<p>A high performance green glass composition containing at least 14.5% by weight Na2O, at least 10.5% by weight CaO, at least 0.5% by weight total iron (measured as Fe2O3) and is substantially magnesium-free, the glass thus produced having a ferrous value of at least 30% and a performance (light transmission minus Direct Solar Heat Transmission) of at least 28% at at least one thickness of 2.8 mm to 5 mm. The invention also relates to glasses made from such composition and to a laminated glass assembly in which two sheets of glass sandwich a polymeric material, at least one, preferably both, of the sheets of glass having such a composition.</p> |
