When you are back at the office with your images downloaded to the computer it’s time to analyze, interpret and write your report supporting your interpretation. Is it missing insulation or not? Is it a moisture issue or not? Certain questions have to be asked and answered before you can make your conclusions. Remember, you might be asked later down the road to defend your interpretation. Do you have all of the facts relative to the circumstances under which that image was taken? For example, look at the right hand side of the image below. Is the wall insulated or not?
Can you tell whether the west wall (right hand side of image) is insulated or not? Let’s say that it is the summer season and it is hot outside. Then it is insulated. Let’s say it is a cold winter day with overcast skies. Then it is not insulated. Let’s say that it is a cold winter day with clear skies and the sun has warmed up the outside of this west wall surface to 100°F. Then it is insulated. Would you agree, then, that certain information is critical to your interpretation? I’ve put together of list of information that would be appropriate to think about. You would pick the specific items depending on the type of investigation you will be performing. Some of the information for a moisture investigations is different that information you will need for insulation and air leak investigations.
