We are Handan Aode Glass Decoration Co,.Ltd which is dealing with Low-e glass, tempered glass, insulating glass, bullet-proof glass, fireproofing glass, laminated glass, Clip silk glass, hot melting glass, art glass, coating hollow glass, hollow tempered glass, bulletproof glass, hollow glazed glass, hollow and hot melting glass, glass furniture.

Established in 2003, we are located in Handan City, HeBei Province. The machine and technology was bringed from England , and the corollary equipments were imported from Italy. What is more, we also buyed hot bending glass processing equipment from Finland. Now, we have three constituent companies called Yujia Energy-saving Glass Co,.Ltd, Chaoshuo Glass Co,. Ltd, Chisheng Car Glass Co,. Ltd.

We had finished the engineerings including: Beijing Air Port, the library in Haidian District of Beijing, Dinggu buildings in Zhongguan Cun of Beijing, China planetarium, Shanghai Jinpu interenational building and so on.

We had been honored by “consumer-trusted enterprise in hebei province”, “one of top ten in decoration industry”, “famous brand in Hebei province”.

Ths, sir, have a nice day.

Hard coat Low-E glass is manufactured by pouring a thin layer of molten tin onto a sheet of glass while the glass is still slightly molten. The tin actually becomes "welded" to the glass. This process makes it difficult or "hard" to scratch or remove the tin. Often this glass has a blueish tint to it.

Soft coat Low-E glass, on the other hand, involves the application of silver, zinc or tin to glass in a vacuum. The glass enters a vacuum chamber filled with an inert gas which is electrically charged. The electricity combined with the vacuum allows molecules of metal to sputter onto the glass. The coating is fairly delicate or "soft."

Furthermore, if silver is used (and it often is) this coating can oxidize if exposed to normal air. For this reason, soft coat Low-E glass must be used in an insulated glass assembly. Sealing the soft coating in between two pieces of glass protects the soft coating from outside air and sources of abrasion. Also, the space between the two pieces of glass is often filled with argon gas. The argon gas inhibits oxidation of the metallic coating. It also acts as an additional insulator.

The two types of Low-E glass have different performance characteristics. The soft coat process has the ability to reflect more heat back to the source. It typically has a higher R value. R values are a measure of resistance to heat loss. The higher the R value of a material, the better its insulating qualities. Look at Table 1 for a comparison of R values and the different types of glass.

Low-emissivity (Low-E) coatings on glazing or glass control heat transfer through windows with insulated glazing. Windows manufactured with Low-E coatings typically cost about 10%–15% more than regular windows, but they reduce energy loss by as much as 30%–50%.
