Single silver Low-E glass single silver Low-E coated glass usually contains only one functional layer (silver layer), together with other metals and glass insulating compound layer lowe, total of 5 layer film. Double silver Low-E glass double silver Low-E coated glass having two functional layer (silver layer) lowe glass, together with other metals and compound layer to nine the total number of film layers. However, the technical process double silver Low-E glass is difficult to control much larger than a single silver. An 'energy-saving lighting systems' superiority must be reflected in the highest possible total solar energy through the glass doors lowe, while at the same time has the lowest 'u' value. By taking into account the gain and loss of heat energy, the establishment of the energy balance equation, 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, we can not meet the requirements of good energy balance. lowe glass hollow _ Yaohui quality (certification) _ Linyi lowe glass provided by Jinan Glass Co., Ltd. Yaohui.
