At present, the most recognized glass in the world is the so-called "low-emissivity hollow glass" (also known as Low-E hollow glass). The energy-saving glass is coated with one or more layers of silver on the surface of the glass, so that visible light is highly transmitted and heat is kept low. In this way, external heat can be prevented from entering the room in the summer, reducing the energy consumption of the air conditioner. In the winter, the heat in the room is prevented from leaking to the outside, reducing the loss of heating. In order to save energy throughout the year.

Using this low-e glass, summer air conditioning start-up time can be greatly reduced. The author's personal experience is that because I fear that being blown by cold air under the air conditioner will lead to a cold, I like to turn on the air conditioner. After the room temperature is lowered to a comfortable temperature, the air conditioner is turned off. The author found that in the hot summer of Changsha, if you use ordinary single-glazing, about half an hour, we must restart the air conditioning, otherwise the interior will be hot and difficult. With the use of new energy-saving glass, the indoor temperature can maintain a comfortable temperature for a long period of time. The time can reach about 3 hours. On the summer night, because the outside temperature is slowly declining, the insulation time can be longer, and basically it can be Sleep until dawn, do not have to open air conditioning again, thereby reducing the possibility of "air conditioning disease", but also greatly shortened the opening time of air conditioning, it will extend the life of air conditioning.

According to relevant statistics, in the winter, the amount of heat leaking through the window glass is one third of the heating consumption. If a new type of energy-saving glass is used, this “key area” of heat loss of windows can be a good insulation facility. It can increase the temperature of the room faster, and the holding time is more lasting, it can also greatly improve the comfort of the room.

New energy-saving glass has a more beautiful coat. The color of ordinary glass doors and windows is relatively monotonous, and the new energy-saving glass can provide colorless, transparent, gray, blue, blue-gray and other dazzling and generous colors for customers to choose, and further increase the aesthetic appearance of houses and buildings.
