What are the performance characteristics of single silver low glass? The sputtering process used to produce single silver low glass uses an argon gas stream to bombard the surface of the target with ions, and then the sputtered silver atoms overflow from the target to form a functional silver film layer. This process has many disadvantages: first, the sputtering speed is slow, and the overall film formation quality is poor due to the need to fill many defects before the silver atoms can form a functional film; Second, silver films do not have ductility, which allows them to yield or bend like metals.

These negative characteristics lead to the inferior thermal insulation effect of glass compared to crystalline glass. In addition, the sputtering process also reduces the strength of the glass, making it weaker than crystalline glass of similar size.

This is important for reducing the energy loss through glass in commercial and residential buildings, as heat from the sun is often a problem in these buildings. Therefore, low E (low emissivity) coated glass is increasingly used in commercial and residential buildings.

The use of low radiation coated glass in commercial and residential buildings has many benefits, including:

Low emissivity coatings help to reflect long wavelength infrared energy, reduce U values and solar thermal gain, and improve the energy efficiency of glass. The coating also helps prevent condensation on the glass surface, which can further improve energy efficiency and reduce building operating costs.

When combined with other thermal insulation measures, such as warm edge gaskets and argon filling, this coating helps reduce the overall U value of the glass. This leads to lower energy consumption, improved comfort, and lower maintenance costs within buildings.

This is also a good option for applications that need to control the amount of sunlight passing through glass windows, such as in office buildings and large commercial buildings. It is particularly suitable for applications with high sunlight and glare intensity, such as in coastal or tropical areas.

Compared to ordinary transparent glass, this type of single silver low glass has a lower emissivity level. The surface emissivity of ordinary glass is 0.84, while the emissivity of this low emissivity coating is less than 0.1.
