GLASS FOR FAÇADE 2021

76 77 GLASS FOR FAÇADE EDITION 2021 GLASS FOR FAÇADE EDITION 2021 KEY PERFORMANCE FACTORS Solar Factor (g-value) Percentage of solar energy transmitted through the glass. It measures the ability of a glazing to reduce the heating of the room. The lower the solar factor is, the better it helps to improve the comfort inside of the building. Shading Coefficient (SC) Ratio of the solar factor of a glazing unit to the solar factor of a clear float glass of nominal thickness of 3 mm to 4 mm (0.87). The lower the shading coefficient number, the less heat gain and thus more shading is provided.

When the selectivity of the glass is higher than 2, it gives you twice as much light versus heat. Light transmission (LT) Percentage of visible light directly transmitted through the glass. Reflection outside (LRe) Percentage of visible light directly reflected from the exterior glass surface. Reflection inside (LRi) Percentage of visible light directly reflected from the interior glass surface. Color rendering index (CRI) Ability of the glass to keep the colors the same as if they were observed without glazing. Measured with a scale from 1 to 100. A low CRI gives a poor representation of colors, and a high CRI gives a natural and bright representation of colors. Ug-value Measure of the heat loss by penetration of the glass. The lower the Ug-value is, the better the insulating properties are. Expressed in W/m 2 K.
