In recent years, national technology policies and standards to promote energy efficiency, exterior insulation technology is developing rapidly in the country has been some exterior insulation technology systems, these systems can solve the technical mesh outer facades Many syndromes caused by wall insulation, but our exterior insulation and wall insulation technology currently used energy demand there is a big gap. http://www.anpwanggebu.com/news/gs/383.html With energy conservation and environmental protection requirements continue to increase, maintain the structure of the building insulation technology is also increasingly strengthened, especially in the external wall insulation technology has been rapid development, and become an important building energy-saving technologies. Currently, the external wall insulation in buildings often used mainly exterior insulation and other methods, however, the construction process in different insulation methods, there have been a variety of quality problems, the problem of external wall insulation produced by the method of this article is intended to analyze, and thus the quality of the project play a preventive role.
