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 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
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

Our Fiberglass Department actively promotes the application of fiberglass in daily life products.

Compared to metal supporters, fiberglass has better resistance to corrosion and elements. Fiberglass is
low-cost, more durable and has a great strength/weight ratio. Different types of fiberglass, based on their
structures and features, are extensively used in thermal insulation, heat insulation, fireproof material, and
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.
