The use of high-performance glazing can contribute to thermal comfort in both winter and summer, through efficient insulation and solar control, and by eliminating the cold areas around windows.In winter, the cold stays outside and the heat inside, which reduces heating requirements. The high-performance insulation properties of Saint-Gobain’s glass, such as SGG PLANITHERM (Ug coefficient down to 1.0 W/m².K for a double-glazed unit and to 0.5 W/m².K for a triple glazed unit), limits heat loss while the greater transparency to solar radiation (high solar factor up to 71%) increases solar energy gains.In summer, the solar gains are reduced thanks to solar control and shading systems, which contains overheating and the need for air conditioning. Saint-Gobain Glass provides a range of coated glass, like SGG COOL-LITE well-suited for the design of building envelopes.Finally, an occupant working close to a window may feel a certain discomfort due to direct sunlight or coldnessProducts
