention relates to a laminated glass with improved residual load-bearing capacity. The laminated glass comprises at least two sheets of glass or glass-ceramic joined to one another through an interlayer. The laminated glass may be used in particular as overhead glazing. The laminated glass is particularly suitable for use as safety glass and/or fire-resistant glass.
