We will solve these problems by transforming the glass window.
Have you ever felt cold standing by the window even in a room with heating? This is typical cold radiation. The so-called "cold radiation" refers to the radiation caused by cold walls or windows to the body. This kind of radiation can make people feel uncomfortable and cause human body injury. The "cold radiation" of building is closely related to the thermal insulation performance of glass. The worse the thermal insulation performance of glass, the lower the inner surface temperature, and the more serious the cold radiation to human body.
In order to be comfortable in the cold winter, we need to keep the room warm. Therefore, the thermal insulation of the house is particularly important. Usually we use insulation on opaque roofs, walls, and floors to prevent heat loss and keep the house comfortable. But the energy consumption of doors and windows accounts for about 40% ~ 50% of the total, so the thermal insulation of windows is very important.
Doors and windows are the weak part of room insulation, what kind of glass should be selected to improve the insulation performance of doors and windows.
Vacuum insulating glass greatly improves the thermal insulation performance of doors and windows. The vacuum layer effectively insulates the convection and heat transfer of air. Low-E glass
significantly reduces the radiation heat transfer between two pieces of glass. Therefore, its thermal insulation performance is about 6-8 times that of single glass and 4 times that of insulating glass.
