Low-E Glass
High Performance Glass with Advanced Coating Technology
Low-E Glass overview
Low-E Glass refers to glass with a low emissivity coating.
LEADER LOW-E GLASS refers to glass with a low emissivity coating. It reduces heat gain or loss by reflecting long-wave infrared energy (solar heat), therefore decreases the U-value & solar heat gain and improves the energy efficiency of the glazing. Because of its relative neutrality in appearance and energy efficiency, low-E glass is widely used in residential and commercial buildings and is expected to continue to increase in usage in the coming years.
Features
- High efficiency in energy saving and environment production.
- Wonderful performance in visible light transmission.
- Stable chemical and heat treatment performance.
- Stable mechanical performance for solid coat, high abrasion and scratch resistance.
