This is where SIPs really shine. One of the most important things about the building envelope is the for the insulation layer to be continuous. Minimum thermal bridging = good building envelope. And from then on it makes control of temperature and internal moisture a much simpler task. Photo below compares conventional timber stud construction with SIP when photographed with a thermal camera. Red is where the surface is warmer and black when it is colder. Both houses are warm inside, but on left side you can clearly see timber studs warmer than the insulation in between, while the SIP wall on the right side remains cool, keeping heat inside. Picture tells a thousand words..
