GLASS FOR FAÇADE 2020

85 Key performance factors 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. Light transmission (LT) Percentage of visible light directly transmitted through the glass. Reflection inside (LRi) Percentage of visible light directly reflected from the interior glass surface.

Selectivity (LSG) Ratio between the glass’ light transmission and solar factor. When the selectivity of the glass is higher than 2, it gives you twice as much light versus heat. 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. 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. 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. 84
