  "textContent": "A window assembly includes a first pane of glass. The first pane of glass is chemically strengthened and exhibits a surface compressive stress of 400 MPa or more. A second pane of glass has a first major surface and a second major surface. The second major surface of the second pane of glass and a first major surface of the first pane of glass face each other. The second pane of glass includes 68-74 weight % SiO, 2-6 weight % MgO, 1-10 weight % CaO, 12-16 weight % NaO, 0-1 weight % KO, 0.8-2.0 weight % FeO(total iron), 0-1.25 weight % TiO, and 0-1.25 weight % CeO. A polymeric interlayer is provided between the first pane of glass and the second pane of glass. The window assembly exhibits a direct solar transmittance of 55% or less and a total solar transmittance of 65% or less.",
