A glass laminate includes an outer glass sheet having a first outer surface and a second inner surface, an inner glass sheet having a third outer surface and a fourth inner surface, and a polymer interlayer between the outer second inner surface of the outer glass sheet and the third outer surface of the inner glass sheet, wherein at least one of the inner glass sheet and the outer glass sheet has a thickness not exceeding 2 mm or less; the outer third surface of the inner glass sheet has flaws formed therein to weaken the glass laminated in the event of an internal impact on the fourth surface, an inner fourth surface; and wherein the inner glass sheet is chemically hardened with a depth of layer (DOL), and the flaws formed in the third surface have a depth of about 80% to 90% the depth of the DOL.
