Due to contingency and particularity of construction and regional differences in climate, seasons change in temperature and insulation system plexity, exterior insulation work there were many cracks, leaks and other quality problems, so these problems seriously impacted the normal use of the housing functionality, light damage lead to walls cracked,housing moisture,walls bee yellow and black that affect the appearance, serious damage appeared poly stupid empty Alice granular layer, rain down along the wall, in case of frozen ,emerged expansion, cracking, a direct result of external wall insulation layer off a large area, affecting the normal use, seriously affecting the architectural appearance of the image
