Zhejiang Zhenshen Insulation Technology Corporation or ZES should be today the largest producer of high quality cellular glass in China. The company is driven by Mr. Chunhua Zhang, a real example of the Chinese dream. He started his career as a industrial thermal insulation worker, became contractor and immediately understood the benefits of cellular glass. He developed a process for cellular glass based on waste glass and upgraded to high  quality cellular glass with a special composition.

Today, ZES has a turnover of 700 million RMB or about 100 million euro, which is a very impressive realization. They are not only producing but also installing the thermal insulation. In that way, they can be very competitive. I would be pleased if I could write once Chunhua’s biography.

Chinese companies have the reputation to only copy but this is not true for ZES. They developed a nice patented  rendering system on their cellular glass to have a cellular glass concept for the building market. It looks that they are able to even render sculptured cellular glass.

Walter Frank (GLAPOR), Chunhua Zhang (ZES)  and  Andrei Zinovyev (STESS) are men with vision and a drive to ignite the cellular glass world for once and for ever.
