1、 Journal of China Institute of building, 2008, 137(8): 0732-9764. External wall insulation technology and energy-saving materials Zhangchuanzhou Dartmouth College Abstract: This paper used on the exterior of our current technology and energy-saving insulation material to be addressed. Vigorously pro

Key words: energy-saving building； materials The implementation of building energy conservation and environmental protection and en

3、ergy conservation policy and the main contents of the national economy and implementing sustainable development is an important component part. In such a series of energy conservation policies, regulations, standards and mandatory provisions under the guidance of Chinas energy-saving housing constru

4、ction work has been constantly deepened, energy conservation standards continuously, and the introduction of development, many new energy-saving technologies and materials, and in residential buildings to promote use. However, Chinas current level of building energy conservation, but also much lower

5、 than the developed countries, Chinas energy consumption per unit area construction climate is similar to the developed countries, three times to five times. Cold in the north building heating energy consumption accounts for the local society more than 20% of energy consumption, and the vast majorit

Therefore, the construction of this century, Chinas energy-saving construction is an important topic. In the construction of the external structure for the heat loss larger, exte

Therefore, the reform and building wall wall is the development of energy-saving technologies building energy-saving technology one of the most important part of the external wall insulation technology and the development of energy-savi

However, the use of thermal in

A further approach is the use of a dedicated fixed-absorbent will be difficult various insulation board fixed the outer walls, and then aluminium, natural stone, stained glass, and other pre-production plug in the keel, the direct formatio

This plug-in insulation installation time-consuming, difficult construction and construction-led occupation period, the main question can only after acceptance construction.
