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.
