ABSTRACT:
A laminated glass having a low haze ratio and an excellent infrared rays shield performance and a glass composition suitable for use in a laminated glass and easy with respect to melting and molding works, which is a glass composition comprising 65 to 74% of SiO2, 0 to 5% of B2O3, 1.9 to 2.5% of Al2O3, 1.0 to 3.0% of MgO, 5 to 10% of CaO, 0 to 10% of SrO, 0 to 10% of BaO, 0 to 5% of Li2O, 13 to 17% of Na2O, 0.5 to 5% of K2O, 0 to 0.40% of TiO2and 0.3 to 2.0% of total iron oxide in terms of Fe2O3, on a weight basis, in which the sum of MgO, CaO, SrO and BaO is from 10 to 15% and the sum of Li2O, Na2O and K2O is from 14 to 20%, wherein the glass composition has a visible light transmittance of 80% or more as measured with the CIE Standard illuminant A and a total solar energy transmittance of not more than 62% at a thickness of 2.1 mm, and a laminated glass using a glass sheet made of that glass composition.
