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 the indoor temperature from rising, conserving
48 energy and reducing carbon emission.

Thermal radiation from the sun mainly contains ultraviolet, visible light and infrared radiation.
Emissivity (ƽ 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 Please scan QRcode
for more details
Guobiao standards, only coated glass with emissivity (ƽ value) lower than 0.25 can be labeled as Low-E
glass.

*Note Emissivity value: The value measures an object's ability to emit heat radiation after
absorbing it. The higher the value, the higher the ability to absorb and emit heat; the lower
the value, the lower the ability to absorb and emit heat, which means better heat insulation.

Fiberglass

Compared with metal support materials, fiberglass has excellent corrosion resistance and weather resistance, and at the same
time has the advantages of low cost, high strength/weight ratio, and longer service life. According to the different weaving structure and
characteristics of the glass fiber cloth, its products are very diverse and diversified, and it is also widely used for heat preservation, heat
insulation, fire prevention, and material reinforcement.

TGI's fiberglass products all meet RoHS and REACH requirements. For food contact products, a total of 4 meet US FDA standards; 8
meet EU 10/2011 regulation and have Germany's BfR approval; 2 meet France's requirements for drinking water (CAS). The quality of our
products meets CNS national standards. We print the CNS logos on labels according to different customer requirements. The packaging
labels of fiberglass fabric and fiberglass yarn are marked with RoHS compliance logos.
