Low E Reflective Tempered Glass Insulated Curtain Wall For Commercial Building

Suitable for Parched Torridity Zone  On-line and Off-line Triple Sliver Low-E Reflective tempered Glass Insulated Curtain Wall

Low-E glass(Low Emissivity Glass), is a film product composed of multiple layers of metal or other compounds coated on the surface of the glass. The main functional layer of the Low-E film is the silver layer. Silver is one of the substances with low emissivity in nature. The nano-level silver layer is plated on the glass surface to reduce the emissivity of the glass from 0.84 to 0.02~0.12. Thereby filtering the sunlight into a cold light source. The coating layer has the characteristics of high transmission of visible light and high reflection of mid- and far-infrared rays, thereby filtering sunlight into a cold light source, which not only meets the requirements of natural lighting, but also ensures a comfortable room temperature.

After installing the triple silver Low-E hollow, the comfort of the human body can be improved. Since the human body's burning sensation is caused by solar radiation near infrared, the higher the gIR, the higher the infrared transmission, the lower the gIR, and the lower the infrared transmission. The infrared transmission gIR of Sanyin can be below 0.06, which means it is reflected off. Most of the heat, the burning sensation has been significantly improved, it is very suitable for use in hot areas, and the comfort level is greatly improved.

General Low-E glass only contains a pure silver layer (functional layer), the so-called single-silver Low-E glass.
The total number of layers of double silver glass reaches more than 9 layers, including two pure silver layers;
Three silver Low-E glass contains a total of more than 13 layers, including three pure silver layers.
Compared with single-silver Low-E glass, although double and triple-silver Low-E glass has higher processing technology requirements, its energy saving performance is much better than single-silver Low-E glass.

Function

Optical parameters: Under the premise of the same light transmittance, double silver and triple silver Low-E have lower shading coefficient Sc and heat transfer coefficient U,
Double-silver and triple-silver Low-E glass can block more solar radiation heat than single-silver Low-E glass, and filter sunlight into a cold light source to a greater extent.

Indoor comfort: Low-E glass can greatly reduce the heat exchange between indoor and outdoor environments through the glass, so when the air conditioner is cooling or heating, after the indoor temperature reaches the set temperature, the air conditioner can stay on standby for a longer time Status, thereby saving power consumption.
Not only that, the shading characteristics of Low-E glass greatly reduce the time of using curtains to shade, thereby improving indoor light comfort and creating a more transparent and beautiful indoor environment.
To make a simple analogy, in summer, a building with ordinary glass originally required air-conditioning and cooling for an effective operating time of 100 days. After using single-silver Low-E glass, the effective operating time for cooling required was shortened to 35 days, and if double-silver was used Or three silver Low-E glass, it only takes about 30 days or less, further saving electricity bills.
In the long run, although the use of double and triple silver Low-E glass increases a small amount of project construction costs, it greatly reduces the energy consumption during the use of the building, and the later energy saving can recover the investment in a short time. The cost of the increase.
