Green Product - Flat Glass

The new generation energy-saving Low-E glass products can effectively block the radiation
from sunlight while allowing most sunlight to enter, which solves the problem of lighting and heat
insulation. This product also significantly reduces energy consumption from air conditioners. TGI’s
Low-E glass products are in compliance with CNS12681 standard and certified with ISO 9001 standard
and IGCC. Currently the product has been vastly used in buildings.

TGI actively promotes the green building concept. The Low-E Glass can reduce 30% energy
consumption of air-conditioning, and Low-E vacuum energy-saving glass insulation performance is
4-6 times of ordinary glass chip. The energy-saving products can better conserve energy than other
industrial products. Therefore energy-saving buildings will become a key to the energy conservation
energy of the country.

TGI’s Information

What is Low-E Glass?
Low-E (Low-Emissivity) glass is the best building material to reduce heat from sunlight as it
can deflect most ultraviolet and infrared radiation, preventing indoor temperature from rising,
conserving energy and reducing carbon emission.

Thermal radiation from the sun mainly contains ultraviolet, visible light and infrared radiation.
Emissivity (ε value, the lower the value, the higher the effectiveness for heat insulation) is glass’
ability to emit heat radiation from the sun.

Low-E glass utilizes its coating to block the heat radiation from the sun. According to China’s 59
Guobiao standards, only coated glass with emissivity (ε value) lower than 0.25 can be labeled
as Low-E glass.
