In this regard, insiders show that the cost per square meter of LOW-E glass is only a dozen dollars higher than the usual glass, and the price of a million houses is actually very self-made. Developed countries have the legislative power to oppress new constructions that must use low-emission coated insulating glass to eliminate energy consumption. For example, Germany's LOW-E coated insulating glass has an average rate of 92% . Insiders said that China advocates the use of energy-saving glass in the scale of civil energy conservation planning, but there is no legislation to oppress the use of energy-saving glass. In the future, the government, enterprises, and mourners will have to be happy together. With the growth of the market economy, the promotion of people's living standards and the awareness of the surrounding environment, energy-saving glass will have a vast market in the future.
