External Heat Insulation System of External Walls and Energy Conservation of Buildings

External heat insulation of buildings' external walls is a commonly adopted way of energy conservation of buildings.Rational allocation of different externalheat insulation materials of external walls and improvement of construction quality are the key to the guarantee of the effects of heat insulation and energy conservation.While improving the construction processes of the external heat insulation of external walls,striving to develop the new heat insulation materials with better property and adaptability should be encouraged to promote the technology for the development of buildings' energy conservation.
