What are the functional differences between low-e glass and heat-reflecting glass?
Thermal reflection glass is to reduce the shading coefficient of the glass and limit the direct solar radiation energy to enter the room through the glass, so as to reduce the cost of air conditioning and save energy.
Low-e glass limits the transmission of far-infrared heat radiation through the glass by reducing the U value of the glass, so as to reduce the convection conduction of heat energy through the glass.Meanwhile, low-e glass has a wide range of shading coefficient Sc adjustment, which can effectively control the direct solar radiation energy entering the room.
Can low-e glass be used in a single piece?
Vacuum magnetron sputtering made of low-e glass can not be used as a single piece, only synthetic insulating glass or laminated glass can be used.But its emissivity E is much lower, at 0.15, and can be as low as 0.01.
Low-e glass made by online coating process can be used as a single piece, but its emissivity E=0.28, which can not be called low-e glass technically (in science, objects with emissivity E≤0.15 are called low-radiation objects).
Low-e glass is most effective in the similar enclosed space formed by sealed insulating glass, because this enclosed space eliminates air flow on the low-e surface, thus making low-e glass work better.
Are the properties of low-e glass the same?
From a technical point of view, all low-e glasses process spectral curves in the same way, but not all have the same properties.The low-e glass produced by yaopi company is not only suitable for the cold areas in the north, but also for the warm tropical areas in the south.
