Sourcing Windows in China

Low-E glass and its advantages

Low-E (Low-Emissivity) glass is a type of energy-efficient glass that is coated with a thin layer of metal or metallic oxide. This coating helps cut down on the amount of ultraviolet (UV) and infrared (IR) light that gets through the glass. This can make a building more energy efficient, protect it from UV rays, and make it more comfortable.

China is the world’s largest producer of glass, and it is also by far the largest exporter of glass products, amounting to almost 25% of global exports alone. Companies all over the world are more and more likely to buy low-E glass windows from China.

The country is a good place to get low-E glass windows and other glass products because it has a lot of raw materials, advanced production methods, and low prices. In this article, we’ll talk about the benefits of low-E glass, why it’s a good idea to get it from China, and how to get good low-E glass windows from China.

Advantages of Low-E Glass

  • Energy efficiency: One of the main advantages of low-E glass is its ability to improve the energy efficiency of a building. The coating on low-E glass reflects heat back into the room in the winter and reflects it out in the summer, reducing the amount of heat gain or loss through the windows. This can help to lower heating and cooling costs, making the building more energy efficient.
  • UV protection: Another advantage of low-E glass is its ability to block UV rays. UV rays can cause damage to furniture, flooring, and artwork, and they can also cause skin cancer. The coating on low-E glass can block up to 90% of UV rays, which can help to protect the occupants of the building and their belongings.
  • Improved comfort: Low-E glass can also help to improve the comfort of a building by reducing glare and heat gain. This can help to make the interior of the building more pleasant and comfortable, especially during the summer months. Additionally, low-E glass can also help to reduce the amount of light that enters the building, which can help to reduce the need for artificial lighting.

Low-E glass is a versatile and efficient material that can bring a lot of benefits to a building, especially when it comes to energy savings and UV protection. Getting low-E glass from China is a great way to save money and make sure the quality is high.
