Low-E laminated glass: It is a kind of laminated glass product consisting of Low-E coated glass and another piece of uncoated glass or Low-E coated glass, which is permanently bonded into a whole after high temperature and high pressure，through the interlayer. Low-E coating (offline Low-E coating) film is directly bonded with the interlayer and be protected.

The climate characteristics between the Tropic of Cancer and around are as follows: the outdoor temperature of the four seasons basically has change very little, which is between 25 ℃ and 35 ℃, and the temperature difference between day and night is also relatively little between 5 ℃ and 10 ℃; the indoor and outdoor temperature difference in such areas is small (about 10 ℃) all year. the most comfortable temperature is 20℃~28℃ for Human, cooling is required for indoor air conditioning all year. 

In energy saving design, the control of shading performance (SC) is the key of curtain wall glass, while thermal insulation performance (U value) become secondary factor, Low-E coated glass has excellent performance of reflecting radiating infrared rays, so it has excellent sunshade performance; take account of local climate characteristics, Low-E coated laminated glass was born.
