How the insulation glass take functions:

There are three ways of energy transfer in hollow glass: radiation transfer, convection transfer and conduction transfer.

Energy transfer

Radiation transfer is the transfer of energy in the form of radiation through radiation, which includes visible, infrared and ultraviolet radiation, just like the transmission of solar light. Reasonable arrangement of insulating glass and reasonable thickness of insulating glass spacer can minimize energy transfer through radiation form, thus reducing energy loss.

Convective transmission

Convection transfer is due to the temperature difference on both sides of the glass, which causes the air to drop on the cold side and rise on the hot side, resulting in air convection and energy loss

Conduction transfer.

Conduction and transmission is through the movement of molecule, which drives energy to move, and achieves the purpose of transmission, just like cooking with iron pot and soldering with electric iron, while the transmission of energy by hollow glass is accomplished through glass and air inside it. We know that the thermal conductivity of glass is 0.77W/mk. The thermal conductivity of air is 0.028 W/mk. It can be seen that the thermal conductivity of glass is 27 times higher than that of air, and the presence of active molecules such as water molecules in air is the main factor affecting the energy transfer and convection transfer performance of hollow glass. Therefore, improving the sealing performance of hollow glass is an important factor to improve the thermal insulation performance of hollow glass.

Advantage (PVC/UPVC window):
1.It takes up small room space ,beautiful vision ,competitive price and good sealing performance
2.Opening flexible ,since insert high-top roller ,slide easily
3.Glass window is easy to get day lighting
4.Window sash is good load carrying capability ,it is difficult to broken .
