    Products Information

    Glass is one of the most popular and versatile building materials used today, and it provides a dramatic aesthetic. But the beauty of glass is pointless if the people inside the building are uncomfortable or if energy inefficiency makes the building too expensive to operate.

    Low-E coatings were developed to minimize the amount of ultraviolet and infrared light that can pass through glass without compromising the amount of visible light that is transmitted. A microscopically thin transparent coating allows Low-E glass to reflect exterior heat in warm temperatures and hold in heat during cold temperatures, making buildings light, bright and energy-efficient.

    We offer two types of low-e coated glass: Single silver Low-E and Double silver Low-E.

    Single Silver Low-E Glass

    Within the coating structure of single silver Low-E glass, there is one silver layer. Single Silver Low-E glass has been widely used in various buildings at different locations worldwide.


    Ø Visible light transmittance— adequate indoor natural daylighting.

    Ø Solar energy transmittance — a wide range of shading coefficient SC available, for different geological locations.

    Ø 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 layers. While maintaining the same visible light transmittance, it has lower shading coefficient, SC, than single silver Low-E glass. In other words, it filters the sunshine as a cool lighting source to a larger extent and provides a solution to energy efficiency in design of high transparency architectures. 


    Ø Higher visible light transmittance — ensuring better natural lighting

    Ø Extremely low solar heat transmittance — effectively impeding solar heat radiation.


    Prevention of thermal breakage :
    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 thermal stress.
