| Single Silver Low E Glass
Within the coating structure of single Low E glass, there is one silver coating layer. Single Silver Low E has been widely used in various buildings at different locations worldwide.
Features:
- Visible light transmittance - adequate indoor natural daylighting.
- Solar energy transmittance - a wide range of shading coefficient SC available, for different geological locations.
- High far infrared reflectance - low U-value, reduced thermal transfer due to temperature difference.
Double Silver Low E Glass
Within the coating structure of double silver Low E glass, there are two silver coating layers. While maintaining the same visible light transmittance, it has lower shading coefficient (SC), than single silver Low E glass. Meaning, it filters the sunshine as a cool lighting source to a larger extend and provides a solution to energy efficiency in design of high transparency architectures.
Features:
- Higher visible light transmittance - ensuring better natural lighting.
- Extremely low solar heat transmittance - effectively impeding solar heat radiation.
Triple Silver Low E Glass
Within the coating structure of triple silver Low E glass, there are three silver layers. As a result, triple silver Low E glass performs better against solar heat than double silver Low E glass and is currently the best silver based Low E in terms of high visible light transmission and energy efficiency. Triple silver Low E glass is suited for high transparency buildings with special solar shading requirement.
Bendable and Post-Temparable Low E glass
Ordinary Low E glass can not be bent and post-tempered after coating which limits larger scale application of Low E glass and promotion of energy efficient buildings. In view of the prevailing conditions and economic development in China, CSG has researched and developed Low E coatings made of new materials which can be bent and post-tempered after coating to meet the need of curved Low E glass in current architectural design practice. The new Low E glass has been widely used in a number of large buildings home and abroad. CSG has established a sound foundation for popularization of Low E glass and made new contribution to the undertaking of energy efficient buildings in China.
Features:
- Can be bent and post-tempered after coating.
- has optical properties and energy efficiency as ordinary Low E glass.

Production Capacity
Nowadays pursuing large daylighting glass area in architectural design becomes popular, and Low E glass is widely used for energy efficiency consideration. CSG is the first manufacturer of Low E glass in China. The Low E glass produced by CSG is outstanding in energy efficiency and in aesthetics with various colors, thus being the primary choice in architectural design. CSG owns ten Low E and Solar reflective glass coating lines manufactured by Leybold of Germany and BOC of USA with an annual production capacity of 25 million square meters.
- One of the three coating production lines in CSG Dongguan Architectural glass factory.
- One of the largest in Asia and equipped with 35 adjustment stations, can produced Solar controlled coating, Single Low E, Double Low E and Triple Low E.
Notes for use
Filling Argon (Ar) in the cavity of insulating glass may further lower the U-value, and raise the sound reduction index, Rw. Detailed data is available upon request.
When products with solar energy absorbance approaching to or above 70% are selected, it is recommended that the products be tempered or heat strengthened to prevent breaking due to the thermal stress.
The colors listed in the performance data table are outdoor natural reflective colors. When the background color changes, the observed reflective color may also change accordingly, therefore, the products should be observed at different locations from different angles for color selection.
