| Abstract Scope |
LionGlass™ is a phosphate-based glass developed at Penn State to reduce the carbon footprint of glass production through carbonate-free batch chemistry and lower melting temperatures. This study evaluates LionGlass™ as a sustainable, high-performance substitute for conventional soda-lime-silicate (SLS) glass in glazing systems. Building on baseline compatibility demonstrated by nearly identical emissivity and thermal conductivity, Ag-based low-emissivity (low-e) coatings were applied to LionGlass™ via physical vapor deposition to enhance thermal insulation. Single-Ag coated samples exhibited emissivity values within the typical range of commercial low-e glasses, while maintaining high visible transmittance and low haze. Double- and triple-Ag coatings are being evaluated to further reduce solar heat gain while preserving visible transmittance. Prototype insulated glass units (IGUs) incorporating LionGlass™ are in development, with thermal performance, including U-factor and solar heat gain coefficient, to be benchmarked against commercial SLS IGUs. If targets are met, LionGlass™ could become a viable standard for next-generation sustainable glazing. |
