Building energy efficiency has become a country of major strategic issues, buildingexterior insulation system is currently the most widely used building exterior maintenance ofthe structure of energy-saving measures, but cracks appeared in the structure of the system inuse, the material loss and other problems, not only affects the outer wall insulation in normaluse, but also a threat to the lives and property of citizens. In this paper, Urumqi, Xinjiang, forexample, wind loads for cold regions EPS impact of security on the external wall insulationsystem were analyzed by thin plaster board EPS adhesive strength test, studied its adhesivestrength factors and make a comparative analysis, in experiments with increasing amount ofrelease agent, the bond strength between the adhesive and the primary wall has weakened thetrend will make use of excess adhesive release agent with the primary wall lower than thebond strength between the body specification. According FLUENT6.3software simulation ofthe EPS board and thin plaster external wall insulation system under wind loads on windspeed, pressure distribution patterns and laws, and analyzes the positive and negativepressure zone distribution of wind speed and pressure in the windward side of the building(positive zone) wind weakened to a certain extent; wind speed on both sides of the buildingthere is a certain degree of enhanced pressure weakened, this time inside and outside the EPSinsulation panels will generate a pressure difference, coupled with the effects of shearing,foreign wall insulation shedding adversely affected; less likely in the back of the buildingdestroyed by the wind load, some regions are calm area. For exterior insulation sheddingphenomena insulation stress calculation and analysis, and presents the main factors EIFSinfluence in windy load shedding.
