EPS external thermal insu- lation system under the influence of winter low temperature and summer high temperature envi- ronment is simulated by finite element analysis software. The simulation results show that high temperature and low temperature alternating effect is one of the main reasons for cracks and falling off of external thermal insulation wall; EPS board has excellent insulation properties; the deformation of the walls around and windows around is the most prominent, and therefore should be taken seriously. Through the numerical simulation of the external wall thermal insula- tion system, the regular of wall strain development is obtained, which provided scientific analysis and theoretical basis for nodes design and processing of the corresponding engineering disasters of external wall thermal insulation system.
