Abstract
The thermographic survey using thermal imager is considered to be a method for detecting the surface temperature differences between the delaminated area and the sound area of finishing materials on building walls. So, there exist some analytical studies using heat balance simulation on this method. However the numerical result obtained by a heat balance simulation can not always represent the easiness of judgement. In this study, by making simulated thermal image using finite element method with smoothing technique, the limitations of the method are discussed from a visual standpoint
