FIELD: laminated glazing.
SUBSTANCE: invention relates to laminated glazing intended for use in transport (cars, helicopters, airplanes, etc.), including as car windshield. Laminated glazing comprises at least first lime-soda glass sheet, second glass sheet with smaller thickness than first glass sheet, and an intermediate polymer layer located between two glass sheets. Second glass sheet corresponds to the inner side and represents aluminosilicate glass containing the following oxides with content by weight lying in the ranges: SiO2 from 60.00 to 68.00 %, Al2O3 from 2.80 to 7.80 %, Na2O from 10.00 to 15.80 %, MgO from 4.90 to 10.10 %, K2O from 4.80 to 9.70 %, B2O3 from 0 to 3.20 %, CaO from 0 to 1.00 %.
EFFECT: technical result is providing asymmetric laminated glazing, having high mechanical strength, sufficient hydrolytic resistance.
