The coating on building glass can reduce plenty of solar heat entering the room through the glass, which is achieved by improving the reflection of the sun  (but not necessarily the reflection of visible light) and the heat absorption of the glass. The normal tinted coating glass play a role mainly via increasing the absorption of sunlight , these colors can absorb the solar heat on the glass, thus reducing the solar energy into the room. Compared to our building insulation glass coating, this coasting only makes an auxiliary effect.


Building glass coating is covered with a layer of metal, this metal coating can increase the light reflection and light absorption of glass, and greatly block the solar heat in the glass window. Similarly, in the winter,it can make temperature high indoor and the heat would not be lost outward to ensure comfortable temperature indoor.


In summer, the architectural glass film can block up to 85% of the solar heat into the indoor with UV blocking rate not less than 99% and good light transmission. In winter, it prevents more than 50% of the indoor heat dissipation outflow, so that the temperature indoor and outdoor is significantly different. When is the temperature cool in summer or hot in winter, we can save the power consumption of air conditioning or heating.


Because the energy saving effect, coating building glass has been very popular to be used in the building in city. What’s more, there are various colors for choice, for example, green coating glass, blue coating glass, grey reflective glass, bronze reflective glass and so on.
