hard coated low-e glass is a kind of hard coating low emissivity one with high performance and energy efficiency. Its invisible outer layer can prevent from heat. 
1.The world leading online Low-E coating technology conducts online coating before glass cooling, and the coating becomes a part of glass after cooling. 2. The coating can be exposed in the air for a long time, doesn’t peel, get mildew or discolor under normal environment conditions, and can be stored in a long term, so as to greatly shorten the delivery period and accelerate project schedule. 3. It can be used singly or used for hollow glass or sandwich glass without removing edge coating. 4. It can be used for commercial and civil buildings, and has soft color and no aberration. 5. It is easy for hot bending, tempering or semi-tempering, easy to process like common glass, and durable.
Because the heat flows from the end with high temperature to the end with low temperature, it is easy to flow to outside from inside in winter, but from inside to outside in summer. The coating of online LOW-E coated glass can effectively inhibit the heat loss, make the sunshine reach the inside and indoor heat obtained from the sunshine and central heating stay without flowing outdoors, therefore, the interior is warmer and more comfortable in winter. However, in summer, it can prevent the exterior heat from entering the room to ensure higher refrigeration performance of indoor air-conditioner and reduce the living cost.
