An 'energy-saving lighting systems' superiority must be reflected in the highest possible total solar energy transmission, while at the same time has the lowest 'u' value. By taking into account the energy gain and heat loss lowe windows, set up an energy balance equation lowe hollow glass, Ueg = UF-RFg. The best energy balance characteristic lighting system is vacuum magnetron sputtering 'Low-E' coated insulating glass. Although single-glazed solar transmittance its maximum, but it's 'u' value and 'Ueg' value but worst. Therefore lowe glass, can not meet the needs of good energy balance. Comparison of single silver LOW-E glass and double silver LOW-E glass, coated glass to limit any solar heat through at the same time will be different degrees of restrictions of visible light. Double silver Low-E glass than the single silver Low-E glass can block more solar heat radiation heat. In other words lowe glass colors, in the same light transmittance, the double silver Low-E has a lower shading coefficient Sc, to a greater extent to the sunlight filtered into a cold light. lowe glass color, Yaohui trustworthy, Heze lowe glass provided by Jinan Glass Co., Ltd.
