在冬季的热损失建筑物透过窗户是非常大的。据美国统计，建筑物通过建筑物的窗户能量损失约30的能源消费量帐户。在瑞典占了较大比例，约70％。中国的统计数字显示，约50％。实践证明，在国内和海外，提高保温隔热性能的建筑围护结构，特别是，改善建筑物窗户的保温性能，防止热损失是最经济和xxx的方法。绝缘建筑玻璃应用发挥了关键作用。根据资料，美国报告的5494KJ高层办公楼供暖窗户银空心每平方英尺每年消耗的能源利用，能源效率比单一的约2层玻璃/ 3（单层玻璃窗每平方英尺供暖能耗为17775KJ）每年。
随着国民经济的发展
，环保状况，节约能源，提高了越来越高的技术法规的制定一些相应的生活条件的需求。经修正后的1995年，“民用建筑节能设计标准”（以下简称新标准）规定的标准比80年代降低50％（其中承担30％的建筑物供暖系统，承担取暖能源建设20％），围延长结构建筑材料和传热系数门窗提出新的要求。单的传热单框双玻6W/m2.K钢复合窗的传热系数3.5W/m2.K，单箱双玻塑料窗的传热系数为2.6W/m2系数的双层玻璃窗户。光的窗户传热系数达到以下2.5W/m2.K中空玻璃必须使用。
根据新的标准，北京，天津，沉阳，大连，并通过了其他地方
双玻将能够满足要求。但是双玻容易产生结露问题，特别是当双玻密封不严，中空玻璃的内表面结一层雾性能容易受到影响。因此，用中空玻璃窗户，以取代双玻是发展的一个必然趋势。
虽然中国的对传热比原来的标准系数的窗口新标准
已大大改善，但仍，与国外相比差距。

中国建筑行业的保温玻璃的主要问题正在使用的建筑成本的增加。在增加的建筑成本可以很快恢复从节省能源。规划部门的建设techno中空玻璃使用经济计算结果表明，在寒冷的地区（东北，内蒙古）的绝缘能源的玻璃节能效果的使用，在4-5年将得到补偿增加的建筑成本。

Insulating glass windows to replace the ordinary双玻is an inevitable trend of development

Buildings in the winter heat loss through the window is very big. According to statistics of the United States, building energy loss through the windows of buildings accounts for about 30 percent of energy consumption. In Sweden accounted for a greater proportion, about 70%. China’s statistics show that about 50%. Practice has proved that at home and abroad, improve the building envelope structure of the thermal insulation properties, in particular, improve the insulation performance of windows in buildings to prevent heat loss are the most economical and most effective method. Insulating glass applications in the construction played a key role. According to the information the United States reported the use of high-rise office building windows silver hollow heating energy consumption per square foot per year for 5494KJ, energy-efficient than single-layer glass windows of about 2 / 3 (single-layer glass windows heating energy consumption per square foot per year for 17775KJ) .

with the development of our national economy, the state of environmental protection, energy conservation, improve the living conditions of increasingly high demand for a corresponding formulation of a number of technical regulations. Amended in 1995, “civil construction energy-saving design standards” (hereinafter referred to as the new standards) require the building heating energy than the standard 80’s to lower 50% (of which take up 30% of buildings, heating system to assume 20%), of Wai extended structure of the building materials and the heat transfer coefficient of windows and doors put new demands. Single-layer glass windows of the heat transfer coefficient for single-frame 6W/m2.K Steel双玻composite heat transfer coefficient of window 3.5W/m2.K, single-box双玻plastic window heat transfer coefficient for 2.6W/m2. K. Heat transfer coefficient of windows to achieve the following 2.5W/m2.K hollow glass must be used.

under the new standards, Beijing, Tianjin, Shenyang, Dalian and other places adopted双玻will be able to meet the requirements. But双玻easily lead to condensation problems, especially when双玻密封不严, the hollow inner surface layer of glass knot easily affected by fog performance. Therefore, the use of insulating glass windows to replace双玻is an inevitable trend of development.

Although China’s new standard on the windows of the heat transfer coefficient than the original standard has been greatly improved, but still, compared with foreign gap.

China’s construction industry the use of insulating glass of the main problems are the construction cost increase. The increase in construction cost can be quickly recovered from the energy-saving. Planning departments of the use of insulating glass building techno-economic calculations show that the cold in our region (northeast, Inner Mongolia) The use of insulating glass made in energy-saving effect, in 4-5 years will be compensated the increase in construction cost.
