The annual temperature difference of the inner wall of the outer wall is 5 times of that of the outer wall. The annual temperature difference of the outer leaf wall of the sandwich insulation structure is 8 times of that of the inner wall, and the outer wall of the self insulation wall is 8 times of the inner wall. Therefore, the methods of internal insulation, sandwich insulation and self insulation will reduce the stability of structural walls and shorten the life of structural walls.
