New innovations are increasingly required in the architecture industry to provide higher performance solutions. Glass compositions, which are almost infinite in number, can be selected by designers to achieve required performance levels in end applications. While soda lime silicate is the
most commonly used glass in architecture, other glass families such as borosilicates and aluminosilicates are also employed. This paper describes a new glass composition type, boroaluminosilicate glass, which falls outside the currently defined composition space of existing architectural glasses. Boro-aluminosilicate glass is well-suited for architectural applications with high resistance to thermal stress, bending stress, scratches, and chemical corrosion. With a viscosity compatible with fusion downdraw processing, it is ideal for producing glass panes that are thinner (less than one millimeter) and lighter than soda lime silicates while having a lower carbon footprint. The development of boro-aluminosilicate glass presents a promising solution for architectural applications requiring advanced glass materials.
