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. 1. A glass laminate structure comprising:a non-chemically strengthened external glass sheet;a chemically strengthened internal glass sheet; andat least one polymer interlayer intermediate the external and internal glass sheets,wherein the internal glass sheet has a thickness ranging from about 0.5 mm to about 1.5 mm, andwherein the external glass sheet has a thickness ranging from about 1.5 mm to about 3.0 mm.2. The glass laminate structure of claim 1 , wherein the internal glass sheet includes one or more alkaline earth oxides claim 1 , such that a content of alkaline earth oxides is at least about 5 wt. %.3. The glass laminate structure of claim 1 , wherein the internal glass sheet includes at least about 6 wt. % aluminum oxide.4. The glass laminate structure of claim 1 , wherein the internal glass sheet has a thickness of between about 0.5 mm to about 0.7 mm.5. The glass laminate structure of claim 1 , wherein the polymer interlayer comprises a single polymer sheet claim 1 , a multilayer polymer sheet claim 1 , or a composite polymer sheet.6. The glass laminate structure of claim 1 , wherein the polymer interlayer comprises a material selected from the group consisting of poly vinyl butyral (PVB) claim 1 , polycarbonate claim 1 , acoustic PVB claim 1 , ethylene vinyl acetate (EVA) claim 1 , thermoplastic polyurethane (TPU) claim 1 , ionomer claim 1 , a thermoplastic material claim 1 , and combinations thereof.7. The glass laminate structure of claim 1 , wherein the polymer ...
