Abstract:
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.
