Saint-Gobain Glass has partnered with Danish textile specialist Kvadrat Shade to optimize the integration of glazing and sun shading, two key elements in modern facades. The collaboration aims to maximize the energy efficiency and performance of these materials.
Saint-Gobain has long developed glass with high light transmission and minimal solar energy absorption. However, effective sun shading is equally crucial for maintaining energy-efficient facades. This partnership seeks to perfectly harmonize Saint-Gobain's sun shading glass with Kvadrat's internal shading fabrics.
Rather than considering just the glazing’s g-value, Saint-Gobain now emphasizes the gtotal value (gtot), which measures the total solar energy entering a room when glass and shading are combined. A lower gtotal means reduced heat input and cooling needs.
Saint-Gobain’s Cool-Lite SKN and Cool-Lite Xtreme glasses are highly selective, blocking infrared heat while allowing visible light. Kvadrat’s ‘Clearview’ fabric complements this by reflecting infrared rays with its metallized surface, further reducing heat gain.
For example, Saint-Gobain’s DGU XTR 70/33 glass paired with Kvadrat’s Clearview 100 fabric achieves an exceptional gtotal of 0.12, a previously unattainable value for internal shading. This combination also improves daylight usage, temperature control, and air circulation, creating a comfortable and energy-efficient environment.
