As the major raw materials of curtain wall, glass plays an important role on the energy saving performance. According the statistics, the heating loss through windows and doors account for around 50% of the refrigeration and heating in the whole building, and the heating loss through glass accounts for around 80% of the whole windows and doors. Then the glass energy saving becomes the hardest part in the construction energy saving. To improve the thermal performance of construction glass is very important.

The appearance of triple silver low e glass provide an ideal solution for the requirements of high transmittance with low heat transfer coefficient. There are three silver layers in the triple silver low e glass, the substrate layers and barrier layers could protect and separate the silver layer to take effects, which allowed the visible light transfer the glass easily while reflect the far infrared rays effectively. Normally there are 15 layers in the triple silver low e glass. Compared to normal float glass and single silver low e glass, it have superior light transmittance and excellent solar heat reduction.
