Low E glass application in the different climate areas
High latitude and cold climate
These areas have long winters, shallow winter temperatures, short daylight hours, and weak light intensity.
Firstly, the high-transmittance low emissivity glass can make maximum use of natural light due to its excellent light transmittance. Secondly, the indoor temperature is higher than outdoors, and the far-infrared heat radiation mainly comes indoors. Therefore, the low emissivity glass can reflect it indoors to keep the indoor heat from leaking.
Hot summer and warm winter area
These areas heat up quickly in summer, and the demand for heating in winter is lower than that of high-latitude regions. In addition, Double-silver or triple-silver low-emissivity glass can prevent outside heat from entering the room, reducing the energy consumption for air conditioning and cooling.
The outdoor temperature is higher than indoors, and the far-infrared heat radiation mainly comes from the outdoors. Low emissivity glass can reflect the mid-and-fort-infrared rays in the sunlight, allowing only visible light to pass through, turning the sunlight into a cold light source and preventing heat from entering the room. Thus, it can achieve the purpose of energy-saving and also meet the lighting needs of the room.
Hot summer and cold winter area
This area has four distinct seasons, significant temperature differences between winter and summer, and more variable climatic conditions. So we can use low-transmittance sun-shading low emissivity glass.
In summer, it can reduce the light transmittance of the glass and prevent outdoor heat radiation from entering the room. While in the winter, the light transmittance is relatively low, but it can meet everyday lighting needs. At the same time, it prevents indoor heating and other heat from passing outside. So it is necessary to consider heat dissipation in summer and keep warm in winter. Using suitable low-emissivity glass can find a balance between summer and winter.
