Abstract (en)
[origin: FR2773556A1] The invention concerns a silico-sodocalcic glass composition in particular for producing glazing sheets and comprising the constituents listed below with contents expressed in percentage by weight, defined within the following limits: SiO2 74-80 %; B2O3 0-2 %; MgO 0.3-4 %; CaO 1-10 %; Na2O 11-17 %; K2O 0.3-1.5 %; Al2O3 0.2-2 %; Fe2O3 0.2-2 % where Fe2O3 is total iron for a thickness of 3.5 mm, the global energy transmission TEis less than 46 %, and preferably less than 45 %, the ultraviolet transmission TU.V.ISO is less than 18.5 % and preferably less than 15 %.
