Abstract
A glass laminate comprises an external glass sheet, an internal glass sheet, and a polymer interlayer formed between the external glass sheet and the internal glass sheet. The external glass sheet can be a thin chemically-strengthened glass sheet or can be a non-chemically strengthened glass sheet, the polymer interlayer can have a thickness of less than 1.6 mm, and the internal glass sheet can be a non-chemically-strengthened glass sheet or a thin chemically strengthened glass sheet.
Claims17
A laminated glass article, comprising:
- a non-chemically strengthened external glass sheet comprising a thickness of 2.5 mm or more, the external glass sheet providing an open convex surface of the laminated glass article;
- a chemically strengthened internal glass sheet comprising an alkali aluminosilicate glass, a thickness in a range from about 0.5 mm to about 1.5 mm, and a total alkaline earth metal oxide content of at least 5 wt. %, the internal glass sheet providing an open concave surface of the laminated glass article;
- and
- at least one polymer interlayer between the external and internal glass sheets, wherein both the non-chemically strengthened external glass sheet and the chemically strengthened internal glass sheet comprise distinct radii of curvature in two independent directions.
