In 2009, my company to Korea STACO company, established in the northeast city of Dalian Dalian Huali wool Co. Ltd, and put into operation in 2011. Dalian company covers an area of 100000 square meters, rock wool annual production capacity of 100 thousand tons. The company currently has 39 technical personnel, more than 100 managers, completed the ISO9001 system certification, ISO14001 certification and other certification, has become a number of well-known real estate partners.

  External wall insulation technology originated in Europe, China is from the middle of 1980s to start the pilot, and the technology is widely used in the field of construction. However, the current level of building energy efficiency is far lower than the developed countries, China's building energy consumption per unit area is still similar to the developed countries 3~5 times. So an important task of building energy saving in the century of China's construction industry. In recent years, as China's energy-saving housing construction work continued to deepen, and continuously improve energy efficiency standards, the introduction of the development of many new energy-saving technologies and materials, and vigorously promote the use in residential buildings. Among them, all kinds of foam insulation materials, such as EPS board, XPS board and foamed polyurethane sheet, which are used in the exterior wall insulation, have excellent performance. In recent years, due to the fire caused by the construction of the external walls continue to occur, a grade or material rock wool began to appear in the ranks of the external wall insulation materials.
