Radiation transfer is the transmission of energy through radiation in the form of radiation, including visible light, infrared and ultraviolet radiation, such as the transmission of the same sunlight. Radiation transfer is the transmission of energy through radiation in the form of radiation, including visible light, infrared and ultraviolet radiation, such as the transmission of the same sunlight. Reasonable configuration of the insulating glass and reasonable thickness of the insulating glass spacer, can minimize the energy transfer through the form of radiation, thereby reducing energy loss. The insulating glass and reasonable thickness of the insulating glass spacer, can minimize the energy transfer through the form of radiation, thereby reducing energy loss.

Energy transfer in three ways: the radiation transfer, convection transfer and conduction transfer.
Convection is due to the temperature difference between the two sides of the glass, causing the air in the cold side down in the hot side of the rise, the air convection, resulting in energy loss. There are several reasons for this phenomenon. First, poor sealing system of glass and the surrounding frame, resulting in the window frame inside and outside the gas can be directly exchanged to produce convection, resulting in energy loss; Second, Unreasonable hollow glass interior space structure design, resulting in hollow glass inside the gas due to the role of the temperature difference of convection, driven by energy exchange, resulting in the loss of energy. Third, constitute the entire system of the window inside and outside the larger temperature difference, resulting in hollow glass inside and outside the temperature difference is large, the role of air through the cold radiation and heat conduction, first of all in the insulating glass on both sides of the convection, and then passed through the whole of the insulating glass in the past, the formation of energy loss. Reasonable hollow glass design, can reduce the convection of the gas, thereby reducing energy convection losses.
Transmission through the movement of objects and molecules to drive energy to achieve the purpose of transmission, as with the iron pot for cooking and electric soldering iron, and the same thing, and hollow glass on energy transmission through the glass and its internal Air to complete. We know that the thermal conductivity of glass is 0.77W / m2k. And the thermal conductivity of air is 0.028 W / m2k, we can see that the thermal conductivity of glass is 27 times that of air, and the presence of active molecules such as water molecules in the air is the transmission and convection transfer of energy of the insulating glass Performance of the main factors, thus improving the insulating glass sealing performance, is to improve the insulating glass insulating performance of the important factors.

Sun Global Glass produce 5mm+5mm insulated glass, 6mm+6mm insulated glass, 8mm+8mm insulated glass etc.
