 Comparison of advantages and disadvantages of heat insulation glass and shade louver

Hello, I'm Xiaobian. Heat insulation glass has special absorption, transmission and reflection ability to light and heat. It can play a significant energy-saving effect by using external wall windows and glass curtain walls of buildings. The commonly used insulating glass includes heat absorbing glass and coated

 By adding some metal ions or some substances to the glass, the heat absorbing glass once showed some colors and enhanced the absorption of light. The sunshade coefficient of the heat absorbing glass is lower than that of the transparent glass, and its sunshade principle is to weaken its entry into the room by absorbing solar energy.
Coated glass is to coat one or more layers of metal, alloy or metal compound on the surface of glass to change the performance of glass. According to different characteristics, it can be divided into heat reflecting glass and low radiation glass.
 
The thermal reflective glass is coated with metal film and some interference layers on the surface, so that the glass products can reflect more solar radiation to achieve the effect of sunshade and have rich colors. The thermal reflective glass has strong reflection to visible light and long wave radiation, and its function is to limit the solar radiation into the room.
Low-E glass is a low-E coating formed on the surface of glass by vacuum deposition technology. The function of low-e coating is to reflect the far-infrared radiation and effectively reduce the heat transfer coefficient of the glass; the second is to reflect the heat radiation in the sun and selectively reduce the sun shading coefficient; at the same time, compared with the heat reflecting glass, the low-E coating does not limit the penetration of visible light much.
However, the insulating glass has its own shortcomings. No matter in summer or winter, the insulating glass will block part of the solar radiation heat energy, so it can be used in the southern area mainly for heat prevention, but not in the northern area. Heat absorbing glass is actually the absorption of radiation, and the heat absorbed by the glass will eventually transfer to indoor and outdoor. The heat insulation glass not only reflects the heat of solar radiation, but also limits the entry of visible light, which will cause adverse effects on indoor lighting. In addition, too high reflectivity will lead to light pollution, too low and can not achieve the effect of energy saving and so on. The biggest disadvantage is that the sunshade and heat insulation are not adjustable, and the glass can not be removed once it is installed and not used. The sunshade and heat insulation have a great correlation with time, environment and climate. The sunshade and heat insulation need flexible adjustability, which is greatly insufficient in the heat insulation glass. On the contrary, for sunshade blinds, it is precisely the high-quality characteristics of sunshade and heat insulation.
 
The insulating glass itself is insulated, but it can't accurately adjust the amplitude of sunshade and heat insulation. Unlike the sunshade louver, the amplitude of sunshade and heat insulation can be adjusted by the angle of blade opening and rotation, so as to achieve the corresponding amplitude of sunshade and heat insulation to meet the best light and temperature comfort and energy-saving effect of the building.
 
Sunshade blinds are usually large panel blinds of various shapes composed of aluminum alloy materials. The common ones are electric shuttle blinds, flat blinds, etc. the shades of various colors can be customized later, and the most common one is silver gray. It is good for reflecting light and increasing heat insulation performance.
