　　The solar energy’s usage and exploitation is the important item in the energy sources stratagem. The key of solar energy’s effectively using is that the solar energy can be directly absorbed, that is, the light transmittance of glass is better, the absorptivity of solar energy is higher. The solar glass which is developed by our company, its light transmittance is higher than any other glass , the new glass will add new gloss to the using of solar energy in our country.
　　The successful development of multifunctional transom window supplies new microcirculation concept, the direct changing air instead of traditional opening window which can exchange air through the 21°angle, so we won’t feel the direct blowing. In addition, the window screen can prevent mosquitoes and insects.
