Solar control glass is an advanced glazing solution designed to optimise natural light while reducing the amount of heat and UV rays entering a building. SunGuard Solar Plus glass combines many compelling benefits in one – high solar control and natural light transmission, yet also the ability to be. SCHOTT® Solar Glass utilized as cover glass, provides solid protection for high-performance solar cells. By combining lightweight, extremely durable materials with outstanding optical transmittance, SCHOTT® Solar Glass ensures reliable power supply and efficient operation of photovoltaic systems. Pilkington Solar-E™ and Pilkington Solar-E™ Plus are a range of solar control clear or body-tinted coated glass with medium light transmittance, low light reflectance, and low emissivity. Equivalent terms include: solar windows. Solar transmittance is defined as the ratio of solar radiation perpendicularly incident on window glass that is transmitted through the glass and calculated according to a formula specified in JIS R 3106 Testing method on transmittance, reflectance and emittance of flat glasses and evaluation of. Solar control glass providing abundant daylight to interiors.
